Abstract

The invention relates to the technical field of acrylic emulsions, and particularly relates to a self-crosslinking acrylic emulsion and a preparation method thereof. The self-crosslinking acrylic emulsion is prepared from the following raw materials in parts by weight: a component A, namely 130-150 parts of crylic acid solid resin, 350-450 parts of water and 40-60 parts of ammonium hydroxide or monoethanolamine or triethanolamine, a component B, namely 5-12 parts of an emulsifier and 15-25 parts of water, a component C, namely 1-3 parts of persulfate and 5-12 parts of water, a component D 1, namely 85-95 parts of methyl methacrylate and 70-80 parts of ethyl acrylate, a component D 2, namely 85-95 parts of methyl methacrylate and 70-80 parts of ethyl acrylate, a component E, namely 0.8-1.5 parts of persulfate and 5-15 parts of water, a component F, namely 5-12 parts of diacetone-acryloamide and 25-35 parts of water, and a component G, namely 2-5 parts of adipic dihydrazide and 25-35 parts of water. The self-crosslinking acrylic emulsion does not contain a toxic solvent, so that the VOC content is low; and the self-crosslinking acrylic emulsion does not contain TDI and various heavy metals, so that the self-crosslinking acrylic emulsion is environment-friendly and safe, has the advantages of relatively good levelling property and film surface smoothness, shows a bright effect after forming a film, and is free of a white scar or dusting when rubbed and kneaded.

Description

technical field [0001] The invention relates to the technical field of acrylic emulsion, in particular to a self-crosslinking acrylic emulsion and a preparation method thereof. Background technique [0002] In the field of paper processing, self-crosslinking acrylic emulsion is used on the surface of paper to enhance the feel and appearance of printed matter, improve the durability, quality and grade of paper, and make the printed matter beautiful and generous, with high brightness, and waterproof and solvent-proof, etc. Features, widely used in printing and packaging industry, is an important form of paper packaging. At present, the self-crosslinking acrylic emulsion used in the market has some defects in use, mainly manifested in the phenomenon of damage to printed products due to cleaning with white electric oil in post-processing of paper products, resulting in a lot of loss and waste . Moreover, some existing self-crosslinking acrylic emulsions contain toxic solvents,...
