Problems solved by technology

The use of these means can clean the air to a certain extent, but these products cannot fundamentally purify the indoor environment, especially for "indoor air killers" such as bacteria and microorganisms with the ability to reproduce, these products all exist. Single efficacy, short duration, odor, noise, repeated consumption and secondary pollution, etc.

Embodiment 1

[0057] The preparation process of the nano multi-effect air cleaner of the present embodiment is as follows:

[0058] 1. Preparation of photocatalyst functional powder

[0059] Take 0.70kg of nano-scale titanium dioxide (20nm), 0.15kg of ferromagnesia tourmaline powder (500nm) and 0.15kg of rare earth activator lanthanum oxide (150nm), mix them, put them into an electric furnace, activate at 500°C for 1 hour, and cool with the furnace to obtain a photocatalyst functional powder. Nanoscale titanium dioxide adopts the commercially available product (ZY-Ti101 titanium dioxide micropowder) of Shanghai Zhanyang Nano Technology Co., Ltd. The ferromagnesian tourmaline powder is a commercially available product (ZY-H101) from Shanghai Zhanyang Nano Technology Co., Ltd.

[0060] 2. Preparation of nanometer multi-effect air purifier

[0061] Get photocatalyst functional powder 1kg, nano-scale silicon dioxide (50nm) 2kg, zinc oxide 0.1kg, propylene glycol 2kg, sodium hexametaphosphate...

Embodiment 2

[0067] The present embodiment is basically the same as Example 1, the difference being that the preparation process of the photocatalyst functional powder is: get nanoscale titanium dioxide (5nm) 6kg, iron tourmaline powder (400nm) 2kg and rare earth activator neodymium oxide (200nm) 1kg mix, put Put it into an electric furnace, activate it at 300°C for 2 hours, and cool down with the furnace to obtain photocatalyst functional powder.

[0068] The formula of nano multi-effect air purifier is: photocatalyst functional powder 5kg, nano-scale silicon dioxide (20nm) 8kg, silver oxide 0.15kg, propylene glycol 5kg, sodium hexametaphosphate 0.8kg, fatty alcohol sodium sulfate 5kg, polydimethyl Siloxane 4kg, deionized water 100kg.

[0069] Tested by authoritative departments such as Shanghai Environmental Protection Product Quality Supervision and Inspection Station:

[0070] The sterilization rate of the nanometer multi-effect air purifier of this embodiment reaches 96.5%; the forma...

Embodiment 3

[0072] The present embodiment is basically the same as Example 1, and the difference is that the preparation process of the photocatalyst functional powder is: get nanoscale titanium dioxide (15nm) 3.75kg, magnesium tourmaline powder (300nm) 1kg and rare earth activator praseodymium oxide (150nm) 1kg mix, Put it into an electric furnace, activate it at 450°C for 1.5h, and cool down with the furnace to obtain photocatalyst functional powder.

[0073] Photocatalyst functional powder 2kg, nano-scale silicon dioxide (30nm) 5kg, zinc oxide 0.3kg, propylene glycol 3kg, sodium hexametaphosphate 0.3kg, fatty alcohol polyoxyethylene ether 2kg, polydimethylsiloxane 0.5kg, deionized 70kg of water.

[0074] Tested by authoritative departments such as Shanghai Environmental Protection Product Quality Supervision and Inspection Station:

[0075] The sterilization rate of the nano multi-effect air purifier of this embodiment reaches 96%; the formaldehyde removal rate reaches 91.5%; the nega...

Abstract

The invention provides a multieffect nano air purificant including the following components by part by weight: 1 to 5 parts of photocatalyst functional powder, 2 to 10 parts of nanometer silica, 0.1 to 0.3 part of inorganic antibacterial powder, 2 to 5 parts of propanediol, 0.3 to 1 part of sodium hexametahposphate, 0.5 to 5 parts of surface active agent, 0.5 to 4 parts of dimethyl silicone polymer and 70 to 100 parts of deionized water. The nano multieffect air purificant of the invention solves the problem of wideband of nano concatemer, develops visible photocatalyst materials, and can give play to the effectiveness of the photocatalyst thereof under the long wave light near 600nm, namely, under the irradiation of an indoor fluorescent lamp, the photocatalyst can still have high activity.

Description

technical field [0001] The invention relates to a purifying agent, in particular to a nanometer multi-effect air purifying agent capable of removing formaldehyde, antibacterial and purifying air and its preparation method, especially applied to indoor craft decorations, furniture, curtains, toys and other products. Background technique [0002] The pollution of interior decoration materials and furniture is the main aspect causing indoor air pollution at present. Materials such as paint, plywood, shaving filler, interior wall paint, and plastic veneer all contain organic vapors such as formaldehyde, benzene, ethanol, and chloroform, all of which are quite carcinogenic. [0003] Investigations by specialized agencies in the United States and Japan have found that the indoor air pollution of many civil and commercial buildings is 2-5 times that of outdoor air pollution, and about 30% of the homes cause "new home syndrome" due to the use of harmful chemicals. The World Health ...
