Problems solved by technology

The bio-enzyme formaldehyde scavenger actually uses the protein and the side chain amino group of the polypeptide chain of the enzyme protein to capture formaldehyde, and has tea polyphenols to assist in capturing formaldehyde and has a certain antibacterial effect. The scavenger is rich in protein components, When used indoors, the utensils after spraying have the problem of mold staining, and only tea polyphenols in its formula have a certain antibacterial function, but the efficiency of inhibiting mold is low, and it is easy to emit new pollution after being infected with mold

Abstract

The invention discloses a safe indoor formaldehyde trapping agent and a preparation and use method thereof. The safe indoor formaldehyde trapping agent comprises, by weight, 100 parts of deionized water, 2-5 parts of formaldehyde condensating agent, 0.05-0.5 part of photocatalyst, 0.5-2 parts of condensation catalyst, 0.05-3 parts of leveling agent and 0.05-0.2 part of antibacterial agent. Compared with the prior art, the formaldehyde trapping agent is prepared from food-grade safe raw materials which only need to be mixed according to the formula ratio, and the process is simple; after beingprepared, the formaldehyde trapping agent is colorless, odorless and free of secondary pollution and is more suitable for indoor formaldehyde treatment, and after being sprayed, the formaldehyde trapping agent causes no corrosion to the surfaces of appliances, has high formaldehyde trapping and removing efficiency and can effectively suppress formaldehyde release and quickly eliminate formaldehydepollution of air. The formaldehyde trapping agent can be directly sprayed to the surfaces of formaldehyde release sources such as furniture, sofas, curtains and carpets to suppress formaldehyde release and can also be directly sprayed to formaldehyde-polluted air, used in combination with cold-volatilization air humidifiers, added into indoor water curtain landscape water and the like to quicklyreduce the concentration of free formaldehyde in air.

Description

technical field [0001] The invention belongs to the field of indoor formaldehyde treatment, and in particular relates to a safe indoor formaldehyde scavenger and a preparation and use method thereof. Background technique [0002] Indoor formaldehyde, especially in newly decorated rooms, has a high content of formaldehyde, and has the characteristics of high toxicity, wide sources and long release time, and is the main cause of many diseases. Long-term exposure to formaldehyde can cause headaches, dizziness, fatigue, sensory disturbances, decreased immunity, memory loss or neurasthenia, mental depression, and even respiratory dysfunction, hepatotoxic lesions, increased Hodgkin's lymphoma, multiple bone marrow Cancer, myelogenous leukemia and other special cancers are identified by the World Health Organization as carcinogenic and teratogenic substances. my country's "Indoor Air Quality Standard GB / T18883-2002" stipulates that the concentration of formaldehyde in the room air s...
