Problems solved by technology

Some of the existing formaldehyde scavenger are based on amine compounds such as urea and ethylenediamine as the main components. Although this type of formaldehyde scavenger can significantly remove formaldehyde, excessive use of this type of compound will cause ammonia to pollute again, causing indoor pollution. Ammonia has a strong smell and is not easy to remove, causing secondary pollution

Abstract

The invention belongs to the technical field of chemical preparations and particularly relates to a formaldehyde scavenger and a preparation method thereof. The formaldehyde scavenger comprises the following raw materials in parts by weight: 10-20 parts of amino acid, 10-20 parts of starch, 5-10 parts of casein, 5-10 parts of polysorbate, 10-15 parts of isoamyl alcohol, 30-50 parts of plant flower extracts, 5-10 parts of active carbon carboxymethylcellulose, 6-8 parts of a penetrant, 5-10 parts of pillared rectorite, 10-20 parts of chitosan and 80-120 parts of deionized water. The formaldehyde scavenger provided by the invention is high in absorption efficiency and capable of eliminating free formaldehyde in air, reducing the release amount of formaldehyde in a decorated product and simultaneously improving the stability of the formaldehyde in the decorated product so as to solve the problem of formaldehyde pollution caused after indoor decoration and the health of people is beneficial.

Description

technical field [0001] The invention relates to the technical field of chemical preparations, in particular to a formaldehyde scavenger and a preparation method thereof. Background technique [0002] Formaldehyde is an important chemical raw material and is widely used in industry. Some additives (such as phenolic resin, etc.) used in various chemical building materials or products will decompose during use to produce free formaldehyde, which will be gradually released into the environment, causing certain damage to people's living environment, especially human health. harm. 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 caus...
