Problems solved by technology

[0002] Fluorine rubber has excellent physical and mechanical properties, medium resistance and high temperature resistance, but its processing performance is poor
Fluorine rubber-coated fabrics are often used in the field of chemical protection. Protective clothing made of fluororubber-coated fabrics will have poor bonding strength during processing, so "sewing + cold bonding" is often used in the processing of protective clothing Due to the sewing process, there is a greater safety hazard to the airtightness of the protective clothing; at the same time, because the adhesive layer has no inner fabric layer, it also has a greater impact on the wearing comfort of the wearer.
[0003] Therefore, the existing chemical-resistant adhesive plasters can no longer meet the needs in terms of the processing of protective clothing and the wearing comfort of personnel.

Abstract

The invention discloses a rubberized fabric material with a polyester cotton lining and capable of preventing chemical penetration. The rubberized fabric comprises base cloth, wherein two side surfaces of the base cloth are respectively coated with a fluororubber layer and a chlorobutyl rubber layer; polyester cotton cloth is compounded outside the fluororubber layer. According to the rubberized fabric material, the polyester cotton cloth is laminated to the fluororubber layer, so that the bonding strength of the rubberized fabric is improved; the two surfaces of the base cloth are respectively coated with fluororubber and chlorobutyl rubber; the one layer of polyester cotton cloth is laminated to the fluororubber layer; after drum type primary vulcanization, secondary vulcanization is performed in a vulcanizing tank, and thereby a finished product is obtained. Compared with the prior art in China, the rubberized fabric material has the advantages that the bonding strength of the rubberized fabric is improved while physical and mechanical properties, medium resistance and protecting performance are prevented from being reduced.
