Problems solved by technology

[0002] At present, the walls, roofs and some temporary buildings of factories and other buildings are usually built with plates such as color steel plates. In order to obtain better corrosion resistance and prolong their service life, anti-rust paint is usually sprayed on the surface of plates such as color steel plates , but in actual application, it is found that the method of spraying anti-rust paint cannot meet the waterproof, anti-rust and fire-proof performance requirements required by customers

Abstract

The invention relates to a weather-resistant composite board and a preparation method thereof. The weather-resistant composite board comprises a board layer (1), and a weather-resistant layer (2) is compounded on the board layer (1); an adhesive layer (3) is adhered between the board layer (1) and the weather-resistant layer (2); and a frosted layer is arranged on the upper surface of the board layer (1) in a polishing manner, the adhesive layer (3) is compounded on the frosted layer, and the weather-resistant layer (2) is an ethylene propylene diene monomer layer, a high polymer material layer or a silicon rubber layer. According to the weather-resistant composite board and the preparation method thereof, the weather-resistant composite board has excellent waterproof, antirust and fireproof performance.

Description

technical field [0001] The invention relates to a weather-resistant composite board and a preparation method thereof, belonging to the technical field of composite boards. Background technique [0002] At present, the walls, roofs and some temporary buildings of factories and other buildings are usually built with plates such as color steel plates. In order to obtain better corrosion resistance and prolong their service life, anti-rust paint is usually sprayed on the surface of plates such as color steel plates , but in actual application, it is found that the method of spraying anti-rust paint cannot meet the waterproof, anti-rust and fire-proof performance requirements required by customers. Therefore, there is an urgent need for a plate structure that can solve the above problems; and in the rubber field to which the company belongs, in addition to the existing weather-resistant silicone rubber, the newly launched EPDM rubber in recent years is made of ethylene, propylene...
