Problems solved by technology

[0004] Although the degree of reinforcement of fillers in rubber is particularly important and is an important basis for distinguishing good or bad fillers, there is no general test method for the degree of reinforcement of fillers in the rubber industry, and a unified and convincing measurement method is lacking. All are characterized by the physical strength or hardness of the rubber compound. This method is cumbersome to operate, with many influencing factors and large errors in test results.

Abstract

The invention relates to the technical field of tire production, in particular to a method for detecting the reinforcing degree of filler in rubber and application of the method. According to the method, the reinforcing degree of the filler in the rubber is determined by measuring the swelling index variation amplitude of different filler parts under the same formula system. The detection method is high in reproducibility and accurate in judgment.

Description

technical field [0001] The invention relates to the technical field of tire production, in particular to a method for detecting the reinforcing degree of filler in rubber and its application. Background technique [0002] Rubber is a highly elastic polymer material, which is the basic material for the manufacture of rubber products. There are many types of rubber, commonly used include natural rubber, polyisoprene rubber, polybutadiene rubber, styrene-butadiene copolymer rubber, etc., in addition to natural rubber and other self-reinforcing rubber with strain crystallization ability, Most of the rubber is non-self-reinforcing rubber, and non-self-reinforcing rubber has no practical strength before reinforcement modification. [0003] Reinforcement refers to the effect of significantly improving the tensile strength, tear strength and wear resistance of rubber at the same time. The main reinforcing materials used in the rubber industry are carbon black and white carbon black...
