Anti-corrosion decorative panel

Abstract

The invention discloses a corrosion-resistant decorative panel, which comprises a paint layer, a filling layer and a reinforcing layer, the thickness of the reinforcing layer is 20% to 40% of the corrosion-resistant decorative panel, and the thickness of the filling layer is 20% of that of the corrosion-resistant decorative panel. 50% to 80% of that; the reinforcing layer is a metal plate; the filling layer is a wood-plastic material, and the coating layer is an anti-corrosion paint. The product obtained by the invention can give full play to the high-strength characteristics of engineering plastic nylon, and the mechanical properties such as bending strength and bending elastic modulus are significantly improved. At the same time, the building wallboard of the present invention is used in combination with a thinner metal layer and a wood-plastic material layer, and has higher strength. At the same time, self-made paint is used, which can effectively prevent corrosion and insects.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to a corrosion-resistant decorative panel. Background technique [0002] With the increasingly serious environmental damage, log resources, as a non-renewable resource, have become more and more precious and scarce. In order to reduce people's dependence on log resources, the waste furniture wood and branches and branches are crushed and removed, and then heat-milled into fiber materials, and then the mixture is paved and hot-pressed after being mixed with an adhesive. This production method is adopted. Man-made fiber composite boards manufactured can reduce people's dependence on log resources to a certain extent and help improve the ecological environment. During use, it is easy to cause moths and cause damage to the composite board. [0003] In order to prevent moths, existing scholars have carried out corresponding research. For example, the patent "Safe Mothproofing A...

Problems solved by technology

Traditional wood-plastic composite materials use PVC, PE, and PP three general-purpose plastics as base materials, and their strength is not high, so they can only be used in places with low performance requirements. Generally, the bending strength does not exceed 50MPa, so they cannot be used as structural materials.

[0005] Many researchers have studied the use of nylon as a base material to produce wood-plastic composites, but because the melting point of nylon generally exceeds 220°C, and wood fibers contain high-temperature-resistant cellulose (the thermal degradation initiation temperature exceeds 250°C), there are also Contains hemicellulose and lignin whose thermal degradation initiation temperature is lower than 200°C, the processing temperature does not match, and the degradation is serious. Therefore, nylon and cellulose or nanocellulose are generally mixed for extrusion or injection molding, and the production cost is high, and Preparation of cellulose or nanocellulose requires more energy and pollutes the environment
