Description
Technical field
The present invention relates to a kind of paint fields, and in particular to a kind of woodenware surface applied with visible light photocatalysis functional surfaces and its
Preparation method.
Background technique
The photodegradation phenomenon that clear discovery titanium dioxide single crystalline is lauched in ultraviolet light since 1972 time chemist rattan islands
Later, photocatalysis just gradually starts the environmental pollution clean technologies as a kind of new green environment protection.It is absorbed using photochemical catalyst
Light, the enough energy of the Electron absorption of photocatalyst surface and be detached from, positively charged hole is just formed in the position of electron detachment, electricity
Son and hole and oxygen, water, hydroxyl reaction generate the superoxide ion with strong oxidizing property and the hydroxyl radical free radical with strong reducing property,
Superoxide ion and hydroxyl radical free radical make organic pollutant, bacterial oxidation be decomposed into harmless water and carbon dioxide, to reach
The purpose of decontamination and bacteria reducing.
Photocatalyst material is numerous, and it is most main at present that wherein strong, chemical stabilization is again nontoxic because of oxidability for titanium dioxide
The photocatalyst material wanted.The photocatalysis that the anti-environment-friendly water-based woodware white paint of formaldehyde smell-clearing full-effective uses disclosed in CN102146257B
Agent is nano-titanium dioxide.But titanium dioxide forbidden bandwidth is big, and photochemical catalyst just has higher only under ultraviolet light
Catalytic activity；400-700nm visible light the most main for solar energy, titanium dioxide responsiveness is weak, substantially can
In light-exposed range and do not have catalytic activity, it is very low to the utilization rate of visible light.
To improve titanium dioxide to the responsiveness of visible light, the patent of Publication No. CN102277051B is proposed in coating
It is middle with the nonmetallic method for being doped in titanium dioxide such as carbon, but the visible light-responded photochemical catalyst obtained in this way
It is weaker that there are light absorpting abilities, and catalytic activity is low, and doped chemical is easy to run off, and is easy to cause and loses catalytic activity.There is document proposition
The method of addition light-sensitive coloring agent, but light-sensitive coloring agent is as organic matter, chemical bond can also occur under photocatalysis point
Calving analysis, thus it is not durable to the responsiveness of visible light, and as time goes by, the service life of light-sensitive coloring agent gradually weakens.It is open
It number proposes the semiconductor of the addition low energy gaps width such as modified oxidized iron for the patent of CN1013756376B and realizes to visible light
It absorbs, iron oxide material refractive index is high, generally 2.8-2.9, generally only has the paint-based of 1.4-1.6 or so to specific refractivity
Material, iron oxide particle visible light is scattered it is strong, though therefore photocatalytic activity when presence visible light absorbing radiation of visible light
Not high defect.In addition there are the semiconductors that document proposes addition such as cadmium sulfide, stannic oxide low energy gap width, but exist
Certain toxicity, is unable to reach environmental requirement.
In addition, for existing light catalyzed coating, because light absorption all concentrates on the surface of coating, photocatalysis substantially
The effect of degradation is limited.How to improve the photocatalysis effect of coating is a urgent problem to be solved.In addition, organic in coating
Scission of link inevitably occurs under photocatalysis for component, including organic additive, coated body organic substrate etc., how to avoid forming a film
Coating degradations afterwards are also extremely important.
Summary of the invention
That the purpose of the present invention is to overcome the above shortcomings and to provide a kind of photocatalysis efficiencies is high, good to visible light-responded property,
Woodenware surface with long service life is applied with visible light photocatalysis functional surfaces.
