Abstract

The invention discloses a water-based nonionic acrylic resin, which is prepared from the following raw materials in parts by weight: 35-55 parts of ethyl acrylate, 50-100 parts of deionized water, 0.35-1.6 parts of an initiator, and a cross-linking monomer. 0.2-0.4 part, 0.2-0.6 part of monobutyl itaconic acid, 0.2-0.6 part of diisooctyl maleate, 0.08-0.2 part of octadecyl methacrylate, 0.1-0.5 part of emulsifier, pH adjustment 0.3-0.6 parts of acrylic acid, 0.4-0.6 parts of acrylic acid, and 2-6 of ethylene glycol. Also disclosed is a preparation method of the above-mentioned water-based nonionic acrylic resin, which has short reaction time and relatively simple process. The film of the produced water-based acrylic resin is transparent, soft to the touch and natural in color.

Description

technical field [0001] The invention belongs to the field of polymer material synthesis, and in particular relates to a water-based nonionic acrylic resin and a synthesis method thereof. Background technique [0002] With the development of society and the continuous improvement of people's living standards, the requirements for leather products are getting higher and higher. Natural color, natural feel and real leather texture are necessary for the leather products that people are looking for now. [0003] Cationic polyurethane resin for leather is thin and soft to the touch. Leather coated with a series of cationic polyurethane resins has natural color, soft touch, transparent film formation, and can highlight the leather texture. However, cationic polyurethane resin is basically imported from abroad, and the price is particularly high, which adds a lot of cost to leather manufacturers. In this case, it is necessary to develop a non-ionic acrylic resin. [0004] Chines...
