Description
Technical Field
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
The existing butyl nylon lining gloves are made by dipping a single rubber type, namely butyl, as a main material. The butyl rubber has the best air tightness in rubber and has certain chemical corrosion resistance. The disadvantage is that butyl rubber has a poor tolerance to petroleum solvents, coal tar and aromatics, etc.
