Embodiment 1

[0026] Indoor air purifier among the present invention by following weight proportion:

[0027] Propylene Glycol 20%;

[0028] Hydrogenated Castor Oil 10%;

[0029] Modified Hydrogenated Castor Oil 10%;

[0030] denatured alcohol 5%;

[0031] Pinene 5%;

[0032] Menthane 5%;

[0033] Benzyl acetate 5%;

[0034] Lauryl Alcohol 5%;

[0035] Vanillin 5%;

[0036] Methylchloroisothiazolinone 0.05%;

[0037] Methylisothiazolinone 0.05%;

[0038] Fragrance 0.05%;

[0039] EDTA 0.05%;

[0040] Cocamidopropyl Betaine 0.05%;

[0041] The remaining 27.5% is distilled water.

[0042] The preparation method of the indoor air purifier is carried out as follows: hydrogenated castor oil, modified hydrogenated castor oil, propylene glycol and cocamidopropyl betaine are added to distilled water in sequence, heated to 90 ° C, and continuously stirred during the heating process. After keeping at 90°C for 1 hour, the temperature was lowered to 30°C to form a cooling liquid. Add dena...

Embodiment 2

[0044] Formaldehyde, hydrogen sulfide, ammonia removal rate experiment

[0045] After the finished product is made, the laboratory removal rate experiments of formaldehyde, hydrogen sulfide and ammonia are started respectively. Evenly volatilize the prepared standard solution to 5m 3 closed space. Prepare a nozzle with a certain flow rate and fix the air flow at 17.4m 3 / h, the flow rate is fixed at 1.5cm / s, and an appropriate amount of indoor air purifier is sprayed into the space. Close for 30 minutes after spraying. Samples are then taken and analyzed by testing instruments.

[0046] Table 1 The removal rate of formaldehyde, ammonia and hydrogen sulfide

[0047]

[0048] It can be drawn from Table 1 that the present invention can remove formaldehyde, ammonia, and hydrogen sulfide, and prove that the present invention has obvious treatment effects on formaldehyde, ammonia, and hydrogen sulfide.

[0049] The invention can make the removal rate of formaldehyde, ammoni...

Abstract

The invention discloses an indoor air purificant, which is rapid in response, thorough in management and low in cost, is capable of effectively removing harmful components in indoor air and simultaneously achieving sterilization and deodorization and a preparation method of the indoor air purificant. The preparation method of the indoor air purificant comprises the following steps: sequentially adding hydrogenated castor oil, modified hydrogenated castor oil, propylene glycol and cocamidopropyl betaine to distilled water, heating to 90 DEG C, continuously stirring in the heating process, cooling to 30 DEG C after keeping at 90 DEG C for an hour to form a cooling liquid; sequentially adding denatured alcohol, pinene, menthane, benzyl acetate, laurinol and vanillic aldehyde to the cooling liquid and stirring for 30min; finally sequentially adding methyl-isothiolinone, an essence and ethylenediamine tetraacetic acid, stirring until completely dissolving, standing for 12h and filtering to obtain a finished product. The indoor air purificant is long in duration and low in cost, and is capable of effectively removing the harmful components such as formaldehyde, hydrogen sulfide, an ammonia gas and xylene in the indoor air and achieving sterilization and deodorization. The indoor air purificant is directly sprayed to a to-be-managed area in use, and ventilation can carried out after spraying, so that the operation is simple and the indoor air purificant is very convenient and safe to use.

Description

technical field [0001] The invention discloses a preparation for eliminating harmful chemical substances and a preparation method thereof, in particular to an indoor air purifier and a preparation method thereof. Background technique [0002] Indoor environmental pollution has become the soot pollution (first generation pollution) brought by the industrial revolution in the 18th century and the photochemical smog pollution (second pollution) brought about by the development of petroleum and automobile industries in the 19th century. Since the middle of the 20th century, The third generation of indoor environmental pollution that continues in the 21st century. The World Health Organization has classified indoor pollution as one of the five major environmental factors that endanger public health. [0003] The indoor air pollution pollutants caused by decoration materials and building materials are mainly formaldehyde, benzene, xylene, etc., and hydrogen sulfide, ammonia, and ...
