Single-component emulsion organic silicon performed polymer self-cross-linked water-proof finishing agent and its preparation

Abstract

This invention publics a monocomponent emulsion preorganosilicon aggressiveness self crosslinking waterproof finish acidifier,of which the constituent includes silicon dioxide, hydrogen -silicone oil, functional organosilicon and surface modifier. The invention also publics the method preparing waterproof finish agent, which includes: first surface modify silicon dioxide, make silicon dioxide and hydrogen -silicone oil into performed polymer, then functional graft, in the end add emulsifying agent for emulsification. Waterproof finish produced by the this method equals fluor-finishing agent in waterproof effect, and is of low cost, so it's prospect application is good.

Description

technical field [0001] The invention belongs to the field of textile industry and relates to a waterproof finishing agent. Furthermore, the invention relates to a self-crosslinking waterproof finishing agent of a single-component emulsion organic silicon prepolymer made of silicon dioxide. Background technique [0002] With the continuous development of the domestic textile industry, the international textile processing is also increasingly transferred to the domestic, so the requirements for finishing and processing after textile are getting higher and higher. Water-repellent finishing has been widely used as a functional finishing agent for bags, raincoats, parasols and casual outerwear. [0003] There are two main types of water-repellent finishing agents: one is fluorine-containing materials, and the other is silicone materials. Fluorine-containing finishing agents, such as fluorine-containing acrylates, have the characteristics of large contact angle and high degree of...
