Abstract

The invention discloses an anti-corrosion wear-resisting and ageing-resistant modified polyvinyl chloride (PVC) plastic composition, and relates to the technical field of plastics. The anti-corrosion wear-resisting and ageing-resistant modified PVC plastic composition comprises the following components by weight percent: 90-110g of polyvinyl chloride resin, 25-30g of dioctyl phthalate, 20-25g of dibutyl phthalate, 0.5-2g of barium stearate, 0.1-0.5g of paraffin, 0.5-1g of cadmium stearate, 0.1-0.5g of hindered amine optical stabilizer, 65-80g of ATO nano powder, 8-10g of modifier, and 8-10g of composite disperse modifier. By adopting the anti-corrosion wear-resisting and ageing-resistant modified PVC composition, the PVC has excellent performances such as corrosion resistance and abrasive resistance, can endure relatively high pressure, is not easy to form a dart, and can resist certain negative pressure.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a corrosion-resistant, wear-resistant and anti-aging modified PVC plastic composition. Background technique [0002] PVC material is polyvinyl chloride, which is one of the largest plastic products in the world. It is cheap and widely used. The polyvinyl chloride resin is white or light yellow powder. Different additives can be added according to different uses, and PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products. With the development of social urbanization, technology, and humanization, and the rapid development of the PVC industry, PVC materials are getting closer to people's lives, followed by an increase in the use of PVC, and the heat resistance of most PVC materials is not good. Well, flammable. And when burning, it is ...
