Embodiment 1

[0030]A high damping and anti-aging rubber product is composed of three layers of different rubbers, such as outer layer rubber, middle layer rubber and inner layer rubber, wherein the outer layer rubber is composed of the following raw materials by weight: 60 parts of ethylene acrylate rubber, chlorine 40 parts of butadiene rubber, 30 parts of carbon black (reinforcing and filling system), 20 parts of white carbon black (reinforcing and filling system), 3 parts of paraffin oil (plasticizing system), 1 part of polyethylene wax (plasticizing system), anti-aging 1 part of agent RD, 2 parts of antioxidant 4010NA, 5 parts of zinc oxide (activation system), 4 parts of magnesium oxide (activation system), 1 part of stearic acid (activation system), 1 part of sulfur (vulcanization system), peroxide ( vulcanization system) 2 parts; the inner rubber layer is composed of the following raw materials by weight: 70 parts of butyl rubber, 30 parts of styrene-butadiene rubber, 30 parts of car...

Embodiment 2

[0040] In the rubber mixing process, an appropriate amount of masterbatch and adhesive systems such as resorcinol and hexamethoxymethyl melamine are added as needed. The masterbatch is an indispensable part of the preparation of composite rubber materials. The reinforcing and filling system in each layer of rubber formulation is included, and the reinforcing and filling system is wet-mixed with the natural rubber latex grafted with silica to obtain the masterbatch. like figure 1 As shown, the masterbatch preparation process is as follows:

[0041] The filler water slurry is obtained by mechanically stirring fillers such as silica and carbon black in water. The filler water slurry is mixed with the natural rubber latex grafted with silica and then coagulated and dehydrated to obtain a masterbatch with high filler content. The quality of filler and water The ratio is 1:1, and the mass ratio of latex to water slurry is 1:1.

[0042] The adhesive system consists of the following...

Abstract

The invention relates to a high-damping anti-aging rubber product which is formed by compounding at least two layers of rubber, and the rubber is prepared from the following raw materials in parts by weight: 60-80 parts of synthetic rubber, 30-60 parts of a reinforcing filling system, 2-5 parts of a plasticizing system, 2-4 parts of an anti-aging system, 1-3 parts of an activating system and 1-3 parts of a vulcanizing system. Compared with the prior art, a reinforcing filling system such as natural rubber grafted white carbon black is adopted, so that the problem of dispersion of a reinforcing filling material is thoroughly solved, the bonding effect of a bonding system is further greatly improved, bonding between layers is firmer, and the bonding strength even exceeds the strength of a rubber body; and the problem of falling between layers cannot occur under most damping use conditions.

Description

technical field [0001] The invention relates to a high damping and anti-aging rubber product and a preparation method thereof, in particular to the preparation of a mixed gel used for vibration damping rubber products, and belongs to the technical field of rubber material science. Background technique [0002] In recent years, with the rapid development of my country's chemical industry, new chemical materials and new varieties have also quickly followed the international development level, which has driven the development of new materials used in automobiles, construction, bridges, aerospace and other industries as high-performance rubber materials. The market demand for ultra-high damping vibration reduction products is also growing. At present, high-performance rubber materials have been listed as support projects of the national "High-tech Research and Development Program" (863 Program), and the market prospect is becoming more and more broad. [0003] Taking the automob...
