Description
Technical field
The present invention relates to a kind of indoor paint and production method thereof, particularly a kind of colorful coating for purifying indoor air and production method thereof.
Background technology
Building coating is gorgeous with its rich color, construction safety is convenient, be easy to renovation and advantage such as with low cost; both satisfied decoration requirement to buildings; again buildings is played a protective role, therefore in the decorating inner and external walls of buildings, bearing important role.
The building coating that China produces at present mainly contains two big classes: the one, and the synthetic resin emulsion class comprises vinyl acetate-acrylic latex paint, styrene-acrylic latex coating, vinylchlorid-vinylidene chloride emulsion paint, polyvinyl acetate lacquer, epoxy-acrylic latex coating etc.; The 2nd, the inorganic polymer class mainly comprises with silicate, silicon sol serving as the various inorganic architectural coatings of basis preparation.Indoor decorative paint mainly divides two big class wall decoration lacquers and wood decoration lacquer.The wall decoration lacquer that present domestic resident uses has emulsion paint, polyvinyl alcohol coating etc.; Wood lacquer mainly uses pyroxylin(e)finish, polyurethane paint, epoxy resin-based paint, aqueous woodware paint etc., and wherein epoxy resin-based paint is mainly used in the floor application.
Along with house decorative material is used more and more widely, it is the third generation pollution period of sign that the present mankind begin to enter with the indoor pollution.Generally acknowledge that in the world indoor pollution is to the maximum place of public health harm.The characteristics of room air pollution are as follows: the obnoxious flavour that distributes in indoor building materials and the furniture, and amount of positive ions is many, and negative ion is few, CO content height, the refuse waste gas of people and animal etc.The harmful substances that mainly contains of indoor generation has the generations such as incomplete combustion by volatilization, household fuel and the tobacco leaf of material of construction, house decorative material and daily necessities of 1. formaldehyde-mainly.2. ammonia-by evaporating in finishing material, building structure such as the body of wall.3. volatile organic gas VOC-be less than or equal to any organic compound of 250 ℃ from boiling point or fusing point, as sharp paint, coating, tackiness agent, ground, decorative material for wall surface etc.4. ozone-because generations such as uviolizings, electrical equipment use.5. carbonic acid gas-human body is breathed out and the waste gas of fuel combustion.
Except utilizing natural ventilation or power ventilation to improve the Air quality, also should help the material of HUMAN HEALTH in indoor use, as indoor air purification coating.Material for air purification exists with forms such as powder, fibrous, film, particle or blocks, by the property sort of scavenging material is: 1. physisorption type scavenging material-and as activated carbon, zeolite, other silicate materials.2. chemisorption type scavenging material-have chemisorption or catalyzed reaction are main scavenging material, as being carrier with activated carbon or zeolite, quicken the scavenging material that various chemical reaction substances produce chemical reactions.3. introduce ion-exchange group in ion-exchange type scavenging material-high molecular polymer, with the ion-exchange purification air, as the ion-exchange on sulphur, the alcohol radical.4. photocatalyst material one as carrier, adds TO with glass, pottery etc.
2Deng photocatalyst material, under UV-irradiation, making water in air branch and oxygen conversion is active oxygen radical, and these free free radicals make SO then
2, dusty gass such as NO change into various innocuous gas or acids.5. negative ion activated inorganic scavenging material, this material is listed especially at this, because it except that having sorption, decomposition function, has photo-catalysis function simultaneously, its purification capacity and work-ing life, equal specific activity carbon was high more than 10 times, and is higher more than 4 times than synthetic zeolite.
