Abstract

The invention discloses a bi-component starch-based adhesive for a wood and belongs to the technical field of deep processing of woods. The bi-component starch-based adhesive for the wood is formed byseparately packaging a component A and a component B, wherein the component A is prepared by adding 40-50 parts of starch paste, 20-30 parts of activated chitosan, 10-20 parts of humic acid, 10-20 parts of modified additive and 10-20 parts of nanometer silica into a 3# beaker according to part weight, and carrying out stirring and mixing at the rotating speed of 300-500r/min for 40-60min; and thecomponent B is prepared by adding 10-20 parts of isocyanate, 8-10 parts of konjac glucomannan, 8-10 parts of silane coupling agent and 3-5 parts of crosslinking agent into a 4# beaker according to part weight, and carrying out stirring and mixing at the rotating speed of 300-500r/min for 40-60min. By using the bi-component starch-based adhesive for the wood, provided by the invention, a system isenabled to have excellent water resistance and mechanical properties.

Description

technical field [0001] The invention discloses a two-component starch-based adhesive for wood, which belongs to the technical field of wood deep processing. Background technique [0002] Adhesives play a pivotal role in the full utilization of wood resources, such as traditional urea-formaldehyde resins, phenolic resins, melamine-formaldehyde resins, etc. Among the existing woodworking adhesive systems, the fatal defect of formaldehyde-based adhesives is that during the production and use of bonded wood products, harmful gases such as free formaldehyde will inevitably be released, which will endanger producers and consumers. The health of the body; water-based adhesives use water as the dispersion medium, are odorless, non-polluting, and are environmentally friendly adhesives. Although water-based polymeric isocyanate adhesive (API) does not release free formaldehyde, its high viscosity, short pot life and high cost limit its wide application in wood gluing. However, with ...
