▎ 摘　　要

NOVELTY - Preparing composite grid cloth, comprises (i) drying the fiber mesh cloth made of interwoven fibers; (ii) mixing and stirring methyl cellulose ether, terpene resin, diallyl terephthalate, graphene powder and chloroprene rubber, and performing heat treatment to obtain the first glue solution and controlling the temperature of the first glue solution; (iii) completely immersing the dry fiber mesh cloth into the first glue solution controlled by constant temperature, and allowing the glue to dry; (iv) performing vacuum negative pressure treatment on the fiber mesh cloth after drying the glue; mixing tea polyphenols, ammonium polyphosphate, alkali lignin, polyethylene and urethane and stirring and heat-treating to obtain the second glue solution; and (v) coating the second glue solution on the surface of the fiber mesh cloth after vacuum negative pressure treatment, and drying. USE - The method is useful for preparing composite grid cloth. ADVANTAGE - The composite grid cloth has excellent flame retardant effect, high tensile strength, good high temperature resistance and good stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite mesh cloth.
