Abstract
The invention discloses a method for preparing high-tensile-strength conveyor belt cover rubber. The method is characterized by comprising the following steps: (1) making a plasticated rubber; (2) first-stage mixing; (3) second-stage mixing; (4) rolling a belt billet; and (5) vulcanizing. The cover rubber prepared by the method has excellent tensile strength, heat resistance, and wear resistance, and the requirement of conveyed materials on tensile strength is met by adding nylon to roll the belt billet; carbon black and other components are used as a filling system to play an enhancing role and improve thermal oxidative aging resistance, so that the bonding transition effect is good, and thus the service life of a conveyor belt is greatly prolonged, and the good economic benefit is realized.
Description
Technical field
The invention belongs to conveyer belt sizing material manufacture technology field, be specifically related to a kind of preparation method of high tensile conveyer belt coating rubber.
Background technology
The independent kneading of rubber, claims to plasticate to improve for the purpose of its plasticity.The rubber of plasticating and compounding ingredient refine be collectively referred to as mixing.Elastomeric compound in calendering, extrude, die-filling before, for increasing plasticity further, improve homogeneous property and short its softens, close heating with mill refining and claim heat refining.For making the compounding ingredient in elastomeric compound fully disperse, claim refining by the little roll spacing thin-pass of mill.
Along with the raising of whole world expanding economy and industrial automation level, the application surface of conveyer belt becomes more and more wider, and demand is increasing, requires also more and more higher.Mine, chemical industry, coal, iron and steel, cement industry institute convey materials generally have megathermal feature, simultaneously for the consideration for conveyer belt service life, usually require that conveyer belt has good anti-wear performance.But current used domestic T2 rank heat resistance conveyor belt, only can meet the requirement to temperature, few to the consideration of the wearability concerning conveyer belt service life.
Conveying band joint face glue is also rubber cover, is a kind of sizing material of belt surface, conveyer belt in use often by material impact, wear and tear and the infringement such as to pierce through.So rubber cover has good hot strength and wearability (abrasion loss≤0.8cm3/1.61Km), ageing-resistant, resistance to bioerosion is the characteristic that rubber cover must have.Rubber cover also should have the processing performances such as good viscosity in addition.Based on natural rubber, be auxiliary with appropriate butadiene-styrene rubber, can make different thickness as required, conventional has 0.8-5mm thick.Stand in the angle of production and energy-saving and emission-reduction, the preparation method developing a kind of high tensile conveyer belt coating rubber just seems particularly necessary.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of preparation method of high tensile conveyer belt coating rubber, the rubber cover obtained has good hot strength, heat resistance, has again fine anti-wear performance.
The technical scheme that the present invention takes is:
A preparation method for high tensile conveyer belt coating rubber, is characterized in that, comprises the steps:
(1) broken-down rubber processed: get 60 parts, butadiene-styrene rubber, on a mill until, control roll is apart from 3-5mm, and temperature is 50-60 DEG C, and plasticate 15-20min for butadiene rubber 30 parts;
(2) one sections mixing: dropped into by broken-down rubber in banbury, add plasticizer 3-4 part, chlorosulfonated polyethylene 15-20 part, super abrasive carbon black N115 15-20 part, tetramethylthiuram disulfide 2-3 part, silane coupler SI-69 3-5 part, temperature controls at 120-130 DEG C of banburying 2-4min;
(3) two-stage mixing: then open floating weight and add octyl group phenolic aldehyde BN-1, N-(1 successively, 3-dimethylbutyl)-N'-diphenyl-para-phenylene diamine 2-3 part, stearic acid 1-3 part, sulphur 5-7 part, control temperature is 130-150 DEG C, banburying 3-5min, by thickness 8-12mm slice, park 15-17h;
(4) made-up belt is rolled: elastomeric compound added 4-5 layer nylon cloth before sulfuration, and calender carries out calendering made-up belt;
(5) sulfuration: the rubber after made-up belt is put into vulcanizer, control temperature is 147-150 DEG C, and pressure is 0.8-0.9MPa, sulfuration 8-10min.
Plasticizer in above-mentioned step (2) is the one in aromatic naphtha, carbon 5 Petropols, octyl group phenolic aldehyde BN-1 or octyl group phenolic aldehyde BN-2.
Beneficial effect of the present invention:
The present invention has good processing characteristics, obtained rubber cover has excellent hot strength, heatproof, anti-wear performance, by adding nylon calendering made-up belt, meet the requirement of convey materials to hot strength, the compositions such as carbon black, as infill system, can not only play the effect of enhancing, and its heatproof air aging performance can be carried, play and well bond transitional function, the service life of conveyer belt is significantly improved, achieves good economic benefit.
