Description
Technical field
The present invention relates to rubber materials, specially a kind of preparation method of elastomeric material.
Background technology
The rubber of early stage is taken from the latex of the plants such as rubber tree, kok-saghyz, manufactured flexible, insulation after processing
Property, the material of impermeable water and air.Synthetic rubber is then obtained by the aggregated reaction of various monomers.Rubber is widely used in work
Industry or life each side, such as automobile tire, electric wire, insulating materials, ball stationery sports goods, toy, rubber gloves, locomotory apparatus
Material dispensing etc..And the defects of high temperature degradation resistance difference be present in existing General Purpose Rubber, poor heat resistance, the rubber that fine jade is produced
Product quality is relatively low.
So how to design a kind of preparation method of elastomeric material, turning into us will currently solve the problems, such as.
The content of the invention
It is an object of the invention to provide a kind of preparation method of elastomeric material, has wearability good, light, resistant to elevated temperatures
Lacking for high temperature degradation resistance difference be present in feature, the General Purpose Rubber that the product being prepared by the method for the present invention overcomes prior art
Fall into, add the tear resistance of rubber, the new material effect prepared is more preferable than original rubber heat resistance, easy to use, this hair
The bright rubber product quality produced rises, the problem of can proposing to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of elastomeric material, prepared by the raw material of following mass fraction：It is curing agent 1-3 parts, rubber accelerator 0.5-2 parts, wooden
Unpigmented rubber auxiliary agent 3-6 parts, ethyl acetate 1-4 parts, choline 3-9 parts, paraffin 3-5 parts, silicic acid 6-10 parts, resin 2-8 parts, pyrrolidines
The triethanolamine salt 7-9 parts of keto carboxylic acid one, sodium benzoate 3-19 parts, nitrile rubber 10-18 parts, ethylene propylene diene rubber 5-13 parts, 1,
2,5,6- tetrahydrochysene benzylalcohol 0.2-0.9 parts, sodium nitrilo triacetate salt 1-3 parts, dihydroterpinyl acetate 1-3 parts, hydracrylic acid 3-
12 parts, acetic acid 3-10 parts, butadiene-styrene rubber rubber 10-30 parts, hydrogenated nitrile-butadiene rubber 5-15 parts, epoxidized soybean oil 5-12 parts, acrylic acid

According to above-mentioned technical proposal, the curing agent includes the adjustable structure unit with stable catenation, institute
State stable catenation and can adjust to stable annular arrangement, the wherein annular arrangement and include the composition portion of catenation
Point, wherein at least two end part shows chemical adelphotaxy, and the annular arrangement can be by separating
The two end parts adjust back catenation by annular arrangement.
According to above-mentioned technical proposal, the rubber accelerator is whether just to first check for equipment operation by alkali soluble process
Often, section door switch it is whether correct, determine it is errorless after can be operated；Add water 1000-1200L to alkali soluble tank, then put into promotion
Agent MBT450-500kg, add water 300L, start stirring, vapour heating is directly opened when being mixed into atherosclerotic to MBT and water, treats that temperature rises to
Stop heating, 12~24 hours sedimentation times when optimal for 35~45 DEG C 42；Oxidation operation checks whether oxidation tank blowing section door closes
Close, then check whether chlorine pipeline is unimpeded and has No leakage with air；Check in errorless backward oxidation tank plus water about 2000~
3000L, 2500L sodium salt liquid is squeezed into from settling tank to oxidation tank, opens and pH value is surveyed after stirring；Temperature is maintained in oxidizing process
55~65 DEG C, and, when PH is 8, increase monitoring number, reduced with the situation of change of PH test paper monitoring oxidation material liquid PH value at any time
Logical chlorine speed, when PH=5~7, chlorine section door is closed, after continuing air blast 10 minutes, repetition measurement pH value, pH value is stable 5~7, treats
Inlet temperature can continue material when rising to 140 DEG C, during continuous continuous material inlet temperature control at 140~180 DEG C, outlet temperature 75~
100℃；After drying, parking is by feeder, disintegrating machine, electrical heating, vapour heating, steam flow sieve, disintegrating machine, excessively discharging airlock, sieve
Made of after machine, blower fan sequence stop.
