Abstract

The invention belongs to the technical field of chemical engineering and particularly relates to special waterborne acrylic resin for wallpaper as well as a preparation method of the special waterborne acrylic resin. The special waterborne acrylic resin for wallpaper is prepared from the following raw materials in parts by weight: 100 parts of a monomer, 0.3-3 parts of an anionic emulsifier, 0.1-1.5 parts of a nonionic emulsifier, 0.1-5 parts of an initiator, 0.1-5 parts of a pH value adjustor, 150-300 parts of softened water and 0.1-0.2 part of aluminum dihydrogen phosphate. The waterborne acrylic resin produced by a low-temperature polymerization method thoroughly solves the problem that the existing acrylic emulsion for wallpaper is sticky when the TG value is -20 DEG C and the roller is sticky in the coating process of the wallpaper, so that latex is not sticky to the roller in the production application process. Wallpaper is mostly used for home decoration with considerably important environmental requirements. The wallpaper latex prepared is free of VOC and is environmental-friendly as compared with currently used formaldehyde-phenolic resin, urea resin, modified starch glue and styrene-butadiene latex.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a special water-based acrylic resin for wallpaper and a preparation method thereof. Background technique [0002] Wallpaper, also known as wallpaper, English is Wallpaper or Wallpaper, it is a widely used interior decoration material. Because wallpaper has various colors, rich patterns, safety and environmental protection, convenient construction, reasonable price and many other characteristics that other interior decoration materials cannot match. [0003] China's wallpaper market has huge potential, attracting famous wallpaper manufacturers from abroad. Since the 1990s, international wallpaper companies have set up camps in China. They either use agents or promote their products in the form of brands. In the "competition" with foreign companies, leading domestic wallpaper companies began to imitate, learn, and improve the culture, products, and business ...
