Embodiment Construction

[0025] Add the acetic acid, urea, melamine, propylene glycol carbon alcohol fat, all of the emulsifier and half of the water in the above raw materials into the reactor. Heat to 80°C and react to PH=6.0, then add the remaining water, dicyandiamide, polyacrylamide, cool down to 20°C and add acetyl acetate, then the material can be stirred and discharged.

[0026] The appearance of this product is a colorless transparent liquid. PH is between 5.5-7.

[0027] Use this product to spray on the surface of the wood board. The amount of spraying is 20 grams per square meter, compared with the treatment of spraying materials on the market, and detected by the British f-400 formaldehyde detector. The test result is

[0028]

[0029] It can be seen from the example table that the duration and single effect of this sample to remove formaldehyde are relatively significant.

Abstract

An air purifying agent is used for eliminating formaldehyde and formic acid released from decorative materials in a new house, textiles and automobile exhaust. The air purifying agent, being prepared in a manner of co-polymerization and blending, is prepared from following materials, by weight, 40-60 parts of water, 8-9 parts of acetic acid, 20-30 parts of urea, 3-3.5 parts of an emulsifier, 7-8 parts of propylene glycol carbonate, 3-3.5 parts of melamine, 2-2.5 parts of dicyandiamide, 0.03-0.05 parts of polyacrylamide and 0.05-0.07 parts of ethyl acetoacetate. Substances generated through reaction between the air purifying agent and formaldehyde are all free of toxin so that the air purifying agent is free of generation of secondary pollution. The air purifying agent is high in formaldehyde eliminating speed, is good in effect. Formaldehyde eliminating ratios of the air purifying agent when being used for spraying wood boards and furniture can respectively reach more than 95% and more than 98%. The air purifying agent has a validity period being maintained for more than 30 days. The air purifying agent is simple in technology, is convenient to use and is low in cost.

Description

technical field [0001] The invention relates to a chemical formula for eliminating pollution and purifying air and a manufacturing method thereof, and is especially suitable for an air purifying agent used by people to eliminate formaldehyde gas emitted from new house decoration materials. Background technique [0002] At present, with the progress of society and the improvement of people's living standards, they pay great attention to the quality of housing. Formaldehyde is contained in decorative materials, formaldehyde is also contained in the manufacturing of textile industry, and even the exhaust gas of automobiles contains formaldehyde. People's daily life, and formaldehyde is a highly toxic gas, formaldehyde has a pungent smell, can be smelled at low concentrations, if people are exposed to low concentrations of formaldehyde for a long time, it will cause dizziness, headache, fatigue, sensory disturbance, Immunity is reduced, and drowsiness, respiratory dysfunction an...
