Problems solved by technology

[0003] The formaldehyde scavengers that have been reported have many types of formaldehyde capture agents, such as the published Chinese patents CN1463753A, CN1104657A and CN1526470A, which have single functions, lack comprehensive removal of indoor pollutants, and can only be single decomposition or adsorption formaldehyde, and It does not have a bactericidal effect, and what people often come into contact with in the living environment is not only the pollution of volatile substances such as formaldehyde, benzene, ammonia, TVOC, etc., but also has many bacteria that affect people's normal life

Embodiment 1

[0026] Weigh 97 kg of distilled water, add 0.2 kg of 50000ppm nano-silver colloid, stir for 5 minutes, then add 0.8 kg of triethanolamine, 0.2 kg of sodium metabisulfite, 0.2 kg of disodium edetate, 1 kg of ammonium chloride, and 0.6 kg of glucose , stirred for 20 minutes, and filtered to obtain a slightly light yellow and transparent nano silver-based formaldehyde elimination solution.

[0027] The nano-silver-based formaldehyde elimination solution prepared in Example 1 was used to eliminate formaldehyde and bacteria on the surface of furniture and artificial boards. After testing by the Indoor Environment Monitoring Center of China Decoration Association, the formaldehyde removal rate of the nano-silver-based formaldehyde elimination solution was 95.1%. %; tested by the Shanghai Center for Disease Control and Prevention, the nano-silver-based formaldehyde elimination liquid has a bacteriostatic rate of 93.7% to Escherichia coli and Staphylococcus aureus (ATCC6538).

Embodiment 2

[0029] Weigh 98 kg of distilled water, add 0.2 kg of 50000ppm nano-silver colloid, stir for 5 minutes, then add 0.3 kg of triethanolamine, 0.1 kg of sodium metabisulfite, 0.1 kg of disodium edetate, 0.9 kg of ammonium chloride, and 0.4 kg of glucose , stirred for 20 minutes, and filtered to obtain a slightly light yellow and transparent nano silver-based formaldehyde elimination solution.

[0030] The nano-silver-based formaldehyde elimination solution prepared in Example 2 was used to eliminate formaldehyde and bacteria on the surface of furniture and artificial boards. After testing by the Indoor Environment Monitoring Center of China Decoration Association, the formaldehyde removal rate of the nano-silver-based formaldehyde elimination solution was 93.5%. %; tested by Shanghai Center for Disease Control and Prevention, the nano-silver-based formaldehyde elimination liquid has a bacteriostatic rate of 92.3% to Escherichia coli and Staphylococcus aureus (ATCC6538).

Embodiment 3

[0032] Weigh 95 kg of distilled water, add 0.2 kg of 50000ppm nano-silver colloid, stir for 5 minutes, then add 1 kg of triethanolamine, 0.4 kg of sodium metabisulfite, 0.4 kg of disodium edetate, 2 kg of ammonium chloride, and 1 kg of glucose , stirred for 20 minutes, and filtered to obtain a nano-silver-based formaldehyde elimination solution containing a concentration of 100 ppm of nano-silver particles.

[0033] The nano-silver-based formaldehyde elimination solution prepared in Example 3 was used to eliminate formaldehyde and bacteria on the surface of furniture and artificial boards. After testing by the Indoor Environment Monitoring Center of China Decoration Association, the formaldehyde elimination rate of the nano-silver-based formaldehyde elimination solution was 96.0% %; tested by the Shanghai Center for Disease Control and Prevention, the nano-silver-based formaldehyde elimination liquid has a bacteriostatic rate of 94.4% to Escherichia coli and Staphylococcus aure...

Abstract

The invention relates to a nanometer silver formaldehyde eradicating-liquid, which is formed by triethanolamine, sodium sulfite, complexon, amchlor, amylaceum, water and water-soluble colloidal silver, wherein the average diameter of water-soluble colloidal silver is 1-100nm; said eradicating-liquid can quickly disinfect bacillus coli, etc, and reduce the free formaldehyde density under 0.08mg / m3, while the virus disinfection rate is above 90%. The invention also discloses a relative preparation.

Description

technical field [0001] The invention relates to a nano-silver-based formaldehyde elimination liquid capable of removing formaldehyde and antibacterial (bacteriostasis); the invention also relates to a preparation method of the nano-silver-based formaldehyde elimination liquid. Background technique [0002] With the enhancement of people's awareness of environmental protection, people's requirements for home decoration and living environment are getting higher and higher, and people generally pay attention to the quality of home indoor environment. Indoor air pollutants mainly affect indoor environmental quality, mainly organic toxic gases represented by formaldehyde, and bacteria, mainly Escherichia coli and Staphylococcus aureus, etc., which are often the direct cause of people's illnesses. [0003] The formaldehyde scavengers that have been reported have many types of formaldehyde capture agents, such as the published Chinese patents CN1463753A, CN1104657A and CN1526470A, ...
