Problems solved by technology

[0004] Therefore, the balance between water repellency and easy decontamination requires that the surface energy of the material changes with the environment. A fluorine-free water repellent with a three-dimensional silane structure is disclosed in Chinese patent CN106810650B. The invention also discloses a high-efficiency hydrophobic The POSS structural monomer is studied. The POSS structural monomer itself has low surface energy and good mobility as a side chain. It is a new type of organic-inorganic hybrid monomer tha

Abstract

The invention discloses a fluoride-free water-repellency stain-release multifunctional finishing agent and a preparation method and application thereof. The fluoride-free water-repellency stain-release multifunctional finishing agent is a waterborne emulsion or waterborne solution of a polymer shown in a formula I. The structural formula of the polymer is shown in the formula I, and in the formulaI, R1 is a long-chain acrylate or long-chain methacrylate structure chain segment; R2 is a cage type silsesquioxane structure chain segment containing a mono-acrylate group or a mono-methacrylate group; R3 is a polyethylene glycol methanal structure chain segment containing a mono-methacrylate structure or a mono-acrylate structure; R4 is a structure chain segment of a functional monomer and is selected from an acrylate or methacrylate monomer containing at least one of hydroxyl, an epoxy group, an amide group, dimethylamino, carboxyl, an ester group, an alkoxy, a blocked isocyanate group anda halogen end group, and a, b, c and d represent the degrees of polymerization. The finishing agent is environmentally friendly, capable of removing stains easily, free of biologic toxin and not degradable; preparation is easy, and conditions are mild.

Description

technical field [0001] The invention relates to a fluorine-free, water-repellent, easy-to-decontamination multifunctional finishing agent, a preparation method and application thereof. Background technique [0002] Decontamination-removing finishing agents are widely used as a functional auxiliary in the textile industry. In terms of performance, decontamination-removing finishing agents include hydrophilic and decontamination-removing finishing agents and water-repellent and decontamination-removing finishing agents. Among them, hydrophilic and easy-to-decontamination finishing agents are usually divided into anionic hydrophilic and easy-to-decontamination finishing agents, which are generally composed of vinyl polymers containing hydrophilic carboxylic acids and vinyl or acrylate-based monomers containing carboxylic acids such as Acrylic acid, methacrylic acid and maleic anhydride are copolymerized and hydrolyzed; the other is non-ionic hydrophilic and easy-to-decontaminat...
