Description
Technical field
The present invention relates to technical field of rubber material, particularly relate to a kind of wear-resistant vibration-damping elastomeric material.
Background technology
Along with the development of society, people more and more focus on comfort level, and especially in automobile industry, people are pursuing vehicle body damping always, and existing automobile vendor often adopts cis-1,4-polybutadiene rubber and natural rubber to reduce vehicle body shake and noise.Wherein cis-1,4-polybutadiene rubber is the abbreviation of cis 1，4-polybutadiene rubber, and its molecular formula is (C4H6) n, belongs to mixture.Cis-1,4-polybutadiene rubber is the synthetic rubber of the compound with regular structure obtained by polymerizing butadiene, compares with styrene-butadiene rubber(SBR) with natural rubber, and the winter hardiness of the cis-1,4-polybutadiene rubber after sulfuration, wear resistance and elasticity are excellent especially, and under dynamic load, heating is few, and ageing resistance is fair.But existing reinforcement sulfuration cis-1,4-polybutadiene rubber material is still difficult to meet more and more stricter damping requirement, need now a kind of wear resistance strong, the elastomeric material of damping effect excellence.
Summary of the invention
The technical problem that basic background technology exists, the present invention proposes a kind of wear-resistant vibration-damping elastomeric material, and wear resisting property is excellent, and has snappiness, can effectively damping.
A kind of wear-resistant vibration-damping elastomeric material that the present invention proposes, its raw material comprises by weight: cis-1,4-polybutadiene rubber 50-60 part, terpolymer EP rubber 10-15 part, polyvinyl chloride thermoplastic elastomer 20-25 part, SULPHUR POWDER 3-4 part, altax 1.5-2.5 part, TM monex TM1-2 part, trioctyl trimellitate 5-8 part, tributyl citrate 3-4 part, ground barium sulfate 15-20 part, magnesium oxide 6-9 part, hard (china) clay 12-16 part, kaolin 10-15 part, red phosphorus 9-12 part, anti-aging agent RD 2-3 part.
Preferably, cis-1,4-polybutadiene rubber is high-cis cis-1,4-polybutadiene rubber.
Preferably, in cis-1,4-polybutadiene rubber, cis Isosorbide-5-Nitrae content is 98-99%.
Preferably, the weight ratio of SULPHUR POWDER, altax, TM monex TM is 3.5:2:1.5.
The present invention adopts following technique to prepare: cis-1,4-polybutadiene rubber, terpolymer EP rubber, polyvinyl chloride thermoplastic elastomer glue are placed in Banbury mixer and plasticate evenly, continue to add trioctyl trimellitate, tributyl citrate, ground barium sulfate, magnesium oxide, hard (china) clay, kaolin, red phosphorus, anti-aging agent RD mixing evenly after, vacuumize to extrude and obtain mixture, maintenance negative pressure is 0.6-0.9MPa; Mixture is placed in cooler to be cooled to room temperature and to obtain mixed rubber; Mixed rubber, SULPHUR POWDER, altax and TM monex TM are put in vulcanizer and mix, then carry out sulfuration, then binder removal, slice, cooling leave standstill 40h, obtain wear-resistant vibration-damping elastomeric material.
The present invention adopts cis-1,4-polybutadiene rubber, terpolymer EP rubber and polyvinyl chloride thermoplastic elastomer to be major ingredient, and make the present invention possessing elastomeric while, consistency is fine; Add ground barium sulfate, magnesium oxide, hard (china) clay, kaolin, red phosphorus again as reinforcing filler, significantly improve wear resisting property of the present invention, lower cost of the present invention, wherein red phosphorus is also as heat-proof combustion-resistant agent, and be aided with tributyl citrate and trioctyl trimellitate, improve the solubleness of reinforcing filler in major ingredient and dispersiveness; SULPHUR POWDER, as vulcanizing agent, can increase cross-linking density, makes performance of the present invention more excellent, forms vulcanization system with SULPHUR POWDER, altax, TM monex TM, and make vulcanization rate of the present invention fast, compression set is low, and damping effect is excellent.
