[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.

Abstract
The invention discloses a novel wood adhesive, which is prepared from the following raw materials in parts by weight: 2.3 to 4.2 parts of soybean meal, 4.5 to 8.5 parts of soybean protein, 3.2 to 4.8 parts of renewable dispersed latex powder, 1.2 to 2.6 parts of phthalate, 2.5 to 4.2 parts of rosin, 0.5 to 1.5 parts of paraformaldehyde, 1 to 2.3 parts of alkali lignin, and 1.2 to 2.4 parts of amide polyamine resin. Compared with the conventional products, the provided wood adhesive can be used to bind wood and various artificial plates; during the production and application process, no formaldehyde is released, thus users and workers will not be hurt by formaldehyde; the water loss time is at least 120 minutes at an environment temperature of 30 DEG C after the adhesive is painted, the domestic production needs can be totally met; and the adhesive also has the advantages of large viscosity, convenience in painting, uniform coating, high solid content, and good cold pressure effect. After modification reactions, the adhesive can be stored at a room temperature of 20 DEG C for a long time.
Description
technical field [0001] The invention relates to a novel wood adhesive, which belongs to the field of building materials. Background technique [0002] At present, the adhesives used in the wood industry are still dominated by "trialdehyde glue" (urea-formaldehyde resin, phenolic resin, melamine-formaldehyde resin). However, aldehyde-based adhesives and their products will release formaldehyde during use. Formaldehyde has become one of the main indoor pollutants, seriously threatening people's physical and mental health. In addition, some raw materials of aldehyde-based adhesives come from non-renewable resources, so it is necessary to develop new adhesives when the resources are gradually exhausted. Protein glue is one of the oldest adhesives, but due to the different raw materials of protein, the produced protein glue is also very different. With the continuous advancement of technology, in recent years, in the development of "natural vegetable glue", two categories of "...
