Problems solved by technology

[0003] 1. After the plywood leaves the factory, formaldehyde resin is continuously released, which is harmful to the health of consumers
[0004] 2. Formaldehyde resin is not waterproof. When encountering high temperature or water environment, the nail formed by formaldehyde resin is easy to soften, causing the plywood to be degummed, resulting in a short service life, resulting in a short service life of the building decoration part, which often needs to be redecorated. It causes inconvenience to life, and due to the elimination and replacement of plywood in the replacement process, it causes an increase in urban waste, affects environmental protection, and in the long run, also accelerates the destruction of the earth's forest resources
[0005] 3. If bad gluing is found during the production process, the entire plywood semi-finished product or finished product can only be scrapped, and it cannot be reworked and recycled, which not only wastes raw materials, but also increases waste, causing environmental problems

Embodiment Construction

[0032] As shown in Figure 2, the plywood of the present invention is made up of at least two layers of superimposed veneers 1, which is characterized in that a layer of recyclable PE or PP or PET or other waste materials is arranged between adjacent two veneers 1. A polymer film layer 2 processed from plastic, wherein the veneers 1 are glued and connected by glue nails formed by melting the polymer film layer 2 between two adjacent veneers 1 by heating and pressing in a molding machine as one.

[0033] As shown in Figure 3, the manufacture method of plywood of the present invention comprises the following steps:

[0034] (1), cutting the logs into log segments of suitable length;

[0035] (2), cutting the log section cut into a suitable length into log thin slices;

[0036] (3), cutting the log flakes into specifications and drying them;

[0037] (4), alternately arrange and laminate the dried log sheets and polymer films made of recyclable waste plastics such as PE, PP or ...

Abstract

A technology for preparing plywood includes such steps as providing at least two thin wood sheets, arranging a polymer film between adjacent two wood sheets, and hot pressing. Its advantages are not releasing formaldehyde and high adhesion.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a method for manufacturing a composite wood board. Background technique [0002] Existing composite wood boards are generally made of laminated multi-layer veneers by coating molten formaldehyde resin glue between each layer of veneer and using a forming press to harden the formaldehyde resin glue under appropriate temperature and pressure conditions. It is composed of thin wood chips connected, and its basic manufacturing process is shown in Figure 1. This kind of composite board has the following disadvantages: [0003] 1. After the plywood leaves the factory, formaldehyde resin is continuously released, which is harmful to the health of consumers. [0004] 2. Formaldehyde resin is not waterproof. When encountering high temperature or water environment, the nail formed by formaldehyde resin is easy to soften, causing the plywood to be degummed, resulting...
