Abstract
The utility model provides an antimicrobial enamel inner container used for a water heater. The antimicrobial enamel inner container used for the water heater comprises an inner container substrate and an enamel coating arranged on the surface of the inner container substrate, wherein the enamel coating comprises a bottom layer and a surface antimicrobial layer, and fumed silica powder bodies which absorb antimicrobial particles are arranged inside the surface antimicrobial layer. Preferably, the antimicrobial particles are composition of nanometer silver powder, nanometer copper powder, nanometer copper oxide particles and nanometer silver phosphate particles, and the diameter of the antimicrobial particles is nanoscale. According to the antimicrobial enamel inner container used for the water heater, silica powder bodies are mixed into the enamel coating, so that the antimicrobial particles gather on an enamel surface, and a small quantity of silver can achieve a good antimicrobial effect. Meanwhile, due to the fact that the added antimicrobial particles are mainly distributed on the enamel surface, constituents of an enamel substrate are basically unchanged, and mechanical property and corrosion-resisting property of the coating are maintained.
Description
Technical field
The utility model relates to the water-storage heater parts and makes the field, relates in particular to a kind of water heater antibacterial enamel inner bag.
Background technology
The kind of the electric heater that uses on the market and style are more and more, and function also is not quite similar.And present inner container of electric water heater is different according to material, generally can be divided three classes, and the one, add the coat of metal or plastic lining resin bed on the plain steel inwall; The 2nd, adopt stainless steel to be welded, the 3rd, apply enamel material and make enamel inner container on plain steel.Due to chlorion in water pure, the resistance to corrosion of front two kinds of water heater water courages is limited.Therefore, therefore enamel inner container is most widely used at present because having the advantages such as corrosion resistance and physical life be long.
Therefore in existing technology, enamel inner container has water storage at water heater water courage median year because water storage is more, often larger, as the long period need not, form stagnant water, be easy to breed bacteria.Unfavorable to user's health.Therefore be necessary to adopt antibacterial process, suppress the bacteria breed of long-time water storage.And water quality is a great problem of electric heater product technology as " stagnant water is said " that problem causes such as not using for a long time always.
At present, antibacterial enamel is the most promising electric heater water courage antibiotic method.Traditional the most general additive of antibacterial enamel is that the inorganic silver salt of employing is antiseptic, and the addition of silver salt need to be more than 2% usually; This will greatly increase production cost, be not easy to use on the inner container of electric water heater of high surface area, and the original properties of enamel layer itself is produced adverse influence.In addition, also having document to mention the employing complex antimicrobials, is mainly organic silver antiseptic and photocatalyst acting in conjunction.Be in the environment of a sealing due to water heater liner, so photocatalyst can not have sterilizing ability at this.Have document to propose to adopt the multilayer enamel coating, but multilayer enamel needs repeatedly sintering, technique is loaded down with trivial details, and power consumption is large, has also increased production cost.
In view of this, be necessary very to develop that a kind of low cost of manufacture, manufacturing process are simple, the New enamel water storage liner of good anti-bacterial effect.
Summary of the invention
For the deficiencies in the prior art, a purpose of the present utility model is to develop a kind of low cost of manufacture, little on the enamel property impact, and the water heater enamel inner container of good anti-bacterial effect.
For reaching above purpose, the utility model adopts following technical scheme.
A kind of water heater antibacterial enamel inner bag, comprise the inner bag matrix, and be arranged on the enamel coating of inner bag matrix surface, it is characterized in that, described enamel coating comprises bottom and antibacterial surface layer, is provided with the aerosil powder of adsorption antibacterial particle in this antibacterial surface layer.
As with improvement, the thickness of described bottom is between 0.1mm-0.2mm, and the thickness of described antibacterial surface layer is between 0.5mm-1mm.
As with improvement, described antibacterial surface layer comprises: particle size range is at the copper nanoparticle of 30nm-50nm, particle size range is at the nano-silver powder of 20nm-60nm, particle size range is at the aerosil powder of 150nm-250nm, particle size range is at the silver orthophosphate particle of 100nm-500nm, and particle size range is at the copper oxide particle of 100nm-600nm.
A kind of water heater antibacterial enamel inner bag that the utility model provides, by mix the aerosil powder in enamel coating, utilize the specific area of aerosil large, absorption affinity is strong and the antisolvent precipitation performance is adsorbed on the enamel coating surface with antimicrobial particle and forms the antibacterial surface layer, make the enrichment of enamel coating antibacterial surface particle, just obtain good antibacterial effect thereby reach with a small amount of silver particles, save the manufacturing cost of antibacterial enamel coating.Simultaneously, because the antimicrobial particle that adds mainly is enriched in the antibacterial surface layer, and bottom and the position composition variation of inner bag substrate contact are little, and be therefore little on mechanics and the decay resistance impact of enamel itself; Good with the adhesion of inner bag, decay resistance is strong.In addition, the diameter of particle of antimicrobial particle is convenient to overflow from coating at nanoscale, has good anti-microbial property, and Chinese People's Anti-Japanese Military and Political College enterobacteria and staphylococcus reach 90-99%.
Description of drawings
Figure 1 shows that the antibacterial enamel inner bag partial sectional view that the utility model provides.
The specific embodiment
For further setting forth essence of the present utility model, below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
Antibacterial enamel inner bag embodiment
As shown in Figure 1, a kind of water heater antibacterial enamel inner bag comprises inner bag matrix 1, and be arranged on the enamel coating 2 on inner bag matrix 1 surface, wherein, described enamel coating comprises bottom 3 and antibacterial surface layer 4, is provided with the aerosil powder 5 of adsorption antibacterial particle in this antibacterial surface layer 4.Preferably, described antimicrobial particle is nano-silver powder, copper nanoparticle, nano oxidized copper particle and nanometer silver orthophosphate particle; The thickness of described bottom is between 0.1mm-0.2mm, and the thickness of described antibacterial surface layer is between 0.5mm-1mm.
Wherein, composition and the particle diameter of described antimicrobial particle are as follows: the percentage by weight of copper nanoparticle is 0.5-3%, and particle size range is at 30nm-50nm; The percentage by weight of nano-silver powder is 0-0.4%, and particle size range is at 20nm-60nm; The percentage by weight of silver orthophosphate particle is 0.1-0.5%, and particle size range is at 100nm-500nm; The percentage by weight of copper oxide particle is 0-0.5%, and particle size range is at 100nm-600nm.Described aerosil powder percentage by weight is 0.2-0.8%, and particle size range is at 150nm-250nm.In other embodiments, described antibiotic ion is one or more in nano-silver powder, copper nanoparticle, nano oxidized copper particle and nanometer silver orthophosphate particle, is not limited to the present embodiment.
