Description
Technical field
The present invention relates to fire-retardant yielding rubber technical field, more particularly to a kind of environmental protection flame retardant ethylene propylene diene rubber damping material
Material and preparation method thereof.
Background technology
With the rapid development of industry, vibration and noise have been the serious problems of every field development, and it have impact on product
Quality, performance accuracy is reduced, shorten life of product, jeopardize the security of product, polluted environment and influence health of human body.For
Noise and vibration caused by the vehicles such as automobile, household electrical appliances and industrial machinery are prevented, except reducing or eliminating vibroseis
Vibrations outside, more practical way is the various anti-vibration articles of utilization, and wherein rubber damping product is particularly important group
Into part.The elasticity of rubber has the characteristics of elastic and sticky, also known as viscoplasticity concurrently, and its elasticity comes from the long-chain molecule of its curling
Conformation change, but the motion of long-chain molecule is hindered by rubber molecule interphase interaction, therefore shows viscosity again, is exactly
This viscoplasticity of rubber makes it have good damping and shock-absorbing capacity, can effectively isolate vibrations object and slow down vibrations
Body shakes, and is widely used in the damping of the various vehicles, instrument and equipment, industrial machinery.
Ethylene propylene diene rubber can be provided preferably due to its excellent ageing-resistant performance and easily filling by peroxide cure
Resistance against compression energy, be increasingly used for anti-vibration article, but ethylene propylene diene rubber damping and amortization is poor, peroxide vulcanizing system makes
Obtaining the deformability of rubber reduces, and the fatigue durability of sizing material declines during vibrations, it is impossible to meets performance requirement, simultaneously because subtracting
Shake elastomeric material absorbs unnecessary vibration, causes it to be easier to generate heat, the potential danger of burning be present.It is at present to use red phosphorus more
As the fire retardant of vibration isolation rubber sizing material, it the advantages of be damping behavior and the heat durability of not damaging vibration isolation rubber, together
When can also suppress the generation of toxic gas, but its flame retardant effect or not as good as halogen based flame retardant wants to obtain high fire-retardance
Effect, it is necessary to which a large amount of to use, this just inevitably reduces the performance of sizing material, makes its damping capacity further reduce.Have
Researcher improves the fire retardancy of rubbery system using red phosphorus/magnesium hydroxide compounding as efficient flame-retarding agent, can be with less amount of
Arrange in pairs or groups relatively large amount of magnesium hydroxide of red phosphorus just can reach good flame retardant effect, but magnesium hydroxide and ethylene propylene diene rubber
Molecule associativity is poor, easily separates out failure.《China Synthetic Rubber Industry》" the magnesium hydroxide particle diameter pair that 6 periodicals of volume 27 in 2004 are stepped on
The result of study of the text of the influence of its filling ternary ethlene propyene rubbercompound material mechanical property and fire resistance " one shows magnesium hydroxide
The smaller reinforcement of particle diameter and fire resistance are better, and after carrying out surface modification treatment to magnesium hydroxide with silane coupler, although carrying
Its high compatibility with ethylene propylene diene rubber, but also because heat transfer is more when the introducing of organic matter causes material combustion
Easily, ignitor firing time shortens, and influences anti-flammability.
The content of the invention
The present invention in order to make up prior art the defects of, there is provided a kind of environmental protection flame retardant ethylene propylene diene rubber vibration-absorptive material and its
Preparation method.
