Manufacturing method of building foundation materials

The present invention relates to a base material such as when painting or applying a ceramic material such as mortar or tile on the surface of a structure such as a building, or when blowing a mounting material such as lysine or starco, It relates to the production of the base material.

Conventionally, construction such as mortar coating or tile pasting of wooden houses generally apply waterproofing paper such as taal felt on the base of wood, etc. After fixing the metal mesh to the underfloor material with a swivel or the like, the tiles were mortar-coated or tiled on the mortar-coated surface. However, since all of them were done by hand, the human hands went much longer, and in the air for a long time Was costing. In addition, since the mortar itself is only held in the base material through the metal mesh, spider-like cracking is liable to occur due to shrinkage caused by hardening and drying of the mortar. In addition to damaging the aesthetics, in the case of an outer wall, these cracks cause the end to be bad or fall off after raining, and thus deteriorate the function of the wall, and deteriorate structural materials such as foundation materials, columns, and foundations. There was a flaw, such as the (腐朽), or the occurrence of termites. As another method, asbestos or the like is electrostatically capped on the surface of the waterproof sheet of the polymer of ethylene vinyl acetate to give the effect of conventional waterproof paper and metal mesh, or non-vulcanized on the surface of plywood substrate ( A mixture of aggregates, such as silica, asbestos, and calcium acid, is added to the non-gum rubber liquid so as to form a rough surface roughening of a roving type. Although the effect of the mesh is integrated, it is proposed, but the former cannot be fixed to the base material by the swivel, etc. in the construction, and it needs to be fixed by the adhesive material one by one, which required a lot of time for the adhesive work. In addition, defects that are difficult to install due to the use of solvent-type adhesives also cause health problems for the workers, and the attachment of mortar is maintained only with sheet-fed asbestos. The weak adhesion, and sometimes even caused by a defect implanted could not keep the mortar over a long period of time. In the latter case, since the surface of the aggregate is covered with a non-vulcanized rubber film, the adhesion of mortar is very poor, and therefore, it is impossible to thicken it, and furthermore, since the mortar of the long-term mortar as described above is not maintained It could not be used except for special mounting materials developed for use, and the main rubber layer was non-vulcanized, so it had deterioration in a relatively short period of time.

상이머 스테이플상의 요철조면을 형성하도록 도포하고, 상기 조면이 무너지지 않도록해서 건조 고화시켜 몰탈 도벽(塗壁)등의 건축 밑바탕재료를 제공하는 것이다.This invention is made | formed in order to improve this fault. In other words, the present invention is based on cement, emulsion or synthetic rubber latex and water which is thermoplastic resin in one or two of fine powder of combustion residue and water-soluble fiber or water-soluble synthetic resin powder containing silica and carbide of wood. To obtain a paste-like coating composition kneaded with stirring, and the coating composition was applied to a coating apparatus such as a roll coater on the surface of a substrate such as a wooden board such as plywood or an inorganic plate such as asbestos cement plate. By, Yuzu

It is applied so as to form an uneven rough surface on a reamer staple, and dried to solidify the rough surface so as not to collapse, thereby providing a building material such as a mortar coating wall.

In addition, when the present invention is described in detail, cement is mainly used as a coating composition to be applied to substrate surfaces such as plywood, and mortar and the like are applied to the surface of the base material and the hydrate when the cement is cured. The metal salt which reacts with the harvest when it hardens and hardens mutual bond, and melt | dissolves in water, such as kali, calcium, and magnesium, and produces a hydroxide to improve the adhesion of mortar, etc. Combustion residues of wood materials containing carbon which fixes needle-shaped crystals of the hydrate and the flowability of the coating composition, to prevent bridging and strength after drying and solidifying the coating composition To improve the viscosity of the coating composition and the silica to react with the hydrate of the cement in the cement and mortar to improve the adhesion between the coating composition, 1 or 2 of water-soluble fibers such as met cellulose (MC) and fibrous glycolic acid sodium hydroxide (CMe), or water-soluble resin powder such as polyvinyl alcohol, which impart cohesion between itself and the present base material and mortar. And thermoplastic resin emulsions such as vinyl acetate resin and acryl resin to impart adhesion between the coating composition and the substrate and to impart waterproofness and equatorial flexibility to the coating composition. Synthetic rubber latex and a suitable amount of water are stirred and mixed, kneaded well to form a paste to obtain a coating composition of the present invention.

In addition, in the coating composition of the present invention, a frying agent that predominates silica powder in place of silica may be used. In addition to burning residues of wood materials, burning residues of plant material such as rice straw and barley straw straw may be used. Alternatively, a powder obtained by mixing carbon, such as metal salt and charcoal, which is dissolved in an animal such as cali, calcium, and magnesium and may be used as a hydroxide, may be used. In addition, when inorganic fibers such as asbestos are used as the coating composition, mortar adhesion can be further improved.

The coating composition thus obtained is made of a base plate such as plywood or a sub-plate such as asbestos cement board, and the surface area of the surface coating material such as mortar is coated on the surface by a coating apparatus such as a roll coater. To increase the anchoring effect and to increase the adhesion of the surface coating material, and to apply a staple uneven surface to form a roughened surface, followed by drying to obtain the building material of the present invention. In order to form the roughened surface of the yuzu chopped staples, the relationship between the viscosity of the coating composition and the spacing between the roll coater and the transfer roller of the roll coater and the thickness of the base plate It can be formed by adjusting the rotational ratio of the transfer roller or the application roller and the copper roller at an equator.

According to the present invention, since the coating composition and the surface form thereof are formed as described above, not only the bonding of the coating composition itself but also the adhesion between the substrate and the coating composition and the cement of the coating composition and mortar are chemically In addition, it is excellent in the initial adhesiveness such as mortar by the uneven rough surface on the citron chopped staples. In addition, since the porosity and water retention of the carbohydrate in the coating composition promote the production and seedling effect of cement hydrate, the base material, the coating composition, the coating composition and the mortar are adhered to each other, so that the three parties are integrally formed. Thus, long-term maintenance of mortar was possible. In addition, since the coating composition of the present invention has moderate flexibility, it also sufficiently buffers against shrinkage cracks caused by hardening of mortar or cracks caused by external forces such as stretching and impact of the substrate, and the substrate and the coating composition on the entire surface of the substrate. Since the coating composition and the mortar are firmly attached to each other firmly, it is possible to prevent the group sequence due to the above causes. In addition, since the coating composition of the present invention has waterproofness, it is possible to prevent cracking of mortar, so that, for example, in the case of the outer wall, the structural material such as the base, the base, or the like may be thickened by permeated water. Prevent the cause, etc. Therefore, the present invention can be applied to the use of such as the outer wall under the damage of the function, the base of the mortar, etc. are formed just by applying to the structure of the building, etc., directly applying and applying ceramic materials such as mortar Or it can be mounted, so there is no remnant in the field work, and it has the effect of constructing durable mortar walls with short air. Next, the Example of this invention is shown.
