Background technology
Rubber industry is one of important foundation industry of national economy.It not only provides daily life the indispensable light industry rubber product such as daily, medical for people, and provides various rubber production unit processed or rubber components to the heavy industry such as digging, traffic, building, machinery, electronics and new industry.Visible, the product category of rubber industry is various, and backward industry is very wide.In recent years, rubber industry was much developed, and the existing segmented industry is steadily increasing, new develop rapidly of the untreated rubber segmented industry, but simultaneously, yet there are the problems such as environment, resource, disaster, innovation in rubber industry.
Country advocates rubber industry safety, energy-saving and environmental protection and cleaner production policy, and is attended by the most momentous results.Especially Rubber Chemicals Industries is actively adjusted the product mix, and the environmental type auxiliary agent increases substantially, and anti-aging agent improved seeds output ratio has reached 80%, and promotor reaches 50%, and poisonous, harmful, high carcinogenic NOBS turnout is effectively controlled; The waste rubber comprehensive utilization ratio reaches more than 65%, and reclaimed rubber and rubber powder post-treatment utilize field to enlarge.
Environment-protective rubber material is an important ring of whole adjustment of industrial structure, is related to the development of whole industry to high-tech, sustainability.At present the research and development of environment-friendly rubber constantly heated up.201210459394.8 a kind of novel environment friendly elastomeric material is disclosed, with terpolymer EP rubber, fiber, sulphur, coumarones etc. are main raw material; 201210322305.5 disclose a kind of environment-protective rubber material, main component is fire retardant, film coalescence aid, talcum powder, softening agent, carbon black, calcium carbonate, polyvinyl chloride and vulcanization aid.They all exist that preparation cost is high, the problem of complex process etc., thereby cost performance is not high, can not meet human consumer's requirement, is difficult to promote on market.Therefore, the present invention is directed to above situation, develop the environment-protective rubber material of a kind of reasonable price, environmental protection, the development trend in applicable market.
Summary of the invention
The purpose of this invention is to provide kind of environment-protective rubber material and preparation method thereof, this elastomeric material cost is low, and manufacture craft is simple, and performance is good, and environmental protection can be recycled again.
In order to address the above problem, the technical solution adopted in the present invention is:
A kind of environment-protective rubber material, the weight part of each component is:
40 ~ 45 parts of rubber, 2 ~ 5 parts, zinc oxide, 7 ~ 10 parts, calcium carbonate, 12 ~ 17 parts, butter, 10 ~ 15 parts of albumen stone flours, 3 ~ 6 parts of carbon blacks, 2 ~ 5 parts of polyvinyl chloride, 3 ~ 6 parts of vulcanization aids.
A kind of preparation method of environment-protective rubber material, comprise the steps:
Under agitation add above-mentioned materials, react 22 ~ 25 hours at 55 ℃ ~ 58 ℃ temperature; After reaction finishes, adopt ammoniacal liquor that the pH value of solution is adjusted to 6.8 ~ 7.2, pass into steam-heated cal(l)andria to latex coagulation, dehydration, rinsing, granulation, get final product at 65 ℃ ~ 70 ℃ drying 48 ~ 55h.
The invention has the beneficial effects as follows:
the invention provides a kind of environment-protective rubber material, its good springiness, strong, the acidproof corruption of anti-aging power be high, resistance to wear, good flame retardation effect, nontoxic to human body, guarantee to eliminate human consumer and user's potential safety hazard, can again reclaim, be conducive to save energy, be conducive to environmental protection, be conducive to increase economic efficiency.The preparation method of environment-friendly rubber of the present invention,, preparation technology is simple, and cost is low, suitable to industrial scale operation.
