Problems solved by technology

However, the heat resistance, solvent resistance and weather resistance of the polyacrylate coating film are poor, and there are disadvantages such as high hardness, cold and brittle hot stickiness, etc. The fabric treated with this type of adhesive has poor rubbing fastness, hard hand feeling, Formaldehyde release and other issues
[0004] In order to solve the shortcomings of polyacrylate adhesives, many researchers have carried out organosilicon modification, as disclosed in the publication number CN105601799 A core / shell type organosilicon modified acrylate emulsion and its preparation method and application. The organosilicon monomer used is γ-methacryloxypropyltrimethoxysilane. The organosilicon monomer has a small molecular weight, which can make up for the structural shortcomings of polyacrylate to a certain extent, but it does not help to improve the feel. In addition, the Si-O-C bond in this structure is easily hydrolyzed, which affects product stability and use effect
Publication No. CN 103526595 A discloses an imitation active pigment printing adhesive and its preparation method. The silane coupling agent KH-570 used is easily hydrolyzed after being polymerized with acrylate. The modification of methacrylamide improves the hydrolysis of acrylate, but the Si-O-C in the product will still be hydrolyzed, affecting the stability

Abstract

The invention discloses an imitated activated pigment printing adhesive copolymer and a preparation method thereof. The copolymer is prepared from 5-25 wt% of organosilicone copolymerization units containing unsaturated carbon-carbon double bonds, 15-35 wt% of hard monomer copolymerization units containing unsaturated carbon-carbon double bonds, 45-70 wt% of soft monomer copolymerization units containing unsaturated carbon-carbon double bonds, 0.5-5 wt% of crosslinking monomer copolymerization units, 0.5-5 wt% of functional monomer copolymerization units capable of being bonded with cellulose and 0.5-5 wt% of organic carboxylic acid copolymerization units containing unsaturated carbon-carbon double bonds based on the total weight of the imitated activated pigment printing adhesive copolymer. The adhesive product is not likely to be hydrolyzed and good in stability, has excellent crockfastness and hand feeling and achieves an imitated activated pigment printing effect.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to an environmental-friendly imitation active pigment printing adhesive copolymer and a preparation method thereof. Background technique [0002] Pigment printing refers to the process of using adhesives to adhere paint that has no affinity and reactivity to fabrics on fabrics. Pigment printing only needs to fix the color without washing, which can significantly shorten the process flow, save energy and reduce emissions. Therefore This process is widely adopted by the printing and dyeing industry. [0003] Polyacrylate emulsion is cheap and easy to obtain, and has excellent coating performance, and has been widely used in the field of pigment printing. However, the heat resistance, solvent resistance and weather resistance of the polyacrylate coating film are poor, and there are disadvantages such as high hardness, cold and brittle hot stickiness, etc. The f...
