Abstract
The invention provides an energy-saving and antibacterial nano ceramic coating. The coating comprises the following components in percentage by mass: 40-50% of silica sol, 35-45% of silane coupling agents, 5-10% of antibacterial nano particles, 1-2% of nonionic surfactants, 1-2% of waterborne leveling agents and 5-10% of hard fillers. Hydrosol of nano silica serves as a carrier and the added silane coupling agents serve as intermediaries, so that agglomeration between nano Ag and nano TiO2 is reduced effectively; the nano TiO2 with a sterilizing effect is combined with the nano Ag with a sterilizing effect, so that an excellent sterilizing effect is achieved; and meanwhile, organic materials or toxic components are not added in a preparation process of the coating, components which have potential threats on health do not exist either, and the coating conforms to provisions of WEEE, RoHs, FDA and the like on requirements of environmental protection.
Description
Technical field
The present invention relates to a kind of energy-conservation antimicrobial nano ceramic coating, be mainly used on the container containing of field of food, heating electrical appliance, there is effect that is energy-conservation, antibacterial bacteriostatic.
Background technology
Along with the development of science and technology, growth in the living standard, people more and more pay close attention to healthy and safe mode of life.Concrete, in life, there are the various product needed antibacterial efficacies contacted with human body, especially contact very close articles for use in people's daily life, as the container etc. for packing foods, if not through sterilizing, some common bacteriums are very easy to import human body into, cause disease to infect.
In order to the breeding of anti-bacteria, various antibiotic paint arises at the historic moment.The antiseptic-germicide used in coating mainly contains natural antibacterial agent, inorganic antiseptic and organic antibacterial agent.From the over-all properties of these three kinds of antiseptic-germicides, inorganic nano antiseptic because of its particle diameter little and the excellent adsorption of bacterium is used extensively.In addition, be applied to by nanoparticle in coating, its special magnetic, optical, electrical performance and high-strength, high-ductility, performance that is wear-resisting, excellent stability are very suitable as antibiotic paint.
Inorganic nano antiseptic conventional now mainly contains nanometer silver and nano-TiO
2two kinds.Nano titanium oxide can remove bacterium, purify air, because it is under the condition of light or water, electronics in its valence band is excited to conduction band, valence band produces hole, unbound electron-hole is to making oxygen and water activation, produce active oxygen and the hydroxyl radical free radical with very high reaction activity, there is very strong Degradation to the obnoxious flavour (oxynitride, sulfurous gas, formaldehyde, benzene, ammonia, acetone etc.) in air and bacterium, thus give the good germ resistance of coating and the performance that purifies air; Nano titanium oxide only just has germ resistance and the performance that purifies air under the condition of light or water, which has limited its application in dark area or Arid Area.The Antibacterial Mechanism of nanometer silver is mainly reacted by the phospholipid of silver ions and bacterium, plays sterilization effect, is affected by the external environment very little, but nanometer silver can continuous stripping make antibacterial effect decline and easily reunion, oxidizable, easy to change.
Nanometer silver and nano titanium oxide are combined, can further improve the germ resistance of coating.On the one hand, nanometer silver exists as impurity, can strengthen the photocatalysis performance of nano titanium oxide; On the other hand, nanometer silver slowly releases Ag
+, the activity of protista organized enzyme can be destroyed, there is very strong bactericidal properties, and not by the impact of ambient conditions (Guang Heshui), but the difference of performance between nanometer Ag and nano titanium oxide, the two unsatisfactory in conjunction with effect.
Disclose a kind of nano titanium oxide/nanometer silver coating and preparation method thereof in CN1583901A: by nano titanium oxide dispersion and Nano silver solution blended, add membrane-forming agent, wetting dispersing agent, flow agent and defoamer, prepare a kind of nano paint comprising nano titanium oxide and nanometer money kind nanoparticle, this coating solves the feature of existing coating contamination resistance difference.But adopt in this blended prepared nano paint, nanometer silver is very easily reunited, and affects its durable antibiotic performance.In addition, two kinds of nanoparticles easily mix uneven, easily cause single to gather more, reduce anti-microbial activity, can not make full use of two advantage of planting different mechanism antiseptic-germicide.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of energy-conservation antimicrobial nano ceramic coating, by with the water-sol of nano silicon for carrier, and being vehicle by adding silane coupling agent, effectively reducing nanometer Ag and nano-TiO
2between reunion, will the nano-TiO of sterilization effect be had
2combine with nanometer Ag, achieve excellent sterilization effect.
In order to realize technical purpose of the present invention, the present invention takes following technical scheme.

Preferably, the particle diameter of described nano silicon is 20-100 nanometer.
Preferably, described silane coupling agent is methyl, ethyl, phenyl or vinyltriethoxysilane.
Preferably, described antimicrobial nano particle is nano Ag particles or nano-TiO
2one or both in particle mix with arbitrary proportion.
Preferably, the particle diameter of described antimicrobial nano particle is 20-40 nanometer.
Preferably, by mass, described nano-TiO
2composition is the Anatase of 60% and the Rutile Type of 40% mutually.
Preferably, described flow agent is silicone based or polyacrylic flow agent.
Preferably, hard filler described in described hard filler is the one in aluminum oxide, aluminium hydroxide, pure aluminium silicate, kaolin, talcum or silicon oxide, increases the wear resistance of coating.
The invention provides a kind of energy-conservation antimicrobial nano ceramic coating, by with the water-sol of nano silicon for carrier, and being vehicle by adding silane coupling agent, effectively reducing nanometer Ag and nano-TiO
2between reunion, by adding nonionogenic tenside, utilize its high stability, be not subject to the feature of strong electrolyte impact, further mitigate the reunion between nano Ag particles, enable nano Ag particles, nano-titania particle dispersed, be adsorbed in the water-sol of nano silicon, significantly improve its antibacterial effect.By adding silicone based or polyacrylic flow agent, effectively reducing coating surface tension force, making coating in film process, form smooth, smooth, a uniform film.
