Description
Technical field
The present invention relates to chloroprene rubber technical field, particularly relate to a kind of air conditioner motor shock absorbing ring chloroprene rubber material.
Background technology
Rubber has excellent damping shock absorption characteristic, is widely used in manufacture to prevent vibration, the transmission impacted, absorption from impacting or playing the anti-vibration article of shock absorption.The elastomeric material that anti-vibration article is selected, mainly according to application target and working conditions, mainly considers its Young's modulus, physical strength and dynamic fatigue, creep, stress relaxation, processing characteristics and cost factor.Elastomeric material at present as damping can be divided into six classes:
1. natural rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber are main General Purpose Rubber material;
2. the oil-resistant rubber material based on paracril;
3. the elastomeric material of resistance to weather based on chloroprene rubber;
4. the high-damping rubber material can be used for buffering or shock isolation based on isoprene-isobutylene rubber;
5. the heat resistant rubber material based on terpolymer EP rubber;
6. the high-temperature resistant rubber material based on silicon rubber.
The working temperature of air conditioner motor shock absorbing ring is near room temperature, and contact environment is the ozone that air, air-conditioning and motor produce, the vibrations etc. that equipment produces.According to requirements, sizing material hardness generally 40 degree of levels, after 120 DEG C × 72h is aging, the requirement of changes in hardness within ± 4 degree.Main elastomeric material at present for air conditioner motor shock absorbing ring has: chloroprene rubber, silicon rubber etc.
The most significant advantage of silastic material is its resistance to elevated temperatures, but because its tensile strength generally can only reach a few MPa, cause it resistance toly to subdue, the performance such as antifatigue far below chloroprene rubber material, silastic material is generally only applied to the high temperature resistant occasion not high to mechanical property requirements.The use temperature of air conditioner motor shock absorbing ring, near room temperature, does not need its resistance to elevated temperatures.
Chloroprene rubber material mainly has the following advantages compared with silastic material:
1, have very high mechanical property, because chloroprene rubber belongs to from reinforced rubber, its tensile strength is close with natural rubber, reaches as high as 25.7MPa.The tensile strength of general silastic material only has a few MPa.The mechanics reliability of neoprene neoprene is far above silastic material.
2, excellent fatigue performance, because physical strength is high, the flexing fatigue of chloroprene rubber material can reach more than 40,000 times, and under the same terms, the flexing fatigue performance of silastic material only has about 1/4 of chloroprene rubber.
3, excellent flame resistivity, the flame resistivity of chloroprene rubber is best in conventional rubber, and it has non-hypergolic feature, can from fire from putting out.And silicon rubber itself does not have anti-flaming function.
4, excellent oil resistant, solvent resistance, use range is wide, can be used for general oil resistant operating mode.Silastic material then can not be used for oil resistant operating mode.
Owing to being that to be cross-linked be main oxidising process in chloroprene rubber weathering process, the Young's modulus of aging rear material rises, and cause the Static stiffness of shock absorbing ring to become large, deviation resonance region, makes the cushioning effect of shock absorbing ring reduce, air-conditioning noise raising.Patent of invention CN 102464811A discloses a kind of natural rubber composition of resistance to ozone type for automobile absorber, due in this formula based on natural rubber, chloroprene rubber only accounts for the 2-3% of weight percent, can not meet air conditioning shock-proof circle 120 DEG C × 72h aging after, the requirement of changes in hardness within ± 4 degree.Though silicon rubber can meet the heat resistance of shock absorbing ring, it is all not as chloroprene rubber material in strength and extension property, fatigue performance, flame resistivity and medium-resistance etc., and cost is again higher than chloroprene rubber material simultaneously.
