Embodiment 1

[0025] Add 1167Kg of water into the 2000L enamel kettle and start stirring. Control the water temperature in the enamel kettle at 35°C±5°C. Add 1.2Kg sodium carbonate and 0.01Kg potassium hydroxide. Then, 0.01 Kg of hydroxyethyl cellulose and 100 Kg of 5,5-dimethylimidazolidinedione were added. After all the materials are dissolved, turn off the stirring, and after cooling down to 20°C, filter and discharge the material and fill it into the container.

Embodiment 2

[0027] Dissolve 1.0Kg of sodium carbonate and 0.02Kg of potassium hydroxide in 100Kg of water to make alkaline water. Add 1024Kg of ethanol into the 2000L enamel kettle and start stirring. Control the water temperature in the enamel kettle at 35°C±5°C. Then add 95Kg 5,5-dimethylimidazolidinedione, and add the alkaline water that has just been added after all the materials are dissolved. After all the materials are evenly mixed, turn off the stirring, cool down to 20°C, filter and discharge the material and fill it into the container.

Embodiment 3

[0029] Dissolve 1.4Kg sodium bicarbonate and 0.12Kg potassium hydroxide in 10Kg water to make alkaline water. Add 1280Kg of ethanol into the 2000L enamel kettle and start stirring. Control the water temperature in the enamel kettle at 35°C±5°C. Then add 87Kg 5,5-dimethylimidazolidinedione and 17Kg glycerol, and add the alkaline water that has just been added after all the materials are dissolved. After all the materials are evenly mixed, turn off the stirring, cool down to 20°C, filter and discharge the material and fill it into the container.

Abstract

The invention relates to a novel formaldehyde removing composite agent, with low cost, non secondary pollution and formaldehyde removing function. The inventive agent comprises at least one imidazolidinyl, at least one alkali compound and a solvent, wherein, the mass ratio between the imidazolidinyl and the alkali compound is 500:1-50:1, and the solvent mass is 0-99%. The inventive removing agent can be uniformly dissolved in general aquosity or oil paint, with excitation on the human body. And the inventive agent can be dissolved into solution to be added into the processed decorative material, or be plated on the face of object and around air, therefore, the free imidazolidinyl in air and material is reduced under 0.08mg / m2 as national standard.

Description

technical field [0001] The present invention relates to a novel formaldehyde removal agent composition. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, it is inevitable to buy a house and decorate it. Some wood-based panels used in the decoration process contain a certain amount of formaldehyde or its unstable compounds. Affected by the environment, these substances will eventually become formaldehyde gas and be released around us. The consequences of the ingestion of this gas by the body are well known. Therefore, it is of great practical significance to develop a new type of formaldehyde scavenger, which is harmless to the human body and has no secondary pollution. [0003] There are many reported formaldehyde removers, such as formaldehyde removers containing organic phenols, formaldehyde removers containing urea, and formaldehyde removers containing ammonium; but they have the following...
