Abstract
The invention discloses an anti-flex cold-resistant conveyor belt rubber material. The anti-flex cold-resistant conveyor belt rubber material is characterized by being prepared from the following raw material components in parts by weight: 80-100 parts of natural rubber NR, 8-12 parts of carbon fibers, 1-2 parts of zinc oxide, 0.8-1 part of stearic acid, 4-5 parts of silane coupling agent Si-69, 0.6-0.8 part of vulcanization accelerator DM, 5-8 parts of sulfur, 3-4 parts of epoxidized soybean oil, 0.3-0.5 part of dioctyl adipate, 1-2 parts of anti-aging agent 4010NA, 2-3 parts of nano talcum powder, 0.5-0.7 part of azodicarbonamide, 2-3 parts of peroxide and 6-10 parts of fortifier. The rubber material is improved in cold resistance, and meanwhile, great in tensile strength and elongation at break, and excellent in fatigability. The conveyor belt prepared from the rubber material has the characteristics of aging resistance and wear resistance; the properties such as flex resistance and low-temperature resistance of the large engineering conveyor belt can be improved, and the service life of the conveyor belt can be prolonged.
Description
Technical field
The invention belongs to conveying belt technical field of rubber material, be specifically related to a kind of anti-subdue cold-resistant conveying belt sizing material.
Background technology
Natural rubber has higher elasticity at normal temperatures, is slightly with plasticity, and have extraordinary physical strength, hysteresis loss is little, and when being repeatedly out of shape, heat-dissipating is low, and therefore its flexible resistance is also fine, and because be non-polar rubber, so electrical insulation capability is good.
Natural rubber is the material that a kind of chemical reaction ability is stronger, light, heat, ozone, radiation, subdue distortion and the metal such as copper, manganese can promote the aging of rubber, not ageing-resistant is the deadly defect of natural rubber, but, with the addition of the natural rubber of anti-aging agent, sometimes tan by the sun in the sun and still do not see much changes in two months, store in warehouse after 3 years and still can as usual use.
Natural rubber has good alkaline resistance properties, but not resistance to dense strong acid.Because natural rubber is non-polar rubber, can only more resistance to polar solvents, then swelling in non-polar solvent, therefore, its oil-proofness and solvent resistance very poor, in general, hydrocarbon, halohydrocarbon, dithiocarbonic anhydride, ether, higher ketone and higher fatty acid all have solvency action to natural rubber, but its solubleness is then by the impact of the degree of plasticating, lower ketones, lower member ester and alcohols are then non-solvents to natural rubber.
In the use procedure of rubber item, due to the needs of Working environment under some working condition, except requiring to have except excellent oil-proofness, also require that there is extraordinary low temperature cold tolerance and low compression set performance.If low temperature winter hardiness and compression set performance bad, the use properties of goods will be affected.
The handling characteristics of engineering machinery conveying belt is that space enrironment is severe, working conditions is harsh, lifting capacity is large.Therefore require conveying belt sizing material antifatigue, wear-resisting, be out of shape little, heat-dissipating is low.Conventional raising engineering machinery conveying belt colloidality can method change packing variety as change carbon black kind, add a small amount of white carbon black and staple fibre, optimize vulcanization system etc.Filling softening agent in a large number to improve low-temperature performance simultaneously, causing processibility bad, also easily causing the fillers dispersed in rubber uneven, physical and mechanical properties is unstable and compression set is poor.
Summary of the invention
The object of the present invention is to provide and a kind of anti-subdue cold-resistant conveying belt sizing material, the elastomeric material excellent combination property obtained, quality stability is good, significantly improve heavy construction conveying belt resistance toly to subdue, the performance such as low temperature resistant, extend the work-ing life of conveying belt.
The technical scheme that the present invention takes is:
A kind of resisting subdues cold-resistant conveying belt sizing material, and it is characterized in that, feed components is composed as follows according to weight part:
Natural rubber 80-100 part, carbon fiber 8-12 part, zinc oxide 1-2 part, stearic acid 0.8-1 part, silane coupling agent Si-69 4-5 part, sulfuration promote DM0.6-0.8 part, sulphur 5-8 part, epoxy soybean oil 3-4 part, Octyl adipate 0.3-0.5 part, antioxidant 4010NA 1-2 part, nanomete talc powder 2-3 part, Cellmic C 121 0.5-0.7 part, peroxidase 12-3 parts, strengthening agent 6-10 part.
Above-mentioned superoxide is 2,5-dimethyl-2,5-di-t-butyl peroxyhexane or two tert-butyl peroxy isopropyl benzene.
Above-mentioned strengthening agent is the mixture that CTAB specific surface area is greater than the carbon black of 80m2/g and White Carbon black and forms according to 2:1.
Beneficial effect of the present invention is:
The elastomeric material winter hardiness that the present invention obtains is improved, and tensile strength and tensile yield are also comparatively large simultaneously, and fatigability is fine.Obtained conveying belt has ageing-resistant, anti abrasive feature, can significantly improve heavy construction conveying belt resistance toly to subdue, the performance such as low temperature resistant, extend the work-ing life of conveying belt.
