A kind of preparation method of nitrile microcellular foaming non-slip gloves

Abstract

The invention relates to a preparation method of nitrile microporous foamed non-slip gloves. The gloves are dipped in nitrile pre-vulcanized glue once, and then dipped in nitrile pre-vulcanized microporous foamed glue twice. The double-pass nitrile pre-vulcanized microcellular foaming mortar is foaming mortar obtained by foaming with a physical or chemical foaming agent, and the foaming mortar is also mixed with unfoamed expandable microsphere foaming agent . After the second dipping, these expandable microsphere blowing agents are transferred to the surface of the glove, and in the subsequent vulcanization and drying process, the expandable microsphere blowing agent mixed with unfoamed expandable microspheres is re-expanded due to high temperature. Foaming and forming a number of foaming protrusions, so that the nitrile rubber gloves have a large specific surface area and an anti-slip effect close to / exceeding the nitrile scrub gloves, and the gloves are soft and comfortable to wear, and have anti-slip and anti-chemical characteristics. Compared with the frosted gloves, the present invention has the advantages of simpler preparation process, more environmental protection, water saving and the like.

Description

technical field [0001] The invention relates to the technical field of coated gloves, in particular to a preparation method of nitrile microcellular foamed 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 relatively high polarity. The nitrile rubber formed after curing has excellent water resistance, chemical corrosion resistance and oil resistance, and is more and more widely used in the preparation of gloves and the like. However, the texture of nitrile rubber is relatively hard, the surface is relatively flat and smooth, and it becomes smoother when it meets water or oil. When used as protective gloves, its anti-skid effect is poor, and the grip is not good when worn, which leads to the application function ...

AI Technical Summary

Problems solved by technology

Although the advantages of nitrile scrub gloves and nitrile wrinkled gloves are outstanding, there are also many problems that cannot be ignored, including: (1) the preparation process of scrub gloves is to spray a large amount of inorganic salt ( Sodium chloride or sodium sulfate), and then washed with water for many times in Linxi or soaking, not only the air in the workshop is easily polluted by dust, it needs to consume a lot of water resources, and the spilled sodium chloride and sodium sulfate will corrode metal pipes and metal equipment. Equipment breakage is accelerated, which indirectly increases the production cost of the enterprise

(2) Butyronitrile wrinkle gloves need to be impregnated with organic acid and other wrinkle treatment agents, the production environment is polluted, and the sour smell on the surface of the gloves is relatively heavy
