Description

A kind of automatically cleaning decorative veneer based on photocatalysis super-hydrophobic coat
Technical field
The invention belongs to wood processing fields, and in particular to a kind of automatically cleaning decoration based on photocatalysis super-hydrophobic coat is thin Wood.
Background technique
With the continuous development of China's ornament materials industry, decorative veneer not only alleviates China treasure by big well known The imbalance between supply and demand of your timber, decorative effect are also far superior to common impregnated paper veneer, PVC veneer.But decorative veneer itself Just have the attribute of timber, is a kind of porous material and there is anisotropy, the booty itself being easy in absorption air utilizes Wood product surface made from decorative veneer needs constantly cleaning, influences its service life and increases the cost of final-period management.Cause This assigns its automatically cleaning, anti-corrosion and waterproof and other performances by being chemically or physically modified to artificial decoration veneer surface It is of great significance.
Currently, imitating some natural phenomenas to solve the problems, such as the technology of mankind's real life increasingly by the wide of people General concern, self-cleaning surface technology are exactly one of them.There are many examples with excellent self-cleaning surface in nature, Such as " wing of butterfly ", " leaf of cabbage " and " lotus leaf effect " etc..In recent years, with the extensive use of new material, It carries out self-cleaning surface coating processing technology to these materials to be also increasingly taken seriously, automatic cleaning coating, which refers to, is attached to painting Pollutant, dust of layer surface etc. can voluntarily fall off or through coating under the external forces such as gravity, wind-force, rain drop erosion A kind of surface of surface particular matter degradation of contaminant, be generally divided into 1), super-hydrophilic coating: water droplet will be spread out on the surface Water membrane, contaminant particle can be attached on moisture film, prevent it from directly contacting with surface, with the flowing of moisture film, pollutant It will be washed, and reach self-cleaning effect；2) super-hydrophobic coat: it cleans the process that mechanism is similar to lotus leaf surface decontamination, water When drop is slided or rolled on the surface of the material, the dirt of material surface is adsorbed on water drops surface, and taken away material surface, Reach self-cleaning effect.And for both self-cleaning modes, it is main related with wettability of the surface.Drop on the surface of solids Equilibrium configuration determines i.e. (solid gas, solid-liquid, liquid gas interface), when meeting Young's equation, the drop on surface by three phase boundary tension Shape reaches stable.
That is: γsg-γsl=γlgcosθ
In equation, only when drop is very small (millimeter to micron level), gravity is ignored, at this moment, liquid Approximate spherical hat shape, liquid gas interface and the surface of solids intersect drop on the surface, and the angle angle θ, θ is the practical leaching of drop Moisten angle.
Young's equation is the basis of all wetting phenomenas, and in most cases, drop and surface are in partially wetted phenomenon；When The sum of solid-liquid interfacial tension and liquid gas tension are intended to 0 degree in the practical angle that infiltrates when being equal to solid gas interface tension, at this time on surface Drop will spread into thin film out, i.e., full wetting.On the contrary, if drop will use up on surface when practical infiltration angle is 180 degree Possible to gather, surface is nonwetting.
Commonly prepare automatic cleaning coating method have Sol-gel (sol-gel method), plasma method, electrodeposition method, Polymer, nanoparticle method, magnetron sputtering method etc..But above-mentioned preparation method long preparation period, equipment cost is high, energy consumption height, ring Border pollution is big, and obtained coating self-cleaning effect is unobvious.The present invention provides a kind of certainly clear based on photocatalysis super-hydrophobic coat Clean decorative veneer and preparation method thereof, utilizes nano-TiO2It is blended with hydrophobic nano particle, it is thin to be coated uniformly on decoration The surface of wood, is formed on its surface the coating of super-hydrophobicity, so that woodwork has long-term self-cleaning function, after reducing The management cost of phase, improves value-added content of product.
Summary of the invention
To solve the pollutant that existing decorative veneer surface is easy in absorption air, wood product surface obtained needs not Disconnected cleaning influences its service life and increases the cost of final-period management, and existing automatically cleaning technology long preparation period, equipment At high cost, energy consumption is high, environmental pollution is big, and self-cleaning effect is not significant, is not suitable for the defects of large area uses.The present invention provides A kind of automatically cleaning decorative veneer based on photocatalysis super-hydrophobic coat, utilizes nano-TiO2It is blended with hydrophobic nano particle, It is coated uniformly on the surface of decorative veneer, is formed on its surface the coating of super-hydrophobicity, so that woodwork has long-term Self-cleaning function reduces the management cost in later period, improves value-added content of product.
The technical solution adopted by the present invention to solve the technical problems is:
