Embodiment 1
[0010] The present invention is a kind of wood adhesive, is made from the raw material of following parts by weight:
[0011] 2.5 parts of ammonium chloride, 0.8 parts of lactenamide, 1 part of aluminate waterproofing agent, 3 parts of potato starch, 3 parts of diatomaceous earth, 0.5 parts of 4-nonylphenol, 2.8 parts of polyamide polyamine epichlorohydrin resin and 1.2 parts of trioctyl citrate.
Embodiment 2
[0013] The present invention is a kind of wood adhesive, is made from the raw material of following parts by weight:
[0014] 4.2 parts of ammonium chloride, 1.6 parts of lactam, 1.8 parts of aluminate waterproofing agent, 8 parts of potato starch, 8 parts of diatomaceous earth, 1.6 parts of 4-nonylphenol, 4.6 parts of polyamide polyamine epichlorohydrin resin and 3.6 parts of trioctyl citrate.
Embodiment 3
[0016] The present invention is a kind of wood adhesive, is made from the raw material of following parts by weight:
[0017] 3.6 parts of ammonium chloride, 1.2 parts of lactam, 1.5 parts of aluminate waterproofing agent, 7 parts of potato starch, 6 parts of diatomaceous earth, 1.2 parts of 4-nonylphenol, 3.2 parts of polyamide polyamine epichlorohydrin resin and 2.4 parts of trioctyl citrate.
[0018] Compared with the existing products, the present invention has rich sources of starch as the main component, low price, and environmental protection, which ensures the low cost and cleanliness of the wood adhesive; the starch-based wood adhesive prepared by the present invention The bonding strength and water resistance can not only be compared with trialdehyde glue, but also solve the technical defects of the aldehyde toxic compounds brought by the trialdehyde glue used in the bonding of existing wood products to pollute the environment and endanger health; in addition, starch...

Abstract
The invention discloses a wood adhesive. The wood adhesive is prepared from the following raw materials in parts by weight: 2.5-4.2 parts of ammonium chloride, 0.8-1.6 parts of acrylamide, 1-1.8 parts of aluminate waterproofing agent, 3-8 parts of potato starch, 3-8 parts of diatomite, 0.5-1.6 parts of 4-nonyl phenol, 2.8-4.6 parts of polyamide polyamine epichlorohydrin resin and 1.2-3.6 parts of trioctyl citrate. Compared with the traditional product, the wood adhesive has the advantage that starch serving as a main component is rich in source, is low in cost and is environmentally friendly, thus ensuring low cost, cleanness and non pollution of the wood adhesive; adhesive strength and water resistance of the starch-based wood adhesive can be comparable with those of a three-formaldehyde resin adhesive, and the technical defects that environment is polluted and health is endangered due to toxic aldehyde compounds brought by the traditional three-formaldehyde resin adhesive used for adhesion in a wood product are also solved; the starch-based wood adhesive can be cured at room temperature and can also be widely applied to the field of splicing of wood-based panels and woods and the like.
Description
technical field [0001] The invention relates to a wood adhesive and belongs to the field of building materials. Background technique [0002] The three major types of glue used in the traditional wood processing industry: urea-formaldehyde resin, phenolic resin and melamine-formaldehyde resin, have the problem of releasing toxic aldehyde compounds during preparation, curing and use, which seriously pollute the environment and endanger human health. With the gradual enhancement of people's awareness of environmental protection and the improvement of national environmental protection laws and regulations, the development of non-toxic, non-polluting, green and environmentally friendly wood adhesives has become an inevitable trend in the development of the industry. Starch adhesive is a kind of cheap, non-toxic, natural environmental protection, green and renewable adhesive species. At present, it is mainly used in paper product bonding, label making, building mounting, decorati...
