Abstract

The invention discloses a vegetable oil-based adhesive, a composite plywood and a method for manufacturing the composite plywood from the vegetable oil-based adhesive. The vegetable oil-based adhesive comprises a vegetable oil-based resin, a reactive resin, a curing agent, a catalyst and additives and does not contain the formaldehyde. The composite plywood manufactured from the vegetable oil-based adhesive has high strength and good water resistance, does not contain benzene, toluene, xylene and other harmful substances and can not cause pollution to the environment. The waste petrochemical resin can be recycled, the resources can be saved, the economic cost can be saved, the use amount of the environmentally-friendly renewable materials can be increased, and the harm of the traditional composite plywood comprising the formaldehyde glue to the environment can be avoided. The composite plywood can be used as the furniture board and the floor and can be used for architectural decoration and internal decoration of motor vehicles.

Description

technical field [0001] The invention relates to an adhesive, a manufacturing method of an artificial board and an artificial board, in particular to a vegetable oil-based adhesive, a method for manufacturing an artificial board by using the vegetable oil-based adhesive and a composite artificial board. Background technique [0002] Traditional wood-based panels are mainly made of wood or other non-wood plants bonded by adhesives, and then molded in a certain way, which has a wide range of uses in architectural decoration, furniture, flooring and other fields. At present, the adhesives used in the wood-based panel industry are mostly urea-formaldehyde resin, phenolic resin, and melamine-formaldehyde resin. These three types of glue use formaldehyde as a raw material, and a large amount of formaldehyde will be released during the processing and later utilization of wood-based panels, which seriously endanger people's health. At present, countries around the world have also pro...
