Abstract

The invention discloses a waterproof agent for fabrics. The waterproof agent comprises the following components: epoxy silicone oil modified vinyl / amino-functional silicone emulsion, carboxyl modified vinyl / amino silicon oil, amino-functional silicone emulsion, hydrogen-containing silicone emulsion and deionized water. The invention also relates to a preparation method of the waterproof agent for the fabrics; the method comprises the step of evenly mixing the epoxy silicone oil modified vinyl / amino-functional silicone emulsion, the carboxyl modified vinyl / amino silicon oil, the amino-functional silicone emulsion, the hydrogen-containing silicone emulsion and the deionized water at the mixing speed of 150-250r / min to obtain the waterproof agent for the fabrics. The waterproof agent for the fabrics is good in waterproofness, elasticity and hand feeling, has good softness, crease resistance and air permeability, and is non-toxic, odorless, free of skin irritation and harmless to the environment; furthermore, the preparation method of the waterproof agent for the fabrics is simple and easy to implement and high in safety during preparation, and does not cause environmental pollution.

Description

technical field [0001] The invention belongs to the field of textile auxiliaries, and in particular relates to a fabric waterproofing agent and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of social life, people's living standards have also improved, and the requirements for clothing, food, housing and transportation have also become higher and higher. For wearing, people not only require clothing to have functions such as body covering and heat preservation, but also require clothing to have functions such as comfort, moisture permeability, perspiration, anti-wrinkle, waterproof and oil-proof, easy to decontaminate, UV protection, and antistatic. [0003] Traditional waterproof finishing agents are mainly fluorocarbons, which have a certain degree of bioaccumulation, serious ecological problems, and are expensive. Therefore, more and more researches focus on new fluorine-free waterproof finishing agents. Silicone ...
