Problems solved by technology

PVC has excellent chemical properties such as flame retardancy, insulation and wear resistance, and is widely used in building materials, light industry, agriculture and other fields, especially in the field of shoemaking. Due to its low price and excellent performance, PVC materials are gradually replacing Other polymer materials, but their heat resistance is poor, easy to decompose under high temperature conditions
[0003] Chinese patent (CN201210115846.0) discloses a heat-resistant PVC profile, which synthesizes ternary copolymerization in the presence of an initiator by adding thermosetting phenolic resin, styrene, methyl methacrylate, and N-phenyl maleamide. As a heat-resistant modifier, although it can improve the heat-resistant performance of PVC, the plasticity of the modified PVC is poor, the loss of mechanical properties is large, and the conditions are difficult to control in the process of synthesizing the terpolymer

Description

Technical field: [0001] The invention relates to the field of plastic processing, in particular to a heat-resistant PVC shoe material. Background technique: [0002] Polyvinyl chloride (PVC) is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. It is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator, which is a homopolymer of vinyl chloride. Polyvinyl chloride is one of the most produced plastic products in the world, and it is cheap and widely used. PVC has excellent chemical properties such as flame retardancy, insulation, and wear resistance, and is widely used in building materials, light industry, agriculture and other fields, especially in the field of shoemaking. Due to its low price and excellent performance, PVC materials are gradually replacing Other polymer materials, but its heat resistance is poor, and it is easy to decompose under high temperature conditions.
