Abstract
The invention discloses a modified acrylate foam coatingemulsion and a preparation method thereof. The modified acrylate foam coatingemulsion comprises the following raw materials in parts by weight: 11-11.5 parts of heterogeneous 13-carbon fatty alcohol polyoxyethylene (40) ether, 1-1.3 parts of lauryl sodiumsulfate, 3.5-3.8 parts of acrylic amide, 7-7.3 parts of beta-acyloxy propionic acid, 0.4-0.6 parts of hydroxyethyl methylacrylate, 1.5-1.7 parts of isocyanatoethyl methacrylate, 98-110 parts of ethyl acrylate, 94-105 parts of butyl acrylate, 18-21 parts of methyl methacrylate, 18-20 parts of styrene, 2-2.2 parts of ammoniumpersulfate, 1-1.1 parts of sodiumhydrogensulfite and 275-312 parts of deionized water. The polymeremulsion is formed through seed emulsion polymerization. The modified acrylate foam coating emulsion is especially applicable to arrangement of cotton, polyester and polyester fabric foaming coatings, has soft handfeeling and good elasticity, is breathable, cold-resistant and excellent in fastness.
Description
technical field [0001] The invention relates to a foam coating emulsion for textiles and a preparation method thereof, which is a polyurethane-modified acrylic polymer emulsion. It is especially suitable for foam coating finishing of cotton, polyester cotton and polyester fabrics. Background technique [0002] Foam coating is a finishing technology for textiles. Fabrics finished with foam coating are waterproof, breathable and moisture permeable, and improve the fabric feel. Flame retardant, anti-fouling treatment agent, UV absorber, antistatic agent, etc. can also be added to the foam coating emulsion to achieve flame retardant, anti-fouling, anti-ultraviolet, antistatic and other properties. Moreover, the foam coating has the advantages of saving dyeing agents, saving energy and reducing processing costs. [0003] Since the beginning of the 21st century, with energy shortages and lack of water resources, people's awareness of environmental protection has been greatly enh...
