Abstract

The invention relates to the technical field of plywood, in particular to a zero-aldehyde adhesive for plywood and a preparation method of the zero-aldehyde adhesive. The zero-aldehyde adhesive for plywood comprises the following components in parts by weight: 10-20 parts of water glass, 5-15 parts of a promoter, 20-30 parts of sodium alginate, 10-20 parts of gelatin, 3-5 parts of sodium fluosilicate, 5-10 parts of a halogen-free flame retardant and 20-30 parts of cationic water. The adhesive is good in viscosity, does not contain formaldehydes products, does not release formaldehyde, methylbenzene, xylene or the like, and can reach fireproof A2 level; and poisonous gas or smoke is not discharged.

Description

technical field [0001] The invention relates to the technical field of plywood, in particular to a zero-aldehyde adhesive for plywood and a preparation method thereof. Background technique [0002] In recent years, my country's wood-based panel industry has developed rapidly. According to records, the output of plywood in my country in 2003 was 21.02 million cubic meters, and the output of blockboard was 6.17 million cubic meters. So far, it has become the world's largest wood-based panel manufacturing and exporting country. The production of wood-based panels inevitably involves the application of adhesives. Nowadays, the main components of adhesives are urea-formaldehyde glue (UF), phenolic glue (PF) and urea-melamine-formaldehyde resin (UMF). According to the wood-based panel industry adhesive dominance of the agent. For example, the Chinese invention patent with application number CN201710317130.1 discloses a special adhesive for wood plywood, which is mainly made of t...
