Abstract

The invention provides a bending-resistant air-permeable polyvinyl chloride vamp material. The bending-resistant air-permeable polyvinyl chloride vamp material is prepared from the following components in parts by weight: 54-64 parts of polyvinyl chloride, 11-16 parts of a plastifier, 3-4 parts of a stabilizing agent, 7-10 parts of a compatibilizer, 18-22 parts of a filling, 1-2 parts of a lubricant, 3-5 parts of an anti-wear agent, 4-5 parts of a blowing agent, 4-6 parts of an antibacterial agent, 5-6 parts of CPE, 8-10 parts of modified alpinia speciosa fibers, 2 parts of zinc oxide, and 3 parts of stearic acid. The invention further provides a preparation method of the bending-resistant air-permeable polyvinyl chloride vamp material. The polyvinyl chloride vamp material provided by the invention is high in bending resistance and good in air permeability.

Description

Technical field: [0001] The invention relates to a shoe upper material, in particular to a bending-resistant and breathable polyvinyl chloride shoe upper material and a preparation method thereof. Background technique: [0002] Polyvinyl chloride (PolyvinylChloride), referred to as PVC, is an important organic synthetic material in my country and belongs to the synthetic resin category of the three major synthetic materials (synthetic resin, synthetic fiber, and synthetic rubber). Polyvinyl chloride is formed by free radical polymerization of vinyl chloride monomer. The degree of polymerization n is generally in the range of 500 to 20,000. It is a non-toxic, odorless white powder. High chemical stability and good plasticity. Except for a few organic solvents, it can withstand any concentration of hydrochloric acid, sulfuric acid below 90%, nitric acid below 50% and caustic soda below 20% at room temperature, and is quite stable for salts; PVC has relatively high thermal sta...
