Technical field

The present invention relates to a kind of microwave radiation renovation process of environment-friendly, high-intensity power shoddy, belong to the regenerating waste or used rubber field.Be applicable to that the crown with tread rubber of lorry tyre by resin prepares the environmental friendly regenerated of rubber powder.

Background technology

The quantity of waste old material is only second to plastic waste in spent high molecular material, wherein learies is more than 1,000,000,000 doughnut whole world year, and China is at 5000~6,000 ten thousand.The recycling of waste old is main with junked tire, and other also comprises the waste and old rubber overshoes and the inner tube of a tyre etc., and the utilization of waste rubber helps protecting environment, realizes the utilization again of resource, helps continuous development of society economy.

Conventional regeneration glue need carry out in regenerating tank in regenerative process at present, needs operations such as heated and stirred, cleaning, dehydration, refining, and equipment and operation are complicated, and investment is big.In regenerative process; More a large amount of tenderizer coal tar, Stockholm tar, oil extractum etc. have been added; Make shoddy have very niff; Bigger contaminative also contains a lot of carcinogenic chemical substances of the poisonous people of making, and developed countries such as present Europe have limited the outlet of the rubber items such as tire that contain these chemical substances.Present reclaiming process time of conventional regeneration glue, generally about 4h, vapor pressure was at 1MP aAbout, the time is long, and efficient is low.The tensile strength of conventional regeneration glue is lower, generally at 5~8MPa.

Summary of the invention

The present invention provides a kind of microwave radiation renovation process of environment-friendly, high-intensity power shoddy, utilizes microwave radiation technology that shoddy is regenerated and obtains environment-friendly, high-intensity power shoddy.

The present invention realizes with following technical scheme: a kind of microwave radiation renovation process of environment-friendly, high-intensity power shoddy, and the rubber powder for preparing with truck tyre crown glue is a raw material, adds various Synergist S-421 95 processing and preparing, the mass parts of described rubber powder and each Synergist S-421 95 is:

Load-carrying tire crown prepares 100.00 parts of 20 order rubber powders

12.00 parts of tenderizer rosin

0.40 part of regenerator kautschin;

Concrete preparation process is following:

(1) crown glue preparation 10~30 order rubber powders of screening truck tyre;

(2) drying is the good above-mentioned thick rubber powder of 10~30 purposes and tenderizer rosin, regenerator kautschin are mixed with modified glue powder in proportion, and the paving thickness of rubber powder is controlled at 2cm or below the 2cm;

(3) with modified glue powder at radiation frequency 2450Hz, microwave radiation 1min 40s carries out micro wave regeneration under the microwave irradiation power of 800W;

(4) sizing material behind the micro wave regeneration is cooled to below 45 ℃ at once;

(5) will cool off sizing material that good micro wave regeneration crosses and render to and carry out refining 20min in the mill, refining temperature generally is controlled at 35~50 ℃, the film any surface finish that refining is good, and color and quality are even;

(6) according to the National Standard regenerated rubber " GB/T 13460-2008 shoddy test formulations successively with various Synergist S-421 95s join carry out in the shoddy mixing; Then rubber unvulcanizate is vulcanized; After parking 24h, sizing material is carried out the test of physical and mechanical properties and process industrial art performance.

The performance test results shows that the tensile strength of shoddy reaches more than the 18MPa, and elongation at break is 400%, and the Wei Shi plasticity number is 0.35~0.45.

The invention has the beneficial effects as follows: the microwave radiation renovation process of environment-friendly, high-intensity power shoddy had both protected molecular backbone chain not to be destroyed; Can guarantee the cross-link bond fracture again; With environmental friendliness; Conserve energy is compared with traditional waste old high temperature regeneration method and greatly have been improved production efficiency, and production efficiency improves 5 times than traditional method.Microwave obtains environment-friendly type regeneration glue down and compares with conventional regeneration glue, and mechanical property does not reduce, but the recovery time is short, and regeneration temperature is low, has kept the performance that reclaims rubber, has outstanding economic benefit and social benefit.
