Description
Technical field
The present invention relates to a kind of surfacecti proteon nano paint, more particularly to a kind of wood surface protection nano coating and its system
Make technique.
Background technology
Wood surface is not only the principal element of the quality, use value and commodity price that determine timber-work, is also
The inno logo of people's visual sensory.Because many chemistry can occur for the influence of environment mesoclimate and biological factor, wood surface
Change and physical change, such as because of the drying shrinkage of climate change generation, bulking, cracking, distortion, the corruption of going mouldy produced under the high temperature conditions
It is rotten, produce rotten etc. is lost by worm, bacterium moth.These change procedures can not only allow wood surface lose script natural colored and
Texture, and timber can be made to be restricted in terms of utilization and processing, serious meeting jeopardizes the personal safety of people.Therefore
In order to protect the characteristic of timber, improve the decoration function and value of woodwork, it need to be protected using certain process for treating surface
The distinctive property of timber, to improve its aesthetic, mechanical property, wearability, durability, improves timber processing characteristics and imparting
The New functions such as wood surface is heat-insulated, resistance to combustion, mothproof, insulation, conduction, so as to improve the use value of timber, have widened timber
Application field, effectively improve the utilization rate of timber resources.
Up to the present, wood surface functionality improvement method mainly have wood staining, it is Wood Bleaching, wood finishing, anti-
Rotten processing, surface peening, electroless plating, surface chemistry decoration, plasma polymerization, surface active and precious wooden ultra-thin patch
Face decoration etc..Many scholars have carried out correlative study to wood surface functionality improvement.In terms of wood staining, Japan is in dyeing
At most, and the history of China's wood staining is also for a long time, such as coloring of Fujian lacquerware and the life of Suzhou mahogany furniture for achievement in method
Production is respectively provided with very rich experience.But in wood staining theory and technical elements, until the end of the eighties in last century, Chinese scholar
More systematic research is proceeded by, and achieves obvious achievement.In addition, the research to wood staining method, main to concentrate
In the dyeing of veneer.The research chitosan acetic acid such as Duan Xinfang is handled China fir sapwood, heartwood and Chinese white poplar sapwood surface, is tied
Fruit shows that the dyeing for handling material is homogeneous, and without color spot, dark, the grain of wood is also clear.
Wood preservation processing be using preservative timber one layer of Surface Creation it is nontoxic, poison, colourless, odorless isolation
Layer, plays the mothproof protective action of anticorrosive mildewproof, the wood surface after preservative treatment can still carry out covering with paint operation, so that
Extend the service life of timber.
Wood preservation processing of the prior art and wood surface cover with paint, lacquer, colour wash, etc. service life of the operation with prolonging wood
Effect, but growth over time, due to the factor of the various lesions of timber, the richness of wood surface, color saturation, texture,
Permeability and case hardness are gradually deteriorated, and unclean.Stain resistant, waterproof and the characteristic such as wear-resisting are deteriorated.
The content of the invention
For above shortcomings in the prior art, improve wood surface richness, color the invention provides one kind and satisfy
Applied with degree, texture, permeability and case hardness and with easy to clean, stain resistant, waterproof, wear-resisting wood surface protection nano
Material.
Meanwhile, present invention also offers a kind of technique for preparing wood surface protection nano coating.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：
A kind of wood surface protection nano coating, the coating includes following formula（Parts by weight）：Nano silicon 25~
27；N-butanol 25.5~26.5；Butyl acetate 5.5~6.5；Tetraethyl orthosilicate 3.5~4.5；Sodium carboxymethylcellulose 1.5~
2.5；Silane coupler 3.5~4.5；Isocyanates 15.5~16.5；Polyglycol ether 15.5~16.5.
A kind of technique for preparing above-mentioned wood surface protection nano coating, the technique comprises the following steps：
1）Ratio adds n-butanol by weight in a kettle., and nano silicon is then added while stirring, stirs
30 minutes；
2）Butyl acetate and tetraethyl orthosilicate are added reactor by ratio by weight, are stirred 1 hour；
3）Sodium carboxymethylcellulose and silane coupler are added to reactor by ratio by weight, are stirred 1 hour；
4）Isocyanates and polyglycol ether are added to reactor by ratio by weight, are stirred 1 hour, are obtained timber table
Face protection nano coating；
5）Seal filling wood surface protection nano coating, it is necessary to the filling work of sealing is completed within 1 hour.
The solution have the advantages that：The wood surface protection nano coating can be applied to furniture, building timber structure, open air
The surfacecti proteon of a variety of timber such as timber structure, timber floor；Under normal temperature, wood surface can be penetrated deep into, by protection timber table
Face forms one layer of fine and close, hard inertia diaphragm, prevents the various lesion problems of timber, improve wood surface richness,
Color saturation, texture, permeability and case hardness simultaneously have the characteristic such as easy to clean, stain resistant, waterproof, wear-resisting.
