Abstract
The invention belongs to the technical field of tires, and particularly relates to tire side rubber for a tire and a preparation method of the rubber. The tire side rubber is prepared from the following raw materials: natural rubber, butadiene rubber, carbon black, an air retardant, zinc oxide, an anti-ageing agent RD, an anti-ageing agent 4020, a stearic acid, aromatic oil, tackifying resin, an internal releasing agent, B-type microcrystalline wax, sulphur and an accelerant NS by a section of blending and vulcanizing process. The air retardant NM360 is added to the formula under the premise of keeping the physical property of the rubber, so that the rubber content can be effectively reduced. Thus, the production cost of the rubber is reduced. Meanwhile, the internal releasing agent TM-80 is added to the formula, so that the mobility of the tire side rubber can be effectively increased, the quality problems such as hungry joints and gaps at the tire side of a product tire are reduced, and the qualified rate of the product tire is increased.
Description
Technical field
The invention belongs to tyre technology, be specifically related to sidewall sizing material and preparation method thereof for a kind of tire.
Background technology
The Main Function protection carcass on sidewall, radial sidewall softness, is used extension strain large, stand to deflect fatigue ratio more serious, but shear strain is little.Its sizing material will have excellent flexible resistance and heat-resisting oxygen, ozone ageing performance, and tensile strength is higher, and elongation is large, and the tackiness of sizing material will be got well.To fulfill this requirement, its formula system uses natural gum and cis-butadiene cement paralled system more, and the consumption of carbon black can not be too many, and sidewall is in the time of sulfuration, can cause due to the illiquidity of sizing material the appearance qualities such as sidewall starved, breach.
Summary of the invention
The object of this invention is to provide a kind of tire sidewall sizing material, physicals is good, cost is low; The present invention provides the preparation method of tire with sidewall sizing material simultaneously, scientific and reasonable, simple, has improved qualification rate.
Tire of the present invention sidewall sizing material, made by the raw material of following parts by weight:
Tire of the present invention sidewall sizing material, preferably made by the raw material of following parts by weight:
Tire of the present invention sidewall sizing material, more preferably made by the raw material of following parts by weight:
Described air hold back agent is air hold back agent NM360, and Kingsoft, Zhengzhou Chemical Co., Ltd. produces.
Described inner pattern releasing agent applicable is inner pattern releasing agent applicable TM-80, and Qingdao pul Chemical Industry Science Co., Ltd produces.
The preparation method of sidewall sizing material for tire of the present invention, step is as follows:
(1) one section mixing: in Banbury mixer, add natural rubber and cis-1,4-polybutadiene rubber, Banbury mixer rotating speed 40-60 rev/min, pressurization 15-18MPa, 20-40s rises floating weight, now, each component high polymer material has all been viscous state, then, drop into carbon black, air hold back agent, zinc oxide, anti-aging agent RD, antioxidant 4020, stearic acid, tackifying resin, inner pattern releasing agent applicable, Type B microcrystalline wax, pressurization 15-18MPa rises floating weight in the time that temperature reaches 120-130 DEG C, drop into aromatic hydrocarbon oil, pressurization 15-18MPa, binder removal during to 150-170 DEG C, obtains one section of rubber unvulcanizate;
(2) add sulphur technique: in Banbury mixer, drop into one section of rubber unvulcanizate, add sulphur, accelerator NS, rotating speed 20-40 rev/min, pressurization 15-17MPa, 20-40 rises floating weight second, pressurization 15-17MPa, 30-50 rises floating weight second, and binder removal, to obtain final product.
The present invention compared with prior art, has following beneficial effect:
The present invention, under the prerequisite of physicals that keeps sizing material, adds air hold back agent NM360 can effectively reduce gum content in formula, thereby reduces the production cost of sizing material.Meanwhile, in formula, add inner pattern releasing agent applicable TM-80 can effectively increase the mobility of sidewall sizing material, reduce the quality problems such as finished product tire sidewall starved, breach, improve the qualification rate of finished tire.Air hold back agent NM360 is after extracting from the low volatilization pitch of high quality cleaned coal, and through multi-level deep processing, formation has lamellar structure and better strengthening action moulding dose, and NM360 has hydrophobicity and reinforcing property.
