Abstract

The invention discloses a formaldehyde decomposition liquid which comprises the following raw materials in parts by weight: 5-30 parts of sodium phytate, 2-15 parts of activated carbon, 2-20 parts of sodium sulfanilate, 0.2-5 parts of titanium dioxide, 1-15 parts of glucoside, 0.5-8 parts of ethylenediamine tetraacetic acid, 0.5-5 parts of ethyl acetate, 0.5-12 parts of dicyandiamide, 1-15 parts of carbohydrazide, 1-15 parts of sodium thiosulfate, 1-15 parts of glycerol and 50-120 parts of distilled water. A preparation method comprises the following steps: mixing the distilled water with titanium dioxide and the activated carbon, stirring, heating, adding other raw materials, performing heating and heat preservation, cooling to the room temperature, and filtering, thereby obtaining the formaldehyde decomposition liquid. Under mutual action of the raw materials, the formaldehyde decomposition liquid disclosed by the invention has a decomposition function on harmful organic matters such as formaldehyde and ammonia gases, further has a cleaning effect on cigarette smell, toilet smell, garbage smell, animal smell and the like, has functions of sterilization and purification, and is capable of effectively removing indoor environment pollution.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to formaldehyde decomposition liquid. Background technique [0002] Due to the use of artificial boards, wallpapers, foam plastics and other materials in newly decorated rooms, the indoor formaldehyde concentration is mostly higher than the national standard. Formaldehyde has a strong stimulating effect on the skin, eyes and respiratory tract, and has an anesthetic effect on the central nervous system. Formaldehyde coagulates proteins, is genotoxic to humans, and is also a mutagen. The symptoms of formaldehyde poisoning are as follows. Mild poisoning: obvious eye and upper respiratory tract irritation symptoms. The main manifestations are conjunctival hyperemia, redness, dyspnea, rough breathing, hoarse throat, dry speech or dull or wet greasy. The poisoned person can also feel that the sound of his breathing is getting thicker. Another specific manifestation o...
