Background technology
Since Aschkinass (A Sha Maas) in 1902 and Caspan (Caspar) certainly negative aeroion have biological meaning, Soviet Union scholar in 1903 has delivered and has utilized negative aeroion to eliminate since the paper of germ, particularly various countries have carried out a large amount of experimental studies in recent years, have further affirmed the value of negative aeroion.
Raising along with people's living standard, to living environment to beautify requirement also more and more higher, especially the decoration of household is more and more luxurious, people have been enclosed in the world of a finishing material, and these finishing material are discharging various deleterious gases, have caused the pollution of living environment.The modern environment Hygiene investigation studies show that, conventional design and finishing in city and residential district planning, make that the active crowd has produced a series of subjective symptomss in buildings, be called " sick Building syndrome " (sick buildingsyndrome, SBS), also claim " ill buildings syndrome ".External in recent years relevant expert proposes, the finishing of conventional design can not guarantee to have in the space air negative ion of sufficient amount, even workplace at ultra-clean, though constant temperature, constant humidity, cleaning, enough ventilation volumes are also arranged, but people still usually feel to feel dizzy, tired, the uncomfortable in chest obstruction of the circulation of vital energy easily, has no comfort, this is owing to lack due to the negative aeroion in the room, reason is to contain materials such as formaldehyde, toluene, sulfide in the common finishing material, and HUMAN HEALTH is caused great harm.
At present, room and office space mainly adopt air negative ion generator to improve negative ion concentration in the room air, improve IAQ (indoor air quality).But the negative oxygen ion burst size that anion generator produces is very little, can only be distributed in anion generator around, be difficult to be diffused into whole room, power is lower, the effect of purifying air is undesirable.And air negative ion generator also can produce some harmful gases such as ozone and oxynitride when producing negative ion, and security is difficult to guarantee.
Summary of the invention
The purpose of this invention is to provide a kind of paint additive that contains tourmalinite, it is added in the coating, brushing is on the wall of room, on the top ceiling, not only can beautify the room, can also bring into play the function of tourmalinite, discharge enough negative aeroions to the interior space, improve Air quality, environment purification.
Paint additive of the present invention is made up of tourmaline powder, anatase thpe white powder, nano-titanium oxide, nano zine oxide, forms through pulverizing, grind, stirring, and the weight percent of each composition is:
Tourmaline powder 50~65%
Anatase thpe white powder 30~45%
Nano titanium oxide 0.5~2%
Nano zine oxide 0.5~3%
Wherein, the tourmaline powder granularity of use is 2~5 μ m, and the granularity of anatase thpe white powder is 45~50 μ m, and the granularity of nano titanium oxide and nano zine oxide is 0.25~0.35 μ m.
The concrete preparation method who contains the tourmalinite paint additive is, tourmaline powder is broken into the fine powder of 2~5 μ m, anatase thpe white powder be ground into 45~50 μ m fine powder, mix by the above-mentioned raw materials proportioning with the nano titanium oxide and the nano zine oxide of 0.25~0.35 μ m particle diameter, stir 20~30min, make it even, packing is made paint additive.
Tourmalinite is a kind of natural mineral crystal, it is to be aluminium, sodium, iron, the magnesium of feature, the ring texture silicate ore of lithium with the boracic, its microtexture is very special, two end points along crystallographic axis Z direction have been assembled positive and negative opposite electric charge, form the electric field of two electrodes, so it has piezoelectric effect and thermoelectric effect.Among the present invention, the tourmalinite crystal is processed into the ultra-fine tourmaline powder that diameter is 2~5 μ m, its characteristic not only can not weaken or disappear, and can strengthen because of increasing of electrode on the contrary.The ultra-fine tourmaline powder is joined in the coating, numerous tourmaline particles is that carrier adheres on wall, the top ceiling equably with coating, when the variation of the friction that is subjected to air flowing, room temp, these tourmaline powders contact with indoor steam, can discharge negative aeroion, purifying the air of a room arranged, improve Air quality, eliminate the effect of peculiar smell, can also eliminate the harmful chemical that contains in the coating.
The particulate that characteristics of the present invention also are embodied in tourmaline powder is more little, and big more with the contact area of air, the effect of tourmalinite can be fully utilized, and obtains enough negative aeroions; Tourmaline powder adheres on indoor whole wall, the top ceiling equably, and negative aeroion also can be distributed in the whole room equably.
Oxyradical is a kind of extremely unsettled material, too much radical pair body has suitable harm, it can destroy protein, make people's aging, infringement nucleic acid, destroys carbohydrate, cytolemma, quickens arteriosclerosis, suppresses immunologic function, causes the generation of cancer.The peripheral electron of oxyradical lacks than normal state, and the peripheral electron of negative ion is more than normal state, the additional electronics of negative ion just can be supplied with the oxyradical that lacks electronics, makes oxyradical obtain the electronics that it lacked and is neutralized, and oxyradical is not had poison.
Negative aeroion can also make the body fluid of human body be weakly alkaline.The constant acid base equilibrium is the essential condition that keeps the cell eubolism in the body fluid, and pH value of blood is constant in 7.35~7.45 these scopes, and average out to 7.4 is weakly alkaline.Because modern people's living standard generally improves, the quantity of food meat increases greatly, adds the pollution of air, water, food, causes people's body fluid oxytropism conversion gradually.Negative oxygen ion can be supplied with the electronegative electronics of hydrogen ion, and the oxidising process that provides electronics to suppress free radical, to reduce hydrionic concentration in the body fluid, makes body fluid be weakly alkaline.
Negative aeroion also can make Air quality improve.Negative ion can reduce from the active oxygen of generations such as atmospheric pollution substance, oxynitrides, cigarette; Microbial suspension pollutents such as the waste gas that negative ion can be discharged with dust in the atmosphere, factory and automobile, virus, bacterium etc. have the ion neutralization of positive charge mostly, and sedimentation behind no electric charge is well purified air; Negative ion can react effectively with attached to the odor source molecule on wall, the top ceiling, and its foul smell is no longer produced; Negative ion can eliminate because irritant gass such as the benzene that the various finishing material of interior decoration evaporate, formaldehyde, ketone, ammonia, the acid smell of leftovers, cigarette peculiar smell etc. in the daily life.
The anatase thpe white powder that uses among the present invention has good optical property, purity height, good, the strong covering power of whiteness, and be easy to disperse.Be applicable to water-based and the air-dry wall of solvent-borne type air, top ceiling coating, also can be applied directly to the top coat of ornamental cloth curtain.
Nano titanium oxide is tiny because of particle, specific surface area has the not available special effects of conventional material greatly, and photocatalysis and function such as ultraviolet shielded.Nano titanium oxide itself is a chemically inert material, under usual conditions not with soda acid generation chemical reaction, with human body good consistency is arranged, nontoxic to human body.UV-light and part visible light in the nano titanium oxide energy strong absorption sunlight, go out the intensive photon at its surface excitation, the about 3600K of the photon energy on nano titanium oxide surface, the temperature that almost is equivalent to sun surface, so high energy can make oxidized water and the carbonic acid gas of being decomposed into of organism, and the sulphur that organism initially contains, phosphorus and nitrogen-atoms etc. are separately converted to SO
