Abstract

The invention discloses a silicon-containing fluorine-free water repellent copolymer emulsion for fabrics and a polymerization method thereof, which contains the following components, long-chain alkyl acrylate, functional monomers and the general formula CH 2 =CX 1 C(C=O)‑O‑R 1 -Si(X 2 )(X 3 )X 4 Represented terminal methyl polysiloxane alkyl acrylate, where, X 1 is a hydrogen atom or a methyl group, R 1 is C2‑C6 alkylene, X 2 , X 3 , X 4 The general formula is –(O‑Si(CH 3 ) 2 ) n CH 3 The terminal methyl polydimethylsiloxane group, n is an integer of 0-6, X 2 , X 3 , X 4 may be the same or different groups. The silicone-containing fluorine-free waterproofing agent copolymer emulsion for fabric can improve the hand feeling of the fabric treated with the waterproofing agent, and eliminate the defect of fabric scratches.

Description

Technical field: [0001] The invention relates to the field of waterproofing agents, in particular to a silicone-containing fluorine-free waterproofing agent copolymer emulsion for fabrics and a polymerization method thereof. Background technique: [0002] The traditional waterproof and oil-repellent agent for fabrics is a copolymer emulsion of perfluoroalkyl ethyl acrylate (methyl), while the new generation of environmentally friendly fabric waterproofing agent requires no fluorine-containing components, which are called fluorine-free waterproofing agents. One of the common components of fluorine-free water repellent is long chain alkyl acrylate copolymer, which generally does not contain silicone components. This single long-chain alkyl copolymer emulsion has the following problems: 1. It feels hard, and the fabrics treated with fluorine-free water repellent are prone to scratches; 2. The washability of cotton fabrics is relatively low, and the waterproof effect after washi...
