Composite rubber material with good damping performance

Abstract

The invention discloses a composite rubber material with good damping performance. The composite rubber material is prepared from the following raw materials in parts by weight: 4-5 parts of coumarone-indene resin, 1-2 parts of vulcanizing agent DCBP, 2-3 parts of methyl silicone oil, 24-27 parts of polyacrylonitrile, 12-13 parts of graphite, 3-4 parts of fly ash microspheres, 0.7-1 part of lauryl sodium sulfate, 42-55 parts of liquid nitrile butadiene rubber, 0.6-1 part of methacrylic acid, 52-60 parts of nitrile butadiene rubber, 20-25 parts of styrene butadiene rubber, 12-14 parts of ceramic powder, 4-5 parts of carboxymethyl cellulose, 2-3 parts of sodium metabisulfite, 10-13 parts of glass beads, 0.2-0.4 part of sodium sorbate and 12-13 parts of calcium borate. The damping rubber disclosed by the invention has good damping, sound insulation and buffer properties as well as perfect heat resistance and corrosion resistance; and moreover, the rubber is not aged easily and has long service life.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a composite rubber material with good damping performance. Background technique [0002] Rubber material is a polymer material that can quickly recover from deformation under large deformation. It is one of the important basic industries of the national economy. It provides light industrial rubber products for daily use and medical use that are indispensable in people's daily life; for mining , Transportation, construction, machinery, electronics and other heavy industries and emerging industries provide a variety of rubber production equipment or rubber parts, which are widely used. In recent years, the rapid development of the rubber industry has put forward higher requirements for rubber products, and rubber materials must develop in the direction of functionalization, refinement and diversification. The traditional single rubber material can no longer fully meet the rapidly d...

The most traditional reinforcing agents in the rubber industry have always been carbon black and white carbon black. Although they have a certain reinforcing effect, both of these two reinforcing agents have very low apparent densities. When they are added to rubber, they are easily produced. Feiyang, heavy processing pollution, long processing time, high energy consumption for mixing, and the carbon black reinforced product is a single black color, and these two reinforcing agents are difficult to endow the product with higher hardness and better air resistance sex etc.

[0003] Graphite is a layered material with excellent lubricating properties and a very high shape factor in the exfoliated state. Graphite is one of the materials with the highest specific strength and has unique functional properties such as electrical conductivity and thermal conductivity. And the cost is low. As a reinforcing material for rubber, it can improve its tribological properties. However, due to the inert nature of the graphite material itself and the Van der Waals force between the layers, directly adding it to the rubber will greatly reduce its mechanical properties and shorten the service life.
