Abstract

The invention discloses an efficient and environment-friendly formaldehyde cleaning agent, which is prepared from the following components in percentage by mass: 30 to 46 percent of deionized water, 2 to 4 percent of ammonium acetate, 6 to 12 percent of glacial acetic acid, 0.2 to 0.5 percent of acetylacetone, 8 to 10 percent of herba houttuyniae, 9 to 12 percent of picrasma quassioides, 6 to 8 percent of radix isatidis, 5 to 8 percent of semen cassiae and 15 to 20 percent of absolute ethyl alcohol. The preparation method comprises the following steps: mixing and mashing the herba houttuyniae, the picrasma quassioides, the radix isatidis and the semen cassiae according to the proportion, then putting the mixture into a distillation flask, adding absolute ethyl alcohol, conducting stirring for 6-10 minutes at room temperature, conducting standing for 20-30 hours, then conducting heating and refluxing for 1-3 hours, conducting centrifugal separating, taking supernate, and conducting filtering by using a microfiltration membrane to obtain filtrate for later use; and adding ammonium acetate, glacial acetic acid and acetylacetone into deionized water, ultrasonically conducting stirring for 5-10 minutes, adding the filtrate, conducting refluxing for 1-2 hours at the temperature of 50-65 DEG C, and conducting cooling and standing to obtain the cleaning agent.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to an efficient and environment-friendly formaldehyde cleaning agent and a preparation method thereof. Background technique [0002] Formaldehyde is one of the strong teratogenic substances recognized by the medical field. Formaldehyde is colorless and has a strong irritating gas. It is widely used in wood, textile, printing and other industries. Formaldehyde has high toxicity. People live with it for a long time The environment of formaldehyde will have great harm to your life, safety and health. Formaldehyde is also carcinogenic. At present, we only remove formaldehyde from our indoor air. Various artificial boards (particle board, density board, fiberboard, Plywood, etc.) contains formaldehyde due to the use of urea-formaldehyde resin adhesives. [0003] The main source of formaldehyde is building decoration materials. These materials continuously volatilize ...
