Embodiment 1

[0040] 1) Take 10 parts of urea peroxide or thiourea and add it to 85 parts of water, fully dissolve;

[0041] 2) Then add, 2 parts of magnesium chloride, 1 part of bromide (a mixture of sodium bromide, barium bromide, and calcium bromide in a weight ratio of 1:1:1), 1 part of titanium dioxide, and 1 part of strong oxygen amino (manganese oxide, oxide zirconium weight ratio 1:1 mixture), 1 part of water-soluble azone. Stir well to dissolve.

[0042] 3) After aging for 2 hours, it can be used immediately.

Embodiment 2

[0044] 1) Take 8 parts of urea peroxide or thiourea and add them to 85 parts of water to fully dissolve;

[0045] 2) Then add 1 part of calcium chloride, 1 part of bromide (a mixture of sodium bromide and barium bromide with a weight ratio of 1:1), 1 part of titanium dioxide and 1 part of strong metal oxide (manganese oxide), 1 part of water-soluble Azone. Stir well to dissolve.

[0046] 3) After aging for 2 hours, it can be used.

Embodiment 3

[0048] 1) Take 6 parts of urea peroxide or thiourea and add it to 85 parts of water to fully dissolve;

[0049] 2) Then add 1 part of magnesium chloride, 1 part of bromide (calcium bromide), 1 part of titanium dioxide, 1 part of strong metal oxide (zirconia), and 1 part of water-soluble azone. Stir well to dissolve.

[0050] 3) After aging for 2 hours, it can be used.

[0051] The finished products processed by the above methods have a very good effect of degrading and eliminating formaldehyde when spraying materials with formaldehyde emission. The average elimination rate is above 96%, which is the most ideal formaldehyde removal product at present.

Abstract

The invention relates to a formaldehyde scavenger and a preparation method thereof. The formaldehyde scavenger mainly comprises the following components in parts by weight: 6-10 parts of urea peroxide or sulfourea, 1-2 parts of alkaline earth metal chloride, 1 part of bromide, 1 part of titanium dioxide and 1 part of strong metal oxide; or the formaldehyde scavenger further comprises 1 part of water-soluble azone and 80-85 parts of water. Compared with existing formaldehyde scavengers, the formaldehyde scavenger provided by the invention is a broad-spectrum constant capture catalyst with simple manufacturing process, high formaldehyde removing efficiency and very good market application prospect.

Description

technical field [0001] The invention relates to a decoration pollution remover, in particular to a formaldehyde scavenger. Background technique [0002] Formaldehyde is a colorless gas with a strong pungent odor, easily soluble in water, alcohol and ether. Formaldehyde is gaseous at room temperature, usually in the form of aqueous solution, easily soluble in water and ethanol. [0003] Formaldehyde is a protoplasm poison, which can be combined with protein. After inhaling high-concentration formaldehyde, there will be severe irritation of the respiratory tract, edema, eye stinging, headache, and bronchial asthma. Frequent inhalation of a small amount of formaldehyde can cause chronic poisoning and mucous membranes. Congestion, skin irritation, allergic dermatitis, nail bed fingertip pain and other symptoms. Long-term inhalation by pregnant women may lead to deformity and even death of newborn babies. Long-term inhalation by men may lead to sperm deformity, death, and decrea...
