Description
Technical field
The present invention relates to a kind of preparations and application of multifunctional nano shell powder paint, belong to building coating field.
Background technology
WHO Report, the disease of modern humans 68% are all related with room air pollution；Due to the mankind daily extremely
Rare 1/3rd time stays indoors, and indoor environment becomes the key factor for influencing human health；Report display, China
More than 70% family is there are finishing pollution, but to this shortage, correctly cognition, many people only focus on furniture, cabinet for nearly 90% family
Environmental protection, but have ignored the environmental protection of the paint for wall of occupied area maximum.
Indoor wall coating this year of environmental protection is found to be increasingly becoming the research hotspot of people, especially shell powder paint, from
It enters after the visual field of people, causes the broad interest of researcher, and powder of natural shell has nanoporous structure, can adsorb
Formaldehyde, ammonia, benzene to dissociate in air etc., and the chitin contained in the life oyster shell whiting without calcining can decompose these and have
Poisonous gas, TVOC in control room；Oyster shell whiting is to a variety of thin including Escherichia coli, salmonella and staphylococcus aureus
Bacterium has extremely strong killing and inhibitory action, can prevent coating from going mouldy to come off；In addition, can be with using the microcellular structure of oyster shell whiting,
It can adsorb and discharge moisture, so as to fulfill the adjusting of indoor air humidity；But the oyster shell whiting without calcining does not have caking property,
Can only be as the filler of coating, and the oyster shell whiting through calcining remains with microcellular structure, by being modified to it, can make it have drop
Toxic gas, the negative particle function of release are solved, and it is well dispersed, and cementability is strong, lives or does in household, classroom, office etc.
The furnishing fields of public indoor wall have huge application potential.
The content of the invention
The present invention provides a kind of preparation method and applications of multifunctional nano shell powder paint, the multifunctional nano shellfish
Shell powder coating includes following parts by weight of component：Modified 100 parts of oyster shell whiting, re-dispersible glue powder 15-25, raw 30-40 parts of oyster shell whiting,

The preparation method of wherein modified oyster shell whiting is：
A. discarded oyster shell whiting is put into 8% sodium hydroxide solution and impregnated for 24 hours after water cleans up, then it is multiple with distilled water
Cleaning, is placed in 80 DEG C of drying boxes, is dried in vacuo 12h, is crushed to grain size less than 100 mesh with multifunctional crusher, then uses ball milling
Machine is ground to average grain diameter as 500nm, spare；
B. add in absolute ethyl alcohol in a kettle, open stirring, temperature is controlled at 20-30 DEG C, be added dropwise successively butyl titanate and
Glacial acetic acid continues to stir 30min after being added dropwise to complete, and starts that nital is added dropwise, waits to be added dropwise, and continues to stir 2h, obtain
To TiO 2 sol, life oyster shell whiting and appropriate dispersant prepared by appropriate step a are added in into TiO 2 sol, is acutely stirred
It after mixing 3h, is washed for several times with absolute ethyl alcohol, 80 DEG C of vacuum drying 6h, 850 DEG C of calcining 10h obtain titanium dichloride load oyster shell whiting；
C. weigh oyster shell whiting prepared by appropriate step b, add in distilled water and dispersant, ultrasonic disperse 4h, warming-in-water to 70 DEG C,
Appropriate odium stearate is added in, after being stirred to react 12h, is cooled to room temperature, is filtered with absolute ethyl alcohol, distills water washing for several times, vacuum
It is dry, average grain diameter is ground to as 500nm, obtains the modified oyster shell whiting.
Re-dispersible glue powder is：One or both of ethylene-vinyl acetate copolymer, acrylic copolymer, raw shell
Powder is the oyster shell whiting that average grain diameter prepared by step a is 500nm, and the average grain diameter of tourmaline powder is 500nm, pigment is iron oxide yellow,
One kind in phthalocyanine green, toluidines purple, carbon black, toluidine red, antifoaming agent are powdered Polyether Modified Polysiloxanes Defoaming Agent SA-2.
The preparation method of shell part coating is：In homogenizer, sequentially add formula ratio and be modified oyster shell whiting, can divide again
Rubber powder, raw oyster shell whiting, tourmaline powder, antifoaming agent are dissipated, 4h is to get finely dispersed multifunctional nano shell powder paint for stirring；Institute
State shell powder paint in use, with water in mass ratio 2:1 be sufficiently mixed uniformly can brushing metope.
Compared with prior art, the gain effect acquired by the present invention has：1. matched somebody with somebody by raw oyster shell whiting and modified oyster shell whiting
It closes and uses, chitin and titanium dioxide in modified oyster shell whiting are used cooperatively in raw oyster shell whiting, can be significantly improved its degradation and be inhaled
The ability of attached toxic gas；2. oyster shell whiting is modified by using stearic acid sodium, significantly improve oyster shell whiting and other fillers and is helped
The compatibility of agent improves its dispersiveness in water, avoids the appearance reunited, and improves the uniformity of coating；3. coating of the present invention
To be powdered, production and processing is convenient, and especially transport carrying cost is cheap, and use is easy for construction, the front in home office
Field of constructional ornament application potential is huge.
The above-mentioned of the application and other features, aspect and advantage is more readily understood with reference to following detailed description.
