Description
Technical field
The present invention relates to technical field of rubber material, be specifically related to a kind of new waterproof 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 and white carbon, although there is certain strengthening action, but both reinforcing agents all have the lowest apparent density, to rubber
When adding in glue, easily producing and fly upward, processing pollution weight, simultaneously long processing time, mixing energy consumption is big, and black-reinforced goods
For single black, and both reinforcing agents are difficult to give the higher hardness of goods, more preferable resistance to breathability etc..
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of new waterproof elastomeric material, gives rubber the most resistance to
Breathability and higher hardness.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
A kind of new waterproof elastomeric material, its raw material includes by weight:
Preferably, a kind of new waterproof elastomeric material, its raw material includes by weight:
Preferably, a kind of new waterproof elastomeric material, its raw material includes by weight:
Preferably, the one during softening agent is paraffin oil, Colophonium, coal tar, white oil, naphthenic oil.
Preferably, softening agent is paraffin oil.
Filler is the one in hydrated SiO 2, active hargil, magnesium carbonate.
The preparation method of a kind of new waterproof elastomeric material, comprises the following steps:
(1) Nano silica sol, VAE emulsion, hydrated SiO 2, barium sulfate and magnesium hydroxide are mixed according to weight ratio 1:
3 add deionized water mixes well, and adds calcium propionate and is heated to boiling under being stirred continuously, after dope to be formed, grinds after drying
Grind standby;
(2) being added in dimethyl sulphoxide solution by polyacrylonitrile, be stirred making beating, concentration controls, 13%, to add
Methacrylic acid mixing and stirring, is dried graphite and fly ash micro-sphere in vacuum drying oven, adds according to solid-to-liquid ratio 1:4
Deionized water, adds sodium lauryl sulphate and continues ultrasonic agitation uniformly, take its supernatant and be added in polyacrylonitrile solution, room
Stir 2-3h under temperature, obtain polyacrylonitrile composite fiber through filtration, standing and defoaming, spinning, carbonization;
(3) product, the LNBR prepared with step (1) after step (3) being prepared composite fibre chopped mix, then
Add 1wt% calcium chloride water flocculate, scrubbed and in air dry oven at 80 DEG C be dried 25h, after cooling
Standby;
(4) nitrile rubber and butadiene-styrene rubber being added in banbury, be warming up to 90-100 DEG C, the speed with 250r/min is close
Refining 3-5min, adds product, tetramethylthiuram disulfide and paraffin oil prepared by step (3), is warming up to 120-140 DEG C, with
The speed banburying 10-15min of 400-600r/min, adds remaining surplus materials speed banburying 5-with 200-400r/min
7min, thin logical 8 times, obtains 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 hydrated SiO 2 of interpolation, sulfur
Acid barium and magnesium hydroxide can effectively improve the spies such as fire-retardant, the dielectricity of elastomeric material, waterproof, insulation and chemical stability
Property, the present invention uses the water proof rubber material obtained by above-mentioned formula, not only has good water resistance, the most acidproof, oil resistant,
Fire-retardant, it is possible to well to meet the needs in producing, be worthy to be popularized.
