Abstract

The invention relates to a kind of amino acid pattern formaldehyde mundificant as well as its preparative method. The product is made up by the following components: 5-20% part of amino acid compounds, 0.1-5% part of penetrate, 1-10% part of humectants and water. The amino acid compounds adopted in the invention can react with formaldehyde completely at room temperature with a high reaction velocity. They can also react at very low temperatures. The product of the invention is the methylol derivates which is steady, atoxic, tasteless and nonvolatile; it also has the antisepticising ability and causes no secondary pollution. The cost of the material for the invention is very low and the preparing method is very easy. The product can remove the indoor formaldehyde effectively so as to purifying the air. Only by spraying or smearing the product in the air or on the surfaces of materials that contain formaldehyde can the invention eliminate the pollutants thoroughly.

Description

technical field [0001] The invention relates to a formaldehyde scavenger, in particular to an amino acid formaldehyde scavenger, and also to a preparation method of the amino acid formaldehyde scavenger. Background technique [0002] At present, after decorating living rooms, offices, and other indoor places for human activities, if decorative materials that do not meet environmental protection requirements are used, these materials will continuously release formaldehyde, and the release period is as long as 3-15 years. Pollution of the indoor environment. Formaldehyde has become the main substance of indoor air pollution. Formaldehyde is a substance with high toxicity. It ranks second on the priority list of toxic chemicals in my country. Formaldehyde has been identified as a carcinogenic and teratogenic substance by the World Health Organization. It is a recognized source of allergies and a potential strong carcinogen. One of the mutants, studies have shown that formaldeh...
