Embodiment 1

[0017] A kind of high-damping buffer sound-absorbing rubber, which is composed of a main material and an auxiliary agent with a mass ratio of 1:1. The main material is: 80 parts of bromobutyl rubber and 20 parts of polynorbornene; the auxiliary agent is : 9 parts of insoluble sulfur, 11 parts of accelerator, 6 parts of magnesium oxide, 3 parts of anti-aging agent 4010NA, 3 parts of anti-aging agent NBC, 20 parts of carbon black, 10 parts of high aromatic oil, 15 parts of barium sulfate, 23 parts of kaolin. (all parts are parts by mass)

[0018] The preparation method of the high damping buffer sound-absorbing rubber of the present invention comprises the following steps:

[0019] (1) Prepare the main material according to the proportion, put it into the fully automatic internal mixer, and knead for 0.2h under the condition that the temperature is 120°C and the pressure is 6MPa, and it is set aside;

[0020] (2) Prepare the auxiliary agent according to the proportion, mix the ...

Abstract

The present invention discloses high-damping buffering and sound-absorbing rubber. The high-damping buffering and sound-absorbing rubber consists of main materials and an auxiliary agent, wherein the main materials are a brominated butyl rubber and polynorbornene. The high-damping buffering and sound-absorbing rubber disclosed by the prevent invention has the advantages of being wide in raw material source, low in cost, simple and convenient in preparation method, good in sound-absorbing and noise reducing effect, and the like.

Description

technical field [0001] The invention relates to chemical products and processes, in particular to a high-damping buffer sound-absorbing rubber and a preparation method thereof. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. The rubber industry is one of the important basic industries of the national economy. Rubber products are widely used in all aspects of industry or life. Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products. It not only provides people with daily-use, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber-made production equipment or rubber parts for mining, transportation...
