Abstract

The invention discloses a graphene waterproofing agent for textile use. The graphene waterproofing agent is prepared from the following raw materials: a modified graphene material, silicon dioxide, resin, a surfactant, an auxiliary agent and water. Preferably, the waterproofing agent is prepared from the following raw materials in percentage by mass: 0.5-5% of the modified graphene material, 1-6%of the silicon dioxide, 13-60% of the resin, 0.5-8% of the surfactant, 2-10% of the auxiliary agent and the balance of water. The surfactant is a cationic surfactant. The auxiliary agent comprises aninitiator and a thickener; and the weight ratio of the initiator to the thickener is (1: 1)-(5: 3). The initiator comprises persulfate and / or oil-soluble azo. The thickener comprises any one or more of diatomite, ammonium polyacrylate, polyvinyl alcohol and polyurethane. According to the graphene waterproofing agent, the graphene is blended into each component of the waterproofing agent, so that the obtained waterproofing agent has excellent waterproof performance, and meanwhile, the problems of low tensile property and fiber damage of the fabric after the waterproofing agent is used can be solved.

Description

technical field [0001] The invention relates to a graphene waterproofing agent, in particular to a graphene waterproofing agent for textiles. Background technique [0002] Textile waterproofing agent is a product used for functional finishing of textile fabrics. It has a wide range of applications and involves various fields of textiles. There are also many types of products. The same product can be used for different fabrics, and different products can give fabrics different properties. performance. According to the performance, textile waterproofing agent can be mainly divided into four aspects: waterproof, oil-proof, anti-fouling and easy to decontaminate. After finishing with different textile waterproofing agents, the above four properties can be given to textiles. [0003] Graphene is a single-layer carbon atom material peeled off from graphite. Carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. It is the thinnest, hardest...
