NOVELTY - Preparing graphene-containing ultrafine materials and products involve making fiber A, B and C. The obtained fibers are mixed roughly for 1 time. The fibers are again mixed for 2 times. The fiber is snowflake shape. The snowflake-shaped fiber are used in a fiber wadding with a certain density. 86-88 pts. wt. fiber A comprises terylene, 4-4.5 pts. wt. fiber B comprises modified high-shrinkage terylene fibers and 4-6 pts. wt. fiber C comprises graphite fiber. Base cloth is prepared by weighing the fiber cotton wool. The old impurity is mixed in obtained mixture. USE - Method for preparing graphene-containing ultrafine materials and products used in special equipment, such as for protection, military shoes, apparel and equipment. ADVANTAGE - The method enables to prepare graphene-containing ultrafine materials and products that have high elasticity and toughness. DETAILED DESCRIPTION - Preparing graphene-containing ultrafine materials and products involve making fiber A, B and C. The obtained fibers are mixed roughly for 1 time. The fibers are again mixed for 2 times. The fiber is snowflake shape. The snowflake-shaped fiber are used in a fiber wadding with a certain density. 86-88 pts. wt. fiber A comprises terylene, 4-4.5 pts. wt. fiber B comprises modified high-shrinkage terylene fibers and 4-6 pts. wt. fiber C comprises graphite fiber. Base cloth is prepared by weighing the fiber cotton wool. The old impurity is mixed in obtained mixture. The obtained product is needed positively and negatively to form three-dimensional fiber net. The three-dimensional fiber net is paved under the woven fabric, so that the three-dimensional fiber mesh and woven fabric composite into microfiber composite nonwoven fabric. The obtained product is carried out with polyvinyl alcohol impregnation treatment. The base cloth is prepared with dipping roller. The mass concentration of polyvinyl alcohol solution is 6-9 wt.%. The impregnation treatment is carried out by dipping base cloth in a polyurethane slurry. The obtained product is washed with normal temperature water. The obtained product is dried and shaped. The condensing liquid is dimethyl formamide. The obtained product is carried out with alkali decrement treatment. The obtained product is dry laminated. The surface layer slurry is coated on the carrier. The sizing agent is coated on the carrier. The sizing agent comprises graphene and protein powder to form bottom layer. The adhesive layer is coated on the bonding layer. The obtained product is cooled. Surface layer slurry comprises 88-90 pts. wt. first polyurethane resin, 65-75 pts. wt. solvent, 3.5-6.5 pts. wt. flame retardant, 90-110 pts. wt. antistatic filler and 1.5-2.5 pts. wt. protein powder. The middle layer slurry comprises 88-90 pts. wt. second polyurethane resin, 45-55 pts. wt. solvent, 3.5-6.5 pts. wt. flame retardant, 90-110 pts. wt. antistatic filler and 1.5-2.5 pts. wt. protein powder. Bottom layer slurry comprises 88-90 pts. wt. second polyurethane resin, 3.5-6.5 pts. wt. flame retardant, 1.5-2.5 pts. wt. graphene filler and 1.5-2.5 pts. wt. protein powder. The bonding layer paste comprises 88-90 pts. wt. third polyurethane resin, 38-45 pts. wt. solvent, 3.5-6.5 pts. wt. flame retardant, 2.5-3 pts. wt. curing agent, 0.8-1 pts. wt. catalyst and 90-110 pts. wt. antistatic filler.
