Problems solved by technology

Heating and curing is a double-edged sword. Heating can speed up the curing speed. However, after the prepared glue is heated, the storage period of the glue will be greatly shortened. It is necessary to remove the unused glue from the glue pot in time.
Bamboo wood board is a new material with clear surface, pleasant aroma, bright color, elegant temperament and quality, but the shrinkage and expansion rate of bamboo wood is relatively large, so the use of non-curing agent-free puzzle glue is prone to insufficient bonding strength And the problem of cracking

Abstract

The invention relates to the technical field of plate splicing glue, and in particular, relates to a water-based single-component plate splicing adhesive for bamboo and a preparation method of the water-based single-component plate splicing adhesive. The plate splicing adhesive innovatively adopts a double-colloidal particle double-emulsion system, the acrylate copolymer emulsion A still takes vinyl acetate as a main monomer to ensure the bonding strength and the normal-temperature curing capacity of the plate splicing adhesive, and an acrylate copolymer emulsion B takes butyl acrylate as a main monomer, so that the synthesized latex is lower in viscosity and smaller in colloidal particle size. Then through mixing of the two components and a cross-linking reaction of unreacted propane trimethanol triacrylate, the interface performance brought by comprehensive infiltration performance and the strength performance brought by cohesive energy performance are improved, the bonding performance of the plate splicing adhesive is remarkably improved, and through dispersion matching of large and small colloidal particles, the compactness of a film layer is improved; therefore, the water resistance and the high and low temperature resistance of the plate splicing adhesive are improved.

Description

technical field [0001] The invention relates to the technical field of panel glue, in particular to a water-based one-component panel glue for bamboo and a preparation method thereof. Background technique [0002] With the development of the economy, people's demand for wooden furniture has gradually increased from focusing on the appearance to focusing on the material. However, solid wood cannot be directly used for furniture production, and solid wood sawn timber must be used as solid wood panels for production. Most of the glues currently used for solid wood puzzles use polyvinyl alcohol as the protective colloid, and add various additives for cross-linking modification. During the use of jigsaw glue, it is necessary to add a curing agent containing isocyanate in a certain proportion. After the curing agent is added to the jigsaw glue, the pot life is greatly shortened, and it needs to be adjusted and used immediately. In order to improve efficiency, some manufacturers ...
