Abstract

The invention provides a durable, waterproof, oil-proof, antistatic and antibacterial functional coating adhesive and a preparation method. The coating adhesive is prepared from methyl acrylate, n-butyl acrylate, glycidyl methacrylate, allyl methacrylate, 2,2,2-trifluoroethyl methacrylate, acryloyloxyethyl trimethyl ammonium chloride, fatty alcohol polyoxyethylene ether XL90, hexadecyl trimethyl ammonium chloride, 2,2-azobis(2-methylpropionamidine)hydrochloride, deionized water and an associative polyurethane levelling and rheological agent WT-203 through the processes of emulsification, initiated polymerization and thickening.

Description

technical field [0001] The invention relates to a textile post-finishing functional coating glue, and the textiles processed with this glue coating have the main characteristics of durable waterproof, oil-proof, antistatic and antibacterial. Its technical feature is that the main glue molecule of the coating glue contains multiple -CF3 groups, and is in the outer layer of the polymer chain, so it has good hydrophobicity and oil repellency, and has excellent waterproof, oil, and stain resistance; the main glue molecule There are also trimethylammonium chloride cationic groups in the structure, which can provide excellent antistatic and antibacterial effects. Background technique [0002] In the prior art, in order to realize the waterproof, oil-proof, antistatic and antibacterial effects of the textile fabrics, it is realized through the padding process of the finishing agent, and its poor washing resistance is a recognized shortcoming. [0003] In recent years, the demand f...
