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.
