A kind of production technology with the high light melamine decorative veneer of wood effect
Technical field
The present invention relates to decorative panel processing technique field, particularly a kind of production technology with the high light melamine decorative veneer of wood effect.
Background technology
At present, melamine decorative veneer is that different colours and texture printing paper are immersed melamine resin adehsive, then through partially cured, then is posted hot pressing in particieboard, density board and forms, can be made into composite floor board, the ornament materials such as household sheet material.Melamine decorative veneer can copy various pattern arbitrarily, color is beautiful, hardness, anti-wear performance excellence after impregnation, but due to printing grammes per square metre compatibility corresponding spread must be considered during impregnation, so traditional printing paper infiltration melamine resin adehsive ratio is not high, cause decoration panel texture vivid effect, plumpness and solid wood still by certain gap.Although some technology introduction crosses the melamine decorative veneer produced by the method for cyanurotriamide modified or simple interpolation brightener, still can not reach real high glaze or high emulation effect through Market Feedback, and Lacquer finish spraying paint easily ftractures to melamine decorative veneer poor adhesive force.
Summary of the invention
In order to solve the problem of prior art, embodiments provide a kind of production technology with the high light melamine decorative veneer of wood effect.
Described technical scheme is as follows:
There is a production technology for the high light melamine decorative veneer of wood effect, comprise following operation:
A, by melamine, formaldehyde, diethylene glycol, methyl-silicone oil, polyethers, silane coupler react make modified cyanurotriamide methylal resin;
B, printing paper flood above-mentioned modified cyanurotriamide methylal resin, the total spread of modified cyanurotriamide methylal resin to printing paper controls at 145%-155%, impregnation one soaks and controls the 55%-60% that spread is total spread, and impregnation two soaks and controls the 40%-45% that spread is total spread; Impregnation speeds control, at 20 ms/min, by nine joint oven for drying after the modified cyanurotriamide methylal resin described in printing paper dipping, then obtains modified cyanurotriamide methylal resin layer through the cooling of chill roll and conveyer belt;
C, carry out hot pressing with particieboard and modified cyanurotriamide methylal resin layer, be cooled to normal temperature, health 15 days, carries out grinding process;
D, on the modified cyanurotriamide methylal resin layer after polishing, spray silane coupler, then to dry in 50 degree of baking ovens, spray paint, dry.
In step B, the total spread of modified cyanurotriamide methylal resin to printing paper controls 145%, 150% or 155%.
In step B, it is 55%, 58% or 60% of total spread that impregnation one soaks control spread.
In step B, it is 40%, 42% or 45% of total spread that impregnation two soaks control spread.
In step D, the finish paint of spraying is solid content is the polyurethane finish of 46%, the acrylic acid top-coat of solid content 47% or solid content are 40%UV UV-curable finish coat.
The present invention introduces part silane coupler in modified cyanurotriamide methylal resin, adds the binding ability of the inorganic matter such as resin glue and fibrage, adds the binding ability with Lacquer finish finish paint simultaneously.In immersing glue process, increase nozzle quantity and gas output in baking oven by extending baking oven length, adjustment nozzle angle, breach traditional handicraft cannot improve merely spread, cannot the problems such as drying and forming-film.Before spray Lacquer finish finish paint, bridging agent spray treatment is carried out to modified cyanurotriamide methylal resin layer, add the finish paints such as polyurethane polyureas acrylic acid to the adhesive force of modified cyanurotriamide methylal resin layer, ensure that product high glaze shortly, high richness solves the disadvantages such as paint film cracking comes off simultaneously.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment one
A kind of production method and technique with the high light melamine decorative veneer of wood effect:
1. reacted made modified cyanurotriamide methylal resin by melamine, formaldehyde, diethylene glycol, methyl-silicone oil, polyethers, silane coupler.
2. in printing paper dipping modified cyanurotriamide methylal resin layer, the total spread of modified cyanurotriamide methylal resin to simulated grain paper controls 145%, it is 55% of total spread that impregnation one soaks control spread, and it is 45% of total spread that impregnation two soaks control spread.Impregnation speeds control is at 20 ms/min, and printing paper, also will through the property melamine formaldehyde resin layer of lowering the temperature to obtain of chill roll and conveyer belt after dipping modified cyanurotriamide methylal resin is by nine joint oven for drying.
3. carry out hot pressing with particieboard and modified cyanurotriamide methylal resin layer, be cooled to normal temperature, health 15 days, carries out grinding process.
4. on the modified cyanurotriamide methylal resin layer after polishing, spray silane coupler, then dry in 50 degree of baking ovens, spraying solid content is 46% polyurethane finish, carries out drying both obtaining product of the present invention.
Embodiment two
It is characterized in that: a kind of production method and technique with the high light melamine decorative veneer of wood effect:
1. reacted made modified cyanurotriamide methylal resin by melamine, formaldehyde, diethylene glycol, methyl-silicone oil, polyethers, silane coupler.
2. in printing paper dipping modified cyanurotriamide methylal resin layer, the total spread of modified cyanurotriamide methylal resin to simulated grain paper controls 150%, it is 58% of total spread that impregnation one soaks control spread, and it is 42% of total spread that impregnation two soaks control spread.Impregnation speeds control is at 20 ms/min, and printing paper, also will through the property melamine formaldehyde resin layer of lowering the temperature to obtain of chill roll and conveyer belt after impregnated melamine methylal resin is by nine joint oven for drying.
3. carry out hot pressing with particieboard and modified cyanurotriamide methylal resin layer, be cooled to normal temperature, health 15 days, carries out grinding process.
