Production process of anti-skid snow tyre

Abstract

The invention discloses an anti-skid snow tyre. The anti-skid snow tyre is composed of, by weight percentage, 20-30% of natural rubber, 15-20% of butadiene rubber, 8-12% of butadiene styrene rubber, 10-15% of carbon black, 10-30% of white carbon black, 10-20% of calcium carbonate, 1-2% of anti-ageing agent 4020, 0.2-0.6% of promoter, 1-2% of octyl-phenolic resin, 0.6-1% of sulfur, 0.5-1% of vulcanizing activator, 0.8-1.2% of nanogel, 0.4-0.6% of bamboo charcoal powder and 0.4-0.6% of shell activated carbon. The invention also discloses a preparation process of the anti-skid snow tyre. The preparation method of the anti-skid snow tyre comprises S1, mixing, S2, extruding, S3, fixed-length cutting and S4, vulcanization. By means of the three-dimensional net feature of the nanogel and by adding the bamboo charcoal powder and the shell activated carbon, the anti-skid snow tyre can increase the wearing resistance and the adhering strength on the road surface; by maintaining pressure with nitrogen during vulcanization, the vulcanization pressure can be increased, and the overall uniformity of the anti-skid snow tyre can be improved.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a preparation process of snow-resistant skid tires. Background technique [0002] The driving of the vehicle depends on the mutual adhesion between the tire and the ground. The road surface is in good condition and the adhesion factor is large, so the performance requirements of the tire are not high. However, in cold areas, there are often rainy and snowy weather in winter. It is inconvenient, especially for vehicles driving on ice and snow roads. Since the tires of general vehicles are mostly designed for dry ground, the friction coefficient between them and the ice and snow roads is small. In an emergency, the vehicle cannot brake effectively, causing traffic accidents and causing loss of life and property. [0003] At present, the main anti-skid technologies for tires are anti-skid chains and anti-skid studs, but these anti-skid measures have disadvantages such as complicated ...
