Abstract

The invention provides a nanometer platinum net material, a preparing method of the nanometer platinum net material and an air purifier. The nanometer platinum net material comprises a net body and nanometer platinum particles which are attached to the net body and form a nanometer platinum particle layer on the outer side of the net body. According to the technical scheme, the nanometer platinum particle layer is formed on the outer side of the nanometer platinum net material, and nanometer platinum has the effect of absorbing energy of ultraviolet light; when ultraviolet light irradiates nanometer platinum, the wavelength can be increased, and meanwhile a certain amount of heat can be generated, in other words, ultraviolet light can be changed into visible light harmless to the human body. The nanometer platinum net material can change ultraviolet light into visible light in the same way, and thus the effect of isolating or shielding ultraviolet light can be achieved; when the nanometer platinum net material is applied to the air purifier, the effect of isolating disinfecting ultraviolet lamps in the air purifier can be achieved, leaking of ultraviolet light can be avoided, and thus human health can be protected.

Example Embodiment

[0046] Example 1:
[0047] The first step is to dissolve 95.0% pure platinum in aqua regia to obtain chloroplatinic acid (H2PtCl6·6H2O, red to brown-red solid), dissolve solid chloroplatinic acid in water, and then add 2.0% number average to the net chloroplatinic acid aqueous solution Polyvinyl alcohol with a molecular weight of 5000, stir for 10 minutes and then stand by; the second step is to soak the glass fiber mesh with a thickness of 1.0mm in the water in the stainless steel reactor, and then make the water temperature and pressure exceed the critical point (critical temperature T = 374 ℃, critical pressure P=22.1MPa) is supercritical water. Supercritical water has very good oxidizing properties. It can oxidize/etch many chemical functional groups and microscopic protrusions on the surface of glass fiber (this makes the first The solution is easier to "bond" on the surface of the glass fiber mesh); in the third step, the treated glass fiber mesh is soaked in the solution of the first step for 30 minutes, and then taken out to dry naturally. After drying, the glass fiber is again The net is soaked in the solution of the first step, and this is repeated 4 times; in the fourth step, the soaked glass fiber net is irradiated in front of a short-wave ultraviolet (wavelength 200nm to 280nm) lamp with a power of not less than 30W for 10 minutes. The nano platinum mesh is obtained.
[0048] The average size of platinum nano particles on the surface of the glass fiber mesh was measured by a high-resolution scanning electron microscope as 45nm; the American standard (ASTM C633-2013 thermal spray coating adhesion or bond strength test method) was used to test the surface of the glass fiber mesh and the platinum nano layer and The strength of the interface between the glass fibers is significantly higher than the strength of the glass fibers themselves, which indicates that a good interface bond between the nano-platinum layer and the glass fibers is formed; the national ultraviolet detection standard (GB/T 13971-1992 ultraviolet gas analyzer technical conditions) ) Detect that the radiation leakage of ultraviolet radiation outside the platinum nanometer net that wraps the ultraviolet lamp is 0, and the radiation intensity is 0.

[0049] Example 2:
[0050] The first step of the present invention is to dissolve platinum with a purity of 96.0% in aqua regia to obtain chloroplatinic acid (H2PtCl6·6H2O, red to brown-red solid), dissolve solid chloroplatinic acid in water, and then add 3.0 to the chloroplatinic acid aqueous solution. % Polyvinyl alcohol with a number average molecular weight of 5000, stir for 15 minutes and then stand by; the second step is to soak the 2.0-thick glass fiber mesh in the water in the stainless steel reactor, and then make the water temperature and pressure exceed the critical point (critical temperature T =374℃, critical pressure P=22.1MPa), supercritical water will become supercritical water. Supercritical water has very good oxidizing properties and can oxidize/etch many chemical functional groups and microscopic protrusions on the surface of glass fiber (which makes The solution in the first step is easier to "bond" on the surface of the glass fiber mesh); in the third step, the treated glass fiber mesh is soaked in the solution of the first step for 40 minutes, and then taken out to dry naturally. After drying, the The glass fiber mesh is soaked in the solution of the first step and repeated 5 times; the fourth step, the soaked glass fiber mesh is irradiated in front of a short-wave ultraviolet (wavelength 200nm to 280nm) lamp with a power of not less than 30W for 15 minutes After that, the nano-platinum mesh material is obtained.
[0051] The average size of platinum nano particles on the surface of the glass fiber mesh was tested with a high-resolution scanning electron microscope to be 52nm; the American standard (ASTM C633-2013 thermal spray coating adhesion or bond strength test method) was used to test the surface of the glass fiber mesh and the platinum nano layer and The strength of the interface between the glass fibers is significantly higher than the strength of the glass fibers themselves, which indicates that a good interface bond between the nano-platinum layer and the glass fibers is formed; the national ultraviolet detection standard (GB/T 13971-1992 ultraviolet gas analyzer technical conditions) ) Detect that the radiation leakage of ultraviolet radiation outside the platinum nanometer net that wraps the ultraviolet lamp is 0, and the radiation intensity is 0.

Supercritical water has very good oxidizing properties and can oxidize/etch many chemical functional groups and microscopic protrusions on the surface of glass fiber (this Make it easier for the solution in the first step to "bond" on the surface of the glass fiber mesh); in the third step, the treated glass fiber mesh is soaked in the solution of the first step for 45 minutes, and then taken out to dry naturally, after drying, again Soak the glass fiber mesh in the solution of the first step and repeat the process 6 times; in the fourth step, place the soaked glass fiber mesh in front of a short-wave ultraviolet (wavelength 200nm to 280nm) lamp with a power of not less than 30W for 20 Minutes later, the nano platinum mesh is obtained.
