Description
Technical field
The invention belongs to rubber product technical field, be specifically related to a kind of wear-resistant cycloconveyor belt calendering sizing compound.
Background technology
Extract the latex of the plant such as rubber tree, russian dandelion, the material with elasticity, insulativity, waterproof and air made after processing.Elastomeric macromolecular compound.Be divided into natural rubber and synthetic rubber two kinds.Natural rubber from the plant such as rubber tree, russian dandelion, extracts colloid post-treatment make; Synthetic rubber is then obtained through polyreaction by various monomer.Rubber item is widely used in industry or life each side.
Styrene-butadiene rubber(SBR), is called for short SBR, by divinyl and styrene copolymerized obtained.SBR of emulsion polymerization and solution polymerization styrene-butadiene rubber is divided into by production method.Its over-all properties and chemical stability good.Cis-1,4-polybutadiene rubber, cis-1，4-polybutadiene rubber by name, is called for short BR, is obtained by polymerizing butadiene entirely.With other general purpose rubber ratios, the winter hardiness of the cis-1,4-polybutadiene rubber after sulfuration, wear resistance and elasticity are excellent especially, and under dynamic load, heating is few, and ageing-resistant performance is good, easily and natural rubber, chloroprene rubber, paracril etc. use.
Conveying belt is for working the rubber and fiber, the metal composite goods that carry and transport material effect in belt conveyor, or the goods of plastics and fabric compound.Conveying belt is widely used in the occasion that in the industries such as cement, coking, metallurgy, chemical industry, iron and steel, fed distance is shorter, operational throughput is less.Rotary conveyor is widely used in the various solid block of conveying and powder shape material or work piece in agricultural, industrial and mining enterprises and transportation, the serialization of conveying belt energy, high-level efficiency, high-inclination conveying, conveying belt operational safety, conveying belt is easy to use, easily, freight charges are cheap, and can shorten shipment distance in maintenance, reduce construction costs, use manpower and material resources sparingly.
Anti-tear, antiwear conveying belt is widely used in the operation transport of the mineral aggregates such as mine iron ore, copper mine, stone ore.In recent years, China's economy increases fast, and supply falls short of demand for the Mineral resources of domestic-developed, and this has driven the large scale mining of mine resources (iron ore, copper mine, stone ore etc.) to utilize.Adopt the conveying belt of current explained hereafter very low for work-ing life, therefore, the operation conveying requirement of mineral aggregate cannot be met.Easily there is incipient scorch phenomenon in common sizing material in actual use, and the unfairness of calendering cord.This just require rolling process produce sizing material of belt should have compared with high Mooney viscosity with the planarization of satisfied calendering cord and very property, there is longer Mooney scorch time to meet calendering procedure processing safety simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of wear-resistant cycloconveyor belt calendering sizing compound, bond strength is high, bonds conservation rate high after thermal ageing, has excellent anti-tear performance simultaneously, excellent wear resisting property, and the work-ing life of conveying belt extends.
The technical scheme that the present invention takes is:
A kind of wear-resistant cycloconveyor belt calendering sizing compound, is characterized in that, formulated by following raw materials in parts by weight:
Styrene-butadiene rubber(SBR) 25-35 part, cis-1,4-polybutadiene rubber 15-20 part, aramid fiber short fibre 5-7 part, vulcanizing agent 5-6 part, the N-tertiary butyl-2-benzothiazolyl sulphenamide 0.8-1 part, hexa methoxy methyl melamine 3-4 part, zinc oxide 2-4 part, hydrated SiO 2 1-2 part, stearic acid 2-3 part, carbon black N326 8-10 part, N-cyclohexylthiophthalimide 1.2-1.5 part, silane coupling agent WD-40 1.5-2 part, auxiliary agent 1-2 part.
Above-mentioned vulcanizing agent is the mixture that Sulfur IS-7020 and dithiodimorpholine form according to 3:1.
Above-mentioned auxiliary agent is the mixture that paraffin and aromatic hydrocarbon oil form according to 1:2.
Beneficial effect of the present invention is:
The present invention, by the proportion relation between each material of adjustment system, improves the degree of adhesion of sizing material; Aramid fiber short fibre brute force is high, is subject to the impact not easy fracture of bulk mineral aggregate, has high tear-resistant performance.Bond conservation rate after the conveying belt sizing material thermal ageing that the present invention obtains high, there will not be the problem of tree lace delamination, use safety.
