Abstract
The invention relates to the technical field of rubber and particularly relates to a rubber composition for a tire shoulder pad. The rubber composition is characterized by being prepared from the following raw materials in parts by weight: 15-25 parts of butadiene rubber, 10-20 parts of natural rubber, 4-5 parts of zinc oxide, 10-12 parts of carbon black, 4-5 parts of silicon dioxide, 2-3 parts of isoprene, 0.1-0.3 part of an anti-scorching agent, 1-3 parts of stearic acid, 2-3 parts of microcrystalline wax, 3-5 parts of a plasticizer and 1-2 parts of sulfur. According to the rubber composition for tire shoulder pad, the themogenesis and hysteresis loss of rubber on a bottom layer of a tire tread can be effectively prevented, a shoulder vacancy problem in the use of the tire is reduced, and the use performance of the tire is improved.
Description
Technical field
The present invention relates to field of rubber technology, be specifically related to a kind of Tire shoulder pad rubber composition.
Background technology
Rubber, has the strong flexible polymer material of reversible deformation.Comparatively large deformation can be produced, resilient after removing external force under very little External Force Acting.Rubber belongs to complete amorphous polymer, and its second-order transition temperature is low, and molecular weight is often very large, is greater than hundreds of thousands of.Rubber extracts the condensed milk 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 in life.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.
As everyone knows, heavy load radial tire has the advantages such as wear-resisting, fuel-economizing, long service life, its superior performance is subject to the favor of consumers in general day by day, by finding domestic heavy load radial tire market survey, the empty problem of wheel tire shoulder is outstanding problem in current heavy load radial tire use procedure, and it is relevant with the thermogenesis performance of tyre shoulder wedge sizing material to take on empty problem.
Summary of the invention
The present invention, in order to overcome the shortcoming of prior art, provides a kind of Tire shoulder pad rubber composition.
Technical scheme of the present invention is: a kind of Tire shoulder pad rubber composition, is prepared from by the raw material of following parts by weight: cis-1,4-polybutadiene rubber 15-25 part, natural rubber 10-20 part, zinc oxide 4-5 part, carbon black 10-12 part, silicon-dioxide 4-5 part, isoprene 2-3 part, scorch retarder 0.1-0.3 part, stearic acid 1-3 part, Microcrystalline Wax 2-3 part, softening agent 3-5 part, sulphur 1-2 part.
Cis-1,4-polybutadiene rubber: cis-1，4-polybutadiene rubber by name entirely, be called for short BR, its molecular formula is (C
4h
6) n, belong to mixture.Advantages such as there is good springiness, wear resistance is strong, resistance to low temperature good, heat-dissipating is low, hysteresis loss is little, resistance to immunity in the wrong, resistance to cracking and dynamic property are good.
Natural rubber: our said natural rubber usually, refers to the natural rubber latex gathered from Para rubber tree, the elasticity decorating film made through the manufacturing procedure such as supersolidification, drying.The natural high moleculer eompound of natural rubber to be a kind of with polyisoprene be main component, molecular formula is (C
5h
8) n, its rubber hydrocarbon (polyisoprene) content, more than 90%, also grades containing a small amount of protein, lipid acid, sugar and ash.The physical property of natural rubber, has higher elasticity at normal temperatures, is slightly with plasticity, have extraordinary physical strength, hysteresis loss is little, and when being repeatedly out of shape, heat-dissipating is low, therefore its resistance to immunity in the wrong is also fine, and because be non-polar rubber, so electric edge performance is fine.
Carbon black of the present invention is preferably N375, N660.
Sulphur of the present invention is insoluble sulfur IS-7020.
Scorch retarder of the present invention is N-cyclohexyl thiophthalimide.
Beneficial effect: the present invention effectively can prevent the early stage ditch of groove from splitting, improving the wear resistance of tire tread, tear resistance and anti-collapsing and use up block performance, improves the life cycle of tire.
