The coating comprises the following raw materials in percentage by weight: 20-40 percent of silicone-acrylic emulsion or ethylene-acrylic acid copolymer emulsion, 1-5 percent of anatase-phase nano-titanium dioxide, 2-2.5 percent of negative ion generating material, 1-2 percent of wetting agent, 0.5-1 percent of dispersing agent, 1 percent of preservative, 1 percent of pH regulating agent, 1-2 percent of anti-freezing agent, 1-2.5 percent of diatomite, 1-2 percent of film forming aid, 1-2 percent of thickening agent and the balance of water. In the coating, a photocatalysis material and the negative ion generating material are used, so that indoor air pollution can be eliminated effectively, and the coating has the advantages of stable lasting effect and avoidance of secondary pollution.
Description
Technical field
The present invention relates to interior decoration and use coating, particularly a kind of environmental-protective light catalyst interior wall coating with fresh air.This coating is through composite with photocatalyst material and anion-generating material, solved present coating function singleness, to the shortcoming of room air regulation effect difference.
Background technology
The pollution of house decorative material and furniture is the main aspect that causes room air pollution at present, contains volatile organic compounds (TVOC) up to kind more than 300 in the materials such as paint, wood veneer, shaving board, foam stuffing, interior wall coating, plastic facing.Toxic gas such as the formaldehyde that finishing material discharges, ammonia, benzene class and indoor various mould, virus, peculiar smell serious harm to people's healthy, living environment etc.According to statistics, indoor environmental pollution has caused 35.7% respiratory tract disease, 22% chronic lung disease and 15% trachitis, bronchitis and lung cancer.
Along with the enhancing of fast development of national economy and environmental consciousness, people are to interior decoration, finishing material, and especially the requirement of interior wall coating security is also increasingly high, and the improvement of domestic environment is imminent.But, generally hide former scent of in the prior art through fragrant agent such as air fresheners.This method can not be dispeled harmful substances in air veritably.It is less that at present the topcoating of finishing material and furniture is not only removed the ability of obnoxious flavoures such as formaldehyde, benzene, radon, and lasting effect is unstable, may cause secondary pollution.
Transition of electron takes place in photocatalyst material under the irradiation of light sources such as sunlight, fluorescent lamp; The valence band electronics is excited to conduction band and on valence band, produces the hole; Make airborne oxygen and water molecule activation; Produce the active oxygen and the radical of tool high reaction activity, and be released in the air microorganisms such as bacterium are killed and Decomposition, play the purpose that purifies air.
The permanent electric field that anion-generating material forms produces faint electrolytic action through its electrode pair air and water molecules and produces the hydroxyl negative ion, and oxynitride, ammonia, benzene, formaldehyde etc. are had the effect of well dispeling.The polarity tourmalinite is exactly one type of anion-generating material like dravite, iron tourmaline, elbaite etc.It is a kind of silicic acid rock mineral, and its chemical ingredients is silicate, boron, magnesium, aluminium etc., and it has piezoelectricity and pyroelectricity.The polarity superfine tourmaline powder can continue permanent release negative ion and emitting far-infrared, and can produce 0.06 milliampere bioelectric current, purifies air.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is, removes the obnoxious flavour ability for solving to fit up with coating in the prior art; The problem that stability is bad; The present invention provides a kind of photocatalyst air freshing interior wall coating and preparation method thereof, and this coating has used photocatalyst material, anion-generating material, and pollution can effectively purify the air of a room; It is stable to have lasting effect, stops the advantage of secondary pollution.
The present invention provides a kind of environmental-protective light catalyst interior wall coating with fresh air; It is characterized in that: raw materials used weight percent is: the nano titanium oxide 1-5% of organosilicon crylic acid latex or PEMULEN TR2 emulsion 20～40%, anatase octahedrite phase, anion-generating material 2～2.5%, wetting agent 1-2%, dispersion agent 0.5～1%, sanitas 1%, PH regulator 1%, frostproofer 1～2%, zeyssatite 1～2.5%, film coalescence aid 1～2%, thickening material 1～2%, surplus are water.
