Abstract

The application discloses formaldehyde trap spray and a preparation method thereof. The formaldehyde trap spray comprises, by weight, 30-50 parts of aloe extract, 30-50 parts of sweet potato leaf extract, 0.05-0.1 part of a hydrolyzing agent, 10-20 parts of a dispersant, and 100-120 parts of deionized water. The application also provides the preparation method of the formaldehyde trap spray. The technical problem is solved herein that an existing formaldehyde purifying method has low purifying efficiency, is severely affected by environment and easily causes secondary pollution.

Description

technical field [0001] The present application relates to the technical field of formaldehyde removal, in particular to a spray of formaldehyde trapping agent and a preparation method thereof. Background technique [0002] In recent years, with the gradual improvement of people's living standards, the problem of indoor air pollution has become increasingly prominent, which has aroused widespread concern from all walks of life. As one of the main indoor air pollutants, formaldehyde can enter the human body through the respiratory system and skin, which has potential, universal and long-term harm to the human body. Therefore, the purification of formaldehyde in indoor air is of great significance. Formaldehyde in indoor air is mainly released from interior decoration materials in a continuous and slow manner, and accumulates continuously indoors, resulting in excessive indoor formaldehyde concentration. Therefore, the purification method of formaldehyde needs to be effective...
