▎ 摘  要

NOVELTY - Producing radiation-proof cloth, comprises (a) impregnating fabric in carboxy functional solution including carboxy group-containing solution, phenylacetic acid solution and dimethylformamide solution in volume ratio of 7:8:2-3 for 30-100 minutes, (b) adding graphene powder and dimethyl formamide solution, ultrasonic dispersing for 30-60 minutes, and (c) immersing the pretreated fabric base layer in dispersed graphene solution, dipping for 60-120 minutes by one-dipping-two-rolling process method. USE - The cloth is useful in preparation of graphene (claimed). DETAILED DESCRIPTION - Producing radiation-proof cloth, comprises (a) impregnating fabric in carboxy functional solution including carboxy group-containing solution, phenylacetic acid solution and dimethylformamide solution in volume ratio of 7:8:2-3 for 30-100 minutes, (b) adding graphene powder and dimethyl formamide solution, ultrasonic dispersing for 30-60 minutes, (c) immersing the pretreated fabric base layer in dispersed graphene solution, dipping for 60-120 minutes by one-dipping-two-rolling process method, (d) removing the fabric base, adding sodium alkylbenzene sulfonate and arabic gum into the immersion solution, uniformly stirring, and coating on the cloth base layer, (e) removing dimethylformamide, placing the wet product at 60-70 degrees C and pressure of 7-10 mbar for 10-20 minutes, and (f) drying the wet product.
