Abstract

The invention relates to a composite PVC (Polyvinyl Chloride) board and belongs to the technical field of plastics. The composite PVC board comprises a first weather-proof PVC composite layer, a firstbonding layer, a PVC main body layer, a second bonding layer, a PVC composite buffer layer and a second weather-proof PVC composite layer sequentially stacked. Compared with the prior art, the composite PVC board has the beneficial effects that: multiple layers of composite structures are adopted, the PVC board is formed by compositing PVC materials having different functions, so that the composite PVC board is excellent in stability, ageing resistance and shock resistance, and meets the requirements of different use environment.

Description

Technical field [0001] The invention relates to the technical field of plastics, in particular to a composite PVC board. Background technique [0002] PVC material is polyvinyl chloride. It is one of the largest plastic products in the world. It is cheap and widely used. Polyvinyl chloride resin is white or light yellow powder. It cannot be used alone and must be modified. PVC is a white powder with an amorphous structure with a small degree of branching and poor stability to light and heat. Different additives can be added according to different purposes, and PVC plastics can present different physical and mechanical properties. The existing plastic boards made of PVC materials have single performance. How to design a composite PVC board is an urgent problem in the industry. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings of the prior art and provide a composite PVC board. [0004] To achieve the above objective, the ...
