Problems solved by technology

At present, the existing rubber deodorants are all prepared by mixing activated carbon or other organic materials. The preparation process is complicated, and strong acid or alkali is needed in the preparation process, which is easy to cause environmental pollution, poor compatibility, and short duration. After use, the selectivity is poor, the adsorption capacity is small, the efficiency is low, and the dispersion and compatibility in rubber products are poor.

Abstract

The invention discloses a deodorant composition. The deodorant composition is characterized by being prepared from, by weight, 72%-92% of opal, 2%-8% of a silane coupling agent, 2%-8% of stearic acid, 1%-12% of titanium dioxide and 1%-4% of zinc oxide. A preparation method of the deodorant composition includes opal treatment, primary mixer preparation and finished product preparation. A prepared product is great in rubber product deodorizing effect and obtained by addition of other components on the basis of opal, and simplicity in preparation process, low cost, less proneness to environment pollution, high compatibility and long efficacy time are realized.

Description

technical field [0001] The patent of the present invention relates to a deodorant, especially a deodorant prepared for rubber and plastic. Background technique [0002] Rubber deodorant is a chemical additive used to eliminate, weaken or cover odor. It can be divided into many types according to different uses. It can effectively reduce or eliminate the odor or odor caused by rubber additives and residual monomers in the rubber itself. It is especially suitable for some rubber products that are reprocessed using secondary recycled materials. Rubber formulation is a rather complicated process. The number of materials added to a formula varies from a dozen to dozens, because most of them are petroleum and chemically purified organic materials, with a variety of raw materials and additives. , under the action of heat and shear force, the small molecular materials in the composite materials in the raw materials or additives will be gradually released, accompanied by an unpleasa...
