Embodiment 1

[0018] The formaldehyde scavenger (Example 1) is composed of the following components in percentage by weight: polydecanediamine sebacate 5%; silicon dioxide 5%; ammonium chloride 1%; ammonium bisulfate 12%; urea 7%; Dicyandiamide 3%; hydroxyethylidene diphosphonic acid 5%; tea extract 3%; the balance is water.

[0019] The above components were stirred at a high speed, the stirring rate was 1200 rpm, and the stirring time was 60 minutes.

Embodiment 2

[0021] Formaldehyde scavenger (embodiment two) is made up of the component of following percentage by weight:

[0022] The formaldehyde scavenger (Example 2) is composed of the following components in percentage by weight: polydecanediamine sebacate 15%; silicon dioxide 1%; ammonium chloride 10%; ammonium bisulfate 4%; urea 1%; Melamine 8%; hydroxyethylidene diphosphonic acid 1%; honeysuckle extract 6%; the balance is water.

[0023] The above components were stirred at a high speed, the stirring rate was 14000 rpm, and the stirring time was 4 minutes.

Embodiment 3

[0025] Formaldehyde scavenger (embodiment three) is made up of the following components by weight percentage:

[0026] The formaldehyde scavenger (Example 3) is composed of the following components by weight percentage: polyaryl ether ketone 8%; silicon dioxide 3%; ammonium chloride 2%; ammonium bisulfate 7%; urea 3%; melamine 7% %; hydroxyethylidene diphosphonic acid 2%; peppermint extract 4%; the balance is water.

[0027] The above components were stirred at a high speed, the stirring rate was 8000 rpm, and the stirring time was 20 minutes.

Abstract

The invention discloses a formaldehyde scavenging agent. The formaldehyde scavenging agent is prepared from, by weight percent, 5%-15% of a high-molecular polymer, 1%-5% of silicon dioxide, 1%-10% of ammonium chloride, 4%-12% of ammonium bisulfate, 1%-7% of urea, 3%-8% of a cyanamide compound, 1%-5% of 1-hydroxyethylidene-1,1-diphosphonic acid, 3%-6% of plant extract and the balance water. The formaldehyde scavenging agent can scavenge formaldehyde thoroughly and protect human health and is low in cost.

Description

technical field [0001] The invention relates to a scavenger, in particular to a formaldehyde scavenger. Background technique [0002] The chemical formula of formaldehyde is HCHO, and the formula weight is 30.03. It is also called formaldehyde. It is a colorless gas with a special pungent smell, which is irritating to human eyes and nose. The relative density of the gas is 1.067 (air=1), the melting point is -92°C, and the boiling point is -19.5°C. Soluble in water and ethanol. The concentration of the aqueous solution can be up to 55%, usually 40%, called formaldehyde water, commonly known as formalin (formalin), is a colorless liquid with a pungent smell. Formaldehyde can be produced by dehydrogenation or oxidation of methanol under the catalysis of silver, copper and other metals, and can also be separated from hydrocarbon oxidation products. Used as pesticides and disinfectants, raw materials for making phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pen...
