example 1

[0018] Prepare 15% lysine hydrochloride solution, gradually add solid potassium hydroxide (about equimolar to lysine hydrochloride), stir while adding, when the pH of the solution is adjusted to 10.0, stop adding potassium hydroxide , this solution is the formaldehyde scavenger, and it is used separately. When using, spray, brush, and sprinkle in the room, walls, and furniture.

example 2

[0020] Take equimolar sodium bicarbonate and alanine and pack them separately. This is a two-phase packaged formaldehyde scavenger, which is used after dissolving sodium bicarbonate and alanine together in water. When using, spray, brush, and sprinkle in the room, walls, and furniture.

example 3

[0022] Prepare 20% alanine solution, add potassium bicarbonate equal molar to alanine, this is a formaldehyde scavenger, apply this formaldehyde scavenger on the non-woven fabric on the coating machine, the non-woven fabric after drying Cloth is formaldehyde removal cloth. When in use, the formaldehyde removal cloth can be spread in drawers, under the bed, under the mattress, under the sofa cushion, under the furniture, on the ground; paste and hang on the inner wall of the furniture, the outer wall of the furniture, the wall, the ceiling and other parts where formaldehyde is released.

Abstract

The present invention relates to a formaldehyde scavenger and is characterized in that the formaldehyde scavenger is the amino acid under the alkali condition. The formaldehyde scavenger can be carried by paper or cloth, and can also be a solid substance or a water solution. The formaldehyde scavenger is used to remove formaldehyde in the air. Moreover, the formaldehyde scavenger can be used to stop emission of formaldehyde from the furniture and decoration materials. The formaldehyde scavenger is odourless, intoxicant, involatile, safe and environment-friendly.

Description

Technical field: [0001] A formaldehyde scavenger is used to remove formaldehyde in the air, and can also be used to seal the release of formaldehyde from furniture and decoration materials. Background technique: [0002] Formaldehyde is a colorless and soluble irritating gas, which is harmful to health. It has attracted public attention in recent years. The state stipulates that the indoor formaldehyde content should not exceed 0.08mg / m 3 . Removing formaldehyde and controlling formaldehyde pollution are beneficial to the protection of people's health and have good social significance. [0003] There are many reagents for removing formaldehyde, patent application numbers 02113857.5, 88103032.5, 200410077942.6, 03143248.4, 03100568.3. The formaldehyde scavengers involved include bisulfite, sulfite, tea polyphenol, halide, nitrate, hydrazide, Amines, cyanamides, hydroxymethyl urea, adipic hydrazide, active methylene compounds, etc. However, bisulfite, sulfite, and tea polyph...
