Preparation method of slip-proof nitrile gloves

Abstract

The invention relates to a preparation method of slip-proof nitrile gloves. The preparation method comprises the steps of S1, preparing first-pass rubber pulp and second-pass rubber pulp; mixing a mixture comprising, by mass, 1000 parts of nitrile latex and 8-20 parts of thickening agent to obtain the first-pass rubber pulp; mixing a mixture comprising, by mass, 1000 parts of nitrile latex, 1-20 parts of stabilizing agent, 5-20 parts of foaming agent and 2-6 parts of thickening agent to obtain the second-pass rubber pulp; S2, conducting first-pass impregnation, impregnating glove bodies (chemical fiber glove bodies need to be impregnated in a coagulating agent) in the first-pass rubber pulp, taking out the glove bodies for low-temperature pre-drying to obtain glove intermediate products; S3, conducting second-pass impregnation, impregnating the glove intermediate products in the second-pass rubber pulp; and S4, conducting vulcanized drying and high-temperature foaming, taking out the glove intermediate products after impregnation in the second-pass rubber pulp, conducting vulcanized drying at the first temperature and then conducting foaming at the second temperature, wherein the second temperature is higher than the first technology. A layer of the foamed rubber pulp coated on the surface of each glove is foamed after high-temperature baking without irregular bumps and pits, and the slip-proof per of the gloves can be improved.

Description

technical field [0001] The invention relates to a preparation process of protective gloves, in particular to a preparation method of nitrile non-slip gloves. Background technique [0002] The preparation method of rubber gloves is generally to form a layer of rubber layer after the textile glove embryo is impregnated with natural latex, synthetic latex, etc. on the surface, so that the gloves are waterproof. [0003] Nitrile latex is a kind of latex with larger polarity. The nitrile rubber formed after curing has excellent water resistance, oil resistance and chemical corrosion resistance, so it is more and more widely used in the preparation of gloves and the like. However, the surface of nitrile rubber is relatively flat and smooth, and it becomes smoother when it meets water or oil. When it is used as a protective glove, its anti-skid effect is poor, which limits the application function of nitrile gloves. For this reason, the industry usually creates textures on the sur...

Problems solved by technology

However, the method of salt spraying not only destroys the latex, but also requires a large amount of water to clean the sodium sulfate or sodium chloride used, which causes waste of water resources and pollutes the environment.

At the same time, the process of salt spraying will pollute the air in the workshop with dust, which will have adverse effects on the health of the workshop staff. The falling sodium chloride and sodium sulfate will corrode metal pipes and metal equipment, and damage the service life of equipment

More importantly, because the sprayed salt or the particles used cannot be cross-linked with the latex, these particles (salt, etc.) will fall off (ie, slag) with the wear of the glove surface during use, polluting the application products the environment is making

Especially in the production process of food, medicine, liquid crystal display and precision electronic components with high cleanliness requirements, the nitrile non-slip gloves produced by spraying salt / particles cannot be used at all

Therefore, the nitrile non-slip gloves prepared by existing process method are subject to many restrictions in application

[0005] In view of the many problems existing in the prior art, the inventor hopes to design a new glove preparation method that can produce anti-skid lines on the surface of nitrile gloves, which can increase the roughness of the surface of nitrile gloves and avoid slag during use question
