AI Technical Summary

Problems solved by technology

Commonly used reinforcing agents are mostly various carbon black, silica and inorganic materials. The addition of dry-mixed silica improves the physical properties and wear resistance of the tire, but it also makes the rubber Rolling resistance and heat generation increase and the Mooney viscosity is too high, the process fails, which increases the fuel consumption of the vehicle and reduces the service life of the tire

Abstract

The invention provides a whitening softening agent. The whitening softening agent comprises raw materials with the following content: 75-85% of a monomer silicide, 3-5% of a surfactant, 4-6% of a polyvinyl chloride (PVC) softening agent, 6.5-10.5% of a PVC toughening softening and strengthening agent, and 1.5-3.5% of a rubber softening agent. The whitening softening agent provided by the inventionis a green environment-friendly novel material, and accords with the national requirement. The requirement of improving the Mooney viscosity of mixed rubber by domestic tire factories is urgent, so that the utilization and application of the technology provided by the invention is of great significance.

Description

technical field [0001] The invention relates to a polymer material, in particular to a white softener and its preparation process and application. Background technique [0002] The traditional preparation method of rubber compound for tires and other rubber products is to add a large amount of reinforcing agent such as white carbon black, various performance compounding agents, and process coordination to the rubber compound in the form of dry mixing after natural rubber is masticated. agent. Commonly used reinforcing agents are mostly various carbon black, silica and inorganic materials. The addition of dry-mixed silica improves the physical properties and wear resistance of the tire, but it also makes the rubber Rolling resistance and heat generation increase, Mooney viscosity is too high, and the process fails, which increases the fuel consumption of the vehicle and reduces the service life of the tire. [0003] More and more stringent implementation rules and regulatio...
