Abstract
The invention discloses processing method of a kind of bamboo wood facing surface layer and products thereof.This processing method comprises the steps:, in the glue that bamboo skin impregnated in melmac, to bake and bank up with earth dry, and laminated hot pressing obtains bamboo wood facing；Wherein, described glue also comprises PMMA and/or PVDF；The temperature of described hot pressing is 100 160 DEG C, and the unit pressure of described hot pressing is 15 60KG/cm2, the time of described hot pressing is 15 100min.The processing method high-efficiency environment friendly of the present invention, technique are simple, the physical properties index of prepared bamboo wood facing surface layer is more excellent, effectively eliminate occur after existing product comes into operation blackout, go mouldy, be layered puzzlements caused to beautiful decoration and later maintenance such as flaking, become mildewed.
Description
Technical field
The present invention relates to processing method of a kind of bamboo wood facing surface layer and products thereof.
Background technology
Bamboo is the resource that a kind of reproducibility is the strongest, and growth cycle is short, in addition aboundresources, carbon dioxide neutrality row
Put, thus be used as a kind of novel natural material through being processed into bamboo skin facing.
Existing technology is typically the surface layer to bamboo wood facing, carries out paint process, to reach attractive in appearance, waterproof, Anti-moth-eating.
Common are the ways such as five two sides, the end, seven two sides, the end, through the bamboo skin decorations that sanding japanning guarantee is made the most repeatedly
Face smooth surface is smooth without bubbling.Concrete steps are as follows: bamboo wood facing element plate sanding, sorting, and travel fatigue is removed, hot air drying
Dry, it is coated with putty, UV solidifies, sanding, priming paint, and UV solidifies, sanding, priming paint, and UV solidifies, sanding, priming paint, and UV solidifies, sanding, the end
Paint, UV solidifies, sanding, priming paint, and UV solidifies, sanding, finish paint, and UV solidifies, finish paint, and UV solidifies, checks to obtain goods.
In the processing method of prior art, complex process, need to be polished for a plurality of times japanning, dust and organic wave in process
Send out part high, not environmentally；Through the surface layer of the bamboo wood facing that above-mentioned paint processes, also exist in actual use blackout, go mouldy,
Layering is flaked, the shortcoming such as become mildewed, to bamboo wood facing promote the use of and later stage cleaning brings greatly puzzlement.
Summary of the invention
The technical problem to be solved is to overcome in prior art many in bamboo wood facing surface layer process
Secondary polishing japanning, technique are considerably complicated, dust and organic volatile part is high, not environmentally, and bamboo wood facing is in actual use
There is blackout, go mouldy, be layered the defects such as shortcoming such as flaking, become mildewed, it is provided that the processing method of a kind of bamboo wood facing surface layer and
Its product.The processing method high-efficiency environment friendly of the present invention, technique are simple, and the physical properties index of bamboo wood facing surface layer is more excellent
Different, effectively eliminate occur after existing product comes into operation blackout, go mouldy, be layered flake, become mildewed etc. to beautiful decoration and
The caused puzzlement of later maintenance.
The present invention solves the problems referred to above by the following technical programs.
The processing method that the invention provides a kind of bamboo wood facing surface layer, it comprises the steps:
Bamboo skin impregnated in the glue of melmac, bakes and banks up with earth dry, and laminated hot pressing obtains bamboo wood facing；Wherein, institute
The glue stated also comprises PMMA and/or PVDF；The temperature of described hot pressing is 100-160 DEG C, the unit pressure of described hot pressing
Power is 15-60KG/cm2, the time of described hot pressing is 15-100min.
Wherein, described bamboo skin is preferably comprised true qualities concora crush bamboo skin, carbonization concora crush bamboo skin, true qualities side pressure bamboo skin and carbonization
One or more in side pressure bamboo skin.The thickness of described bamboo skin is preferably 0.25-20mm.The breadth of described bamboo skin is this
Routine, generally 1250*2500mm, 1250*3100mm or 1220*3050mm in field.
Wherein, described glue preferably contains the melamine of 40-80%, PMMA's and 0-20% of 10-40%
PVDF；Above-mentioned percentage is all mass percent.
Wherein, described glue is preferably made up of following substances: the melamine of 40-80%, the PMMA of 10-40%
PVDF with 0-20%；Above-mentioned percentage is all mass percent.
Wherein, described bake and bank up with earth dry method and condition is that this area is conventional, preferably in the bamboo skin after dipping
Resin content is 20-50%, and the volatile content of resin is 5-15%；Above-mentioned percentage is all mass percent.
Wherein, the number of plies of described lamination hot pressing is preferably 1-40.
Present invention also offers a kind of bamboo wood Decorative surface work prepared by above-mentioned processing method.
On the basis of meeting common sense in the field, above-mentioned each optimum condition, can be combined, obtain each preferable reality of the present invention
Example.
Agents useful for same of the present invention and raw material are the most commercially.
The most progressive effect of the present invention is:
1, the processing method high-efficiency environment friendly of bamboo wood facing aspect of the present invention, technique are simple；
The free formaldehyde release of the bamboo wood facing that 2, prepared by the present invention, reaches country's E1 grade standard；
3, the bamboo wood facing moistureproof and mildewproof that prepared by the present invention becomes, and does not falls off, and not stratified flakes, and does not becomes mildewed, and surface strength is high.
Detailed description of the invention
Further illustrate the present invention below by the mode of embodiment, but the most therefore limit the present invention to described reality
