A kind of heat-insulation thermal-insulation water-based paint with air purification function
Technical field
The present invention relates to building material field, particularly a kind of heat-insulation thermal-insulation water-based paint with air purification function.
Background technology
Energy saving building is a kind of effective way improving building energy service efficiency, and the method used by material of construction heat preservation energy-saving is generally use energy-saving and heat-insulating material or outside the building wall and/or interior wall coating thermal insulation coatings.But in China, the energy-saving and heat-insulating material that major part adopts is organic substance, as polystyrene foamed plastics, urethane foam etc., and these material resistivity against fire extreme differences, easy melting, even can also produce toxic gas when catching fire.
In existing heat insulating coatings, a lot of organic solvent that adopts is as solvent, and this can cause serious room air pollution, brings hidden danger to the health of people.Although also have some with aquosity heat insulating heat preserving paint, this kind of coating function is relatively single.
For above situation, study that a kind of to have the heat-insulation thermal-insulation water-based paint improving the functions such as Air quality, adjusting air humidity, mildew-resistant, antisweat, fire prevention just significant.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has the heat-insulation thermal-insulation water-based paint improving the functions such as Air quality, adjusting air humidity, mildew-resistant, antisweat, fire prevention.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of heat-insulation thermal-insulation water-based paint with air purification function of the present invention adopts following weight percent formula.

Deionized water surplus.
The particle diameter of hollow glass micropearl of the present invention is 10 μm ~ 100 μm.
It is with Cubic zirconium phosphate for carrier that zirconium phosphate of the present invention carries silver powder, is distributed to equably in the structure of zirconium phosphate by silver ions with stable form, its median size D
50≤ 1000nm, silver content>=3.0%.
Nano zine oxide of the present invention is the nano zine oxide of crystal whisker-shaped, its median size D
50≤ 30nm.
Preparation method of the present invention comprises the steps.
Take deionized water in proportion and put into a container, then add Vltra tears, dispersion agent 5040, alcohol ester 12 film coalescence aid, 1,2-PD, Kathon CG and silicone antifoam agent and disperse.
Take diatomite in proportion, lignocellulose, zirconium phosphate carry silver powder, nano zine oxide, tourmaline powder and aluminium sesquioxide, and be added in the dispersion liquid of previous step and continue dispersion.
Take pure acrylic latex and hollow glass micropearl in proportion and in dispersion liquid, continue dispersion, by filling liquid, packaging after stirring.
Product majority of material of the present invention is inorganic materials, and adds fire-retardant material aluminium sesquioxide, and product has fire-proof function.The hollow glass micropearl that product of the present invention also adds, it has extremely low thermal conductivity, can reduce the thermal conductivity of coating, can play good thermal insulation function.In addition, product of the present invention has functions such as improving Air quality, adjusting air humidity, mildew-resistant, antisweat, fire prevention.
