Abstract
The invention discloses a cold-resistant rubber clad material used for a roller of a conveyor. The cold-resistant rubber clad material used for the roller of the conveyor is characterized by being prepared from the following components in parts by weight: 70-80 parts of natural rubber, 15-25 parts of silicone rubber, 5-9 parts of ethylene propylene rubber, 1-3 parts of vulcanizing agent, 0.4-0.8 part of accelerant, 2-4 parts of zinc oxide, 0.8-1.5 parts of stearic acid, 1.5-3.5 parts of anti-aging agent RD, 30-40 parts of carbon black, 2-5 parts of white carbon black, 5-10 parts of dioctyl phthalate and 10-28 parts of clay. The cold-resistant rubber clad material used for the roller of the conveyor is prepared from natural rubber and silicon rubber (which are taken as base rubber), as well as a small amount of ethylene propylene rubber; the cold-resistant rubber clad material used for the roller of the conveyor has good cold-resistant property and is applicable to continuous and persistent use at a low temperature; meanwhile, the cold-resistant rubber clad material used for the roller of the conveyor also has the advantages of high tensile strength, fire resistance, high-temperature resistance and corrosion resistance.
Description
Technical field
The invention belongs to rubber materials, specifically a kind of conveyer carrying roller arctic rubber coating material.
Background technology
The winter hardiness of rubber keeps the ability of elasticity and normal work under the low temperature of regulation.At low temperatures, because relaxation sharply slows down, hardness, modulus and molecule internal friction increase vulcanized rubber, and elasticity significantly reduces, and cause the work capacity of rubber item to decline, particularly particularly outstanding under dynamic condition.The general rubber using at low temperatures, except low-temperature performance, also requires other performances, and therefore such as oil resistant, media-resistant etc. select merely the rubber that winter hardiness is good often can not practical requirement, at this moment will consider and use.The transfer roller of domestic production at present can not use with General Purpose Rubber carrying roller under low-temperature condition; because the carrying roller of General Purpose Rubber coating layer is under low temperature environment; rubber layer can be gradually soon loose, follow the string and stress; hardening, become fragile, physicochemical property declines to a great extent, and becomes vitrifying state; the ability so that embrittlement is lost the job; directly affect work-ing life and value, thereby by forced-stopping machine roll change, cause huge financial loss.
Summary of the invention
The object of the invention is to prior art defect, a kind of conveyer carrying roller arctic rubber coating material is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of conveyer carrying roller arctic rubber coating material, it is characterized in that, described arctic rubber coating material is made up of the component of following weight part: natural rubber 70-80 part, silicon rubber 15-25 part, ethylene-propylene rubber(EPR) 5-9 part, vulcanizing agent 1-3 part, promotor 0.4-0.8 part, zinc oxide 2-4 part, stearic acid 0.8-1.5 part, anti-aging agent RD 1.5-3.5 part, carbon black 30-40 part, white carbon black 2-5 part, dioctyl phthalate (DOP) 5-10 part, potter's clay 10-28 part.
Described arctic rubber coating material is made up of the component of following weight part: 75 parts of natural rubbers, 20 parts, silicon rubber, 7 parts, ethylene-propylene rubber(EPR), 2 parts of vulcanizing agents, 0.6 part of promotor, 3 parts, zinc oxide, 1.2 parts of stearic acid, 2.5 parts of anti-aging agent RDs, 35 parts of carbon blacks, 3.5 parts of white carbon blacks, 8 parts of dioctyl phthalate (DOP)s, 18 parts, potter's clay.
Described vulcanizing agent is sulphur.
Described promotor is dithio-bis-benzothiazole.
Beneficial effect of the present invention: it is main rubber that arctic rubber coating material of the present invention is selected natural rubber, silicon rubber, add a small amount of ethylene-propylene rubber(EPR) to prepare, arctic rubber coating material of the present invention has good cold tolerance, be applicable to the use of persistence continuously under cold condition, this rubber advantage such as also to have tensile strength high, fire-resistant, high temperature resistant, corrosion-resistant simultaneously.
