Abstract

The invention discloses a fluorine-containing fabric waterproof agent. The fluorine-containing fabric waterproof agent is composed of, by mass, 6-14% of perfluoroalkylethyl acrylate, 9-17% of acrylic resin, 9-13% of octamethyl tetrasiloxane, 1-5% of carboxymethylcellulose, 5-13% of polyvinyl alcohol, 1-9% of cross-linked monomer, 0.2-0.5% of surfactant, 0.5-0.9% of initiator and 60-70% of deionized water. The invention further discloses a preparation method of the fluorine-containing fabric waterproof agent. The preparation method includes: mixing the surfactant with the deionized water to obtain obtain a surfactant water solution; adding perfluoroalkylethyl acrylate, the acrylic resin, octamethyl tetrasiloxane, carboxymethylcellulose and the cross-linked monomer into the surfactant water solution to form mixed liquid; mixing polyvinyl alcohol and the initiator with the mixed liquid, and filtering to obtain the waterproof agent. The fluorine-containing fabric waterproof agent is capable of making fabric soft, durable, waterproof and oil-proof.

Description

technical field [0001] The invention relates to a fluorine-containing fabric waterproofing agent, and also relates to a preparation method of the above-mentioned fluorine-containing fabric waterproofing agent. Background technique [0002] Usually, in the process of chemical fiber weaving and pretreatment, many factors may cause the fabric to feel rough. At this time, it is often necessary to add a softener to give the fabric a soft feel. [0003] Softener is a daily chemical product that can give clothes and fabrics a soft and pleasant feeling in hand, wearing and use. After the softener is adsorbed on the surface of the fiber, it can prevent the direct contact between the fiber and the fiber, reduce the dynamic friction coefficient and the static friction coefficient between the fiber and the fiber, so as to achieve the effect of soft, smooth and comfortable to wear. [0004] However, most of the existing softeners have the problems of high cost, single performance and po...
