Inorganic nanoparticle modified PVC composite material craft shoe sole and preparation method thereof

Abstract

The invention relates to the field of composite plastic materials, in particular to an inorganic nanoparticle modified PVC composite material craft shoe sole and a preparation method thereof. The inorganic nanoparticle modified PVC composite material craft shoe sole comprises the following raw materials in parts by weight: 120-150 parts of PVC resin, 10-15 parts of composite modified nanoparticles, 8-12 parts of chlorinated polyethylene, 1-3 parts of calcium stearate, 4-8 parts of a plasticizer and 2-5 parts of a stabilizer. According to the inorganic nanoparticle modified PVC composite material process shoe sole disclosed by the invention, nano TiO2, nano ZnO and nano SiO2 are coated with a polymer to form composite modified nanoparticles taking nano TiO2, nano ZnO and nano SiO2 as an inner core, polybutyl acrylate as an outer core and polymethyl methacrylate as a shell, and the composite modified nanoparticles are then blended with a PVC matrix, such that the impact resistance and the tensile resistance of the PVC material are effectively improved, the softening temperature of the PVC material is increased, and the application range of the PVC material is expanded.

Description

Technical field [0001] The invention relates to the field of composite plastic materials, in particular to an inorganic nano particle modified PVC composite material craft shoe sole and a preparation method thereof. Background technique [0002] The structure of the sole is quite complicated. In a broad sense, it can include all the materials that make up the bottom such as the outsole, midsole, and heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should have wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to fit the shape of the foot, and not easy to change after setting. Heat insulation, easy to absorb moisture, etc., and at the same time, it must be matched with the midsole. When walking and changing feet, it has a braking effect to prevent slipping and easy to stop. There are many types of sole materials, which can be divided into two ...

Problems solved by technology

The TiO to be prepared in this invention 2 It is directly added to PVC resin for mixing, but the effect of dry treatment of nanoparticles in high-speed mixing equipment is not good. It is difficult to disperse in the matrix and easy to agglomerate, so it causes damage to the matrix resin and produces stress concentration. Under the action of external force, the agglomerated particles will slip each other, making the performance of the system worse
