Abstract

The invention discloses a stiffening agent for core-shell silicone modified polyacrylate. The stiffening agent is formed by emulsion polymerization of vinyl monomer and vinyl silicone oil, and the quality of vinyl silicone oil accounts for 1-5% of the total mass of vinyl monomer and vinyl silicone oil; the vinyl monomer contains at least acrylate monomer Body, which obtains core-shell silicone modified polyacrylate, which has good film-forming properties and strong adhesion. In emulsion polymerization, dimethyl diallyl ammonium chloride and ethylene glycol diacrylate are used as network crosslinking agents, which can effectively increase the average molecular weight of the polymer and ensure the finishing and stiffness of the obtained emulsion. At the same time, it provides a rich feel; vinyl silicone oil can also impart smoothness, cationic emulsifiers and cationic initiators ensure the weak cationic type of the emulsion, and even make the overall emulsion show a performance close to non-ionic, so as to achieve the same effect as silicone smoothing agents better compatibility.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a stiffening agent for core-shell type organosilicon-modified polyacrylate and a preparation method thereof. Background technique [0002] Ordinary stiffeners, such as polyvinyl acetate white glue resin, although the fabrics treated with it have better stiffness and richer hand feeling, they are brittle, have poor frost resistance, are not washable, and become soft after a long period of storage , and is an anionic type, it cannot be used in the same bath with silicone emulsion, especially amino silicone oil emulsion system. It needs to be shaped twice, which wastes time and energy. Etherified hexamethylolmelamine resin has good stiffness, shrinkage, elasticity and hand feeling after finishing. However, after finishing, the fabric is easy to absorb moisture, the hardness decreases, it will turn yellow and its strength will decrease, and it will release fr...
