Abstract

The invention relates to the technical field of woodwork processing, and discloses a woodwork environmentally-protective waterproof adhesive. The woodwork environmentally-protective waterproof adhesive comprises the following raw materials: fish scale protein, konjac polysaccharide, seaweed powder, vinyl resin, itaconic acid, nano zinc oxide, dibutyl phthalate, tributyl phosphate, polyvinyl alcohol and polyoxyethylene nonyl phenyl ether. The environmentally-protective waterproof adhesive has the advantages of simple preparation, little application amount, safety and no toxicity, delicate fragrance and no peculiar smell, convenient usage, water resistance and durability, and can reach I-class waterproof requirement, the dry state bonding strength is 2.73 MPa; the fish scale is added for protein extraction, so that the waste is changed into valauables, the environment is protected, economic income of fish-farming peasant is increased, production cost of the adhesive is reduced, the deep processing approach of the fish scale is increased; konjak polysaccharide and seaweed powder are added, which are environmentally-protective and no toxic, can increase fragrance, increases bonding strength of the adhesive, so that the adhesive has the characteristics of water retention and water resistance, can be directly used while being opened, can keep the bonding strength, has abundant raw materials, and can increases the flexibility and processing performance of the woodwork after smearing and drying, and is antibacterial and antifungal.

Description

technical field [0001] The invention mainly relates to the technical field of wood product processing, in particular to an environmentally friendly waterproof adhesive for wood products. Background technique [0002] A large amount of adhesives are used in the production of wood products to connect different products and materials together through interface adhesion and cohesion. Adhesives used in the wood processing industry account for about 60% of the total adhesives each year. At present, the special adhesives for wood products on the market are "trialdehyde glues", that is, urea-formaldehyde glue, phenolic glue, melamine-formaldehyde glue, "three-formaldehyde glue" "Aldehyde glue" has limited raw materials and is non-renewable, and it will release the first type of carcinogen free aldehyde, which seriously endangers the environment and human health. Wood products are very easy to absorb water during use, which is easy to cause degumming and cracking, which will adverse...
