Waterproof composite building material for building

Abstract

The invention discloses a waterproof composite building material for a building. The waterproof composite building material comprises a protection layer, a waterproof layer, a reinforcing rib layer, an FRP base material layer and a thermal insulating layer; the protection layer is arranged on the outermost side of the composite building material, the waterproof layer, the reinforcing rib layer, the FRP base material layer and the thermal insulating layer are sequentially arranged under the protection layer in a laminated mode, and an adhesive layer is further arranged between the waterproof layer and the reinforcing rib layer. According to the waterproof composite building material for the building, the waterproof layer is arranged and can achieve the waterproof effect, and the overall waterproof property of the waterproof composite building material is guaranteed; by means of arrangement of additionally arranging the reinforcing rib layer, the whole waterproof composite building material has a good anti-impact property and high bending strength and tensile strength, the strength of the waterproof building material can be effectively improved, and the service life of the waterproof building material can be guaranteed; meanwhile, due to the fact that the thermal insulating layer is arranged, a good thermal insulating effect can be achieved, the outer surface of the protection layer is coated with a nano-titanium dioxide coating, the waterproof composite building material can have a self-cleaning capacity, and meanwhile the light transmittance is increased.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof composite building material for construction. Background technique [0002] Building materials will withstand wind, sun, rain, abrasion, corrosion, etc. for a long time, and their performance will gradually change. The reasonable selection of building materials is essential. First, it should be safe and durable. The amount of building materials is large, which directly affects the engineering The cost of building materials usually accounts for more than half of the total project cost. Therefore, when considering technical performance, economic efficiency must be taken into account. Moreover, some special buildings must use waterproof building materials. The selection of waterproof building materials is very important. [0003] Daylighting panels are widely used in the construction field, and the benefits to people are obvious. FRP daylighting board, commonly kno...

AI Technical Summary

Problems solved by technology

Due to the lack of strength of the daylighting panels in the prior art, for some workshops with large spans and large purlin spacing, which require better wind and snow resistance, the daylighting panels of the prior art often affect the use due to insufficient product strength. life

Or it cannot be well insulated, and because the lighting board is often installed on a large factory building, it cannot be cleaned for a long time, and the lighting rate drops

Bring great inconvenience to people's life

And there is no waterproof effect, it is easy to leak in rainy weather, causing inconvenience to users
