Description
Technical field
The present invention relates to a kind of rubber, the regenerated butyl mixing rubber that especially a kind of high-speed vacuum tyre airtight layer is used.
The invention still further relates to the production method of a kind of high-speed vacuum tyre airtight layer with regenerated butyl mixing rubber.
Background technology
The develop rapidly of Domestic Automotive Industry, increasing to the demand of rubber tyre.Because the vacuum tire is all even better than conventional tyre on security, reliability, but also has characteristics in light weight, good heat dissipation, comprehensive cost is also low, therefore also obtains more and more people's approval.Along with the raising of China's road conditions and perfecting of vacuum tire adequate and systematic service facility, the vacuum tire will be more widely used.To guide Truck Market to step into " lightweight " and control a series of policies such as super, fuel oil tax, in " fuel-economizingization " epoch, the advantage of vacuum tire will be more obvious, and market potential will be excavated gradually, and popularizing the vacuum tire will be the megatrend of development.
The vacuum tire is compared conventional tire, because of its structure has following advantage: the one, it is slow to leak gas, and safe vacuum tire is pierced back gas leakage slowly, still can adhere to reaching the place under repair of repairing point; The conventional tyre inner tube of a tyre is full of gas rapidly after being pierced through by foreign matter between the inner tube of a tyre and cover tire, flat tire even moment can take place immediately might blow out.The 2nd, thermal diffusivity is good, life-span, long vacuum tire did not have the inner tube of a tyre and rim strip, the inner tube of a tyre and the tyre cavity frictional heat of tire have been reduced effectively, inner air directly contacts with wheel rim, heat also can directly distribute by wheel rim, the too high phenomenon of tyre temperature can not occur, can reduce and blow out, prolong tire work-ing life.The 3rd, weight reduction, oil consumption reduces owing to reduced the inner tube of a tyre and rim strip, the weight saving of tire, and the spare part of wheel rim has also reduced retainer, weight further alleviates, a whole set of tire all changes the vacuum tire into can light good hundreds of jin, and the running resistance of vacuum tire is less, can save 3% fuel oil, the travel deadweight and the minimizing of oil consumption are exactly extra profit concerning the truck driver.The 4th, wear-resisting, be fit to long-distance running at high speed in addition, the vacuum tire is more wear-resisting, and has better dynamic balance performance, and driver comfort also can improve, and therefore is more suitable for long-distance high speed and travels for a long time.
Summary of the invention
The purpose of this invention is to provide a kind of high-speed vacuum tyre airtight layer regenerated butyl mixing rubber, this rubber has that resistance to air loss is good, bond properties is good, feature that can covulcanization during tyre vulcanization.
The technical solution used in the present invention is:
A kind of high-speed vacuum tyre airtight layer regenerated butyl mixing rubber, its raw materials by weight is: vulcanized butyl rubber 45-60%; Halogenated butyl rubber 20-35%; Resin 5-10%; Tenderizer 1-5%.
Produce the processing method of high-speed vacuum tyre airtight layer with regenerated butyl mixing rubber, comprise that raw materials pretreatment, pulverizing, regeneration, compressing tablet, cooperation are mixing, filtration, concise and formed package, described technology regenerated step is: it is indoor that the rubber grain of weighing is poured into kneading, start the main frame rotary rotor and stir shearing, the indoor temperature of kneading remains on 200-250 ℃, and churning time was controlled at 25-40 minute.
Described rubber grain is vulcanized butyl rubber and halogenated butyl rubber, and described tenderizer is the paraffin wax softening oil, and described technology regenerated number of times is for once.
The invention has the advantages that: by the adjustment of prescription, proportioning, realization can be satisfied the bubble-tight requirement of vacuum tire, with natural rubber, synthetic rubber good bond properties is arranged, can covulcanization high-speed vacuum tyre airtight layer regenerated butyl mixing rubber during tyre vulcanization.
