Description
[technical field]
The invention belongs to redwood technical field of aqueous paint, it is related to a kind of redwood Environmental Protective Water-paint and preparation method thereof.
[background technique]
In today of pay attention to day by day coating safety and environmental protection index, aqueous woodware paint is just because of its less harmful, low
Polluting property is gradually received by market.The furniture lacquer that coatings enterprises are shown in Furniture Exhibition is substantially mainly three classes: PU paint,
UV paint, water paint.Instantly low-carbon environment-friendly theory is prevailing, and furniture industry and furniture lacquer industry are no exception.Furniture lacquer is as furniture
The important supplementary material of industry, the low-carbon environment-friendly that quality directly affects furniture industry are horizontal.In China Furniture Industry, house is exported
Tool occupies very big specific gravity, and the U.S., European Union and Japan, which have all put into effect, to be limited and be forbidden to use the related of solvent wood coatings
Regulation, this also promotes the furniture enterprise of China that must focus on furniture environmental protection.Although current China policy does not have clear stipulaties cannot
Using solvent based coating, but with the continuous development of technology with the continuous promotion of environmental protection concept, solvent based coating will gradually by
More environmentally-friendly product is substituted.At home in furniture lacquer market, PU paint still accounts for main position, and PU is painted in environmental protection technology side
Face is also being constantly progressive, but it slowly quits the stage at last as coatings volatile organic compounds.It is with fastest developing speed in furniture lacquer at home to work as
Belong to UV photocureable coating, has had and surmounted PU trend.
Current country UV coating can almost accomplish solvent-free spraying, i.e. a hundred percent solid content sprays.Although water paint
Occupation rate at home in furniture lacquer market is also very low, but its safety, the feature of environmental protection are the trend of the following furniture lacquer development, with
The occupation rate of market of the aqueous furniture lacquer of continuous development of technology will be higher and higher.Environment protection type functional water-borne wood coating will have
Good market prospects.
[summary of the invention]
In order to overcome the technological deficiency of the prior art, technical problem to be solved by the present invention lies in provide a kind of environment-friendly type
