Description

      In the present invention, clean natural stone or the like is fixed on a concrete surface or an existing floor surface with a synthetic resin such as urethane or unsaturated polyester. It relates to resin surface materials used for outdoor floors, indoor floors of stores, buildings, condominiums, and houses.

Conventionally, resin pavement has a particle size of 4mm ~ on pavement such as concrete surface and asphalt surface.
It has been constructed by using a method that makes clean natural stones of about 10 mm hardened with epoxy resin or urethane resin to make them water permeable. Recently, in order to reduce the price as much as possible, the particle size of natural stone is made as small as 2 mm to 4 mm, and the construction thickness is finished thinly.

      Conventionally, resin pavement has only had natural stones hardened with epoxy resin or urethane resin, so the bending strength was weak because the stones were just point-bonded.

      Conventional resin pavements simply harden natural stone with epoxy resin, urethane resin, etc., so the stone and the floor surface are only spot-bonded, and the bond strength with the floor surface is weak and easy to peel off was there.

      Unsaturated polyester resin is a two-component resin. When about 1% of the curing agent is mixed, the resin hardens in 10 to 30 minutes, so the resin hardens in the middle of the work and the workability is extremely poor. So it was not used for resin paving.

      The conventional resin pavement has a gap between stones, so there are drawbacks such as dirt and scales that accumulate in places with poor sunlight and poor drainage, soiling easily, and grass growing.

      Conventional resin pavements are not used on indoor floors because they are easily soiled and cannot be wiped with water.

Since conventional resin pavements have many voids in the structure, they are not only easy to get dirty but also weak in the structure itself.

The present invention has been made in view of such circumstances, and its purpose is as follows:
By adding at least one of sand-like pebbles, colored glass, ceramics, transparent glass sand, etc. to the resin pavement structure, it is possible to create a structurally strong water-permeable resin pavement material. Therefore, it is intended to provide a resin pavement that is resistant to contamination by completely filling the gaps in the structure, further increasing the adhesive strength and bending strength, and making it impermeable. In addition, it is possible to reduce the cost of materials by making it possible to construct even cheaper unsaturated polyester resins compared to urethane resins.

      In conventional resin pavements, aggregates such as natural stone were only hardened with synthetic resin such as urethane or epoxy, so the aggregate and aggregate, and the aggregate and floor were point-bonded and structurally weak. . Therefore, in order to strengthen the structure, sandstone pebbles with a particle size of 4 mm or less, colored glass, ceramic, transparent glass sand with a particle size of 2 mm or less, etc. are used as a binder for aggregates. Invented the use of synthetic resin such as urethane and unsaturated polyester resin.

      By mixing sandstone pebbles, colored glass, ceramics, etc. as a connecting material with natural stones, it is possible to add designs of various colors to natural stones and also to act as a connecting material for natural stones. . In addition, transparent glass sand with a particle size of 2 mm or less acts as a connecting material for natural stones, sand-like pebbles, colored glass, ceramics, etc. and is transparent, so natural stones, pebbles, colored glass, ceramics, etc. There is a work that does not impair the beauty.

      By filling between natural stones with at least one of sandy pebbles with a particle size of 4 mm or less, colored glass, ceramic, transparent glass sand with a particle size of 2 mm or less, the strength is increased and the natural stones are peeled off. Make it stronger. However, at this stage, there is a void portion of about 18% to 30% in terms of volume ratio in terms of structure, and the surface material is water permeable because it is not a completely dense structure.

Structurally, a water-permeable surface material with voids has the disadvantage that dirt and dirt accumulate in the voids and become dirty. First, sprinkle transparent glass powder over the surface material, and then brush or brush. Rubbing with a roller brush, etc., fill the voids and surface recesses of the structure with transparent glass powder as much as possible. Next, the surface of the structure is filled with synthetic resin by painting the surface with a synthetic resin such as urethane or unsaturated polyester resin. In this way, an impervious architectural or construction surface material that is not easily soiled by dirt or water is formed. Glass powder is cheaper and less expensive than unsaturated polyester resin

Since it is 1/5 or less, if a large amount of glass powder is used, the overall cost can be reduced.

      Glass powder with a size of 2 mm or less is used for the transparent glass powder used to fill the voids in the water-permeable surface material that has structural voids.

According to experiments, the amount of transparent glass powder used to fill the voids and surface recesses of structurally voidable water-permeable surface materials is determined by the volume of the entire surface material.
The required volume of glass powder is about 3% to 9%. This is because the void portion is a complex structure, so that filling is difficult, and it is possible to fill the glass powder with about 15% to 30% of the volume of the void portion.

      After filling the voids with transparent glass powder, the remaining voids are filled with synthetic resin for filling. Synthetic resins for filling use synthetic resins such as urethane and unsaturated polyester, but if the surface material is white natural stone or if you want to make the surface material lighter, use synthetic resin such as urethane or unsaturated polyester resin. Mix a white or other bright colorant into the resin.

Unsaturated polyester resin is used as a binder to harden natural stones as well as fillers.
It can also be used. Conventionally, unsaturated polyester resins are two-part, and the correct usage is to add about 1% of curing agent at normal temperature and cure it for about 10-30 minutes.
However, the curing time can be adjusted to about 2 hours to 10 hours by reducing the curing agent to 0.5% or less or by adding a curing retarder. by this ,
It can also be used as a binder to harden natural stone.

      According to the first and second aspects of the present invention, at least one of sandstone pebbles having a particle diameter of 4 mm or less, colored glass, ceramic, transparent glass sand having a particle diameter of 2 mm or less is provided between natural stones. Therefore, it is possible to provide a water-permeable resin surface material whose bending strength is about 50% or more stronger than that of a conventional water-permeable resin pavement made of only natural stone.

      According to the first and second aspects of the invention, at least one of a natural stone as an aggregate and sandy pebbles as a connecting material, colored glass, ceramic, glass sand, etc. is used as an unsaturated polyester with a low cost. Since it can be bonded and solidified with a synthetic resin, it is possible to provide a water-permeable resin surface material that is cheaper than conventional water-permeable resin pavement materials.

According to the third and fourth aspects of the invention, since the filler can be coated from above the water-permeable resin surface material, it can be bonded and solidified with a synthetic resin such as unsaturated polyester at a low cost. The cost can be greatly reduced.

      According to the third and fourth aspects of the present invention, at least one of natural stone, sandy pebbles, transparent glass sand, and the like is bonded and solidified with a synthetic resin such as urethane or unsaturated polyester resin, and then the upper portion thereof is formed. Furthermore, since it is painted with a synthetic resin such as unsaturated polyester, not only can fine voids be filled with synthetic resin to form a surface material for construction or construction that does not allow water to penetrate, but the synthetic resin also has fine voids. By filling in, the bending strength can be increased more than twice. Also, the adhesive strength can be increased by about 50% or more. As a result, it can be used for a parking floor or the like.

According to the third and fourth aspects of the invention, it is possible to maintain a clean appearance that is difficult to get dirty with dirt and water.
A building or construction surface material can be formed. Also, it can be easily removed by washing with a polishing machine such as a polisher, and it can be easily removed by wiping with a scrubber, so it can be used on indoor floors.

      Hereinafter, an embodiment of a method for forming a building or construction surface material according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a structural diagram of an architectural or construction surface material having a relatively small particle size of natural stone as an aggregate. Natural stone (symbol 1), which is an aggregate, uses relatively small aggregates with a particle size of 4 mm or less.
I use it. Sandy pebbles with a particle size of 3 mm or less and transparent glass sand with a particle size of 2 mm or less used as a binder are used in a weight ratio of about 40 to 120% with respect to natural stones.

      When sandy pebbles and transparent glass sand used as a connecting material are accurately analyzed, they can be analyzed from small particles having a particle diameter of 2 mm to 3 mm (reference numeral 2) to fine particles having a particle diameter of 1 mm to 2 mm ( 3) Since fine particles with a particle size of 1 mm or less (reference 4) vary moderately, small sand enters the gap between natural stones and fine sand falls between the small sands. As the finely divided sand enters the remaining fine gaps, the gaps are filled without gaps, and the bonding area between the individuals increases, thus forming a solid building or construction surface material as a whole. can do. Although the thickness of the construction or construction surface material of the present invention is as thin as 3 mm to 4 mm (symbol 5), it has sufficient strength.

The features of the building or construction surface material in FIG. 1 are strong and have sufficient strength even if the thickness is small, so that even a thickness of about 3 mm to 4 mm can be used. In addition, the gap between the natural stones and the natural stones is filled with sand and transparent glass sand, which makes it difficult for mud and debris to adhere and the natural stones are hardly peeled off. In addition, since the sand and transparent glass sand are attached to the surface, the feet do not slip. The adhering glass is transparent, so the natural color of clean natural stone is not lost. Workability is easy because it is made of glass sand, and natural stones do not get tangled and sticky. Thickness is

Since it is as thin as 3 mm to 4 mm, the material cost is reduced and the amount of work is also reduced, making the work easier.

As a feature of the building surface material for construction or construction shown in FIG.
be able to. Rain water can be swallowed into the ground by making the base pavement permeable or making a hole in the base concrete.

FIG. 2 is a diagram of a surface material obtained by making the building or construction surface material of FIG. 1 water-impermeable. Of FIG.
After forming a water-permeable surface material, the resin is cured or semi-cured, and then the fine and transparent glass powder (symbol 8) with a particle size of 1 mm or less is used to close the fine holes and dents on the surface. Paint a synthetic resin (symbol 9) such as unsaturated polyester. As a result, the water-impermeable impervious water can be obtained, and an architectural or construction surface material that is difficult to get dirty can be formed.

      Synthetic resin (symbol 9) such as unsaturated polyester that is painted from the top enters the fine holes by capillary action and is firmly solidified with the synthetic resin to the inside of the structure. The bending strength of the surface material can be further doubled and the adhesive strength to the floor can be increased by about 50% or more. Moreover, since the fine voids can be filled with the synthetic resin, the surface material can be made difficult to get dirty.

After forming the water-permeable surface material of FIG. 1, the transparent glass powder sprinkled from above,
The amount of synthetic resin such as unsaturated polyester applied from above can be arbitrarily adjusted. For example, without using transparent glass powder, if the amount of synthetic resin such as unsaturated polyester applied from above is halved or less, the strength is relatively strong and water-permeable building or construction
A surface material can also be formed.

      If unsaturated polyester resin is used for the binder that hardens natural stone and the synthetic resin (symbol 9) that is painted from above, the purchase price is reduced to half or less compared to urethane resin, which can greatly reduce the cost.

      For transparent glass sand, waste fluorescent tube glass scraps crushed to 2 mm or less, transparent waste bottle glass, waste plate glass, etc. that have been crushed and cut to 2 mm or less are used.

      In order to demonstrate the blending effect of sandy pebbles and transparent glass sand, which are the binders according to the present invention, and the effect of transparent synthetic resin coated from above, a strength test was conducted. FIG. 3 shows the strength test results of the building or construction surface material according to the present invention.

In Fig. 3, the test materials A, B, C, D, E, and F are compared in the particle size of natural stone as aggregate.

Is a small surface material for construction or construction, and the blending ratio of sand-like pebbles and transparent glass sand as a connecting material is 50% for A and B, 40% for C and D, and E and G for An experiment was conducted to see how much the strength differs when 20% and F 2 and H are 0%. F and H are conventional products that do not contain a binder.

In FIG. 3, test materials G and H are for building or construction having a relatively large particle size as an aggregate.
It was a surface material, and the experiment was conducted to determine the difference in bending strength when the mixing ratio of sandy pebbles as a binder and transparent glass sand was set to 20% for G and 0% for H, respectively. . H is a conventional product that does not contain a binder.

      The test results in Fig. 3 show that the test materials A, B, C, and D have a bending strength of more than twice that of the conventional products F and H. Therefore, the sand material as a connecting material and the transparent glass sand are stronger. It turns out that it is useful for improvement. Further, it can be seen that the bending strength of sand material as a binder and transparent glass sand is improved by 40% and 50% rather than 20%.

      The test results in FIG. 3 show that the test materials E and G have a bending strength of 1.5 times or more compared to the conventional products F and H, so that 20% of sandy pebbles and transparent glass sand are used as the connecting material. It can be seen that even with a small amount, the bending strength increases to 1.5 times or more.

      3 shows that the test material A has a bending strength of 1.5 times or more and an adhesive strength of 1.5 times or more compared to B, and the test material C has a bending strength of 1 compared to D. .5 times or more and adhesive strength is 1.5 times or more. Thus, it can be seen that the unsaturated polyester resin coated from above increases the bending strength by 1.5 times or more and the adhesive strength by 1.5 times or more.

      Conventional resin pavement was mainly used for approaches and sidewalks, but with this invention, the strength has been greatly improved, so it can be used for garages and garages.

The conventional resin pavement was permeable to water, so it could only be used outdoors.However, the present invention has made it impermeable and made it easier to remove dirt by wiping with water. Has become available for indoor use. The range of use has expanded significantly, including halls, corridors, and stairs for stores, buildings, mansions, and houses.
