Simulated aluminum sheet wallboard coated with ultraviolet-resistant coating and preparation method thereof

Abstract

The invention relates to a simulated aluminum sheet wallboard coated with an ultraviolet-resistant coating and a preparation method thereof. The simulated aluminum sheet wallboard comprises a simulated aluminum sheet base layer (1), a simulated aluminum sheet fluorocarbon lacquer coating (2) and an ultraviolet-resistant coating (3), wherein the external surface of the simulated aluminum sheet base layer (1) comprises the simulated aluminum sheet fluorocarbon lacquer coating (2); and the ultraviolet-resistant coating (3) is sprayed on the simulated aluminum sheet fluorocarbon lacquer coating (2). The preparation method comprises the following steps: mixing coal gangue fiber particles, high-polymer fireproof modified material, silicon aluminum clinker and stearic acid, drying at 150 DEG C, stirring for 20 minutes, extruding into a mold with simulated aluminum sheet grains, molding, spraying the fluorocarbon lacquer on the external veneer of the product, drying, and spraying the ultraviolet-resistant paint. The preparation method is simple to operate and simplifies the procedure; and the simulated aluminum sheet wallboard has the advantages of beautiful appearance, environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the field of building boards, in particular to an aluminum-like wall board coated with an anti-ultraviolet coating and a preparation method thereof. Background technique [0002] With the continuous development of building decoration, people have higher and higher requirements for decoration, especially in the selection of materials, which not only require reasonable price, economical and practical, but also elegant appearance and environmental protection requirements. [0003] Now there are a variety of imitation aluminum plate walls for people to choose from in the market to meet consumers with different needs. Because these imitation aluminum plate walls are generally made of block building materials for masonry, and then thermal insulation and plastering are added on the outside. Ash, and finally artificially sprayed on the construction site to form an imitation aluminum plate wall. The imitation aluminum plate wall produc...

Problems solved by technology

[0003] Now there are a variety of imitation aluminum plate walls for people to choose from in the market to meet consumers with different needs. Because these imitation aluminum plate walls are generally made of block building materials for masonry, and then heat insulation and plastering are added on the outside. Ash, and finally artificially sprayed on the construction site to form an imitation aluminum plate wall. The imitation aluminum plate wall produced in this way is greatly affected by the change of ambient temperature and cannot resist the erosion of external ultraviolet rays and wind and rain well. The flatness will change, and the effect of its imitation aluminum plate will be weakened, the strength is low, and the anti-seismic effect is poor, and the preparation process of these imitation aluminum plate walls is complicated, the precision is poor, and the cost is high, which is not convenient for wide-scale promotion and use.
