Description
Technical field
The present invention relates to a kind of carbon black disperser composition and method of making the same and application, and a kind of rubber processing method.
Background technology
In order to improve physical strength and the wear resistance of rubber, need in rubber, add a certain amount of carbon black.Due to the singularity of carbon blacksurface performance, be difficult to be uniformly dispersed in rubber, thus the dispersion effect affected in rubber and multiple mechanical property.In order to solve this difficult problem, people have worked out some carbon black dispersers containing fatty acid soaps or tensio-active agent.Because fatty acid soaps or tensio-active agent and other auxiliary agent such as vulcanizing agent, vulcanization accelerator, scorch retarder etc. have reactive behavior, as improper in collaboration, incipient scorch will be caused, extend curing time etc., products machinery degradation can be caused.Therefore this kind of dispersion agent also exists and uses the shortcomings such as inconvenient, physical strength is low.
CN1289793A discloses a kind of carbon black disperser for rubber and production method thereof, described carbon black disperser for rubber is made up of following raw material, and its weight percent is: oxidized polyethlene wax 30-80%, petroleum resin 20-70% and staybelite 0-10% compound are formulated.This production method is: first mixed by the staybelite of the oxidized polyethlene wax of 30-80%, the petroleum resin of 20-70% and 0-10%, then melting at the temperature of 80-120 DEG C, finally cools film-making i.e. obtained carbon black disperser.The dispersiveness of carbon black can be made to have improvement to a certain degree although add this carbon black disperser, but, the defects such as the autohension that simultaneously also can produce rubber unvulcanizate is poor, vulcanization rate is slow and lubricant effect is poor, as improper in collaboration, tire product mechanical property also can be made to decline, and wear resistance is deteriorated.And, because vulcanization rate causes production efficiency low slowly, thus increase production cost.Therefore, there is defects such as using inconvenience, production cost is high, tire machinery intensity is low and wear no resistance in this kind of carbon black disperser.
CN103304881A discloses a kind of new type rubber carbon black disperser and preparation method thereof, and described carbon black disperser for rubber is made up of following raw material: polyethylene wax or oxidized polyethlene wax 10-30 part, Zinic stearas 10-20 part, stearic acid 10-30 part, polyoxyethylene glycol 10-30 part and pentaerythritol stearate 30-80 part complex configuration form.This patent also discloses the preparation method of this new type rubber carbon black disperser, it is characterized in that, polyethylene wax or oxidized polyethlene wax, stearic acid, polyoxyethylene glycol, pentaerythritol stearate are stirred melting mixing in 80-130 DEG C in proportion, then at the temperature of 110-150 DEG C, add Zinic stearas stir melting, and described Zinic stearas added once every ten minutes, add for three times, each addition accounts for 1/3rd of Zinic stearas total amount, and cooling film-making or fusing and pelleting obtain new type rubber carbon black disperser.Although add this carbon black disperser can improve the processing safety of rubber size, physical and mechanical properties and vulcanization rate, improve the dispersiveness of carbon black filler, this invention cost is higher.
Therefore, how to prepare a kind of carbon black disperser composition, when being applied to rubber, while ensureing that rubber has good vulcanization characteristics, significantly can improve carbon black obtains dispersed, and then improve the physical and mechanical properties of rubber item, and a kind of rubber processing method containing this carbon black disperser composition needs to study further.
