Abstract

The invention relates to a foamed rubber sealing material and a manufacturing method thereof. The foamed rubber sealing material is composed of 100 parts of main material, 6-8 parts of reinforcing colorant, 20-40 parts of plasticizer, 1-2 parts of dispersing agent, 8-12 parts of foaming agent, 8-10 parts of vulcanizing agent, 1-2 parts of stearic acid, 1-2 parts of accelerator, 3-6 parts of protective agent and 60-80 parts of filler. The main material CR:EPDM:NR ratio is 70:(10-20):(10-20), the plasticizer brown ointment:naphthenic oil ratio is 1:3, the accelerator DETU:TMTM ratio is 1:1, and the protective wax:anti-aging agent 445:anti-aging agent ODA ratio is 1:1:1. The manufacturing method comprises the following steps: rubber mixing, powder mixing, discharging, primary vulcanizing and foaming, secondary vulcanizing and foaming, and normal-temperature natural cooling for 10-15 days. The foamed rubber sealing material has the advantages of low density, high toughness, low thermal conductivity, water resistance, favorable aging resistance, excellent elasticity, excellent shock-absorbing capacity, excellent flame retardancy, environmental protection and no toxicity.

Description

technical field [0001] The invention relates to a foamed rubber sealing material, belonging to the technical field of foamed rubber sealing materials. The invention also relates to a manufacturing method of the foamed rubber sealing material. Background technique [0002] At present, the NBR / PVC blended foam rubber mainly used in the market has low tensile strength, tear strength and elongation. Ordinary materials with low requirements for shock absorption and sealing, but with the demand for the use of foamed rubber in the fields of automobiles, high-speed rail, and electronics, people have put forward new performance requirements for foamed rubber. [0003] Its performance index of existing NBR / PVC blend foam rubber is as follows: [0004] [0005] Obviously, the existing NBR / PVC blended foam rubber cannot meet the requirements for the use of foam rubber in the fields of automobiles, high-speed rail, and electronics. Contents of the invention [0006] The primary p...
