Problems solved by technology

At present, there are few institutions in China that specialize in the research and application of nitrile synthesis technology and application in the field of special labor protection gloves. The mainstream nitrile latex synthesis method adopts the low temperature method, which takes a long time, low efficiency, high consumption, and low raw rubber strength. It also needs to be vulcanized for a long time to be useful, but the vulcanization time has a great impact on the performance of the emulsion and is not easy to control

Abstract

The invention discloses wear-resistant water-based resin for special labor protection gloves and a preparation method of the wear-resistant water-based resin. The preparation method comprises the following steps: firstly, adding a part of soft water, a pH value regulator, a dispersing agent, a mixed monomer, a compound emulsifier and an initiator into a polymerization kettle, vacuumizing, and heating for reaction; then slowly adding a part of residual formula raw materials at a constant speed, carrying out heat preservation reaction, then heating, slowly adding the residual formula raw materials at a constant speed, carrying out heat preservation stirring until the monomer conversion rate reaches 90% or above, adding a defoaming agent and a stabilizing agent, eliminating residual monomers, cooling, adjusting the pH value, and filtering. The water-based resin obtained by the invention can be used for special labor protection gloves, and has good wear resistance and relatively high tensile strength and elongation.

Description

technical field [0001] The invention relates to a water-based resin, in particular to a wear-resistant water-based resin for special labor protection gloves and a preparation method thereof. It belongs to the technical field of glove processing. Background technique [0002] With more and more attention paid to safety in production, it has become particularly important to wear high-quality labor protection products to prevent accidents. The hand is a part of the human body with a high injury rate, so it is particularly important to choose and correctly use safety gloves to prevent hand injuries. From food preparation to medical to industrial production, rubber labor protection gloves have a wide range of uses. [0003] There are many rubbers used for special labor protection gloves, but from an economic point of view, most of them use styrene-butadiene latex with simple, easy-to-obtain and low-cost raw materials. The traditional protective gloves made of styrene-butadiene...
