Problems solved by technology

The disadvantage is that butyl rubber is less resistant to petroleum solvents, coal tar and aromatics, etc.
[0003] Because butyl rubber has the above defects, it needs to be compensated by compounding hydrogenated nitrile rubber. Hydrogenated nitrile rubber has better resistance to chemical corrosion and aromatic hydrocarbons, but has poor air tightness, hard and brittle film, and easy to crack
[0004] Using butyl rubber or hydrogenated nitrile rubber alone, the broad spectrum of protective chemicals is not wide, and it needs to be compounded to make up for each other

Abstract

The invention discloses a composite type chemical corrosion-resistant airtight protective glove and a preparation process thereof. The production raw materials of the glove include primary glue, secondary glue and tertiary glue, and the main materials of the primary glue and the secondary glue are respectively hydrogenated butyl Nitrile rubber and butyl rubber, the tertiary rubber raw material is butyl rubber. The raw materials for the production of primary rubber include hydrogenated nitrile rubber, neoprene, sulfur, zinc oxide, anti-aging agent, accelerator ZDC, accelerator PX, flat plus "O" and carbon black. The raw materials for the production of secondary rubber include 40%-50% butyl latex, 30%-35% hydrogenated nitrile latex and 10% potassium laurate solution. The present invention adopts the method of compounding two kinds of rubbers with completely different polarities and complementary properties, which solves the shortcomings of hydrogenated nitrile rubber, which is hard, brittle and easy to crack; meanwhile, the present invention adopts the processing method of three-time dipping method, which can improve the gloves Excellent tear resistance, so as to improve the performance and service life of the glove. The same rubber is used for the third glue and the second glue, so that the nylon lining can be tightly attached to the film.

Description

technical field [0001] The invention relates to the field of preparation of protective gloves, in particular to a composite chemical corrosion-resistant airtight protective glove and a preparation process thereof. Background technique [0002] Existing butyl nylon lined gloves are impregnated with a single type of rubber—butyl as the main material. Butyl rubber is the most air-tight rubber and has certain chemical corrosion resistance. The disadvantage is that butyl rubber is less resistant to petroleum solvents, coal tar and aromatics. [0003] Because butyl rubber has the above defects, it needs to be compensated by compounding hydrogenated nitrile rubber. Hydrogenated nitrile rubber has better resistance to chemical corrosion and aromatic hydrocarbons, but has poor air tightness, hard and brittle film, and easy to crack. [0004] If butyl rubber or hydrogenated nitrile rubber is used alone, the broad spectrum of protective chemicals is not wide, and it needs to be compo...
