[0011] 2.3 parts of soybean meal, 4.5 parts of soybean protein, 3.2 parts of renewable disperse latex powder, 1.2 parts of phthalates, 2.5 parts of rosin, 0.5 parts of paraformaldehyde, 1 part of alkali lignin and 1.2 parts of amidopolyamine resin.
Embodiment 2
[0013] The invention is a novel wood adhesive, which is made from the following raw materials in parts by weight:
[0014] 4.2 parts of soybean meal, 8.5 parts of soybean protein, 4.8 parts of renewable dispersible latex powder, 2.6 parts of phthalates, 4.2 parts of rosin, 1.5 parts of paraformaldehyde, 2.3 parts of alkali lignin and 2.4 parts of amidopolyamine resin.
Embodiment 3
[0016] The invention is a novel wood adhesive, which is made from the following raw materials in parts by weight:
[0017] 3.6 parts of soybean meal, 6.5 parts of soybean protein, 4.2 parts of renewable dispersible latex powder, 2.3 parts of phthalates, 3.8 parts of rosin, 0.8 parts of paraformaldehyde, 1.5 parts of alkali lignin and 1.8 parts of amidopolyamine resin.
[0018] Compared with the existing products, the present invention can bond wood and various wood-based panels, no formaldehyde is released in the process of production and use, and will not cause health damage caused by formaldehyde to workers and consumers; the environment after normal production and gluing The dehydration time is more than 120 minutes at a temperature of 30 degrees Celsius, which can fully meet the domestic production needs; the adhesive has a high viscosity, is easy to apply evenly, has a high solid content, and has a good cold pressing effect. Store for a long time.
