Description
Technical field
The present invention relates to a kind of coating and preparation method thereof, specifically, the present invention relates to a kind of inorganic nano paint and preparation method thereof.
Background technology
Most of synthetic paint generally all contains a large amount of organic solvents and certain toxic pigment, filler and molecule auxiliary agent is arranged, and produces " three wastes " in producing and using, and contaminate environment influences human health.
Coating is meant mainly that to atmospheric pollution the volatile matter that coating produces is discharged in the atmosphere, pollutes in production or use.Chemical substance in the coating is except that becoming membrane matrix, and all the other materials such as solvent, softening agent, additive etc. mostly are the organism of easy volatile, and have certain toxicity that these materials are the atmospheric main sources of coating pollution, are one of atmospheric primary pollution source.Organic solvent particularly, usage quantity is big, and high volatility is bigger to human degree of damage.Behind the coating application, all the organic solvent volatilization is discharged into the atmosphere.It is reported that the whole world reaches 2,000 ten thousand tons approximately to the hydrocarbon polymer of airborne release every year, wherein have 3,500,000 tons to be organic solvent in the coating approximately.Airborne quantity of solvent is above standard, and entering by breathing can the infringement human body behind the human body.As primary alconol class, the insulting neural system of ketones solvent, hydroxy methyl, manthanoate can make pulmonary toxicity form pulmonary emphysema etc.And in China, the annual turnout of coating reaches about 1,600,000 tons, and the organic solvent amount is at least more than 800,000 tons, and paint solvent is quite serious to atmospheric pollution problem.
The waste water that produces in coating material production and use does not contain a large amount of deleterious inorganic, organic compound, and is treated or enter river, river, lake after not exclusively handling, and can cause the fresh water salinize, destroys earth water resources and circulate.Heavy metal ion in the coating waste-water can deposit and enrichment at the river bed mud layer, or further polluted surface fresh water in the water that permeates the ground, and causes that Freshwater resources worsen, and have increased the weight of the crisis of Freshwater resources in the environment.
Major parts such as the not complete reaction monomer in the synthetic paint, organic solvent, additive, heavy metal ion have toxicity, and earth ecology and HUMAN HEALTH are brought great or even irreversible influence.Pollutent can enter organism or human body directly or indirectly, disturbs or the interior normal physiological function of change body, can cause population variation or minimizing.
It is main coating that China still uses solvent-borne type in industries such as woodwork coating, anti-corrosion of metal, automobile finishs, and every year, exhaust gas discharged total amount in atmosphere reached 760,000 tons more than, is engaged in the healthy of coating material production, coating spary operating worker so is subjected to very big infringement.As contain benzene or contain benzene solvent type coating operating environment benzene in air concentration and be generally tens to thousands of milligram/cubic meters, the people is in this environment for a long time, symptoms such as dizziness, headache, weak, hypomnesis, blood change appear in the lighter, and weight person causes reproducibility anaemia, leukemia etc.About 2,300 ten thousand tons of the every output of coating in the world at present, nearly 30% is solvent-borne type.Solution coating has arrived instant stage to the infringement problem of HUMAN HEALTH, and therefore, exploitation uses nontoxic " green coating " of low pollution to become world's coating industry task of top priority.
Inorganic paint can be regarded natural paint as.Traditional inorganic paint is most of makes base-material with water glass (water glass), adds solidifying agent during use and is cured, and also once the someone uses Ca (OH)
2As base-material self cure type coating.Yet its water tolerance is difficult to reach requirement, and uses construction comparatively loaded down with trivial details, and coating finished product pH value can constitute invisible injury all more than 11 to the workmen.Simultaneously, there is unsettled situation in finished product aspect storage, and as precipitation, caking etc., preservation period is extremely short, is difficult to control.Comprehensive numerous unfavorable factor, the development of inorganic paint is restricted, and the development innovation is quite slow.
Nano material is applied in the coating, can improves the performance of traditional coating, prepare new functional nano coating.Application number discloses a kind of coating that contains Nano titanium dioxide and Nano-class zinc oxide for " removing formaldehyde, antibiotic, the interior wall coating that the purifies air " Chinese patent application of " 200510027294.8 ", can dispel formaldehyde, antibiotic, eliminate electromagnetic pollution, improve room air.Yet this coating contains film coalescence aid (12 carbon alcohol ester), has volatility, and is harmful, and volatilization is slower, and residual period is longer, is unfavorable for environmental protection.
The present inventor finds, magnesium hydroxide is added coating, can absorb airborne CO after the coating film forming
2, be converted to water-fast magnesiumcarbonate, reduce indoor CO simultaneously
2Content.
Therefore, the object of the present invention is to provide a kind of environment friendly inorganic coating and preparation method thereof with light purification, sterilization, removal foreign flavor indoors function.
