Description

Technical Field

[0001] The present invention relates to a weather-resistant composite board and a preparation method thereof, belonging to the technical field of composite boards. Background Art

[0002] At present, the walls and roofs of buildings such as factories and some temporary buildings are usually built with plates such as color steel plates. In order to obtain better corrosion resistance to extend their service life, anti-rust paint is usually sprayed on the surface of plates such as color steel plates. However, it is found in actual applications that the method of spraying anti-rust paint cannot meet the waterproof, anti-rust and fireproof performance requirements of customers. Therefore, there is an urgent need for a plate structure that can solve the above problems; in the rubber field to which the enterprise belongs, in addition to the existing weather-resistant silicone rubber, the ethylene propylene diene monomer (EPDM) newly launched in recent years is a copolymer composed of ethylene, propylene and a small amount of non-conjugated diene. Therefore, the main chain of EPDM is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chain. So, EPDM has excellent anti-ozone, heat resistance, weather resistance and other anti-aging properties; at the same time, the polymer materials in the polymer field also have extremely high weather resistance such as waterproof and anti-rust properties; thus, this patent considers compounding EPDM, silicone rubber and polymer materials with plates in the conventional construction field to form a new composite board structure to meet the weather resistance requirements such as waterproof, anti-rust and fireproof performance. Summary of the Invention

A circular cutting positioning groove is arranged on the wheel surface of the guide wheel. A cutting wheel mounting rod is installed parallel to the guide wheel mounting rod, and cutting wheels are installed at both ends of the cutting wheel mounting rod, and the circular cutting edges of the cutting wheels are embedded in the cutting positioning grooves of the guide wheels; Two through holes are arranged on the working surface of the cutting machine cabinet, and the two through holes are respectively located beside the two cutting wheels; the two sides of the board polished by the grinding mechanism are pressed tightly by the rubber pressing wheels, and the side material strips with residual edges are cut off through the cooperation of the guide wheels and the cutting wheels, and the side material strips fall into the inside of the cutting machine cabinet through the through holes;

[0017] The glue - applying and glue - spreading mechanism includes a glue - applying and turning roller and a glue - spreading and turning roller which are arranged vertically. The glue - spreading and turning roller is directly above the glue - applying and turning roller. The plate material cut by the edge - material cutting mechanism is introduced into the glue - applying and glue - spreading mechanism from the left. After being turned 90° upward by the glue - applying and turning roller, it is then turned 90° to the left by the glue - spreading and turning roller and conveyed.
