Description
Technical field
The present invention relates to the colloid emulsion of the nano material of a kind of indoor wall and furniture surface spraying, particularly relate to a kind of organosilicon composite photo catalyst emulsion, belong to building material technical field.
Background technology
After interior decoration, the chemical pollutant such as ammonia of the benzene homologues in the formaldehyde in tackiness agent, paint, body of wall release can long-term slow releasing, constitutes a serious threat to indoor occupant health.People stays for some time and can feel dizzy, dizzy, breathes uncomfortable in room, directly affect the healthy of indoor occupant, so carrying out the comprehensive regulation to indoor environment after fitting up, is a urgent health engineering.
In prior art, improve indoor environment to remove ski dome, the products such as solid activated carbon, photocatalyst, dissolve formaldehyde enzyme are current more widely used products.Mainly remove chemical pollutant by the mode of absorption, owing to not being oxidized, the chemical reaction such as decomposition, so elimination effect is uncertain.
The main component of photocatalyst is titanium dioxide.Electric charge can be produced under sunlight or uviolizing, react with the water molecules in air and oxygen molecule, produce negative oxygen ion and hydroxide radical free radical, the oxidation capacity that these material tools are superpower, ski dome material can be made oxidized, also the cell walls of virus and bacteria can be made to be destroyed, to reach the object removing indoor chemistry and biological pollution.This kind of medicament adopts the mode of tackiness agent that these nano particles are pasted onto body surface usually, forms thin film.But, the coefficient of thermal expansion and contraction of the coefficient of thermal expansion and contraction of this layer film and furniture and wall surface is impossible identical, because furniture and paint for wall vary, so common film technique can come off along with the prolongation film of time, after friction, film formation surface also can be destroyed, and causes medicament to lose efficacy.
Dissolve formaldehyde enzyme is the medicament of more common removing ski dome.In use procedure, in order to coordinate the reaction conditions of the reagent such as dissolve formaldehyde enzyme, need to adopt acidic solution environment.This kind of acid reagent needs to protect metal parts when spraying furniture, because the positions such as folding, screw, metal finish paint are after contact acid medicine, can produce corrosion, and the cost of labor doing to protect is more than three times of spraying cost of labor, and construction cost is high.In spraying process, produce a large amount of acid aerosol and fill the air whole room, have strong impulse smell, serious harm workmen's is healthy.
As can be seen here, remove at present the product of indoor environment chemistry, biological pollution, there is certain weak point, needing technical progress is improved.
