Abstract

The invention provides an epichloro-hydrin rubber and polyvinyl chloride blending-type thermoplastic elastomer inner tube material and a preparation method thereof. The inner tube material is prepared by the following steps of: mixing 50-60 parts by weight of polyvinyl chloride to the temperature of 95 / 105 DEG C through a high-speed mixing blender; adding 50-60 parts of plasticizing agent dioctyl-phthalate (DOP) step by step; adding polyvinyl chloride added with the plasticizing agent DOP and 40-50 parts of homopolymerization epichloro-hydrin rubber to an internal mixer of 170 / 180 DEG C to be blended; and then, adding 0.8-1.0 part of calcium stearate, 0.2-0.25 part of antimony mercaptide, 2-4 parts of accelerator NA-22, 3-7 parts of lead tetroxide, 10-30 parts of N660 carbon black, 10-30 parts of calcium carbonate, 0.5-0.8 part of anti-aging agent MB, 8-15 parts of light magnesium oxide and 6-8 parts of processing agent acrylic copolymer (ACR) to continuously blend. Discharging can be carried out after an amperemeter of the internal mixer tends to be flat, and the discharged materials are uniformly mixed and put for one or two days at room temperature. By utilizing the material, energy resources are saved, the production rate is increased, material consumption in a production process is reduced, and the production cost is greatly lowered.

Description

technical field [0001] The invention relates to an inner tube material, in particular to a thermoplastic elastomer bicycle inner tube material blended with epichloride rubber and polyvinyl chloride and a preparation method thereof. Background technique [0002] Thermoplastic elastomer is a polymer material that shows high elasticity of rubber at room temperature and can be plasticized at high temperature. Its products not only have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, but also have the characteristics of more convenient and wide processing methods of ordinary plastics. Thermoplastic elastomer, also called thermoplastic rubber, is formed by blending rubber and plastic. Specifically, rubber and the vulcanizing agent added at the same time are dynamically vulcanized under the dual effects of high temperature and high shear rate, and are fully sheared into extremely small particles at the ...
