Problems solved by technology

[0005] The Chinese patent literature discloses a two-color glove, the patent name of which is "medical double-layer two-color latex gloves", and the publication number is "CN201805977U". The two-color gloves are realized by wearing two-layer gloves of different colors. Gloves are inconvenient to use and cause more waste of gloves
[0006] CN102371687A discloses a method for processing two-color rubber gloves, but it solves the technical problem that the inside and outside are easy to wear wrongly, that is, different colors are used for the inside and outside, and in the material formula of the inside and outside, except for the pigment, the rest of the components all the same

Abstract

The invention discloses a method for manufacturing an NBR glove with different colors in the palm of the hand and the back of the hand. The method includes the first step of preparing NBR latex for the palm side of the glove and NBR latex for the back side of the glove, the second step of impregnating a mould in coagulating agents and drying the mould, the third step of impregnating the back side of the mould into the NBR latex for the back side of the glove for 9-11 seconds, wherein the impregnation depth accounts for half of that of the mould, the fourth step of drying the mould at the temperature ranging from 106 DEG C to 110 DEG C, the fifth step of impregnating the palm side of the mould into the NBR latex for the palm side of the glove for 9-11 seconds, wherein the impregnation depth accounts for three-fifths of that of the mould, then carrying out coiling, drying the mould at the temperature ranging from 113 DEG C to 115 DEG C to form a finished product of the glove, and the sixth step of carrying out chlorination, soaking and washing, cleaning, drying, demoulding on the finished product of the glove. According to the method, the manufactured glove has different colors in the palm side of the glove and the back side of the glove, ingredients for materials of the palm side of the glove and materials of the back side of the glove are different, the palm side of the glove is durable in use, and the back side of the glove is low in cost.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a method for preparing nitrile rubber gloves with different colors on the palm and the back of the hand. Background technique [0002] With the improvement of people's living standards and the enhancement of health protection awareness, nitrile rubber gloves have gradually entered the lives of ordinary people; people use nitrile rubber gloves in work and labor, which can effectively protect hands and prevent them from being exposed to the external environment. Adverse effects, soiling or injury to hands. [0003] The working side of the glove is usually the palm side, while the back side of the hand is usually not in direct contact with the working substance. In actual use, damage to the palm side usually leads to the scrapping of the glove, while the back side of the hand is intact at this time. The gloves in the prior art are usually made as a whole, and the material...
