Description

A kind of environmental protecting tyre tube and preparation method

Technical field

The invention belongs to a kind of inner tube of vehicle tyre, particularly relate to a kind of environmental protecting tyre tube and the preparation method that are used for inner tube of tyre for motor-vehicle.

Background technology

Tire is the important component part of self-propelled vehicle, and the inner tube of a tyre is the component part of tire, along with the development people of society increase day by day to the demand of self-propelled vehicle, thereby the requirement to tire is also just higher, the automobile-used rubber inner tube of current mobility is to be batching commonly used with carbon black, not only cost height but also carbon black have also caused pollution to environment, simultaneously the healthy of production work personnel also is harmful to, the air-tightness of the inner tube of a tyre of employing production of carbon black is also relatively poor, so need to replace with a kind of later-model material the application of carbon black.Promptly use the major defect of the rubber inner tube of production of carbon black: productive costs height, contaminated environment; Harmful to the worker personnel health; The air-tightness of the inner tube of a tyre is relatively poor.

Summary of the invention

The object of the invention is that the problem that is produced for batching commonly used with carbon black in the rubber inner tube is produced in solution at present, and provides a kind of cost low, and is pollution-free, environmental protecting tyre tube that air-tightness is good and preparation method.

The present invention is for solving the deficiency that prior art exists, the technical scheme of being taked is: a kind of environmental protecting tyre tube, main reclaimed rubber, natural gum, goeschwitzite and the additive of adopting, make through banburying, after filtering, make base, docking, the raw material that makes the inner tube of a tyre adopts following component in percentage by weight to form, reclaimed rubber 17%～80%, natural gum 7%～46.5%, goeschwitzite 10%～30%, titanate coupling agent 0.5%, vulcanizator 0.5%～1%, accelerator 0.5%～2%, aging inhibitor 0.5%～1%, zinc oxide 1%～2%.

Described natural gum is for making natural gum commonly used in the tire; Described reclaimed rubber is to make with junked tire, and rationally utilizing again of junked tire provides cost savings greatly, and more than reclaimed rubber intensity 10 MPas, percentage elongation is more than 39%, more than fineness 60 orders, and Mooney viscosity 50～70.

Described goeschwitzite is a hydromuscovite, hydromuscovite stone is broken into 1000 purpose hydromuscovite powder with centrifugal wind formula pulper, the model of titanate coupling agent is commercially available OL999, goeschwitzite and titanate coupling agent are the application that has substituted carbon black as rubber reinforcing filler, played the effect that increases rubbery intensity, the hydromuscovite powder is a schistose texture, thereby the inner tube of a tyre air-tightness that makes is good, and titanate coupling agent has played the effect that promotes reinforcing property in reinforcing agent.

Described vulcanizator is 200 a purposes sulfuration powder; Described accelerator is an accelerant CZ; Described aging inhibitor model is RD, BLE or 4010NA; Described zinc oxide is the commercially available prod; Vulcanizator, accelerator and zinc oxide are the vulcanizing system auxiliary agent, and aging inhibitor is the protection system auxiliary agent.

A kind of environmental protecting tyre tube of the present invention and preparation method are:

Step 1: get natural gum 7%～46.5%, reclaimed rubber 17%～80%, goeschwitzite 10%～30%, titanate coupling agent 0.5%, vulcanizator 0.5%～1%, accelerator 0.5%～2%, aging inhibitor 0.5%～1%, zinc oxide 1%～2%, standby;

Step 2: earlier natural gum 7%～46.5% and reclaimed rubber 17%～80% are dropped in the 75L banburying container, temperature is controlled at 90 ℃, banburying 3～4 minutes; Drop into accelerator 0.5%～2%, aging inhibitor 0.5%～1% and zinc oxide 1%～2% then, temperature is controlled at 95 ℃, banburying 3 minutes; Drop into goeschwitzite 10%～30% and titanate coupling agent 0.5% at last, temperature is controlled at 100～110 ℃, and banburying 7～9 minutes is controlled at temperature below 165 ℃ at last, carries out binder removal;

Step 3: adopt 40 orders and 60 order filtering nets, two-layer about being divided into, the glue that step 2 is made filters;

Step 4: the glue after will filtering is parked more than 8 hours at normal temperatures, and is standby;

Step 5: the glue that step 4 makes is put into mill, and temperature is controlled at below 120 ℃, adds vulcanizator 0.5%～1% then, mixes, and is standby;

Step 6: get the glue that step 5 makes, put into extruder, body temperature 60 degree head temperatures 70～80 degree of extruder are made the tire bucket;

Step 7: with tire bucket fixed length, by dress valve and joint, after the tire bucket is parked 24 minutes～24 hours at normal temperatures;

Step 8: the tire bucket that step 7 makes is put into vulcanizer, vulcanized 2～3 minutes, saturated vapour pressure 0.7～0.75 MPa makes environmental protecting tyre tube.

The mixing of described step 5 is meant that the manual glue that mill is produced is cut off and falls in the pallet, to fall into glue in the pallet again puts into mill and opens refining once, and then the glue that will open refining is cut off and is dropped into pallet, upset wrestles twice about then the glue in the pallet being carried out by hand, after mixing like this, colloid is more even.

The diameter of described extruder is decided according to demand, body temperature 60 degree head temperatures 70～80 degree of extruder, and the tire bucket size of extruding like this is more stable.

Beneficial effect:

Adopting junked tire to make reclaimed rubber is to reduce the resource energy consumption, reduces the pollution to environment, and a low big behave reduces production costs; The pollution of preparation carbon black is more serious, and cost is than higher, for this reason, the technological means that the present invention adopts mainly is in the inner tube of a tyre of preparation, its raw material does not use carbon black, is that primary raw material combines with natural gum and goeschwitzite with the reclaimed rubber, and the product design performance that makes is good, so significantly reduced productive costs, reduced environmental pollution; Useful to workers health on production process; Because the hydromuscovite powder is a schistose texture in reinforcing agent, make the air-tightness of the inner tube of a tyre better, and the cost of hydromuscovite powder is low; Used reinforcing agent to replace carbon black, the application of titanate coupling agent has promoted reinforcing property, does not have difference with the product of having used carbon black on the intensity, even than better on the intensity of equal quality.
