Problems solved by technology

However, due to the shortcomings of PVC's poor light and thermal stability, the PVC tarpaulin is prone to aging problems during use, especially in hot weather, which affects the strength of the PVC tarpaulin.
Although the existing PVC tarpaulin formula will add light and heat stabilizers to delay this aging phenomenon, but the amount of light and heat stabilizers added is limited, so there is no lasting resistance to the aging of PVC tarpaulins effect, resulting in the strength of the tarpaulin being greatly weakened

Abstract

The invention discloses high-toughness ageing-resistant PVC covering cloth. The high-toughness ageing-resistant PVC covering cloth is formed by coating both sides of woven fabric with a PVC priming coat and then coating the PVC priming coat with a PVC surface film. The raw material formula of the PVC coating comprises the following ingredients (by weight): 80 parts of PVC paste resin, 10-30 parts of chlorinated polyethylene, 40-85 parts of dicapryl phthalate, 1-8 parts of anatase titanium dioxide, 1-35 parts of carapace milled powder, 3-6 parts of a stabilizing agent and 1-6 parts of an adhesive. The raw material formula of the PVC surface film comprises the following ingredients (by weight): 80 parts of PVC paste resin, 10-30 parts of chlorinated polyethylene, 40-85 parts of dicapryl phthalate, 1-8 parts of anatase titanium dioxide, 0.5-5 parts of rubber powder, 3-6 parts of a stabilizing agent and 1-6 parts of an adhesive. The high-toughness ageing-resistant PVC covering cloth has good heat stability, high strength and high toughness and has good surface characteristic.

Description

technical field [0001] The invention relates to a high-tough and aging-resistant PVC tarpaulin. Background technique [0002] The PVC tarpaulin is a double-sided coated PVC paste resin for the base fabric. Compared with ordinary PE tarpaulins, PVC tarpaulins are far superior to PP and PE tents in rain resistance, and are widely used in tents, automobiles, trains, storage and other fields. In addition, PVC is low in cost, rich in sources, non-toxic, and is a membrane material worth promoting. However, due to the shortcomings of PVC's poor light and thermal stability, PVC tarpaulins are prone to aging problems during use, especially in hot weather, which affects the strength of PVC tarpaulins. Although the existing PVC tarpaulin formula will add light and heat stabilizers to delay this aging phenomenon, but the amount of light and heat stabilizers added is limited, so there is no lasting resistance to the aging of PVC tarpaulins effect, resulting in the strength of the tarp...
