Description
Technical field
The present invention relates to a kind of novel dry powder type interior wall coating being main component with oyster shell whiting and nanometer inorganic filler and polymer powder material with adsorption-decomposition function obnoxious flavour and peculiar smell, antibacterial, sterilization, anti-static function.The invention solves that current interior wall coating cost is high, energy consumption is large, itself there is the shortcoming polluting and can not purify indoor harmful gas.Prepare the coating having and have adsorption-decomposition function obnoxious flavour and peculiar smell, antibacterial, sterilizing function.
Background technology
The dope for inner wall of architecture that market uses mainly emulsion paint.Emulsion paint ubiquity the shortcomings such as paint film is soft, time of drying is long, package stability is poor, and after being moistened, easy breed bacteria, the phenomenons such as generation comes off, variable color, have a strong impact on work-ing life and indoor beauty to emulsion paint class coating.The oil that the consumption of emulsion paint class coating is a large amount of simultaneously, due to China's oil resource shortage, need a large amount of import, material cost improves year by year.Chinese society expanding economy adds the demand of coating, and improves the requirement of people for coating use properties.In interior decoration process, containing a large amount of volatility toxic compounds in the finishing material such as paint, milky white adhesive, composition board, foam insert of a large amount of use, the health of the toxic and harmful serious harm mankind that these toxic compounds slowly volatilize and living environment.Environmental protection and functionalization are the future thrusts of indoor architectural paints, and introduce nanometer system and use natural materials also just to become the new development trend of paint field.
Oyster shell whiting to propagate artificially with natural shell by making after high-temperature calcination, pulverizing.Its moiety is the calcified materials such as calcium carbonate, calcium oxide, calcium hydroxide, and this is as vesicular, has absorption, the effect of decomposing (formaldehyde, benzene, TVOC, ammonia) and adjusting air humidity, elimination odor function.The compound of calcium is used for deodovization agent in life, therefore the assorted taste of smell and indoor that oyster shell whiting can distribute indoor smoke, infant, patient, pet, mould all has effectively dispels effect, especially has adsorption to the carbon monoxide that cigarette distributes in indoor with the Dust Capacity that swims.Its composition of oyster shell whiting 100% is calcium, therefore has good antistatic performance.The oyster shell whiting simultaneously fired and titanium dioxide and tourmalinite nano-powder have extremely strong antibacterial and germicidal action to the various bacteria comprising intestinal bacteria, Salmonellas, yellow glucose fungus etc., and have function that is anticorrosion, mildew-resistant.Be base material with oyster shell whiting, then be equipped with interior wall coating that the titanium dioxide of a certain amount of cobalt-60γray radiation treatment and tourmalinite nano-powder and polymer powder material makes and will there is good absorption obnoxious flavour and antibacterial, sterilization, anti-static function.Metope use to have that film is plentiful, texture is natural after shell powder paint, firm soft and smooth, fashion is graceful.Pollution resistance is good.Its construction versatility is good, and be as good as with emulsion paint, be applicable to and scrape, roll, brush, sprays various constructional method.High comprehensive performance.
Shell powder paint " be the typical industry product of recycling economy, " resource-product-waste-renewable resources " closed loop economic process, in production and consumption process, realizes the minimizing of waste, resource utilization and innoxious.Shell is a kind of edible resource, and it, after cannery's processing, becomes a kind of edible product.Empty shell has but become a kind of waste, is dropped and pollutes environment on the beach.The contribution of " shell powder paint " is just this waste renewable resources.The main raw material of " shell powder paint " is shell is the byproduct that modern farming causes, and there are very long shoreline and vast marine site in China, the Shells in the seabed, coastal waters of 1 years, almost same with marine site vast.Because it does not use petroleum product additive, so it is nontoxic pollution-free product.Product cost is 1/10-1/20 of similar quality emulsion paint, be a kind of advanced person, with eco-friendly production key technology, it meets novel process and the new technology of recycling economy fundamental principle completely.It is the Green Revolution of coatings industry, has fabulous prospect.
Summary of the invention
