Abstract

The invention discloses a waterproof finishing agent and a use thereof. The waterproof finishing agent comprises, by weight, 10-20 parts of methanol, 40-60 parts of a fluorine-containing boronic acid derivative, 4-8 parts of sodium aliphatate, 5-10 parts of polyethylene wax emulsion, 4-8 parts of an organosilicon, 1-3 parts of a surfactant and 200 parts of water. The fluorine-containing boronic acid derivative is one of 2-trifluoromethylphenylboronic acid, 3-trifluoromethylphenylboronic acid, 4-trifluoromethylphenylboronic acid, 4-trifluoromethoxyphenylboronic acid, 3, 5-bis(trifluoromethyl) derivative and 3, 4, 5-trifluorophenylboronic acid. The fluorine-containing boronic acid derivative is used as a main raw material of the waterproof finishing agent. Through a common double-padding-double-dipping production technology and coordination complexation, a fabric is treated by the waterproof finishing agent. The treated fabric has good waterproofness and retains original fastness to washing and whiteness so that the waterproof finishing agent has a practical application value and a wide application prospect in the field with self-cleaning requirements.

Description

technical field [0001] The invention belongs to the field of textile waterproofing, and in particular relates to a waterproof finishing agent and its application. Background technique [0002] Along with the fast development of world economy, the raising of people's living standard, textile cloth has become people to prepare the indispensable daily necessities such as clothes, carpet, curtain, and textile in the prior art is generally made by cotton fiber or polyester fiber, generally not It is waterproof. After the textile fabric without waterproof treatment absorbs water and sweat, the water and sweat penetrate into the back of the fabric, affecting the appearance and comfort of the fabric, which limits its application in daily life and in special climates and special environments such as rainy days, summer days, high temperatures, and the wild. . Some waterproof fabrics in the prior art are provided with thicker leather and other materials on the outer layer, which are ...
