Abstract
The invention relates to the technical field of tires, in particular to a rubber wear-resisting tire tread. The rubber wear-resisting tire tread is characterized by being prepared from the following raw materials in parts by weight: 26-30 parts of butadiene rubber, 26-30 parts of natural rubber, 5-7 parts of organic fiber, 4-5 parts of zinc oxide, 10-12 parts of carbon black, 4-5 parts of silicon dioxide, 2-3 parts of isoprene, 2-3 parts of microcrystalline wax, 3-5 parts of a plasticizer and 1-2 parts of sulphur. According to the rubber wear-resisting tire tread, the early groove crack of a tread groove can be effectively prevented; the abrasive resistance, the tear resistance and the anti-cracking and anti-dropping properties of the tire tread are improved; and the service cycle of the tire is prolonged.
Description
Technical field
The present invention relates to tire production technical field, be specifically related to a kind of rubber wear-resisting tire tread.
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 the doughnut of automobile important component part, be that automobile bears gravity, transmitting tractive power, damping force, steering force and bears the vitals of road surface reaction, its quality, is directly involved in personal safety as well as the property safety.At present in Scrap tire, the both sides of most tire are almost intact, are exactly because tire tread wear is serious, in order to traffic safety, and abandon using, fallen like this by a large amount of expense.
Summary of the invention
The present invention, in order to overcome the shortcoming of prior art, provides a kind of rubber wear-resisting tire tread.
Technical scheme of the present invention is: a kind of rubber wear-resisting tire tread, is prepared from by the raw material of following parts by weight: cis-1,4-polybutadiene rubber 26-30 part, natural rubber 26-30 part, organic fibre 5-7 part, zinc oxide 4-5 part, carbon black 10-12 part, silicon-dioxide 4-5 part, isoprene 2-3 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.
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.
