Acrylonitrile-butadiene rubber latex auxiliaries for preparing white nitrile gloves and preparation method of acrylonitrile-butadiene rubber latex auxiliaries

Abstract

The invention discloses acrylonitrile-butadiene rubber latex auxiliaries for preparing white nitrile gloves and a preparation method of the acrylonitrile-butadiene rubber latex auxiliaries. The acrylonitrile-butadiene rubber latex auxiliaries are prepared from, by weight, 15-30 parts of zinc oxide powder, 20-30 parts of sulfur powder, 2-9 parts of accelerant BZ powder, 5-12 parts of accelerant EZ powder, 2-9 parts of anti-aging agent powder, 35-50 parts of titanium oxide powder, 1-6 parts of dispersing agent powder and a proper amount of water. All raw materials are stirred and dispersed after being mixed and then ground in a recycled mode till the particle size of powder in the mixing liquid is less than or equal to 5 micrometers, and mixed acrylonitrile-butadiene rubber latex is obtained. The acrylonitrile-butadiene rubber latex prepared through the method is accurate in raw material matching, more convenient to use and low in production cost, and the prepared nitrile gloves are high in smoothness degree, high in pinhole qualified rate and stable in quality.

Description

technical field [0001] The invention relates to the technical field of nitrile gloves, in particular to a formula of nitrile latex auxiliary materials used for preparing white nitrile gloves. Background technique [0002] With the rapid development of economic construction, people's awareness of self-protection has gradually increased, and the use of disposable gloves has increased rapidly, prompting the emergence of disposable gloves products that are more convenient to use and more functional. Among them, nitrile gloves are the most popular among users. This is because nitrile gloves have excellent physical properties, with a tensile strength of more than 20Mpa, an elongation at break of more than 500%, superior elasticity, and comfortable wearing; Chemical performance, can provide good chemical protection against acid, alkali, petroleum, various organic solvents, etc.; and does not contain protein, amino compounds and other harmful substances, and rarely causes skin aller...

AI Technical Summary

Problems solved by technology

1. For the production of different nitrile gloves, the addition ratio of nitrile excipients is different. At the same time, due to the different solid content of each batch of imported nitrile excipients, the addition amount of various emulsions is different in each batching, which is very It is easy to cause the wrong addition ratio of nitrile excipients, resulting in quality problems of nitrile gloves

2. There are many types of nitrile auxiliary materials, and the operation is troublesome and the workload is large when adding

3. The nitrile auxiliary materials are all imported, and the purchase cycle is long. When the various emulsions arrive at the factory, they have already settled seriously, especially the sulfur emulsion, which needs to be stirred before use, and then the ingredients are mixed. Inaccuracy affects product quality

4. The cost of imported accessories is high

The quality problems of nitrile gloves may directly lead to the loss of corresponding customers
