Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an anti-corrosion and moisture-proof adhesive for bamboo and wood processing. Background technique [0002] A new type of adhesive based on synthetic polymers—synthetic polymer adhesives. The most widely used and most representative formaldehyde-based adhesives include urea-formaldehyde resin adhesives, phenolic resin adhesives, and melamine. Among them, urea-formaldehyde resin is used in the largest amount, accounting for about 80% of the amount of formaldehyde-based adhesives and 60% of the total consumption of bamboo and wood adhesives. This type of adhesive has developed rapidly due to its small molecular weight, good wettability, and high bonding strength, and soon replaced natural adhesives and occupied the wood adhesive market. Compared with phenolic resin and melamine resin, the water resistance of urea-formaldehyde resin is poor, mainly because after curing, urea-form...
