Abstract
The invention relates to a method for preparing rubber, and provides a method for preparing low-heat-generation fatigue-resistant vulcanized rubber. In a rubber formulation, starch or modified starch is adopted to be combined with a coupling agent into a low-heat-generation fatigue-resistant additive; other additives such as carbon black, stearic acid, zinc oxide, accelerator, sulfur, anti-aging agent and process oil are not changed; and a main rubber material selected is polydiolefin rubber, such as natural rubber, styrene-butadiene rubber, 3-polybutadiene rubber, butadiene acrylonitrile rubber or a mixture thereof. Through common rubber processing technology and equipment, the starch or the modified starch is taken as a functional rubber additive to prepare the rubber with low heat generation and long fatigue lifespan, and the heat generation and bending-resistant lifespan of the vulcanized rubber are obviously improved. The rubber of the species can be used in tires and other rubberproducts.
Description
Technical field
The present invention relates to a kind of preparation method of rubber, particularly relate to the preparation method of a kind of low-heat-generation, fatigue-resistant vulcanized rubber.
Background technology
In rubber industry, the main strengthening agent of traditional rubber is based on carbon black type filler.But because carbon black can do great damage to surrounding environment in process of production, simultaneously, carbon black exists the problems such as heat is higher, elasticity is low of giving birth to as the vulcanized rubber that rubber reinforcing filler obtained, this is unfavorable for the work-ing life of improving rubber item, often scrap in advance as the doughnut at a high speed owing to explosion takes place Sheng Re, therefore, people are seeking a kind of functional agent instead of part carbon black always, and the vulcanized rubber of preparing low-heat-generation, high fatigue life is used for tire tread, sidewall and other rubber components.At present, adopt filler to reduce the viviparous heat of wheel and do not see report both at home and abroad as yet.External starch/softening agent the mixture that adopts is used for the tire flexibility body, to reduce tire drag.As U.S. Pat 5,672,637, adopt common complete processing, with composites of starch and rubber mix, can obtain rolling resistance tyre.The density of starch is at 1.3-1.5g/cm
3Between, lower than general rubber with filler.Simultaneously, a large amount of hydroxyl on starch surface can be implemented modification, it is possessed and rubber between produce the possibility of stronger indirect interfacial adhesion.Elasticity is increased simultaneously, this is because the kindliness of starch molecular chain is bigger, when rubber is subjected to external force, the chain movement of rubber molecular chain and ether esterification starch molecular chain can adapt to suffered external force more rapidly and the conformation that changes molecular chain is unfolded molecular chain comes, when external force was removed, its molecular chain can well return to original state again.Therefore, be that stronger theoretical basis is arranged with starch as the novel strengthening agent of rubber.Starch is developed into the function of tonic chord auxiliary agent of rubber, will effectively improve vulcanized rubber elasticity, reduce rubber and give birth to heat, increase substantially the fatigue lifetime of rubber.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of low-heat-generation, fatigue-resistant vulcanized rubber, it is functional agent that this method adopts starch or treated starch, by ordinary process equipment, prepares low-heat-generation, antifatigue rubber.
