Description

There is the water paint of self-cleaning, anti-mildew, sterilizing and air purification effect
Technical field:
The present invention relates to a kind of water paint, particularly relate to there is self-cleaning, anti-mildew, sterilizing and air purification effectWater paint.
Background technology:
Since reform and opening-up, along with the rapid growth of China's national economy, improving constantly of people's living standard, is coated withMaterial output and consumption be just with speed increment faster, and China has become second-biggest-in-the-world coating country of consumption, annual production at presentApproximately 600 tons are reached. But than developed country, the consumption structure of China's coating is also unreasonable, high pollutionCoating variety still occupies larger ratio, and environment and workmen are brought to serious harm. Along with the change of global climateThe day of change and resource, the energy is becoming tight, and countries in the world have been formulated strict environmental regulation and policy in succession, encourage and push awayThe wide new product that uses environmental protection, energy-saving material-saving. Oligosaprobic water paint, powdery paints, high solid coatingAnd radiation curable coating has become the developing direction of coating technology. Water paint is than other low Contamination Coatings, byCan realize in having that technological approaches is many, wide application, safety, construction relatively simply form headed by selection kind, more wideLarge coating scientific and technical personnel concern and coating user's favor, has recently obtained certain development in China, before being subject toNot some attention, but water paint is except building coating field is widely used, at other field particularlyIndustrial coating field, is still solvent based coating and rules all the land, and water paint also only accounts for very little ratio.
Topmost its feature of environmental protection that is characterised in that of aqueous architectural coating, water is as the decentralized medium of coating, nothing ownMalicious, tasteless, not can to human body and environment cause harmful effect (by comparison most organic solvents can be to environment andHuman health has a negative impact); Secondly, it is evident that being easy to get property and the inexpensive property of water. As for coating propertyBecause the difference of kind is different. According to different sorting techniques, can obtain different aqueous architectural coating kinds.For example, according to the difference classification of film forming matter state in water, can be divided into water soluble paint and water milk type coating; RootAccording to the difference classification of coating constituent, can be divided into organic architecture coating and inorganic architectural coatings; According to coating appearanceThe difference classification of form, can be divided into liquid building coating and powdery building coating etc.
Publication number is CN103275543B, within open day, is 2014.06.25, applies for that the China that people is Luoyang Institute Of Science And Technology is specialProfit application discloses " a kind of preparation method of the water paint that can be used for formaldehyde and toluene gas degraded ", with natural micro-Pore structure nonmetallic mineral is raw material, adopts the methods such as scouring, acidleach, calcining to purify to mineral, with what purifyMicropore nonmetallic mineral is carrier, taking inorganic titanium salt as presoma, adopts the low temperature neutralizing hydrolysis precipitation method to prepare nanometer twoTitanium oxide composite photocatalyst material, taking prepared nanometer titanic oxide composite photochemical catalyst material as filler, preparing canFor the water paint of formaldehyde and toluene gas degraded. The coating that the method is prepared, containing volatile organic compoundThe harmful substances such as thing, formaldehyde, toluene, and effectively degradation of formaldehyde and toluene gas, the degradation rate of PARA FORMALDEHYDE PRILLS(91,95) can reachMore than 80%, can reach more than 35% the degradation rate of toluene. This coating is mainly harmful to gas by nano titanium dioxide degradableBody, its defect is that nano titanium oxide need to irradiate and could produce photocatalysis in the ultraviolet ray of sunshine, at wet weatherMore difficult playing a role under weather, therefore actual degradation effect bad, and also this coating is in self-cleaning, anti-mildew, sterilizing etc.Aspect is also very undesirable.
