Abstract
The invention discloses high-wear-resistant high-strength precured tread rubber for tyre retreading of a truck tyre. Raw materials weighed according to a weight ratio are mixed by an internal mixer to prepare a rubber compound; and the rubber compound undergoes tyre extrusion and vulcanization to prepare annular or strip-shaped precured tread rubber. The invention has the following advantages: wear resistance of a retreaded tyre for a truck is raised; service life of the tyre is prolonged; problems such as delaminating, swelling, blowout and the like due to excess temperature of the tyre during the using process are minimized; and use security of the retreaded tyre for a truck is raised.
Description
Technical field
The present invention relates to macromolecular material, specifically a kind of high abrasion, high strength heavy load doughnut tyre retreading prevulcanized tire tread rubber.
Background technology
Cargo truck tire multirow is sailed in good road surface, and taking highway as main, and cargo truck tire running time is long, load is large.Tread rubber wear resistance is good, the intensity high work-ing life that can improve tire.The carcass of truck tyre renovation use is the old carcass after using, tyre-e/or performance declines to some extent compared with new tyre, add in refurbishment process and also will again heat tire, so the tyre-e/or performance of renovation rear tyre is not as new tyre, require the prevulcanized tire tread rubber of renovation use not only to want wear resistance well to want that heat-dissipating is low, Heat stability is good, avoid because of the high problem that causes renovated tyre carcass to occur inner delamination bulge of tread rubber heat-dissipating simultaneously.
Summary of the invention
The object of the invention is to provide the truck tyre tyre retreading prevulcanized tire tread rubber of a kind of high abrasion, high strength, low-heat-generation, Gao Dingshen.High-wear resistance can improve the actual service life of tire; High strength, height are stretched performance surely, make tire tread rubber distortion in the time that high speed, height year travel little, and heat-dissipating is low, is conducive to improve security and the high speed performance of tire; Low-heat-generation performance can avoid tire in use to cause tire delamination, bulge because tyre temperature is too high, scraps in advance.
The technical scheme that realizes the object of the invention is:
A kind of high abrasion, high strength heavy load doughnut tyre retreading prevulcanized tire tread rubber, adopting 3# smoke sheet rubber is to lead and use part cis-1,4-polybutadiene rubber, also have the high structure high wear-resistant carbon black of novel process N375, precipitated silica VN3, silane coupling agent, thermo-stabilizer HS-80 and multifunctional assistant linking agent WY988, multi-functional processing aid ZNZB746 etc., pass through mixer mixing by proportioning raw materials, produce rubber unvulcanizate, rubber unvulcanizate is extruded, is vulcanized and make ring-type or strip precured tread through tyre surface.Concrete materials and materials consumption weight part proportioning are:
3# smoke sheet rubber 80～90
Cis-1,4-polybutadiene rubber 10～20

Described natural rubber is master, also uses part cis-1,4-polybutadiene rubber, natural rubber good combination property, as: tensile strength is high, heat-dissipating is low, elasticity is large, elongation is high, wear resistance is good.Cis-1,4-polybutadiene rubber abrasion performance, flexural property are good.
The described reinforcement system high structure high wear-resistant carbon black of adopting new technology, the high structure high wear-resistant carbon black of novel process wear resisting property is good, surely stretch height, heat-dissipating is low;
Described white carbon black, silane coupling agent, white carbon black and silane coupling agent reduce heat-dissipating when also using the tear strength that can improve sizing material.
Described thermo-stabilizer HS-80 is improved thermostability and the stress at definite elongation of sizing material.
Described multifunctional assistant linking agent WY988 can reduce sizing material heat-dissipating, improve the wear resisting property of sizing material;
Described multi-functional processing aid ZNZB746 can improve the mixing homogeneity of sizing material, the puncture of resistance to cutting, resist to collapse and use up piece performance, can improve the mobility of sizing material simultaneously.
Described p phenylenediamine type antioxidant 4020 can improve the anti-dynamic aging performance of sizing material, anti-ozone ageing performance.
Described ketone amines antioxidants S-RD can improve the heat-resistant air aging property of sizing material, can reduce the heat-dissipating of sizing material simultaneously;
The surface that described protection wax can move to sizing material forms protective filmy layer, prevents erosion to sizing material of ozone and oxygen and aging.
The vulcanization rate of described sulfenamide type accelerators stress at definite elongation very fast and sizing material is high, can improve the stress at definite elongation of sizing material, is out of shape littlely when sizing material is stressed, and the high speed performance of tire is good.
Advantage of the present invention is: the wear resisting property that has improved cargo truck renovated tyre, improve the work-ing life of tire, reduce tire and in use occurred the problems such as delamination, bulge, explosion because tyre temperature is too high, improved the safety in utilization of cargo truck renovated tyre.
The present invention, by selection, the reasonable disposition of formula to formula raw material types, reaches optimizing and combining of integral formulation performance, has improved work-ing life, safety in utilization and the high speed performance of renovated tyre, and specific performance is in table 1:
