Embodiment 1

[0022] A method for microwave fast curing of wood-based panel core layer adhesive, the method comprising:

[0023] S1: Prepare wood-based panel core 1, wood-based panel core 2, wood-based panel core 3 and wood-based panel core 4, clean both sides of wood-based panel core 1, wood-based panel core 2, wood-based panel core 3 and wood-based panel core 14, and The artificial board core one is placed on the processing table, the surface of the artificial board core one is coated with adhesive, and the artificial board core two is placed on the adhesive of the artificial board core one;

[0024] S2: Use the cylinder to drive the plywood to move. The plywood squeezes the wood-based panel core 1 and the wood-based panel core 2. The adhesive between the wood-based panel core 1 and the wood-based panel core 2 is fully bonded. The first wood-based panel core and the second wood-based panel core are sent into a microwave oven for curing, and after curing, the first artificial panel core an...

Abstract

The invention belongs to the field of artificial board core preparation, particularly relates to a method for rapidly curing an artificial board core layer adhesive through microwaves. The problems that an adhesive cannot be rapidly fixed, the processing period is long and the processing efficiency is low when an existing artificial board core is prepared are solved. According to the scheme, the method includes the steps that S1, an artificial board core I, an artificial board core II, an artificial board core III and an artificial board core IV are prepared, the two faces of the artificial board core I, the artificial board core II, the artificial board core III and the artificial board core IV are cleaned up, the artificial board core I is placed on a processing table, the surface of theartificial board core I is applied with the adhesive, and the artificial board core II is placed on the adhesive of the artificial board core I; and S2, an air cylinder is used for driving a pressingplate to move, and the pressing plate presses the artificial board core I and the artificial board core II. When the artificial board cores are prepared, the adhesive can be rapidly fixed, the processing period is short, and the processing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of artificial board core preparation, in particular to a method for microwave rapid curing of an adhesive for the core layer of an artificial board. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives. It mainly includes three categories of products: plywood, particleboard and fiberboard. There are hundreds of extended products and deep-processed products. According to different raw materials, wood-based panels can be divided into fiberboard, particleboard and plywood. The core of wood-based panels needs to be bonded with adhesives. Starch adhesive has good fluidity and is suitable for the sizing process in the production of wood-based panels. At the same time, due to the cross-linking reaction between starch ...
