Description
Technical field
The invention belongs to motorcycle tyre sidewall rubber combination and preparation method thereof, particularly relate to a kind of motorcycle tyre sidewall rubber combination that can extend the mold cleaning cycle and preparation method thereof.
Background technology
Tire is to be fabricated by by multiple material combination, can become finished tire after needing employing high temperature vulcanized in a common tire production process. tire appearance is required height by finished tire, surface requirements is bright and clean without dirt, usual surface of tyre dirt comes off from mould stuck foreign matter and sizing material, therefore vulcanized model for tyre has significantly high cleannes requirement, mold clean is generally adopted to complete cleaning in the course of processing, the time more long impact on production efficiency of mold cleaning tool is more big, also impact sulfuration crudy, in order to keep tire appearance surface without dirt preferably in tyre production, reduce the time of mold cleaning tool again simultaneously, except improving cleaning efficiency, can also pass through to improve sizing compound formula minimizing to come off and dirt.
Summary of the invention
The present invention discloses a kind of motorcycle tyre sidewall rubber combination extending the mold cleaning cycle and preparation method thereof according to prior art deficiency. The problem to be solved in the present invention is to provide one can meet tyre performance requirement, meets again national standard, and more economical safety can extend the motorcycle tyre sidewall rubber combination in mold cleaning cycle, the preparation method that present invention also offers above-mentioned tyre stock.
The present invention is achieved through the following technical solutions:
Extend the Motorcycle tire side glue combination in mold cleaning cycle, it is characterized in that described size composition includes following components: natural rubber, butadiene-styrene rubber, butadiene rubber, environmental friendly regenerated glue, white carbon black, zinc oxide, stearic acid, age resistor, sulfur, high hydrocarbon oil, accelerator, reinforcing agent, viscosifier and dispersant.
Described white carbon black is the mixture of in white carbon black N220, white carbon black N234, White Carbon black or several.
Described age resistor is the mixture of or any two or whole three in antioxidant 4020, anti-aging agent RD, antioxidant BLE-W.
Described accelerator is the mixture of or two in accelerant CZ, accelerator NS.
Described dispersant is A78.
Size composition described further is made up of the component of following parts by weight: natural rubber: 30��40 parts; butadiene-styrene rubber 1712:25��35 part; butadiene rubber BR9000:45��25 part; white carbon black N220:35��45 part; white carbon black N234:15-25 part; environmental friendly regenerated glue: 200 parts; zinc oxide: 3.5��5 parts, stearic acid: 0.5��1.5 part, antioxidant 4020: 0.5��1.5 part; accelerator: 0.1��0.6 part; reinforcing agent: 10��20 parts, dispersant: 0.5��1.5 part, high hydrocarbon oil: 5��15 parts; C5 resin: 1��3 part, insoluble sulfur: 1��4 part.
Preferred size composition is made up of the component of following parts by weight: natural rubber 1# marks glue: 30 parts, butadiene-styrene rubber 1712:25 part, butadiene rubber BR9000:45 part, white carbon black N220:45 part, white carbon black N234:25 part, zinc oxide: 5 parts, stearic acid: 1.5 parts, age resistor: 1.5 parts, accelerator: 0.6 part, environmental friendly regenerated glue: 200 parts, dispersant: 1 part, high hydrocarbon oil: 8 parts, C5 resin: 2 parts, insoluble sulfur: 3 parts.
The preparation method of a kind of Motorcycle tire side glue extending the mold cleaning cycle, comprises the following steps:
1) preparing each raw material by above-mentioned each component number, by natural rubber, butadiene-styrene rubber, cis-butadiene cement, environmental friendly regenerated glue is plasticated 60 seconds in banbury, makes plastic film, parks more than 8 hours;
2) by step 1) after the plastic film that obtains plasticates 60 seconds in banbury, add white carbon black total amount 3/4ths and, viscosifier, zinc oxide, stearic acid, age resistor, resin, binding agent, in banbury mixing 120 seconds, add remaining 1/4th white carbon blacks and aromatic naphtha, in banbury mixing 400 seconds, make elastomeric compound;
3) by step 2) elastomeric compound made parks after more than 4 hours, adds accelerator on a mill until, insoluble sulfur is mixing namely can be made into required tyre stock.
In combinations thereof, high hydrocarbon oil is the environmental protection raw material substituting normal aromatic hydrocarbon oil, tradition aromatic naphtha is low because of arene content, owing to aromatic naphtha is low, carbon black in tire and sizing material etc. can not effectively form " sea " item, and when causing the low rear operation sulfuration of sizing material dispersibility, mold cleaning declines cycle time.
In combinations thereof, environmental protection reclaimed rubber has the advantage that sizing material no blooming within storage period. Keep sizing material component and performance homogeneous; Overcome the shortcoming because bloom causes sizing material poor adhesion; Preventing the pollution to goods and mould and eliminate the painting sizing process increased for overcoming bloom, Congress of Industrial Organizations's automation of making a living provides condition. Non-migratory phenomenon in adjacent glue-line. Particularly in the sizing material of cis-butadiene cement and butyl rubber, common reclaimed rubber migration velocity is significantly high, can avoid with addition of after environmental friendly regenerated glue. Burn with depositing process reduces mixing. Shorten cure time. After reaching curing temperature, it has " activation stage ", i.e. a chain type depolymerisation, makes curingprocess rate accelerate, and reduces sulfur consumption, is conducive to the improvement of goods ageing properties. Be conducive to the bonding of rubber and other materials. In tire production, can effectively avoid bloom, be not easy to produce prevulcanization, and make sizing material keep good stickiness, be conducive to forming operation, and guarantee the uniformity that vulcanizate vulcanizes, it is ensured that constant product quality.Environmental friendly regenerated glue is simultaneously also without metallic contamination matter and the easy lower-molecular substance sprayed, and in combinations thereof, C5 resin is hydrocarbon resin, equally the moistness of sizing material and the dispersibility of carbon black is very helpful.
The raw-material tire tread compound of above-mentioned addition, its breaking strength, hot strength and hardness are all maintained. Above-mentioned each raw material is commercially available, and its title is likely to there is difference, but composition is identical.
In sum, the sizing material that tire fabric combination adopting the present invention and preparation method thereof obtains has better breaking strength, hot strength and hardness; Meeting Standard, the present invention, by adopting described environmental friendly regenerated collagen material, is equipped with the design of rational composition, greatly reduces in the hidden danger produced and in use procedure, processor and user are caused, and the safety of product, economy and adaptability are wider. Tire tread abrasion resistant compound of the present invention combination complies fully with country and industry related request, in tire vulcanization process, the mold cleaning tool time is greatly prolonged simultaneously, finished tire outward appearance, without dirt, meets the production efficiency of tire production business, also improves competitiveness and the value of tire simultaneously. Adopt the combination containing larger amount of environmental friendly regenerated glue to do sidewall rubber, it is possible to minimizing lower-molecular substance uses while ensureing performance, make sulfurizing mould in tyre vulcanization processing pollute and reduce the prolongation mold cleaning cycle.
