Environment-friendly bamboo wood adhesive and bamboo wood dip-coating method

Abstract

The invention discloses an environment-friendly bamboo wood adhesive and a bamboo wood dip-coating method. The environment-friendly bamboo wood adhesive comprises water, vegetable protein, a modifier, a cross-linking agent, a curing agent, a filler and an additive; the bamboo wood adhesive is prepared from the following components in parts by mass: 100 parts of water, 20-40 parts of vegetable protein, 0.1-5 parts of a modifier, 20-40 parts of a cross-linking agent, 2-20 parts of a curing agent, 1-5 parts of a filler and 3 parts of an additive; and according to the environment-friendly bamboo wood adhesive disclosed by the invention, the actions of picking, soaking, spreading and draining, splicing, glue scraping and the like are automatically completed on a wood bamboo board through a bamboo wood dip-coating device, so that the four side walls of the wood bamboo board can be uniformly and fully coated with the adhesive after the bottom surface of the wood bamboo board is soaked with the adhesive, through the glue scraping action, and the glue adhering to the edges, close to the four side walls of the wood bamboo board, of the top face of the wood bamboo board is automatically removed through the processes of blocking, shoveling, wiping and the like, so that the automation integration degree is achieved, and the production quality standard is unified.

Description

technical field [0001] The invention relates to the technical field of bamboo and wood processing structures, in particular to an environment-friendly bamboo and wood adhesive and a bamboo and wood dipping method. Background technique [0002] With the depletion of wood resources, people are increasingly using wood-based panel furniture instead of solid wood furniture, so that the amount of adhesives is also increasing. The research and application of adhesives is a time-honored science. As early as prehistoric times, human beings have begun to use natural adhesives such as blood glue, bone glue, and plant extracts. However, due to its disadvantages such as poor water resistance, low solid content, low bonding strength, easy mildew, and short storage period, it was gradually replaced by the developed "trialdehyde glue". At present, "trialdehyde glue" is the main adhesive for wood-based panels, but "trialdehyde glue" mainly uses formaldehyde, urea, melamine, phenol, etc. as ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems in the prior art, the purpose of the present invention is to provide an environment-friendly bamboo wood adhesive and a bamboo wood dipping method to solve the existing problem that some special bamboo wood boards with larger surface areas need to be bonded, which is often a problem. The glue on the surface of the bamboo board is soaked and evenly applied to make the glue on the surface of the bamboo board evenly adhered to it. Therefore, the adhesive disclosed in the above patent is applied to the surface of the wooden material by roller coating or spraying, which will obviously cause uneven application of the adhesive. , the technical problem that the bonding strength of the adhesive cannot be brought into full play
