Abstract

The invention discloses a preparation method of a high-strength and high-property rubber material. The preparation method comprises the following steps of providing straws, and performing nanocrystallization treatment on the straws; mixing the straws after nanocrystallization, aluminum silicate fibers and carbon black, so as to obtain a first mixture; performing ball milling on the first mixture,so as to obtain a first solid additive; mixing lanthanum glutamate (DAGLa), a vulcanizing agent, hydroxyl silicone oil and a processing additive, so as to obtain a second mixture; stirring the secondmixture at high speed, so as to obtain a second additive; providing methyl phenyl vinyl silicone rubber; mixing the methyl phenyl vinyl silicone rubber at multiple stages; adding the second additive into a mixing adhesive in the second stage of mixing, and performing the third stage of mixing, so as to obtain semi-finished silicon rubber; treating the semi-finished silicon rubber at medium temperature; performing the first stage of vulcanizing on the semi-finished silicon rubber after medium-temperature treatment, so as to obtain the semi-vulcanized rubber; performing the second stage of vulcanizing on the semi-vulcanized rubber.

Description

technical field [0001] The invention belongs to the technical field of advanced rubber materials, and relates to a preparation method of high-strength and high-performance rubber materials. Background technique [0002] Filling the polymer matrix with tiny particles as a reinforcing agent to prepare biodegradable composite materials with excellent performance has become a hot spot in the field of polymer materials in recent years. Initially, the fillers used were mainly inorganic minerals, such as carbon black, kaolinite, silicate and clay. However, most of these fillers are harmful to the environment and even human health. In the middle and late twentieth century, scholars in the northern part of the United States used starch instead of carbon black to study the change in the reinforcing effect of rubber after adding cross-linked starch xanthate to rubber. The results showed that starch xanthate and intermediate carbon black The reinforcing effect produced is the same. T...
