Abstract

A weather-proof composite board is disclosed. A wood-plastic base plate serves as a basic board, a weather-proof layer is arranged outside the wood-plastic base plate, the wood-plastic base plate is sealed through the weather-proof layer, the wood-plastic base plate is prevented from making contact with the outside, and therefore aging of the internal wood-plastic base plate is avoided, the weather-proof performance of the composite board is improved, and the weather-proof layer is not affected by the outside temperature. Meanwhile, a steel structure layer is arranged on the outer side of the weather-proof layer, and the rigidity of the composite board is improved through the steel structure layer; a sealing layer is arranged outside the steel structure layer, so that the sealing performance of the composite board is further guaranteed; a fireproof layer is arranged outside the sealing layer so that fireproof performance of the composite board is effectively improved, and the sealing layer is effectively protected from being damaged, the weather-proof structure of the composite board is not damaged, and the problems that an existing wood-plastic composite board is prone to corrosion and deformation after being used for a long time, and the weather-proof performance is poor are effectively solved.

Description

Technical field [0001] The present invention relates to the field of composite sheets, and more particularly to a weathering composite sheet. Background technique [0002] The composite sheet refers to a sheet formed from a variety of materials. According to the material, there are three common composite sheets, and the glass steel composite sheet, wood-plastic composite sheet, and metal composite sheet. The above composites are characterized, but they have more or less defects: the glass steel composite sheet is high temperature resistance, the anti-aging performance is poor, and the metal composite sheet processing process is complex, the cost is high, and the material is also heavy. In contrast, the utility of wood-plastic composite sheets is high, and the existing wood-plastic composite sheet has long been used for long-term use, and the weather resistance is poor. Inventive content [0003] The primary object of the present invention is to provide a problem of weather resis...
