Abstract
The method for making impregnated artificial board features that ordinary pressure process or pressurizing process is used to impregnate ordinary artificial board with more kinds of oily solvent by adding simple impregnation apparatus to production line of ordinary artificial board. Obtained board has stable sizes.
Description
The invention belongs to a kind of wood-based plate and manufacture method thereof, particularly in a kind of modified artificial plate and impregnating method thereof that impregnates oil-based solvent.
Existing various wood-based plate, be mostly to apply adhesive with wood shavings or particle after mix, mat formation, hot-pressing processing forms the also adding a certain amount of anticorrisive agent, fireproof agent or the waterproofing agent that have.But find that in actual use this wood-based plate is behind certain hour, particularly Lauxite particieboard and melmac particieboard be in humidity, or do wet bigger grade for the place that changes, and is difficult to keep stablizing of its original size, has a strong impact on its result of use.
The objective of the invention is to overcome problems of the prior art, propose a kind of impregnation of artificial board and impregnating method thereof, it can guarantee size stable of its sheet material enduringly.
Impregnation of artificial board of the present invention, it is to impregnate with non-pressure process or pressurization multiple oil-based solvent is arranged in common wood-based plate, is divided into the certain thickness part of sheet material of impregnating entirely or impregnate of soaking into whole sheet materials and impregnates according to the degree of depth of impregnating of finish.Described wood-based plate comprises the timber medium density fibre board (MDF), wooden plane card, the straw particieboard of crop stalk medium density fibre board (MDF), crops, bamboo wood medium density fibre board (MDF) or bamboo shaving board.Described oil-based solvent comprises coal tar or oil one heavy oil and the fraction between 200 ℃-400 ℃ thereof, carbolineum, castor oil, linseed oil, rapeseed oil, peanut oil and their mixed solvent.
A kind of method of impregnation of artificial board the steps include:
(1) in immersion can, adds oil-based solvent or its mixed solvent;
(2) oil-based solvent or its mixed solvent are heated to 10 ℃-180 ℃;
(3) wood-based plate is put into immersion can, impregnate with normal pressure or pressurization, the time of impregnating is 10-120 minute;
(4) discharging impregnation of artificial board.
Gauge pressure is 0.1-0.4MPa in the immersion can of described pressurization impregnation of artificial board, vacuumizes after the release, and vacuum is the 250-700mm mercury column.
The major advantage of impregnation of artificial board of the present invention is:
1, can improve the performance of common wood-based plate significantly, particularly make its size long-term stability constant, and through the DIN68763V100 standard testing, the swollen rate of rising of its water sucting thickness is not more than 12%;
2, its scope of application of having enlarged wood-based plate can be done concrete blinding directly in outdoor application, railway is heightened plate, antifreeze backing plate etc.;
3, need not change the process equipment of existing wood-based plate, as long as increase the easy equipment that impregnates;
4, according to different purposes, the degree of depth of impregnating can be controlled.
In order to further specify the structure of impregnation of artificial board of the present invention, will consult accompanying drawing and specifically described with embodiment, its accompanying drawing has:
Fig. 1 impregnates the plate perspective view for the part in this impregnation of artificial board;
Fig. 2 is for impregnating the plate perspective view entirely in this impregnation of artificial board.
In Fig. 1,2: 1 is impregnation of artificial board, and 2 for not impregnating layer, and 3 for impregnating layer.
Embodiment:
Impregnate hemp plate with what non-pressure process was made, as shown in Figure 1, earlier the heavy oil of weight 60% and 40% carbolineum mixed solvent are put into immersion can, heating, temperature is raised to 100 ℃, puts into the hemp plate that thickness of slab is 8mm, impregnated 60 minutes, discharging promptly gets treated impregnation of artificial board.
