Problems solved by technology

[0002] In the decoration or wooden door industry, multi-layer boards are widely used. Almost all the current multi-layer boards have a common quality defect. The products are easy to "deform" and "unglue", and the production cost is relatively high; and the impact on the environment is relatively large.

Embodiment Construction

[0020] The technical solutions of the present invention will be described in detail below through specific examples.

[0021] Taking the 9+2 layer board as an example to illustrate, the detailed process steps are:

[0022] a. First adjust the glue, and then paste the plates into nine-layer plywood with the adjusted glue, the amount of glue is 0.9-1.1 kg / sheet; the composition of the glue is the following components by weight, urea-formaldehyde resin 60 parts of binder (urea-formaldehyde glue), 35 parts of flour, 5 parts of curing agent, and the curing agent is ammonium chloride.

[0023] b. Cold press, repair, hot press, sanding, and thickness setting of the bonded nine-layer plywood. The cold pressing pressure is 12mpa, and the time is 120min; the hot pressing pressure is 14mpa, the temperature is 110°C, and the time is 23min; Optical thickness is 13.2mm.

[0024] c. After setting the thickness, continue to paste two layers of plates, and then go through cold pressing, repa...

Abstract

The invention belongs to the technical field of wooden multi-layer boards which are used for decoration, and particularly relates to a method for producing a multi-layer board. The multi-layer board also can be applied to production of wooden doors and cabinet furniture. The method specifically comprises the steps of firstly mixing glue; then sticking sheet materials into multiple layers of plywood by using the mixed glue; subjecting the stuck multiple layers of plywood to cold pressing, repairing , hot pressing, sanding and thicknessing, sticking two layers of sheet materials into the multiple layers of plywood continuously, and then performing cold pressing, repairing, hot pressing, putty mending, sanding and edge trimming; producing the multi-layer board as required by the similar steps; and finally completing surface overlaying, hot pressing, polishing, edge trimming, packing and storage to obtain the product. The multi-layer board prepared by the method is high in quality and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of wooden multilayer boards for decoration, and specifically relates to a method for manufacturing multilayer boards. The multilayer boards can also be applied to the production of wooden doors and cabinet furniture. Background technique [0002] In the decoration or wooden door industry, multi-layer boards are widely used. Almost all the current multi-layer boards have a common quality defect. The products are easy to "deform" and "unglue", and the production cost is relatively high; and the impact on the environment is relatively large. . Through further research on domestic and foreign sheet metal processing enterprises and products, it is found that with the improvement of people's living standards, the demand for multi-layer boards has changed from low-end products to mid-to-high-end and environmentally friendly products. Therefore, an economic , Practical new type, high-grade plate. Contents of the ...
