Problems solved by technology

Although the existing belts have excellent tensile strength, appropriate hardness, flexibility, elasticity, good buckling and high impact resistance, due to the high-speed operation of the belt, the surface of the pulley generates high temperature, thereby resisting aging Braiding machine belts tend to age on the surface and cause them to break

Abstract

The invention discloses an anti-aging knitting machine belt and a preparation method thereof. The preparation method comprises the following steps: 1) carrying out hydrothermal reaction on diatomite,vinyl triethoxy silane, aluminum salt, magnesium salt, zirconium salt, alkali and water, then filtering, and taking a filter cake, so that a hydrothermal product is obtained; 2) carrying out ball milling on the hydrothermal product, silicon nitride, boron nitride and dodecyl trimethyl ammonium chlorinate, so that an anti-aging auxiliary is obtained; 3) mixing isoprene rubber, tetraethylthiuram disulfide, zinc borate, vaseline, stearic acid and the anti-aging auxiliary, so that a knitting machine belt material is obtained; and 4) carrying out mixing and moulding on the knitting machine belt material, so that the anti-aging knitting machine belt is obtained. The anti-aging knitting machine belt disclosed by the invention has excellent anti-aging property, and the preparation method disclosedby the invention has the advantages of simple technology and available raw materials.

Description

technical field [0001] The invention relates to an anti-aging additive, in particular to an anti-aging braiding machine belt and a preparation method thereof. Background technique [0002] A weaving machine is a very common weaving machine. There are a large number of pulleys and belts in the knitting machine to drive the operation of the knitting machine. The existing belts are generally rubber belts, and the main raw materials can be natural rubber, polybutadiene rubber, styrene-butadiene rubber, ethylene propylene diene rubber, neoprene rubber, chlorosulfonated polyethylene rubber, nitrile butadiene rubber, etc. Rubber and hydrogenated nitrile rubber, etc. Although the existing belts have excellent tensile strength, appropriate hardness, flexibility, elasticity, good buckling and high impact resistance, due to the high-speed operation of the belt, the surface of the pulley generates high temperature, thereby resisting aging Braider belts tend to have an aging surface t...
