Abstract
The invention discloses a composite artificial board produced by using a scraped car roof and a preparation method thereof, and relates to the technical field of the artificial board. The composite artificial board comprises at least two layers of substrate layers; a sound-insulating and heat-insulating layer is installed between the substrate layers; the sound-insulating and heat-insulating layer is the scraped car roof board layer; and a glue layer is installed between the substrate layer and the sound-insulating and heat-insulating layer. The preparation method comprises the steps: coating the glue on one or two faces of the wood board, overlapping with the scraped car roof, forming by pressing, and obtaining the composite artificial board in the certain standard. The strength of the artificial board manufactured by the preparation method is similar to the strength of the common artificial board in the market, and because the car roof has the polyurethane foam with good sound-insulating and heat-insulating performance, the sound-insulating and heat-insulating effect is better than that of general artificial board, the density is smaller than that of the normal artificial board, and more important is that the difficultly-processed scraped car roof in the auto industry can be recycled, the process is simple, and the production efficiency is high.
Description
Technical field
The present invention relates to man-made board technology field, especially a kind of composite artificial board utilizing abandoned car top to produce and preparation method thereof.
Background technology
Along with growth and economic the developing rapidly of world population, automobile industry is also along with fast development.In Jan-Sept, 2013, the automobile that China produces reaches 1,593 ten thousand, and increase by 12.78% on a year-on-year basis, sales volume reaches 1,588 ten thousand, increases by 12.7%. on a year-on-year basis but meanwhile, along with the raising of auto output, in car, plastic refuse also gets more and more.And the main method that current China processes these waste materials is exactly traditional landfill and burning, this not only causes serious pollution to the living environment of the mankind, waste valuable resource, seriously run counter to current social is advocated green, environmental protection, energy-conservation sustainable development economy pattern.Therefore, how economical, rationally, effectively process the problem that increasing automobile waste plastics have become the research of one, the world today.
China is one of country of the few material of scarce woods, wood supply breach relies on import in a large number, and along with the fast development of building trade and furniture industry in recent years, domestic Wood demand sharp increase, therefore the development of industry of artificial boards effectively alleviates the consumption of China's timber, is the important channel of saving timber.
In automobile calash manufacturing process, can produce underproof top, the composite board that these tops are made up of glass, foam, non-woven fabrics, glue, owing to having some surperficial folding lines, dirty, aberration, the shaping reason such as not in place scraps, to take away landfill or burning, waste very much.
Summary of the invention
An object of the present invention is to provide a kind of composite artificial board utilizing abandoned car top to produce, and it not only can solve and recycle unmanageable abandoned car ceiling, and its sound-insulating and heat-insulating is effective.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: comprise at least two-layer substrate layer, be provided with sound-insulating and heat-insulating layer between each substrate layer; Described sound-insulating and heat-insulating layer is abandoned car ceiling flaggy, is provided with glue layer between described substrate layer and described sound-insulating and heat-insulating layer.
In technique scheme, scheme can also be more specifically: described glue layer is made up of the one in phenolic resins, Lauxite, methyl diphenylene diisocyanate or plant oil based glue.
Further: described substrate layer is three-ply board or glued board.
It is simple that second object of the present invention is to provide a kind of production technology, and the preparation method of the composite artificial board that efficiency is high, comprises the steps:
A, to apply glue in any surface of substrate layer respectively;
B, spread abandoned car ceiling plate in the face of the substrate layer scribbling glue, then be pressed on abandoned car ceiling plate in the face of another substrate layer scribbling glue, the rest may be inferred, superimposed good;
C, superimposed good composite plate is sent in hot press, hot-forming, obtain shaping composite plate;
D, sent in cold press by the molded composite board of step C gained, sizing of colding pressing, obtains composite artificial board.
In technique scheme, scheme can also be more specifically:
In the step A, the consumption of described glue is 1.2-1.3kg, and the specification of described substrate layer is 1220*2440mm;
In the step C, described hot pressing temperature is 140 DEG C-170 DEG C, and hot pressing time is 5min-8min, pressure is 10Mp-15Mp;
In the step D, temperature of colding pressing described in is 10 DEG C-20 DEG C, the time of colding pressing is 5min-8min, pressure is 3Mp-8Mp; The thickness of described composite artificial board is 5mm-15mm.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, owing to being adopt abandoned car ceiling as sound-insulating and heat-insulating layer, therefore, the reluctant abandoned car ceiling in automobile industry can be recycled, and because be only by superimposed, hot pressing, cold pressing and just can produce composite artificial board, production technology is simple, and efficiency is high.
2, owing to there being one deck PU foam in automobile ceiling, after making composite board, the common wood-based plate of density ratio is little, and foam has good sound-absorbing endothermic effect, and the sound-insulating and heat-insulating effect of the composite regenerated plate made is better than common wood-based plate.
