Description
Technical field
A kind of tire rubber powder, for making tire, belongs to rubber powder technical field.
Background technology
Since the seventies, industrially developed country has a great development in terms of the secondary utilization of waste old.Especially
Since it is the nineties, room temperature has been worked out in succession and cryogenic crushing process manufactures the method for fine vulcanized rubber powder and forms scale
Production.Fine glue powder (80--120 mesh) is a kind of important additive.For example, fine glue powder is added to (one in natural rubber
As rubber incorporation up to 50%), the dynamic properties such as the static properties of rubber powder, endurance can be improved.In Germany, tire
20% rubber powder is added in product, its wearability can be improved, extend the service life of tire, rubber powder is thinner, and the amplitude of raising is got over
Greatly.The price of rubber powder only has the 1/3 1 1/2 of natural rubber, thus can greatly reduce tire cost.Fine glue powder can also add
In being added to plastics, the rubber-plastics material produced, intensity is high, wear-resisting, elasticity range of application that is good, expanding plastics.In tradition
Construction material in add fine glue powder, shockproof, anticracking, leakproof, durable new product building materials can be produced.
By 2010, Chinese junked tire burden up to 200,000,000, and will make us surprised speed with about 65,000,000 every year
Increase, and at present recovery utilization rate only has 30%.China is a rubber applications big country, and the Year's consumption of rubber ranks first in the world
Position；At the same time, China is again the serious deficient country of a rubber sources, and the 60% of Year's consumption needs import, and short
The method of basic solution is not had in time.Damaged tire is a kind of regenerated resources, is in field of new " treasured ", waste and old wheel
Tire process must well, dig a gold mine not to the utmost.Especially in the case where China rubber sources is in short supply, waste rubber goodses
Regeneration has more positive meaning.
Chinese tire recycles industry and obtains the development advanced by leaps and bounds, and has successfully established tire and recycle greatly
The status of state, Chinese rubber powder yield reaches 300,000 tons within 2006, and 50% is increased than last year.
Compared with the tire yield of rapid growth, although the reclaimed rubber and rubber powder of China supplement a part of rubber money
Source, but China remains for many years the big natural rubber importer of the first in the world, more than 70% natural rubber dependence on import, rubber
Industrial Security or even national security receive serious challenge.Therefore, China moves towards wheel in the urgent need to recycling big country from tire
Foetal circulation is using power.
And be all to prepare rubber powder again in order to ensure the quality of rubber powder in prior art, this is just unfavorable for reclaiming in tire
Rubber powder recycling, so as to cause the waste of resource, although in prior art also someone will reclaim tire in rubber powder
Using preparing new sizing material again, the toughness of the sizing material prepared, service life and anti-skidding effect on driving birds is not good.
The content of the invention
The present invention provides a kind of tire rubber powder for above-mentioned weak point, solves to be reclaimed in tire in prior art
Rubber powder using preparing new sizing material again, the toughness of the sizing material prepared, service life and anti-skidding effect on driving birds is not good are asked
Topic.
To achieve these goals, the technical solution used in the present invention is as follows：
A kind of tire rubber powder, it is characterised in that：Including natural rubber, thermoplastic elastomer (TPE), viscosifier, plasticizer, anti-
Oxidant, cross-linking agent, foaming agent, antilubricant, reclaimed rubber and rubber powder；
Wherein mass ratio is：8%, thermoplastic elastomer (TPE) being accounted for including natural rubber and accounting for 21%, viscosifier account for 41%, plasticizer
Account for 10%, antioxidant and account for 1%, cross-linking agent and account for 1%, foaming agent and account for that 2.5%, antilubricant accounts for 0.5%, reclaimed rubber and rubber powder is accounted for
15%.
Further, the main component of the natural rubber is the natural polymer of cis- Isosorbide-5-Nitrae-polyisoprene.
Further, the composition of the cis- Isosorbide-5-Nitrae-polyisoprene is 91%~94%, protein, fatty acid, ash, sugar
The composition of class is 9%~6%.
Further, the thermoplastic elastomer (TPE) is lactoprene or synthetic rubber.
Further, the viscosifier are modified rosin resin.
Further, the plasticizer is citric acid ester type, epoxy soybean oil plasticiser.
Further, the antioxidant is BHA, BHT or PG.
Further, the cross-linking agent is cumyl peroxide；Foaming agent is carbon black.
In sum, as a result of above-mentioned technical proposal, the invention has the beneficial effects as follows：
First, the present invention is again proportionally added into ground rubber, and freshly prepared other component ratios of laying equal stress on not only can allow
The rubber powder of recovery is reused, and can also allow the rubber powder for remaking identical in quality with the rubber powder that new material makes, and can play anti-wheel
Tire quality is really up to the mark, occurs slight crack in the case where exposing to wind and rain, and the addition of antilubricant plays the role of can also tire anti-skidding, increases
The coefficient of friction of tire and ground is added, the material toxicity of employing is few, can play environmental protection, the body that can protect staff is good for
Health；
2nd, the present invention uses viscosifier, for reducing viscosity, raising when thermoplastic elastomer (TPE) is heated by viscosity, bonding
Intensity, the heat resisting temperature for adjusting hot-melt adhesive powder and open assembly time, improve operability and reduces cost；
3rd, the present invention have selected plasticizer, for increase for automobile tire macromolecule rubber powder ductility (and flowing
Property), reduce hardness, improve elongation at break and its is low temperature resistant, the macromolecule rubber powder for being used in automobile tire adapts to vehicle tyre
Run up in low temperature without departing from and pierced through by sharp object and steel nail or can be self-styled after bullet punctures；
4th, the cross-linking agent that uses of the present invention has and increases the glue-line that hot melting spraying formed and have resistance to elevated temperatures and persistently
Property.
