Embodiment Construction

[0023] The manufacturing method of the multi-layer solid wood composite board used in the multi-layer solid wood composite door is as follows:

[0024] (1) Log rotary cutting, cut into 2000×1000×4mm and 1000×2000×4mm planks;

[0025] (2) The plank is dried by hot pressing, the drying temperature is 200°C, the pressure is 1 kg / cm2, and the water content of the plank after drying is 8-13%;

[0026] (3) Repair the defect of the plank;

[0027] (4) Coat both sides of the board with urea-formaldehyde glue;

[0028] (5) Carry out cold pressing, with the plank after gluing, wood grain is superimposed horizontally and vertically to form 5 layers, the pressure is 9 kg / cm2, and the time is 1 hour;

[0029] (6) Carry out hot pressing, pressure 10 kilograms / square centimeter, hot pressing temperature 200 ℃, hot pressing time is 26 minutes;

[0030] (7) Surface sanding, polishing, and sawing edge forming.

[0031] The manufacturing method of the multi-layer solid wood composite door is...

Abstract

The invention relates to a multilayer solid wood composite door which is characterized in that a door body is of a single-board structure processed by clipping, carving, polishing and oiling multilayer solid wood composite boards. The method for manufacturing the multilayer solid wood composite board is as follows: (1) rotationally cutting logs into wood boards of 3 to 6 mm specification; (2) carrying out heat pressing and drying processes to the wood boards; (3) coating glue on two sides of the wood boards; (4) carrying out cold pressing; (5) carrying out heat pressing; and (6) sanding and polishing surfaces and carrying out final trimming and shaping. The invention has the beneficial effects of 1) obtaining the multilayer solid wood composite board with excellent physical mechanics property and machining property as the multilayer solid wood composite board is formed by hot-pressing multilayer rotationally-cut boards in a crisscross pattern; 2) obtaining integrated structure so as to restrict the sinking of door sides to the maximum extent; 3) gluing 5 to 11 layers of boards of 3 to 6 mm specification together so as to reduce the usage of glue and overcome the contamination caused by excessive formaldehyde; and 4) adopting the rotary-cutting technique to cut logs so as to enhance the utilization rate of wood.

Description

technical field [0001] The invention relates to the field of decorative doors, in particular to a multi-layer solid wood composite door. Background technique [0002] With the improvement of people's living standards and the deepening of the concept of pursuing quality of life, people's requirements for home decoration are getting higher and higher, and various new living room doors have emerged, such as solid wood doors, solid wood composite doors, paint-free doors, wood-plastic doors Doors, etc., but these door types all have some insurmountable defects because of their own materials or structures. [0003] For example, due to different tree species, different places of origin, and different site conditions, the properties of solid wood doors vary greatly. National standards generally only require the moisture content of the factory, but cannot establish quantitative standards for cracking and deformation during use. Also have the low timber utilization rate (generally on...
