Abstract
The invention discloses a method for manufacturing a heat-resistant conveyor belt. The method is characterized by comprising the following steps: (1) plasticizing butadiene rubber and ethylene propylene terpolymer; (2) adding an anti-aging agent, nano zinc oxide and stearic acid for mixing; (3) adding an accelerant, tackifying resin PN-110 and sulfur for reacting; and (4) adding carbon black, dicumyl peroxide, polybutylene and dedicated paraffin hydrocarbon oil, mixing and discharging. The conveyor belt obtained by using a high-quality and reasonable formula and accurate process indexes has good high temperature resistance, excellent super abrasion resistance, tensile strength and elasticity, long service life and low operating cost.
Description
Technical field
The invention belongs to conveyor belt material technical field, be specifically related to a kind of manufacture method of heat resistance conveyor belt.
Background technology
Cis-1,4-polybutadiene rubber is that divinyl obtains through solution polymerization, and cis-1,4-polybutadiene rubber has winter hardiness excellent especially, wear resistance and elasticity, also has good ageing-resistant performance.The cis-1,4-polybutadiene rubber overwhelming majority is for the production of tire, and small part is for the manufacture of cold-resistant goods, cushioning material and adhesive tape, rubber overshoes etc.The shortcoming of cis-1,4-polybutadiene rubber is that tear resistance is poor, and wet-sliding resistant performance is bad.
Terpolymer EP rubber is the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon, and topmost characteristic is exactly its superior resistance to oxidation, ozone-resistant and erosion-resistant ability.There is fabulous vulcanization characteristics, it can absorb a large amount of fillers and oil and influencing characteristic is little.Therefore can the cheap rubber compound of cost of manufacture.
The course of processing of rubber comprise plasticate, mixing, roll or extrude, the basic working procedure such as shaping and sulfuration, each operation has different requirements for goods, coordinates respectively with some non-productive operations.In order to add in rubber by various required Synergist S-421 95, first rubber needs to improve its plasticity through over-mastication; Then by mixing, carbon black and various rubber ingredients and rubber are uniformly mixed into sizing material; Sizing material makes definite shape blank through extrusion; Eventually pass sulfuration and again the work in-process with plasticity are made elastomeric the finished product.
Conveying belt has different functions according to required Working environment, the conveying belt used in steel mill, cement mill or coke-oven plant, and because it often works in an environment of high temperature, therefore conveying belt must have resistant to elevated temperatures characteristic.Present conveying belt is mainly due to used elastomeric material non-refractory, thus the resistant to elevated temperatures effect of the conveying belt that market produces and uses is poor, and during this type of conveying belt uses, the life-span is shorter, easily causes the financial loss of enterprise.
Conveying belt in operation process by the effect of material, with Long contact time, the friction of conveyer carrying roller, material, cause conveyer belt coating rubber not wear-resisting, easily come off, cause maintenance frequent, the life-span is short.Thus running cost is higher, extends conveying belt significant for work-ing life.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of heat resistance conveyor belt, make the conveying belt obtained have excellent properties that is high temperature resistant, rub resistance, running cost is low, and the life-span is long.
The technical scheme that the present invention takes is:
A manufacture method for heat resistance conveyor belt, is characterized in that, comprises the steps:
(1) first by cis-1,4-polybutadiene rubber and the terpolymer EP rubber ratio according to 2:1, to plasticate 75-80s controlling rotating speed 48-50r/min in two roller mill;
(2) anti-aging agent 1-2%, nano zine oxide 0.3-0.6% and the mixing 65-75s of stearic acid 2-3% that antioxidant MB and antioxidant MC form according to 1:1 is added;
(3) mixture 0.8-1% that accelerant CZ and accelerant NOBS form according to 3:1 is added again and tackifying resin PN-110 3-4%, sulphur 5-6% react 85-95s at 60-80 DEG C;
(4) carbon black 3-4%, dicumyl peroxide 0.5-0.6%, polybutene 5-7% and special paraffin hydrocarbon ils 3-4%, mixing 80-85s is added again, discharge when temperature is 125-130 DEG C.
Beneficial effect of the present invention is:
The present invention selects high-quality, reasonably fills a prescription, and the conveying belt obtained by accurate technic index has good high thermal resistance, and super wear resistance, to break brute force and elasticity excellent, and conveying belt extends work-ing life, and running cost reduces.
