For example, the Chinese invention patent with the publication (announcement) No. CN110358205A discloses a high-damping rubber raw material for automobile vibration reduction. Titanium black 20-40; nano diatomite 20-40; fine carbon black 5-15; naphthenic oil 10-50; antioxidant 2-6; nano zinc oxide 2-8; coupling agent 1-7; Oxygen resin 2-6; Hard acid 1-5; Although this technical scheme adopts chlorinated butyl rubber or butyl rubber to replace natural rubber, it is compounded with nano-titanium black and nano-diatomaceous earth, and the automobile is manufactured through additives High-damping rubber raw materials are used for vibration-damping products; high-damping rubber has large damping, strong vibration-absorbing ability, and good vibration-isolation ability of the suspension system, which can obtain the best material properties and can well meet the high damping and heat-resistant conditions of rubber materials. However, this high-performance high-damping rubber material generally has low loss factor (less than 1.0) and poor vibration damping ability.

Abstract

The invention relates to a high-damping rubber material with high vibration attenuation performance. The material is prepared from 100 parts of brominated butyl rubber, 40-60 parts of a reinforcing agent, 20-60 parts of a filling agent, 10-30 parts of a plasticizer, 1-3 parts of an acid-base regulator, 1-3 parts of a release agent, 2-6 parts of an anti-aging agent RD, 10-40 parts of a Tg regulator, 2-10 parts of an activating agent, 1-2 parts of an activating aid and 4-16 parts of a vulcanizing agent. By replacing the main rubber, the carbon black, the Tg regulator, the vulcanization system and the like, the loss factor of the high-damping rubber material is high (greater than 1.0), and the vibration attenuation capacity is high; through the Tg regulator, the loss factor peak value of thematerial becomes greater, and meanwhile, the peak value also falls within the use temperature range; the vulcanization system enables long cross-linking bonds to be formed among molecular chains so asto increase displacement of forced movement of the molecular chains, so that the loss factor of the material is increased; in addition, the brominated butyl main rubber and the superfine carbon blackcan overcome greater inherent internal friction when the molecular chain of the rubber is displaced, so that the loss factor of the material is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of rubber materials, in particular to a high-damping rubber material with high vibration-absorbing performance. 【Background technique】 [0002] At present, the high damping rubber material with high vibration reduction generally adopts one or two blends of butyl rubber or halogenated butyl rubber as the main rubber, carbon black or white carbon black as the reinforcing agent, and mica or diatomaceous earth as the reinforcing agent. Filling modifiers and petroleum resins are used as Tg regulators, and additives commonly used in rubber vulcanization, such as processing aids, anti-aging agents, plasticizers, coupling agents and vulcanizing agents, are added as basic raw materials for high-damping rubber formulations. For example, the Chinese invention patent with the publication (announcement) No. CN110358205A discloses a high-damping rubber raw material for automobile vibration reduction. Titanium black 20-...
