Problems solved by technology

For the synthesis of polyvinyl chloride and other materials, there are fewer products with high corrosion resistance, and some of the plates have poor corrosion resistance, resulting in a reduction in the life of the plates during use.
The unique performance of SMC composite materials solves the disadvantages of aging, corrosion, poor insulation, poor cold resistance, poor flame retardancy, and short life of wooden, steel, and plastic products.

Abstract

The invention discloses a high-corrosion-resistance plate material and a processing method thereof. The high-corrosion-resistance plate material comprises a PVC (polyvinyl chloride) base plate, wherein an upper layer and a lower layer of the PVC base plate are covered with SMC (sheet molding compound) co-extrusion layers; the PVC base plate is mainly made from PVC and whiskers. According to the high-corrosion-resistance plate material, any adhesive substances are not adopted, and any harmful substances are not discharged. By adding the whiskers into a raw material, namely the PVC, the weather resistance and strength of the material can be improved. An SMC has good physical performance and is co-extruded to cover the base plate, so that the corrosion resistance and abrasion resistance of the plate material are improved.

Description

technical field [0001] The invention relates to a plate with high corrosion resistance, in particular to a plate with high corrosion resistance and a processing method thereof. Background technique [0002] At present, most of the weather-resistant plate products are produced by using polyvinyl chloride and other materials to synthesize. For the synthesis of polyvinyl chloride and other materials, there are few products with high corrosion resistance plates, and some plates have poor corrosion resistance, resulting in a reduction in the life of the plates during use. The unique performance of SMC composite materials solves the disadvantages of aging, corrosion, poor insulation, poor cold resistance, poor flame retardancy, and short life of wooden, steel, and plastic products. In the application process, it has the characteristics of absolute sealing and waterproof performance, anti-corrosion performance, beautiful appearance and long service life.
