Abstract
A two-stage mixing process for rubber comprises first mixing of raw rubber and compounding agent and second mixing of the product obtained from first mixing and regenerated rubber. Obtained rubber can be used as tyre, hose, conveying belt, shoe and plate. Said process features high productivity and saving energy.
Description
The invention belongs to the rubber processing field, directly relate to rubber two-stage mixing process.
At present, mainly there are three kinds of rubber mixing-milling techniques in the rubber industry, has: milling maternal rubber technology, one section calendering process of rubber, rubber two-stage mixing process.Wherein milling maternal rubber technology has good dispersion, advantage that the powder loss late is low, but also exists the shortcoming that the process-cycle is long, power consumption is high, operation is loaded down with trivial details simultaneously.The advantage of one section calendering process of rubber be exactly with short production cycle, technical process is simple, but also exists the relatively poor drawback of melting effect.For solve the cycle that milling maternal rubber technology exists long, power consumption is high, operation is loaded down with trivial details and the problem of the melting effect difference that one section calendering process of rubber exists, many producers have adopted rubber two-stage mixing process now.Rubber two-stage mixing shortens the process-cycle more than 1/3rd than milling maternal rubber technology, and the while is corresponding the cutting down the consumption of energy along with the shortening in cycle also, and technical process is simplified relatively; Rubber two-stage mixing process is better than one section calendering process effect, and the physical property of its vulcanized rubber improves 10～20%.Though rubber two-stage mixing has above-mentioned advantage,, bring the process-cycle to be higher than the problem of one section mixing process time again owing to adopted two step process.
Purpose of the present invention is exactly that a kind of new rubber two-stage mixing process will be provided, and it can overcome the drawback that the process-cycle that has the rubber two-stage mixing process existence now is higher than one section calendering process effectively, and energy consumption is significantly reduced.
The objective of the invention is this auspicious realization, at first rubber, compounding ingredient carry out one section mixing, elastomeric compound is parked then, reclaimed rubber with park after one section elastomeric compound carry out two-stage mixing again.
Rubber two-stage mixing process of the present invention is compared with traditional two-stage mixing process, the tire production producer of 100,000,000 yuan of scales of annual value of production, surplus the annual overall economic efficiency 60 ten thousand yuan.Elastomeric compound combination property by explained hereafter of the present invention is compared with the elastomeric compound of traditional two-stage mixing process production and since reclaimed rubber have neither part nor lot in one section mixing, reduced the mechanical damage of strand, thereby improved the tensile property of sizing material.The present invention has overcome traditional two-stage mixing process and has hindered the drawback that rubber combines with compounding ingredient at the reclaimed rubber that one section operation upslide reclaimed rubber exists, thereby shortened mixing cycle owing to adopted the technology of throwing reclaimed rubber in the two-stage mixing process.
Fig. 1 is traditional rubber two-stage mixing process flow chart.
Fig. 2 is a rubber two-stage mixing process flow chart of the present invention.
Further specify with regard to detailed process of the present invention below in conjunction with accompanying drawing.
In Fig. 1, rubber, compounding ingredient, reclaimed rubber enter one section and mix Refining was parked 4～24 hours then, entered two-stage mixing again. Among Fig. 2, rubber, compounding ingredient at first carry out one section mixing, stop then Put 4～24 hours, and carried out two-stage mixing with reclaimed rubber again.
Be implementation of processes example of the present invention below:
The natural broken-down rubber of 18kg, 12kg cis-butadiene cement are entered mixing with 0.18kg altax, 0.3kg accelerant CZ, 1.2kg zinc oxide, 0.9kg stearic acid, 0.3kg anti-aging agent RD, 0.3kg antioxidant 4010,0.3kg paraffin, the solid Malong of 2.4kg, 6kg701 carbon black, 15kg high abrasion carbon black, 4.5kg pine tar on banbury, get off after mixing 11 minutes and park.One section elastomeric compound of 30.885kg after parking, 13.5kg tread reclaimed rubber, 0.45kg Sulfur, 0.015kg promoter TT are entered two-stage mixing in mill, get off after mixing 7 minutes and park.
Claims (1)
1, a kind of rubber two-stage mixing process is characterized in that: rubber, compounding ingredient at first carry out one section mixing, elastomeric compound is parked then, reclaimed rubber with park after one section elastomeric compound carry out two-stage mixing again.
