Problems solved by technology

And the two will also react during packaging, transportation, storage and actual use, that is, rubber products produced by traditional methods are not conducive to storage
And in the processing of rubber products in the traditional process, it is necessary to select the corresponding colloid as the carrier, such as EPDM rubber can only use EPDM rubber as the masterbatch of the carrier, which makes the carrier not universal and applicability

Abstract

The invention discloses a novel pre-dispersion master batch and a preparing method thereof.The novel pre-dispersion master batch comprises carriers and rubber chemicals.The carriers include macromolecular polymerization wax, coumarone and lubricant EBS.The preparing method for the formula comprises the following steps that the raw materials in the carriers are mixed evenly according to a ratio; the rubber chemicals are added into the carriers and mixed evenly to obtain a mixture; the mixture is extruded out and granulated after being cooled, and the novel pre-dispersion master batch is obtained.The novel pre-dispersion master batch can be directly extruded out to be cut into granules without rubber mixing, energy consumption is low, and the yield is high; the obtained product has considerable hardness, does not absorb moisture and is beneficial to storage after being conveyed through a refrigeration house and subjected to cold-cutting.In addition, the novel pre-dispersion master batch has extensive universality and applicability, and the carriers can be suitable for the machining process of any rubber products and can not react with the rubber products.

Description

technical field [0001] The invention relates to a rubber additive, in particular to a novel pre-dispersed masterbatch and a preparation method thereof. Background technique [0002] Rubber is an elastic polymer. Rubber can be obtained from the sap of some plants, or it can be man-made. Rubber products are widely used in industry and life. [0003] During the processing of rubber products, various systems other than rubber need to be added: such as reinforcing agent, vulcanizing agent, accelerator, anti-aging agent, active agent, dispersant, cord, etc. Most of the auxiliary materials are powders, and a considerable part is chemically synthesized, which is harmful to the human body. Moreover, the powder is not conducive to automatic feeding, requiring manual weighing, which is not environmentally friendly and has low efficiency. In the traditional process, the powder and rubber are directly kneaded into agglomerates according to the proportion, and then forced to extrude and...
