Description
Technical field
A kind of tire blow-out 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, normal 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
It is added in 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 recovery utilization rate only has 30% at present.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 " treasured ", waste and old wheel in field of new
Tire process must well, a pick 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.
Proposed since " Developing Circulation Economy is built a conservation-minded society " from the Fourth Plenary Sessions of its Sixteenth Central Committee of party in 2004,
Chinese tire recycles industry and obtains the development advanced by leaps and bounds, and has successfully established the status that tire recycles big country
2006, Chinese rubber powder yield reached 300,000 tons, and 50% is increased than last year.
Compared with the tire yield of rapid growth, although the reclaimed rubber and rubber powder of China are provided supplemented with a part of rubber
Source, but China is still 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
Fetal circulation is using power.
And be all to prepare rubber powder again in the prior art in order to ensure the quality of rubber powder, this is just unfavorable for reclaiming in tire
Rubber powder recycling, so as to cause the waste of resource, although in the 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, anti-tie effect on driving birds is not good, anticorrosive, high temperature resistant
Effect on driving birds is not good and it is big for environment pollution the problems such as.
The content of the invention
The present invention provides a kind of tire blow-out rubber powder for above-mentioned weak point, solves in the prior art by recycling round
Rubber powder in tire is the toughness of the sizing material prepared, service life, anti-tie effect on driving birds is not good, anti-using preparing new sizing material again
The problems such as burn into high-temperature resistant result is not good and big for environment pollution.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of tire blow-out rubber powder, it is characterised in that：Including natural rubber, thermoplastic elastomer (TPE), tackifier, plasticising
Agent, antioxidant, crosslinking agent, catalyst, basalt fibre, reclaimed rubber and rubber powder；
Wherein mass ratio is：6%, thermoplastic elastomer (TPE) being accounted for including natural rubber and accounting for 25%, tackifier account for 40%, plasticizer
Account for 9%, antioxidant and account for 2%, crosslinking agent and account for 1.5%, catalyst and account for 1.5%, basalt fibre and account for 1%, reclaimed rubber and rubber powder
Account for 14%.
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, aliphatic acid, ash content, sugar
The composition of class is 9%~6%.
Further, the thermoplastic elastomer (TPE) is artificial rubber or synthetic rubber.
Further, the tackifier are modified rosin resin.
Further, the plasticizer is citric acid ester type, epoxidized soybean oil plasticiser.
Further, the antioxidant is BHA, BHT or PG.
Further, the crosslinking agent is cross-linking radiation.
In sum, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
First, again be proportionally added into ground rubber by the present invention, and freshly prepared other component ratios of laying equal stress on can not only 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 the present invention is made
The rubber powder of work is coated in the outer layer of tire by fusing, and can play prevents inner tire layer to be punctured, and causes gas leakage or tyre break,
The problem of security incident is caused, and anticorrosive, high-temperature resistant result is good and environmental pollution is small；
2nd, the present invention uses tackifier, for reducing viscosity, raising when thermoplastic elastomer (TPE) is heated by viscosity, bonding
Intensity, the heat resisting temperature of regulation hot-melt adhesive powder and open assembly time, improvement 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
Being run at high speed in low temperature can be self-styled after not departing from and being punctured by sharp object and steel nail puncture or bullet；
4th, the crosslinking 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.
