Embodiment 1

[0032] Dissolve 5g of water-soluble chitosan quaternary ammonium salt in 910g of pure water, then add 50g of ethylene urea to the above mixture and stir evenly, and finally add 10g of eucalyptus oil, 5g of azone, and 20g of nano-anion powder in turn, and fully stir That is, a double-effect catalyst for removing aldehyde and deodorizing is obtained, which is used for removing low-pollution formaldehyde, and the removal rate of formaldehyde reaches over 90% within 24 hours.

[0033] For specific test results, see the attached Figure 1-3 .

Embodiment 2

[0035] Dissolve 10g of water-soluble chitosan quaternary ammonium salt in 860g of pure water, then add 80g of ethylene urea to the above mixture and stir evenly, and finally add 20g of eucalyptus oil, 10g of azone, and 20g of nano-anion powder in turn, and fully stir That is, a double-effect catalyst for removing aldehyde and deodorizing is obtained, which is used for removing low-pollution formaldehyde, and the removal rate of formaldehyde reaches over 90% within 24 hours.

Embodiment 3

[0037] Dissolve 8g of water-soluble chitosan quaternary ammonium salt in 854g of pure water, then add 95g of ethylene urea to the above mixture and stir evenly, and finally add 15g of eucalyptus oil, 8g of azone, and 20g of nano-anion powder in turn, and fully stir That is, a double-effect catalyst for removing aldehyde and deodorizing is obtained, which is used for removing low-pollution formaldehyde, and the removal rate of formaldehyde reaches over 90% within 24 hours.

Abstract

The invention discloses a formaldehyde-removal odor-removal double effect catalyst. The catalyst comprises, by weight, 5-10% of ethylene urea, 0.5-1% of chitosan quaternary ammonium salt, 1-2% of eucalyptus oil, 0.5-1% of azone, 2% of nanometer negative ion powder and the balance water. The formaldehyde-removal odor-removal double effect catalyst solves the problem that the traditional single ethylene urea hydrosolvent has good adhesion, a fast volatilization rate, short action time and a high cost.

Description

technical field [0001] The invention relates to the field of substances used for removing formaldehyde, benzene and TVOC harmful gases produced by interior decoration and wood-based panels, in particular to a double-effect catalyst for removing aldehydes and purifying odors. Background technique [0002] After the industry's inspection of the newly decorated indoor environment and wood-based panel furniture, the formaldehyde in a large number of newly decorated rooms generally exceeds the standard by about 80%. On the one hand, the industry has different standards for formaldehyde content and indoor air quality in wood-based panel furniture. Extensive use of wood-based panels and wood-based panel furniture for decoration has caused formaldehyde to exceed the standard in a certain space. Formaldehyde has become the number one hazard of air pollution in people's homes. Most of the known formaldehyde scavenging agents have the disadvantages of corroding metal trim parts and rem...
