Abstract

The invention relates to an application of an alkadiene polymer in preparing rubber masterbatch, masterbatch based on the application and a preparation method thereof. According to the application of the alkadiene polymer in rubber masterbatch, the alkadiene polymer is a powdery or granular homopolymer and / or copolymer, wherein the melting point is 40-80 DEG C, preferably 50-70 DEG C, and the alkadiene polymer accounts for 10-50wt% of the masterbatch. Transpolyisoprene or polybutadiene used in the invention is of good compatibility with almost diene rubber, so that no negative influence on performance of rubber products is caused. The melting point of TPI (Transpolyisoprene) is about 70 DEG C, so that the masterbatch is not adhered under a storage condition without a separant. At the mixing temperature of common rubber, the masterbatch is crystallized and melted and easy to disperse.

Description

technical field [0001] The invention belongs to the field of polymer compounds using inorganic substances or non-high molecular organic substances as ingredients, and specifically relates to the application of diene polymers in the preparation of rubber masterbatches, masterbatches based on the application and a preparation method. Background technique [0002] The use of rubber chemicals has greatly promoted the development of the rubber industry and is an indispensable main component of rubber products. Usually, the additives used in the rubber industry are mainly lumpy or powdery solids, and there are many problems in the production of rubber products. First of all, solid rubber chemicals are prone to dust during production and use, which will not only cause production environmental pollution, affect the physical and mental health of workers, but also cause the loss of active ingredients, affect the performance and quality of rubber products, and may even cause Product q...
