Description
Technical field
The present invention relates to a kind of preparation method of humidity controlling coating, particularly relate to a kind of antibacterial clean taste interior wall coating of multi-functional damping being applicable to various indoor.
Background technology
Atmospheric moisture is one and lives with people and produce closely-related important environmental parameter.Humidity is preserved human comfort, process of producing product, quality product and product material impact.Under low moisture environments, the respiratory system mucous membrane of people becomes dry, easily causes respiratory system disease.At many industrial sectors, can production process normally carry out, and depends on humidity to a great extent, the production of such as papermaking, precision instrument.Article are deposited in the environment of humidity, due to the erosion of mould moldy metamorphism, make metal rusting, accuracy of instrument decline, insulation parameter reduce.Deposit in overdried environment and craze and transfiguration can occur, cause financial loss.Visible, a suitable relative humidity is to the health of people, and the production of product and the preservation of article all have a very important role.
Humidity controlling coating has the effect regulating relative indoor humidity, and it does not need source of mechanical energy and mechanical means, relies on the humidity absorption and release characteristic of self to regulate the relative humidity in space.When the relative humidity in space is too high, it can absorb water vapors a large amount of in air, and humidity is reduced.When the relative humidity in space is too low, it can release the moisture absorbed in material, makes the humidity that air keeps certain.Utilize the moisture adsorption and releasing characteristic of humidity adjusting material to carry out regulating and controlling humidity, although be a kind of passive measure of control, it is without the need to any mechanical means and energy consumption, because of but a kind of regulating and controlling method of ecological property.This, for improving human settlement, the healthy growth of plant, the preservation quality improving article, the normal operation of instrument, the Sustainable development of maintenance environmental ecology, all has important using value and social effect undoubtedly.
The development of interior wall material of construction is on the basis of original decoration functions, towards the future development of " multifunction, environmental harmony ", " multifunction " refers to except decoration functions, have simultaneously " energy-conservation, regulate humidity, antibacterial and mouldproof, purify air, sound insulation, shielding unwanted electromagnetic wave " etc. healthy functions, this greatly will improve human settlement, improve the life quality of the mankind and health level.
Summary of the invention
The present invention selects diatomite, sepiolite powder, super absorbent resin to form composite humidity adjusting material, is antibacterial material for air purification with ZnOw composite additive.
