Description
Technical field
The present invention relates to resource regeneration technical field, more particularly to a kind of method that Waste tire regeneration utilizes.
Background technology
Waste old is the waste polymer material except waste or used plastics Wai Ju second places of the world, and it is mainly derived from waste and old wheel
Tire.The bulk deposition of junked tire, not only result in the waste of resource, grow mosquito, and be easy to cause fire, its flame
It is difficult to put out.Because waste old is heat cured polymeric material, there are higher toughness and elasticity, it is difficult to degrade,
And recycling technique is extremely complex, cost is very high.Therefore, iterative method or improvement junked tire processing mode, maximum journey
Recycle the rubber sources put aside as useless degree, can not only help solve the problems, such as Domestic Resources scarcity, more to developing a circular economy,
Conservation-minded society is established to be significant.
Recycling junked tire mainly has four class methods at present：1. the intact renovation regeneration of carcass, equivalent to prolonging
The service life of tire has been grown, it is general to be renovated using 2~3 times per tires.2. it is used as fuel after junked tire is cut to send out
Electricity, its calorific value are all higher than conventional fuels such as timber, bituminous coal.3. chemistry, high temperature or microwave cracking recovery carbon black and fuel oil, but so far
Do not occur large-scale production device untill the present.4. micelle and fine glue powder is made, fine glue powder production technology content is high, uses
Way is more, and market potential is big, is promoted to the emerging environmental protection industry for possessing bright prospects.Wherein, it is current to produce micelle or rubber powder
Handle junked tire most one of method of future.By junked tire by cutting, crushing, separating, screening, the process such as grinding,
Due to the difference of technological equipment, the micelle product of gained varies.The maximum feature for producing rubber powder is that process is simple, this
Compared with the production of reclaimed rubber, while Various Complex process (such as desulfurization and refining) is eliminated, also save substantial amounts of special
With factory building, equipment, power and personnel, and save the industrial chemicals such as softening agent, tackifier and activator, also in the absence of waste water and
Dust pollution, this has been inherently eliminated secondary pollution caused by production reclaimed rubber.The fine glue powder performance produced is also excellent
In reclaimed rubber.In rubber industry, fine glue powder can be widely applied in the rubbers such as tire.Appropriate vulcanizate
In powder incorporation sizing material, although tensile strength slightly influences, its dynamic mechanical can but greatly improve, processing technology,
Very property and mobility can all be improved.Therefore, it is current society further to enrich and improve the method that Waste tire regeneration utilizes
Meeting urgent need to resolve and question of common concern, and the research to relevant issues also has far-reaching social reality meaning.
The content of the invention
In order to promote the circular regeneration of junked tire, the utilization rate of rubber sources is improved.The invention provides a kind of waste and old
