Abstract
The invention relates to a special matt agent for rubber applied in rubber products and a preparation method thereof. The matt agent comprises the following raw materials by weight: 6-12 portions of rubber softening oil, 14-20 of portions stearic acid, 2-8 portions of zinc stearate, 7-13 portions of ceresin, 21-27 of portions emulsifier, 2-8 portions of inorganic carrier, and 27-33 portions of coupling agent. The preparation method comprises the steps as follows: 1) controlling the temperature of a reaction kettle at 180-200 DEG C; 2) sequentially adding the rubber softening oil, the stearic acid, the zinc stearate, the ceresin, the emulsifier, the inorganic carrier and the coupling agent into the reaction kettle; 3) discharging materials after reaction for 60-minute and cooling; 4) crushing and sieving; and 5) checking and packing. The special matt agent for rubber makes the appearance of the rubber products reach ideal matt degree without blooming and white spraying, has no influence to the performance of original products, does not need to change of the formulation of original products, and is simple and convenient as being directly added to the original formulation. The invention is suitable for all the rubber products that need the matt degree, and meets the requirements of domestic and foreign markets.
Description
technical field [0001] The invention relates to rubber raw materials and fine chemical product materials, in particular to a special matting agent for rubber used in rubber products and a preparation method thereof. Background technique [0002] At present, the rubber products industry, such as tires, seals, rubber hoses, tapes, rubber shoes, etc., are ubiquitous: due to the particularity of rubber product production, generally have to go through high-temperature rubber mixing, high-temperature calendering, high-temperature vulcanization and other processes, rubber in these high-temperature Under the influence of thermal oxidation, thermal oxidation is easy to occur, which will crack the rubber molecular chain, cause aging, make the surface of rubber products shiny and powdery, and reduce the service life of the product. Seriously affect the appearance quality, especially not up to the export requirements of European and American countries. Contents of the invention [00...
