Description
Technical field
The present invention relates to field of rubber technology, and in particular to a kind of high-performance ethylene propylene diene rubber.
Background technology
The weather resistance of ethylene propylene diene rubber brilliance becomes the substitute products of traditional rubber-plastics material.It is with ethene
(CH2=CH2), propylene (CH2=CH-CH3) it is principal monomer, through polymerisation in solution and to add undersaturated Third monomer (non-conjugated
Alkadienes) made of terpolymer, belong to saturated carbon chains rubber.Ethylene propylene diene rubber have excellent chemical stability,
Good electrical insulation capability, ageing-resistant performance and water resistance.It both can be widely used for the physical culture of less demanding to environmental condition
In the industry such as articles for use, all kinds of buildings and refrigeration, air-conditioning, can be also widely applied to the auto parts and components to environmental requirement higher, medicine,
The fields such as military project apparatus.Although ethylene propylene diene rubber has excellent steady chemical structure, in the long-term use, by
From surface aging internally can gradually occur for the effect to light, oxygen, water, ozone etc., so as to cause its ageing-resistant performance, waterproof to resist
The degenerations such as oozing property are serious.
The content of the invention
The present invention provides a kind of high-performance ethylene propylene diene rubber, which has preferable resistance to ag(e)ing, prevents
Water-based, impermeability etc. is significantly improved, be particularly suitable for rubber hose that open air etc. is directly exposed under sunlight or its
His construction material, durability is good, substantially prolongs its service life.
The present invention is achieved through the following technical solutions：
A kind of high-performance ethylene propylene diene rubber, its raw material include following component by weight：
140~160 parts of ethylene propylene diene rubber, 18~25 parts of vulcanizing agent, 3~8 parts of polyether sulfone, phthalimide 2~5
Part, 20~25 parts of methyl silicon resin, 6~10 parts of pitch.
Preferably, a kind of performance ethylene propylene diene rubber, its raw material include following component by weight：
155 parts of ethylene propylene diene rubber, 22 parts of vulcanizing agent, 5 parts of polyether sulfone, 3.5 parts of phthalimide, methyl silicon resin
23 parts, 7.5 parts of pitch.
Further, the vulcanizing agent is benzoyl peroxide or sulphur.
A kind of preparation method of high-performance ethylene propylene diene rubber, it is characterised in that include the following steps：
1) polyether sulfone, phthalimide, methyl silicon resin are added in ethylene propylene diene rubber successively according to proportioning
Fully it is kneaded；
2) the mixing product of step 1) is placed into 8~10h, back mixing is carried out on kneading machine after adding pitch, adds sulphur
Agent, is vulcanized in vulcanizer；
3) it is sulfur product obtained by step 2) is hot-forming, that is, obtain the high-performance ethylene propylene diene rubber.
Further, in the step 2), curing temperature is 180~210 DEG C, and vulcanization time is 20~35min.
Beneficial effects of the present invention：Polyether sulfone is added in ethylene propylene diene monomer (EPDM) material, ethylene propylene diene rubber can be improved
Heat resistance；Phthalimide is added, may be such that the ethylene propylene diene rubber of preparation has excellent ageing-resistant performance, improves it
Tear resistance and wearability；Adding pitch can also make the water resistance of ethylene propylene diene rubber get a promotion.The ternary second of the present invention
Third rubber has excellent heat resistance, crack resistance and water proofing property at the same time, is particularly suitable for open air etc. and is directly exposed under sunlight
Rubber hose or other construction materials, durability is good, substantially prolongs its service life.
