Problems solved by technology
However, the problem with the above operation method is that the price of polyethylene film paper is more expensive than that required by the general commercially available WBPPlywood (waterproof plywood, usually cooked at 100 degrees Celsius) or MRPlywood (moisture-proof plywood, usually cooked at 60 degrees Celsius) The cost of adhesive materials is several times more expensive; the higher production cost limits the production volume
However, the problem with this method is that ordinary gelled synthetic products undergo high-temperature carbonization above 215°C, which often makes the structure difficult to withstand high temperatures for a long time, and the glue will be damaged.

Embodiment Construction
[0015] The methods, features and embodiments of the present invention are described below with reference to the accompanying drawings, so as to have a further understanding of the present invention. Steps of the present invention:
[0016] 1. Take a plurality of wood veneers, and the average thickness of each wood veneer is not less than 0.15mm; the above-mentioned veneers are made of various logs that are rotary cut or flat cut from 0.15mm to 6mm or thicker.
[0017] 2. After drying, the moisture content of each wood veneer is below 8%;
[0018] 3. The two adjacent layers of wood veneers are mutually selected from silicone glue, phenolic resin glue, urea-formaldehyde resin glue, temperature-resistant epoxy glue, polyimide glue, melamine modified glue, high temperature resistant inorganic nano One of the composite adhesives is coated and glued, and the boards are combined to form the use specifications; the glue and boards are carried out according to the current industry and...

The invention relates to a preparation method of a carbonizing plywood. The preparation method comprises the following steps of using a plurality of single wood plates; coating and laminating the two adjacent single wood plates by one of organic silicon glue, phenolic resin glue, urea resin glue, heat-resistant epoxy glue, polyimide glue, melamine modified glue and high temperature-resistant inorganic nanometer composite adhesive; combining and arranging into the use size; gluing, decompressing, and sending into a hot press. The preparation method has the advantage that the plate blank and the carbonizing plywood can be quickly, simply, easily and stably manufactured.
Description
technical field [0001] The invention relates to a preparation method of plywood, in particular to a preparation method of carbonized plywood. Background technique [0002] The wood is treated with high temperature to make it have anti-corrosion, moisture-proof, anti-bacteria (insect) and other characteristics to form carbonized wood. Carbonized wood is not easy to absorb water, and it is not easy to deform, so it is a kind of wood material that is widely used at present. In addition, carbonization technology can also make plywood (or plywood, which is laminated by thinner wood boards) modified (carbon stabilized substances), thereby improving the quality of the board. At present, there are mainly the following kinds of plywood carbonization operation methods: [0003] The first method: take the multi-layer wood veneer, and glue each layer with polyethylene film paper as the glue medium; then send the supporting plate (aluminum plate or other backing plate) for the embryo i...
