Snowfield tricycle tread rubber and preparation process thereof

Abstract

The invention discloses snowfield tricycle tread rubber and a preparation process thereof, and relates to the technical field of tread rubber. Comprising the following raw materials in parts by weight: 50 to 55 parts of natural rubber, 25 to 30 parts of solution polymerized styrene-butadiene, 23 to 28 parts of butadiene rubber, 57 to 63 parts of carbon black, 12 to 18 parts of high-dispersion white carbon black, 3 to 5 parts of a silane coupling agent SI69, 17 to 23 parts of aromatic oil, 4 to 6 parts of zinc oxide, 0.75 to 1.25 parts of stearic acid SA, 1.5 to 2.5 parts of an anti-aging agent 4020, 0.75 to 1.25 parts of an anti-aging agent RD, 0.75 to 1.25 parts of an anti-aging agent DTPD3100, 1.5 to 2.5 parts of protective wax, 1.5 to 2.5 parts of a white carbon black dispersing agent and 0.5 to 0.8 part of an accelerant. 1.5 to 2 parts of sulfur; and 0.1 to 0.3 part of scorch retarder CTP. According to the snowfield tricycle tread rubber and the preparation process thereof, the prepared tread rubber has a relatively good anti-skid effect under the action of the combination of the solution polymerized styrene-butadiene rubber SSBR2438 and the high-dispersity white carbon black 7000 GR and the silane coupling agent, and in the preparation process, the vulcanization efficiency is improved due to the addition of the sulfur and the accelerant.

Description

technical field [0001] The invention relates to the technical field of tread rubber, in particular to a snow tricycle tread rubber and a preparation process thereof. Background technique [0002] Car tires are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they also require high wear resistance and flex resistance, and Low rolling resistance and heat generation. The tread is the only part of the car that is in direct contact with the road surface. Therefore, it is closely related to the safety, comfort and energy saving of the car during driving. The main function of the tread is Prevent the carcass from mechanical damage, transmit vehicle traction and braking force, and buffer the impact of the tire during driving. Therefore, the tread is also required to have good wear resistance, puncture resistance, goo...

AI Technical Summary

Problems solved by technology

[0003] During the use of the tricycle tread rubber in the prior art, a large amount of heat will be generated during the processing of the tire rubber material. When the tread is extruded, the phenomenon of cooked rubber is prone to occur, causing a serious decline in the performance of the tread rubber material. After vulcanized tires are used due to high heat generation, early cracking of the tread, delamination of the tread, etc., reduce the service life and safety of the tire. For this reason, we propose a snow tricycle tread rubber and its Preparation process to solve the above problems
