Abstract

The invention discloses a nitrile rubber compound and a preparation method thereof. The nitrile rubber compound is prepared from the following components in parts by weight: 80-150 parts of nitrile rubber, 0.5-8 parts of reinforcing filler, 10-30 parts of foaming agent, 0.5-5 parts of anti-aging agent, 1-15 parts of plasticizer, and 15-50 parts of negative ion stock solution, wherein the negativeion stock solution is prepared by mixing a water-soluble negative ion crystal and water in a weight ratio of (2-10):100. The nitrile rubber compound of the invention contains the added negative ion stock solution, the nitrile rubber compound containing a negative ion component is impregnated to prepare a negative-ion antibacterial glove, so that the glove is endowed with antibacterial ability; andalso with utilization of the characteristic that the a large amount of heat energy is released during a thermal motion process of the negative ion component, the impregnation time is shortened and the impregnation speed is improved. The nitrile rubber compound of the invention has the advantages of strong adhesion and good wear resistance, and is conducive to prolonging the service life of the glove and improving the protective effect.

Description

technical field [0001] The invention relates to the technical field of rubber gloves, in particular to a nitrile rubber compound and a preparation method thereof. Background technique [0002] Gloves are widely used in industries such as petrochemical, paint printing, agriculture and animal husbandry, and automobile machinery maintenance. They are the most important labor protection tools for protecting hands in people's daily work. At present, the commonly used gloves are made of cotton fiber and chemical fiber, which are light, sensitive, and soft; this type of glove has no advantages such as oil resistance, acid and alkali resistance, and corrosion resistance. Therefore, it is often necessary to apply a layer of glue on the fingers or palms of cotton fiber and chemical fiber gloves, which not only increases oil resistance, acid and alkali resistance, and corrosion resistance, but also increases anti-skid performance and heat insulation performance. An indispensable produ...
