Description
Technical field
The artificial decoration material field of the present invention, more particularly to a kind of resist blocking and that carry clean wood-based plate facing paper and its system
Preparation Method.
Background technology
People's holds in environment, working environment and living environment that there are the organic pollutions pair such as a large amount of bacterium and formaldehyde
The health of people brings serious harm.In recent years, with the improvement of living standards, people increasingly pay close attention to the prevention of disease
And control, improve household working environment into public urgent expectation and needs, this has been greatly facilitated clean environment firendly ornament materials
Technology development.Wherein artificial decoration paper occupies component and status in home decoration, but the facing paper of industry still has matter
Also in the exploratory stage in terms of throughput bottleneck, especially environment-friendly function modification, product in the market is difficult to fully meet the need of people
It wants.
In the production technology of melamine impregnated paper, because the process characteristic of itself is not complete in urea-formaldehyde glue and melamine glue
Contain a large amount of hydrophilic radical, such as hydroxyl before all solidstate（-OH）And amino（-NH2）, hydrophilic radical is easy to be absorbed in air
Moisture makes Lauxite and melamine resin be partly dissolved, and makes the good last layer paper of stacking under the effect of gravity
Bottom and next layer of recto generate adhesion, cause to be not readily separated or tear the quality problems scrapped.In clean environment function
Modified aspect, usual way adds photocatalyst material such as nano-tourmaline in the melamine gluing agent that surface is coated at present
Or titanium dioxide, wherein nano-tourmaline or titanium dioxide discharge anion, decompose noxious pollutant under the action of uv light
With the bacterium on kill surface and in air.And traditional photo-catalytic nano tourmaline or pure nano titanium dioxide powder, only
400nm ultraviolet lights below can be absorbed, in a natural environment, ultraviolet light occupation ratio is relatively low, and the 10% of insufficient natural light, that is, it receives
Rice tourmaline and titanium dioxide need under intense UV rays, could dissociate anion to decomposing volatile organic matters and kill
Bacterium, but interior, often without so strong light source, the Environmental insults that open ultraviolet radiator are harmful again, so commonly
The automatic cleaning action that plays indoors of photocatalyst it is seldom.
Invention content
It is an object of the invention in view of the above shortcomings of the prior art, provide a kind of photocatalyst suspension and surface spraying
There is self-cleaning wood-based plate facing paper of the resist blocking and that of the photocatalyst suspension and preparation method thereof.
The technical solution used in the present invention is：A kind of nano-titania photocatalyst suspension, by weight by
The following raw material group is grouped as：
Component A：10 ~ 30 parts of nano-titanium dioxide；
1.5 ~ 3 parts of nano graphene oxide；
1 ~ 4 part of dipropylene glycol；
0.05 ~ 0.2 part of Polyether Modified Polysiloxanes Defoaming Agent；

0.1 ~ 0.3 part of monoethanolamine；
45 ~ 58 parts of water.
Specifically, photocatalyst suspension of the invention is using feature possessed by nano-titanium dioxide electronic structure, when it
After absorbing the energy in sunlight or other light sources, the electronics of particle surface is activated, and escapes from original track, while surface is given birth to
At positively charged hole.There is the electronics of effusion strong reducing property, hole then to have strong oxidizing property, and the two and the aqueous vapor in air are anti-
Ying Houhui generates the very strong superoxide anion radical of chemical activity and hydroxyl free radical.Active oxygen, hydroxyl free radical
On the one hand can have to reach degradation by oxygenolysis such as majority of organic pollutants, foul smell at harmless carbon dioxide and water
The effect of machine pollutant, on the other hand when encountering bacterium, the cell of direct attack bacteria causes the organic matter in bacterial cell
Degradation, kills bacterium, and be allowed to decompose with this.Meanwhile nano-titanium dioxide belongs to non-dissolving type material, in degradation organic contamination
Object and while kill bacterium, itself does not decompose, does not dissolve out, condition needed for photocatalysis effect is low, persistent, has lasting kill
Bacterium, degradation of contaminant effect.
The photocatalyst suspension of the present invention be utilized simultaneously nano-graphene itself to it is thin, to it is hard, with excellent heat conduction
The characteristics of property and electric conductivity.Nano-graphene resistance capacity to deformation size modulus under outer stress can reach 1T（1012）
Pa.The intensity of ability of resisting destruction size is 130G when reflecting nano-graphene stress（（109）Pa.The thermal conductivity of nano-graphene
Rate reaches 5000W/（m-k）, the unique carrier properties of nano-graphene make its electron mobility reach 2 × 105cm2/（V-s）,
More than 100 times of silicon, and change little with temperature change.The present invention adds nano oxidized in nanometer titanium dioxide coating
Graphene plays the catalyst action of photocatalyst, and addition latter aspect can effectively increase nano-titanium dioxide and absorb visible light
Wave-length coverage plays better bactericidal potency, on the other hand since nano-graphene is excellent to increase the dissociation quantity of anion
Different electric conductivity assigns the anlistatig function of coating, reduces the attachment of grieshoch dirt.Again because of nano-graphene to thin, a Yang departments
（Close 28.3455 grams）28 football pitchs of covering can be extended, in addition hydrogenation of six carbocyclic non-polar conformations and the feature to heavily fortified point, addition are a small amount of
Nano-graphene can just make coating have high rigidity damage resistant, nonhygroscopic resist blocking and that effect.

Preferred 5069 dispersants of SAMA of the present invention, it is a kind of dedicated dispersant with high efficiency of titanium dioxide of German Sa Masuo, can be helped
Titanium dioxide granule is separated into fine ion under the action of shearing force and can settle out.
In addition, the alkali soluble in B component of the present invention rises, acrylic acid thixotropic agent is in water because the effect of hydrogen bond forms stereoscopic graticule
Shape structure effectively can prevent titanium dioxide from settling；And acetylenic diols wetting agent can play the dynamic static surface for reducing suspension
The effect of power is conducive to surface levelling when spraying.
A kind of preparation method of nano-titania photocatalyst suspension as described above comprising following processing step：
By each raw material in component A mix after high speed dispersion 30min through stick tip formula sand mill grind twice it is spare, by the alkali soluble of B component
