The utility model relates to an environment-friendly and safe glass fiber reinforced board, especially a kind of roof erection for outdoor buildings and factory buildings, which improves the structural strength and has the function of a safety layer net, and prevents the whitening of the glass fiber after long-term use. Environmental problems such as clogged sinks and ditches caused by scattering, polluted air, etc., and at the same time have anti-ultraviolet effect, can resist sun and rain, acid and alkali attack and corrosion resistance, and can prolong the service life of the glass fiber board.

Background technique

Glass fiber board is made of glass fiber impregnated with resin and then hardened. It is a kind of composite material. It has better strength characteristics than plastic materials, and it has good light transmission. It can be used as a building lighting board. In the past, the glass fiber lighting board is made of several layers of glass fiber cut mat impregnated with resin and then hardened by sandwich method. The resin layer is located at the outermost layer of the board body and is in contact with the outside world. The resin layer will be corroded and peeled off due to weather factors such as sun and rain, which will cause the inner glass fiber layer to be exposed, whitened and damaged. Therefore, due to poor weather resistance, the glass fiber will scatter and block the sink and ditch. , air pollution and other environmental issues. At the same time, due to the limitation of the mechanical strength of the glass fiber strand mat and the decrease of the strength of the board after aging, the public safety problem of maintenance workers falling from the roof lighting board is often criticized by people, and the industry needs to work hard to overcome it and improve it.

Utility model content

The main purpose of the utility model is to provide an environmentally safe glass fiber reinforced board. Through this design, the environmental protection problems caused by the whitening and damage of the existing glass fiber boards, and the problems of endangering the safety of personnel caused by the decrease in strength are improved.

In order to achieve the aforementioned purpose, the environmentally safe glass fiber reinforced board designed by the utility model includes:

A substrate, which includes several resin layers and several glass fiber layers, and the resin layers and glass fiber layers are alternately stacked; and

A reinforcement unit, which is arranged on the outer surface of the base, the reinforcement unit includes a glass fiber cloth layer and a reinforced shell resin layer, the glass fiber cloth layer is located on the outer surface of the base, and the reinforced shell resin A layer is covered on the outer surface of the glass fiber cloth layer.

According to the above, the utility model utilizes the reinforced unit composed of the glass fiber cloth layer and the reinforced plastic shell resin to form a barrier protection against the acid and alkali attack of external ultraviolet rays and weather rainwater, thereby preventing the glass fiber layer in the base from being exposed. damaged. Therefore, this environmentally friendly and safe glass fiber reinforced board has better defense and weather resistance, which can achieve the effect of prolonging the service life of the board, and at the same time prevent problems such as clogging sinks and ditches and polluting the air caused by glass fiber scattering, so it is more Environmentally friendly, the fiber structure in the glass fiber cloth layer of the reinforced unit is uniform and firm, and does not disperse and break, so the environmentally safe glass fiber reinforced board has a high fiber content, good tensile strength and impact resistance, and the reinforced unit The setting is like adding a layer of safety net, and can reduce the public safety problems of future maintenance.

Detailed ways

Please refer to FIGS. 1 and 2 , which are a preferred embodiment of an environmentally safe glass fiber reinforced board 1 of the present invention, which includes a base 10 and a reinforcing unit 20 .

The substrate 10 includes several resin layers 11 and several glass fiber layers 12, and these resin layers 11 and glass fiber layers 12 are stacked alternately as shown in Figure 1, wherein these glass fiber layers 12 can be existing glass fiber cut strands It is a layered structure composed of felt or glass fiber cloth, and can be properly configured according to the needs in order to achieve the predetermined effect.

The reinforcing unit 20 includes a glass fiber cloth layer 21 and a reinforced plastic shell resin 22, the glass fiber cloth layer 21 is located on the outer surface of the base 10, and the reinforced plastic shell resin layer 22 covers the glass fiber cloth layer 21 The outer side is the uppermost, so that the reinforcement unit 20 is located at the sunny side of the base 10, wherein the glass fiber cloth layer 21 is composed of long glass fiber yarns criss-crossed with warp and weft threads to form a uniform and strong woven fabric, It can effectively block the glass fiber in the substrate from being exposed, and the glass fiber cloth layer 21 has excellent tensile strength and impact resistance, and the reinforced plastic shell resin layer 22 is made of reinforced plastic shell resin, and the reinforced rubber The shell resin contains anti-ultraviolet additives, acid and alkali-resistant resin and high-performance unsaturated polyester resin, so that the strengthening unit 20 has anti-ultraviolet effect, and can resist the erosion of external acid and alkali liquid or water, so as to resist and protect the base purpose.

Among the above, the glass fiber slit mat is a mat formed by combining several cut glass fiber strands with a powdery adhesive, and these glass fiber strands are not oriented and uniformly distributed, and in the present invention In a preferred embodiment, the weight range of the glass fiber cut mat used is 220-900 g/m2, and the weight range of the glass fiber cloth used in the present invention is 30-880 g/m2.

Referring to Fig. 3 and 4, it is the plate shape formed by stacking and combining molds or other molding methods of the utility model. It forms several arched convex parts, and forms turning shoulders on both sides of the convex parts. , so that the overall structure has more compressive and bending strength.

To sum up, the environmental protection and safety glass fiber reinforced board 1 of the utility model has the following characteristics:

1. Good fire resistance and not easy to deform: the fiber structure of the glass fiber cloth layer 21 of the reinforcement unit 20 is uniform and firm, and does not disperse and break. It is matched with the glass fiber layer 12 in the base 10, so the environment-friendly and safe glass fiber reinforced board 1 The fiber content is higher, and the flame resistance and fire protection level are relatively improved. At the same time, the coefficient of thermal expansion is lower than that of traditional glass fiber boards. Therefore, when it is used with steel plates for outdoor buildings and factory roofs, it is less likely to cause deformation and rain leakage problems of glass fiber boards.
