Abstract

The invention provides efficient neutral formaldehyde capture agent, which consists of deionized water, melamine, formalin solution, methyl salicylate, isoamyl alcohol, polysorbate, diethyl phosphate, sodium dodecyl benzene sulfonate and activated carbon. The invention further provides a method for preparing the efficient neutral formaldehyde capture agent. The efficient neutral formaldehyde capture agent can rapidly react with formaldehyde to form innocuous and unpoisonous colorless transparent liquid with excellent stability, and can not produce secondary pollution for environment at the same time. The efficient neutral formaldehyde capture agent is low in cost of raw materials, simple and easy in production process, and simple and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a high-efficiency neutral formaldehyde scavenger and a preparation method thereof. Background technique [0002] Man-made panels such as plywood and particle board used in the decoration process, as well as materials such as wallpaper, wall covering and paint for decoration, will inevitably have residual formaldehyde. In recent years, with the extensive use of these decoration materials, the accompanying indoor formaldehyde pollution has always been a concern. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases. When the concentration of formaldehyde is high, it can cause physical decline, decreased immunity, easy to catch colds, hair loss, sharp loss of appetite, weight loss, general weakness, headache, angina pectoris and insomnia, etc. It can cause nuclear gene mutation, DNA single-bond cross-linking, DNA-protein cross-link...
