Abstract
The invention discloses a method for making composite door sheets, and relates to the technical field of building material machining. The method comprises the steps that the foam layer of an old foam mattress is bonded between two base material layers with glue so that a composite man-made plate can be formed, core plates are formed by splicing finger joint battens in a bonded mode, the composite man-made plates are fixed to the upper surfaces and the lower surfaces of two or more core plates in the same direction in a bonded mode, a door sheet body is formed through cold pressing, wood veneers are bonded to the upper surface and the lower surface of the door sheet body, and a door sheet can be formed through pressure curing. Compared with the prior art, with the method, the current situation of the lack of high-quality timber is alleviated, old foam mattresses dumped by people can be recycled, the requirements for energy saving and environment protection are met, in addition, the door sheet has the external characteristics of raw wood doors, and is very competitive because of the low price, and because the composite man-made plates can be made just through overlap and cold pressing, the production technology is simple and high in efficiency; the door sheet has the good sound insulation effect, and is high in strength and applicable to the doors of boxes in entertainment venues.
Description
Technical field
The present invention relates to constructional materials processing technique field, especially a kind of preparation method of compound door plant.
Background technology
Along with the develop rapidly of China's economic construction and improving constantly of living standards of the people, add the fast development of building trade and furniture industry, the demand of timber is increased substantially, therefore, the felling quantity of log is increasing, in order to keep ecological balance, country advocates will greatly develop Novel environment-friendlymaterial material, therefore, the development of industry of artificial boards effectively alleviates the consumption of China's timber, is the important channel of saving timber.
In furniture industry, along with the requirement of people's opposite house is more and more higher, both require Convenient environmental-protective attractive in appearance, needed again protection against the tide, sound insulation good, also need good rigidly; But along with the increase of demand and the minimizing day by day of the forest reserves, the particularly scarcity of precious assortment, Solid Door disparities between supply and demand become increasingly conspicuous, also become more and more expensive, so people have developed the preparation method of wood composite door-plate, the preparation method structure of these wood composite door-plates is varied, different, generally it comprises the panel of skeleton and centre, and panel is generally wooden skin, and simple wooden skin sound insulation, protection against the tide and rigidity are good all not; Especially in public place of entertainment, musical sound, K song, confused noise, the door all needed carrys out barrier.
The main material of foam pad mattress is foam, foam pad mattress can meet the curve of health, while providing support, do not lose softness and elasticity, the action of health can be cushioned, even if also there is no sound time a people stands up, therefore simultaneously, foam pad mattress obtains the favor of wide customer and likes, the people buying foam pad mattress also gets more and more.Froth bed in foam pad mattress mainly polyurethane foam, polyurethane foam has ultralow temperature pyroconductivity, weather-proof insulation; High efficiency insulation, sound insulation, waterproof and dampproof feature; But people have the custom of abandoning the old for the new, see increasing new mattress out, even if the old mattress used is not bad, also will abandons and renew mattress, or owing to removing new family, institute's mattress of haveing been friends in the past all changes, so, a lot of not bad mattress is dropped, and taken away landfill or burning, waste very much.
Summary of the invention
The invention provides a kind of preparation method of compound door plant, it not only can solve and recycle unmanageable old foam pad mattress, soundproof effect is good and preparation method is simple.
In order to solve the problem, the technical solution adopted in the present invention is: comprise the steps:
A, by reclaim old foam pad mattress process, in old foam pad mattress, take out froth bed; Take out two blocks of basal plates, apply glue in any surface of substrate layer respectively, spread described froth bed in the face of the described substrate layer scribbling glue, then by scribble glue another described in the face of substrate layer be pressed on described froth bed, superimposed good; Superimposed good composite plate sent in cold press, sizing of colding pressing, obtains composite artificial board;
B, respectively with fiber orientation identical two or more finger lath splicing be bonded into central layer;
C, spelling door-plate: upper and lower surface composite artificial board glue being fixed in central layer, finally cold pressing and be pressed into door-plate;
D, paste wooden skin: be coated with adhesive respectively in the upper and lower surface of door-plate, be that the wooden skin of 0.5 millimeter covers on glue-coated door-plate by the thickness cut out, at least identical with door-plate area cushion is covered in wooden skin upper end, again door-plate is placed on pressurization between two flat boards be arranged in parallel, solidification, pressure is 65MPa, and pressing time is 45 minutes;
E, arrangement: numerical control machine essence is cut, hand abrasive band is rebuild and is obtained this door-plate.
In technique scheme, scheme can also be more specifically: the glue described in step A is by phenolic resins or Lauxite; Described substrate layer is three-ply board or five-ply board.
Further: temperature of colding pressing described in step A is 10 DEG C-20 DEG C, the time of colding pressing is 10min-15min, pressure is 3Mp-8Mp.
Owing to adopting technique scheme, the present invention compared with prior art, has following beneficial effect:
1, with the door-plate that this method is made, both the present situation that existing high-quality timber is in short supply had been alleviated, the reluctant old foam pad mattress that people abandon can be recycled again, reach the requirement of energy-saving and environmental protection, there is again the external feature of log door simultaneously, cheap price and make product have competitiveness, and because be only by superimposed, cold pressing and just can produce composite artificial board, production technology is simple, and efficiency is high.
2, owing to having one deck polyurethane foam in old foam pad mattress, polyurethane foam has ultralow temperature pyroconductivity, weather-proof insulation, high efficiency insulation, sound insulation, waterproof and dampproof feature, after making composite gate, the preparation method of compound door plant has such feature equally, and used for many years due to people, the taste that originally polyurethane is very heavy completely eliminates, reach the requirement of environmental protection.
