Abstract
The invention firstly discloses a rubber processing aid. The rubber processing aid is prepared by mixing and granulating the following raw materials in parts by weight: 700-800 parts of stearic acid, 0-100 parts of zinc oxide, 10-150 parts of anhydrous aluminum trichloride and 0-200 parts of zinc oleate. The invention secondly discloses a preparation method of the rubber processing aid. The preparation method comprises the steps of 1) firstly adding the stearic acid to a reaction kettle, heating to 125 to 155 DEG C, next, adding the anhydrous aluminum trichloride, reacting for 2-3 hours under a constant temperature condition, and then adding zinc oxide and reacting for 1.5-5 hours under the constant temperature condition; 2) adding zinc oleate to the reaction kettle, mixing evenly and reacting for 35-45 minutes under the constant temperature condition; and 3) quantificationally feeding the mixture in the reaction kettle to a granulation extruder for granulation, thereby obtaining the aid. The rubber aid is capable of improving the fluidity of the rubber material, increasing the extrusion speed of the rubber material, accelerating quick dispersion of fillers added to the rubber material such as an anti-aging agent, a vulcanizing agent, an accelerant, carbon black and calcium carbonate, and thus improving the uniformity and the stability of the rubber material.
Description
technical field [0001] The invention relates to the field of polymer materials, in particular to a rubber additive and a preparation method thereof. Background technique [0002] Nowadays, the processing technology of rubber tires is relatively mature. In order to improve the strength, plasticity, elasticity, durability, and anti-aging performance of rubber tires, the existing technology generally adds various Different rubber additives have different main functions. Some rubber additives are mainly used to improve the fluidity of the rubber, that is, to reduce the viscosity of the rubber to facilitate rubber extrusion and product molding. The additives are mainly used to increase the tensile strength of the rubber, so that the cohesion of the rubber is improved, thereby improving the strength and durability of the rubber. Some additives are mainly used to promote the uniform mixing of the rubber and the filler in the rubber. In order to increase the stability of the rubber...
