Description
Technical field
The present invention relates to melamine impregnated paper matt facing technology fields, it is more particularly related to 0 ° a kind of
Matt impregnated paper milky coating process.
Background technique
In order to pursue green and environmental protection, currently, people more like timber and furniture and indoor decoration exempt from paint,
It is decorated with matte decoration paper.The finishing material of interior decoration 0 ° of matt of prevalence, makes to be radiated on furniture and ornament materials
Light is more in diffusing reflection or scattering.To keep the vision perception of people more comfortable, light is softer.
Other ornament materials currently used in the market, general 27-32 ° of surface brightness, vision glazed thread is brighter, at certain
A angle glazed thread is dazzling.And the 0 ° of matt melamine dipping decorative paper just to have come into vogue on the market, actual measurement brightness are
5.6-6.1 degree left and right, adaptive capacity market demands.
0 ° of matt milky impregnated paper, the brightness of steel plate is very low when veneer, and surfacing process parameter is different from conventional impregnation paper；
Pressure and time are constant, and temperature is excessively high or hot pressing time is longer, will lead to product surface and the defects of bubble occur, processing
When be easy to appear chipping, be waste product；
In the case where pressure above, temperature-resistant, hot pressing time is short, and product surface easily occurs water stain, and plate face hardness is low at this time,
The defects of being easy to appear scratch is also easy to appear scratch even if slightly drawing product surface；When veneer temperature is lower than technological parameter
When, product surface also can not form hard formation, cause that product surface is scratch-resistant, not scratch-resistant, scratch easily occurs, according to product quality
Test stone, this product are also waste product；
In addition, cooling rate is too fast to make plate generate drying shrinkage stress, in sky although plate back patch balance paper eliminates stress
When air humidity degree changes greatly, stress release is too fast, and plate can also generate bending or deformation.
Therefore, various machined parameters are unstable in 0 ° of milky white impregnated paper its surfacing process in the prior art can all cause to overlay
The increase of difficulty and the reduction of yield rate.
Therefore, need it is a kind of should 0 ° of matt impregnated paper soft light, guarantee makes light in diffusing reflection or scattering, again
There is 0 ° of matt impregnated paper milky of the stable chemical properties such as acidproof, alkaline-resisting, the resistance to fire-retardant, scratch-resistant of melamine product to paste
Face method.
Summary of the invention
In order to overcome the drawbacks described above of the prior art, the embodiment of the present invention provides a kind of 0 ° of matt impregnated paper milky patch
Face method is 5.5 ° -6 ° of veneer steel plate by preparing brightness, after cleaning out as in hot press upper hot pressboard and lower heat
Pressing plate；Then 0 ° of melamine-impregnated finishing paper is mated formation in substrate surface, carries out hot pressing, different substrate thickness is arranged different
Hot pressing time, and guarantee veneer pressure be 13MPA, hot pressing temperature be 190-200 DEG C；Then to cleared of debris side after hot pressing
Angle；Finally obtained finished product is cooled down and eliminates stress, veneer is completed, the fill light of the existing 0 ° of matt impregnated paper of obtained finished product
Line, guarantee make light in diffusing reflection or scattering, have acidproof, alkaline-resisting, resistance to fire-retardant, scratch-resistant of melamine product etc. to stablize again
Chemical property.
To achieve the above object, the invention provides the following technical scheme: a kind of 0 ° of matt impregnated paper milky coating process,
Specifically includes the following steps:
S1, prepare the veneer steel plate that brightness is 5.5 ° -6 °, clean veneer surface of steel plate before each production, remove surface impurity,
Then it is water stain stand-by that veneer surface of steel plate is dried again, veneer steel plate brightness at this time almost changes less, and changing value can be ignored,
Using such veneer steel plate as the upper hot pressboard and lower hot pressing board in hot press；
S2,0 ° of melamine-impregnated finishing paper after melamine glue and additive dipping is mated formation in substrate surface, group
At plate embryo, it is then fed into hot press and carries out the work of hot pressing veneer, substrate thickness 3mm, at this time when hot pressing through upper lower hot pressing board
Between be 30-40 seconds；During hot pressing, the veneer pressure that upper lower hot pressing board applies 0 ° of melamine-impregnated finishing paper and plate embryo is
13MPA, and the temperature setting of upper lower hot pressing board is 190-200 DEG C；
After S3, hot pressing veneer, the extra trimming in shearing board falling embryo edge, and the disintegrating slag and paper scrap of plate embryo surface are cleared up, it obtains
The assembled panel of melamine paper is posted；
It is S4, the plate face of two assembled panels is opposite, it is smooth to be placed in straight sheet pile, slow cooling is carried out to assembled panel, eliminates patch
The stress that face steel plate veneer generates.
In a preferred embodiment, in the step S2, the temperature difference between upper hot pressboard and lower hot pressing board is
2-3℃。
In a preferred embodiment, concretely particieboard, middle density are fine for substrate used in the step S2
Tie up plate or hardboard.
In a preferred embodiment, in the step S2, when the veneer on the substrate with a thickness of 4mm, hot pressing
Time is 40-45 seconds.
In a preferred embodiment, in the step S2, when the veneer on the substrate with a thickness of 16mm and 25mm
When, hot pressing time is 46-50 seconds.
In a preferred embodiment, in the step S4, guarantee that temperature is 18-22 in environment locating for straight sheet pile
DEG C, humidity is 50% -60%.
Technical effect and advantage of the invention:
1, the process of production technology of the present invention is identical with common melamine facing, but technological parameter is different from other patterns,
The veneer steel plate for being 5.5 ° -6 ° by preparing brightness, as the upper hot pressboard and lower hot pressing board in hot press after cleaning out；It connects
0 ° of melamine-impregnated finishing paper is mated formation in substrate surface, carry out hot pressing, different hot pressing is arranged in different substrate thickness
Time, and guarantee that veneer pressure is 13MPA, hot pressing temperature is 190-200 DEG C；Then to cleared of debris corner after hot pressing；Finally
Obtained finished product is cooled down and eliminates stress, veneer is completed, entire processing technology high yield rate, and finished product stability and quality are all very
It is high；
2, the setting of technological parameter through the invention, obtained melamine panel yield rate is higher, and is not in bending,
Hardness is low, and situations such as scratch occurs；And high stability, compare existing product, it is more acidproof, alkaline-resisting, resistance to it is fire-retardant,
Scratch-resistant；The soft light of the existing 0 ° of matt impregnated paper of obtained finished product, guarantee make light in diffusing reflection or scattering.
