Description
Technical field
The present invention relates to field of rubber technology, be specifically related to a kind of stretch-proof elastomeric material.
Background technology
Elastomeric material is a kind of macromolecular material that can recover rapidly deformation under large deformation, and it is the important of national economy
One of basic industry, for offer light industry rubber product daily, medical indispensable in people's daily life；For digging, traffic,
The heavy industry such as building, machinery, electronics and new industry provide various rubber systems to produce equipment or rubber components, apply the widest
General.In recent years, developing rapidly of rubber industry, rubber to be had higher requirement, elastomeric material must be towards function
Change, become more meticulous and the direction of diversification is developed.Traditional single elastomeric material can not fully meet the use developed rapidly and want
Ask.Rubber belongs to elastomer and lacks crystallizing power, and intermolecular force is little, and free volume is big, thus its intensity, hardness, wear-resisting
And the performance such as fatigue is the highest, so to improve its performance to rubber through reinforcement.The reinforcing agent that rubber industry is the most traditional is always
White carbon black, although have certain strengthening action, but both reinforcing agents all have the lowest apparent density, is adding in rubber
Time, easily producing and fly upward, processing pollution weight, simultaneously long processing time, mixing energy consumption is big, and black-reinforced goods are single
Black, and both reinforcing agents are difficult to give the higher hardness of goods, more preferable patience etc..In the use environment having,
Requiring that elastomeric material has the performance of stretch-proof, such as tire, therefore, the elastomeric material researching and developing preferable stretch-proof seems intentionally
Justice.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of stretch-proof elastomeric material, has stronger stretch-proof performance.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
A kind of stretch-proof elastomeric material, its raw material includes by weight:
Preferably, a kind of stretch-proof elastomeric material, its raw material includes by weight:
Preferably, a kind of stretch-proof elastomeric material, its raw material includes by weight:
The preparation method of a kind of stretch-proof elastomeric material, comprises the following steps:
(1) it is heated to melting by polyformaldehyde, is subsequently adding expanded perlite, ethylene-vinyl acetate copolymer and slag powders
Mixing and stirring, pulverizes standby after natural cooling；
(2) being added in dimethyl sulphoxide solution by polyacrylonitrile, be stirred making beating, concentration controls at 16-18%, then adds
Enter methacrylic acid mixing and stirring, graphite and fly ash micro-sphere are dried in vacuum drying oven, add according to solid-to-liquid ratio 1:4
Enter deionized water, add sodium lauryl sulphate and continue ultrasonic agitation uniformly, take its supernatant and be added in polyacrylonitrile solution,
Stir 2-3h under room temperature, obtain polyacrylonitrile composite fiber through filtration, standing and defoaming, spinning, carbonization；
(3) product, the LNBR prepared with step (1) after step (2) being prepared composite fibre chopped mix, then
Add 1wt% calcium chloride water flocculate, scrubbed and in air dry oven at 50-70 DEG C be dried 24-30h,
After cooling standby；
(4) nitrile rubber and butadiene-styrene rubber are added in banbury, are warming up to 90-100 DEG C, with the speed of 100-200r/min
Degree banburying 3-5min, adds product, silicone powder and lauric acid prepared by step (3), is warming up to 120-140 DEG C, with 400-600r/
The speed banburying 10-15min of min, adds remaining surplus materials speed banburying 5-7min with 200-400r/min, and thin logical 8
Secondary, obtain elastomeric material.
Beneficial effects of the present invention:
The present invention uses has the good graphite of specific strength height, heat conduction, conduction and Wear vesistance as reinforcing material, because of directly
Being added in rubber to be substantially reduced mechanical performance, reduce service life, graphite is added in the spinning liquid of polyacrylonitrile by the present invention,
The polyacrylonitrile carbon fiber of mineral carbon load is obtained, by LNBR absorption attachment by the way of spinning, oxidation, carbonization
On its surface, it is therefore prevented that excessive gathering, coprecipitated obtain rubber master batch, then with the rubber mixing elastomeric material that obtain then are blended
There is excellent intensity, fatigue resistance, heat conduction, anti-attrition, the characteristic such as corrosion-resistant, the treated expanded perlite of interpolation, ethylene-
Acetate ethylene copolymer and slag powders substantially increase the characteristics such as the thermal insulation of elastomeric material, insulation, elasticity, high-ductility, system of the present invention
Standby elastomeric material, has good stability, heat-insulating property, the most elastic preferably and there is certain intensity, as automobile
Tire has the highest safety coefficient.
