Abstract

The invention relates to the field of polyvinyl chloride, particularly to a scratch-resistant PVC film and a preparation method thereof. The PVC film is prepared from the following raw materials in parts by weight: 100 parts of PVC powder, 2-8 parts of a scratch-resistant modifier, 0.2-1.0 part of a slipping processing aid, 5-15 parts of a plasticizer, 0.8-2 part of a wear-resistant agent, 2-4 parts of a stabilizer, 2-10 parts of an impact modifier, 0.1-0.5 part of an external lubricant, 0.1-0.5 part of a lubricant and 0.8-2.5 parts of an aid. According to the invention, by adding the wear-resistant agent, the scratch-resistant effect is achieved, the precipitation of the rubber flower roller is reduced, and the processing technology difficulty caused by adding the wear-resistant agent inthe prior art is overcome.

Description

technical field [0001] The invention relates to the field of polyvinyl chloride, in particular to a scratch-resistant PVC film and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the most produced plastic products in the world and is widely used due to its cheap price. Like other thermoplastics, PVC is made by extrusion, blow molding, calendering, molding, rotational molding, slush molding, coating, dipping, and foaming. Adding an appropriate amount of plasticizer to polyvinyl chloride can make a variety of hard, soft and transparent products. Among them, hard polyvinyl chloride products can replace wood, glass, and steel, and are the most widely used, accounting for about 60% of polyvinyl chloride products. It is widely used due to its light weight, high mechanical strength, good insulation performance and excellent comprehensive properties such as chemical resistance. However, due to the different requirements for the speci...
