Problems solved by technology

If these conditions are not met, as a relative phenomenon, the gaseous formaldehyde will increase, which is essentially equivalent to no removal effect at all. Even if it is removed to a certain point, the gaseous formaldehyde is released from the remover in turn, and finally the removal cannot be achieved. purpose
[0004] At present, the types and effects of formaldehyde removers on the market are still difficult to meet the growing needs of people. Therefore, it is urgent to develop a variety of formaldehyde removers

Abstract

The invention provides an environment-friendly efficient formaldehyde removal agent and a preparation method thereof, the environment-friendly efficient formaldehyde removal agent comprises the following raw materials: adipic dihydrazide, 2-imidazolidone, urea, carboxyl-terminated hyperbranched polyester, ethylene glycol, a surfactant, chitosan and hydroxyethyl cellulose, and a solvent is alkaline electrolyzed water. The preparation method comprises the following steps: 1, stirring adipic dihydrazide, carboxyl-terminated hyperbranched polyester, a surfactant, chitosan and hydroxyethyl cellulose at a low speed, and dispersing in alkaline electrolyzed water to form a glue solution; and 2, adding 2-imidazolidone, urea and ethylene glycol into the glue solution prepared in the step 1, and uniformly stirring at a low speed to prepare the environment-friendly efficient formaldehyde removal agent. According to the environment-friendly efficient formaldehyde removal agent disclosed by the invention, the adopted raw materials are pollution-free and environment-friendly, and the components contain the surfactant, so that the formaldehyde removal effect can be improved.

Description

technical field [0001] The invention relates to the technical field of aldehyde removal, in particular to an environment-friendly high-efficiency aldehyde removal agent and a preparation method thereof. Background technique [0002] Formaldehyde is a highly toxic substance, and it ranks second on the priority control list of toxic chemicals in my country. Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance, a recognized source of allergy, and one of the potential strong mutagens. Studies have shown that formaldehyde has strong carcinogenic and cancer-promoting effects. Its concentration reaches 0.08-0.09mg / m3 per cubic meter of air 3 When the child develops mild wheezing. When the formaldehyde content in indoor air is 0.1mg / m 3 odor and discomfort; up to 0.5mg / m 3 can irritate the eyes and cause tearing; up to 0.6mg / m 3 , can cause throat discomfort or pain. At higher concentrations, it can cause nausea and vom...
