Embodiment Construction

[0021] Below in conjunction with accompanying drawing and case the present invention will be further described:

[0022] A kind of cold press fast gluing method that is used for wood of the present invention comprises the following basic steps: 1) wood preparation: wood is dried to certain moisture content, is generally 10%~20%, then the surface to be glued is processed into smooth level surface, or process the dried wood into a regular geometry, and the surface to be glued is flat and smooth. 2) Sizing: apply the main adhesive agent to the A side of the wood, and the auxiliary agent to the B side, see figure 1 . Or apply the adhesive main agent and auxiliary agent to the A side and B side of a group of wood to be glued respectively, see figure 2 , The application amount of the main agent is about 50 grams to 300 grams per square meter, and the application amount of the auxiliary agent is applied appropriately according to the needs of the gluing process. The main agent ma...

Abstract

The invention provides a cold-pressed rapid gluing method for wood, belongs to the technical field of wood science and is suitable for solid wood gluing, or production manufacturing of laminated wood or a laminated wood board, or laminating processing of an artificial board and the like. The method adopts a method of separately applying an adhesive main agent and an assistant; when two surfaces to be glued are not in contact, the adhesive main agent and the assistant independently exist and are very stable; after the two surfaces to be glued are in contact, the reaction speed of the main agent is sharply improved under the action of the assistant and an adhesive is rapidly cured and glued. The basic process of the cold-pressed rapid gluing method comprises the following five steps: 1, preparing wood; 2, applying the adhesive main agent and the assistant; 3, loading boards; 4, carrying out cold-pressed gluing; and 5, unloading the boards. The cold-pressed rapid gluing method for wood has the advantages of high production efficiency, high wood utilization rate, energy conservation, simple process equipment and high product quality and is suitable for rapid gluing of wood with high moisture content and a large size.

Description

1. Technical field [0001] The invention relates to a cold-press fast gluing method for wood, which belongs to the field of wood science and technology, and is mainly used for cold-press fast gluing of wood, and is suitable for the production and manufacture of wood-based panels such as solid wood gluing or integrated timber or blockboard . 2. Background technology [0002] In the wood industry production, the gluing methods of wood mainly include hot-press gluing method and cold-press gluing method. The hot pressing method is the process of putting the unit to be glued after sizing into the pre-heated or unheated platen for heating and pressing. The main function of heat is to accelerate the curing speed of the adhesive, shorten the hot pressing time, and improve production efficiency. The role of pressure is mainly to increase the contact area between the glued units and to further spread the adhesive, increasing the glued area and glued effect. The cold pressing method i...
