In the Chinese market, there is an explosive growth in the number of young people choosing wallpaper when decorating. Currently, the main wallpaper composite adhesives on the market are solvent-based adhesives, water-based styrene-acrylic adhesives, and bio-based adhesives. Solvent-based adhesives contain a large amount of VOCs and other environmentally unfriendly factors, which are harmful to human health and will eventually be eliminated; water-based styrene-acrylic adhesives have poor aging resistance due to their benzene ring structure, which is not conducive to long-term product use, and the characteristics of acrylic hot melt and cold brittleness will cause inconvenience in transportation and construction in winter and summer; bio-based adhesives are prone to mold and mildew, especially during the rainy season in southern China, which will have an immeasurable impact on the entire home environment and human health.
Using aliphatic waterborne polyurethane as the main material for wallpaper composite adhesive, and modifying it with various environmentally friendly auxiliaries, has achieved good results. The specific process is as follows:
Materials: Thick paper, thin paper
Product: Waterborne polyurethane resin
Instruments: 30 micron wire rod, oven, hot press
