Problems solved by technology

According to its use, it can be divided into medical gloves, industrial gloves and household gloves. At present, gloves only play a simple role in isolation and protection of human hands. The advantages of nitrile gloves are excellent oil resistance and good wear resistance. Good heat resistance, its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, slightly lower elasticity, and relatively hard hand feeling

Abstract

The invention relates to a preparing method of double-layer rubber gloves. The double-layer rubber gloves are subjected to two-time impregnation and are impregnated in emulsion latex for the first time and butyronitrile latex for the second time. The preparing method includes the concrete steps that 1, emulsion latex is prepared; 2, butyronitrile latex is prepared; 3, after being dried, a glove mold impregnated with coagulator is impregnated for 5-20 s in the emulsion latex, dried for 2-3 min at the temperature of 110-130 DEG C and impregnated for 5-20 s in the butyronitrile latex; 4, after leaching and crimping are carried out, the glove mold is put into a dryer at the temperature of 125-150 DEG C and dried for 30-60 min, and the finished double-layer rubber gloves product is obtained through the processes of chlorination and demolding. The double-layer rubber gloves are high in oil resistance, abrasion resistance, heat resistance and low temperature resistance and high in insulating property and elasticity and have a good handfeel.

Description

technical field [0001] The invention relates to a method for preparing rubber gloves, in particular to a double-layer rubber glove with an outer layer of nitrile and an inner layer of latex and a preparation method thereof, belonging to the technical field of rubber products. Background technique [0002] Gloves have been widely used in people's production and life because of their barrier protection and can well protect the safety of users. According to its use, it can be divided into medical gloves, industrial gloves and household gloves. At present, gloves only play a simple role in isolation and protection of human hands. The advantages of nitrile gloves are excellent oil resistance and good wear resistance. It has good heat resistance, but its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, slightly lower elasticity, and relatively hard hand feeling. Contents of the invention [0003] The technical problem to be ...
