Abstract

The invention provides an amino acid formaldehyde scavenger and an application thereof. The amino acid formaldehyde scavenger is composed of the following components in percentage by weight: 2-15% ofa plant amino acid extract, 0.5-5% of a surfactant, 0.1-2% of food-grade protease and 0.1-2.2% of active ions. According to the amino acid formaldehyde scavenger, pure plants are adopted to extract amino acid, and amino in the amino acid reacts with formaldehyde, so that the formaldehyde is decomposed into hydroxymethyl derivatives, water and other substances harmless to a human body, and the purpose of safely removing formaldehyde can be achieved.

Description

technical field [0001] The invention belongs to the technical field of indoor air pollution control, and in particular relates to an amino acid formaldehyde scavenger and its application. Background technique [0002] Indoor air pollution is 2-16 times that of outdoors, and some even exceed 100 times. Indoor air pollution has become an invisible killer endangering public health. After humans have experienced soot and photochemical smog pollution, people are entering the third pollution period marked by indoor pollution. And one of the most dangerous pollutants is formaldehyde. Sources of aldehydes and hazards to the indoor environment Formaldehyde mainly comes from building materials, plywood, flooring, adhesives, paints, furniture, etc. Since most wood-based panels contain urea-formaldehyde resins, phenolic resins, melamine-formaldehyde resins, etc., these substances in the process of use It will slowly decompose and release formaldehyde. This slow release exists for a l...
