Description
This invention relates to and is used for fitting-up in the daily life, the surface of sanitary equipment bathroom particularly, the artificial Monitoring and Controlling of a kind of convenience, have self-cleaning ability, the antibacterial ability of enhancing property and further reduce coatingsurface can making method.
Existing sanitary equipment bathroom and the self-cleaning antibacterial coating in fitting-up of relating to made the restriction of going up technical process and material proper property because of being subjected to it, often is difficult to possess the effect of self-cleaning antibacterial.Study carefully its middle cause, can be divided into following several:
1. as the clean base material of defending tool, in the majority with the porcelain and the glassiness usually.Advocate the demand psychology of health in order to cater to the human consumer, on manufacture craft, often on the adamantine layer of pottery or glass surface, directly adhere to materials such as one deck inorganic antiseptic, photocatalyst, attempt to reach the purpose of self-cleaning antibacterial.These are attached to the powder body material on the aspect, for can uniform distribution, influence outward appearance, and its particle diameter is very fine, and generally in nanometer scale, specific surface area is very big.And the material granule of these powder shaped all belongs to alkalimetal oxide, and when contacting and impose high temperature with the enamel material, the character of aspects such as the distinctive peculiar heat fusion joint of nano-scale particle, molecule bonding force, combining power and chemically reactive just embodies.Such as; fusing point is high; normality is that photocatalyst material titanium dioxide its heat fusion joint when nanomorphic of 1850 degrees centigrade then can reduce several times; because of its chemically reactive at nanomorphic extraordinary; very easily with the congruent melting of vitreous material silicate, the composition of silicate is complicated in addition, and mixing of titanium oxide arranged; make the overglaze vitrification point further reduce, form titaniferous silicate xln.Thereby broken the distinctive photocatalysis property of titanium oxide.If the increase material particle size does not make the characteristic of its nanomorphic highlight, then most probably because of can not vitreous influencing attractive in appearance and use;
2. the glaze treatment process that has with the inorganic antiseptic material granule of greater particle size, photocatalyst and enamel vitreous material consolute mutually, has a self-cleaning antibacterial function with bright.The prerequisite of inorganic antiseptic and its antibiotic mechanism of photocatalyst is that photocatalyst must contact with reactant (as media such as water, oxygen), makes medium discharge free ion, and destroys cell walls to reach germ-resistant purpose.After the enamel vitreous, even photocatalyst not by congruent melting, but is also coating the thicker vitrescence glaze of one deck, intercepted contacting of photocatalyst and medium, to such an extent as to can not be antibiotic;
3. because the energy gap of semiconductor photocatalysts such as titanium oxide greater than 3.0eV, can only absorb UV-light and near-ultraviolet light part in sunlight and the artificial light, so optical energy utilization efficiency is very low, less than 1%.If intensity of illumination a little less than, the perhaps dark environment of hinge, then photocatalyst can not its due katalysis of performance;
4. because of the big surface energy of pottery, glass inherent, and it is higher to cause its frictional coefficient.The common hole of its Surface Microstructure is more in addition, and is fine and close inadequately, and its acid-alkali-resistant degree of silicate top layer of vitreous state is lower, is easy to corrosion.This makes clean its top layer of tool of defending often adhere to dirt easily, is difficult to remove;
5. the clean clean surfaces antimicrobial coating of defending tool is finished with certain operation usually, and only 1 to 3 micron of its thickness can only disposablely use after completing, and can not artificially detect and intervene.Coating is is in use worn and torn, the perception of having no way of.
Therefore, the delicate self-cleaning antibacterial effect of photocatalyst all is subjected to domestic and international personage's concern and dispute always, and this also is the reason why China slowly fails to make relevant criterion.It the clean utilization of defending on the tool as antimicrobial coating more only be rest on conceptive.
Given this, the purpose of this invention is to provide a kind of degree of wear of feasible detection coating, controls its health state, and has self-cleaning ability, the antibacterial ability of enhancing property and further reduce coatingsurface and can make it be difficult for tarnishing and the corrosive making method.

The coating material of this invention, it is the rich fluoro-resin molecule that the form with the fluorine carbon bond exists, make full use of the characteristic of the electronegativity the highest (4.0) of fluorine atom, the ionic dissociation energy of the fluorine carbon bond behind the carburet is bigger than other chemical bond energy, bond length is the shortest, the fluorine carbon bond is difficult to fracture, and forms extraordinary densification and stable chemical combination form.Thereby its surface energy is very low, and frictional coefficient is very little;
In fluorocarbon, introduce nano-powders such as cerium oxide and hydrotalcite, can further reduce surface energy, make frictional coefficient littler.Because of the physical strength and the hardness of fluorocarbon are lower, cerium oxide and hydrotalcite can increase its hardness, simultaneously also can be in use, and because of friction causes the wearing and tearing on surface, cerium oxide can play polishing action at random.So can further reduce surface energy, effectively antifriction, thus the not adhesivity of fluorocarbon base material is strengthened.Cerium oxide and hydrotalcite also have special far red light chemical action and uv-absorbing screening capacity, thereby strengthen the self-cleaning function of coating;
In base material, introduce inorganic antiseptic, comprise inorganic silver system, copper system and rare-earth activated antiseptic-germicide.Every kind of its antibiotic mechanism of antiseptic-germicide, chemically reactive, control environment and adaptation bacterial classification thereof all have difference, and several persons associate with, and can give full play to and strengthen its broad-spectrum antimicrobial usefulness; Introduce photocatalyst particles such as zinc oxide, titanium oxide, can effectively utilize the UV-light and the near-ultraviolet light part of light, make the katalysis of photocatalyst generation, discharge free radical and sterilization contact medium;
Introducing has the negative ion releasing agent of pyroelectricity and piezoelectricity, its distinctive self poling performance, when temperature and pressure subtle change, just can cause the intercrystalline potential difference of powder, sustainable nonvolatil release negative ion and emitting far-infrared, and generation bioelectric current, to purify air antibiotic and sterilizing.Because facilities such as sanitary equipment bathroom are frequent with contacting of people, the negative ion releasing agent can utilize pyroelectricity and piezoelectricity fully, discharges negative ion and emitting far-infrared more, and human body is played a role in health care;
Introduce the photoluminescence agent, can strengthen the aesthetic degree of coating, also can artificially monitor homogeneity, the degree of wear, the user mode of coating simultaneously, also can contact the clean tool of defending easily at night, the high light of avoiding eyes to be turned on light suddenly stimulates.
Above-mentioned fluorocarbon for ease of coating, can be to be polymerized to resin, and its effective constituent fluorine element should be controlled between the 22-48%.
The introducing of above-mentioned nano-powder material, the per-cent that can increase and decrease various powders according to the use-pattern and the scope of coating.Such as, when emphasizing to monitor and to require the negative ion release rate higher, then can the appropriate per-cent that increases its quality.
The said structure of this invention has following advantage and effect:
1. the above-mentioned coating of enhancing property, make full use of the excellent chemical property of fluorocarbon, have than Ceramic glaze and the glassiness more acid-alkali-corrosive-resisting, ageing-resistant, erosion resistant, the low surface energy that it is excellent, make coating have very low frictional coefficient, can effectively prevent the viscous of dirt.
2. the introducing because of the nano-powder material of this coating all is to carry out at normal temperatures and pressures, with coated substrate any chemical reaction does not take place, thereby various material institute inherent performance is not cut down, this makes them present the one side of mutual supplement with each other's advantages more highlightedly, so that reaches high efficiency self-cleaning antibacterial usefulness.
3. its thickness of coating can artificially be controlled very easily, normally the 25-50 of Ceramic glaze photocatalyst layer thickness doubly, thereby its contained self-cleaning antibacterial factor also correspondingly is multiplied, and can fully guarantee permanent self-cleaning antibacterial usefulness.
4. the photoluminescence agent of coating introducing releasing energy behind the absorption luminous energy, can artificially be monitored its homogeneity, the degree of wear and user mode easily when dark, be beneficial to the wearing and tearing of timely repair coating, and make it to remain on good order and condition.
