Abstract

The invention discloses a novel non-formaldehyde environment-friendly adhesive and a preparation method. The novel non-formaldehyde environmentally-friendly adhesive is formed by proportionately charging, cross-linking and polymerizing sclerotin protein, sodium hydroxide, sodium benzoate and catalysts, and has the characteristics of water resistance, weather resistance, mould prevention, environmental friendliness, and the like. The formaldehyde release amount of a special decorative board manufactured by using the adhesive is only 0.1mg / L, which is lower than 0.5mg / L required by a national standard as well as 0.2mg / L required by European and American standards, so that the novel non-formaldehyde environment-friendly adhesive can be widely applied to woodwork industries such as artificial boards, furniture and composite floors.

Description

Technical field: [0001] The invention relates to a novel formaldehyde-free environmentally friendly adhesive and a preparation method thereof, which can be widely used in wood-based panels, furniture, composite floors and other wood product industries, and has the characteristics of water resistance, weather resistance, mildew resistance, and environmental protection. Background technique: [0002] At present, "trialdehyde glue" is the main adhesive used in my country's wood product industry, accounting for more than 85% of the adhesive used in the entire wood product industry. However, this type of synthetic resin adhesive will continuously release formaldehyde during production and use, causing environmental pollution. Harmful to human health. In recent years, with the expansion of the adhesive market, people have paid more and more attention to the problem of environmental pollution. The requirements for environmental protection are getting higher and higher, and the deman...
