Abstract
The invention relates to a high-efficient formaldehyde remover and a preparation method thereof. The high-efficient formaldehyde remover is used for efficiently removing formaldehyde remained after interior decoration. The formaldehyde remover consists of a component A and a component B, wherein the component A is a chlorine dioxide matrix component and is prepared from the following raw materials in parts by weight: 0.5-10 sodium chlorite, 40-120 water and 0.2-5 agar; the component B is a slowly-released activating agent component and is prepared from the following raw material in parts by weight: 0.5-18 slowly-released activating agent which is one or mixture of boric acid, citric acid, tartaric acid, oxalic acid, dihydric phosphate, sodium bisulfate and sulfamic acid. The high-efficient formaldehyde remover has easily realized preparation process, simple components, low cost, convenient use, safety and effectiveness; the releasing time of chlorine dioxide gas is long, and the released chlorine dioxide gas can rapidly oxidize the formaldehyde in the air and also have the purifying efficacy of sterilizing, deodorizing and the like.
Description
technical field [0001] The invention relates to an air purifier, in particular to a formaldehyde scavenging agent and a preparation method, belonging to the technical field of environmental protection products. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the decoration of office and family places is becoming more and more common, but improper decoration will also bring hidden dangers to people's health. In recent years, incidents of air pollution caused by interior decoration endangering the health of residents have occurred frequently, especially the formaldehyde contained in decoration materials, which has been confirmed as a strong carcinogen, mainly affecting the human respiratory tract. Allergic source, causing cough, chest tightness, asthma, various allergies, eye diseases and nasopharyngeal cancer, etc. At present, there are more than a dozen formaldehyde removers on the market, most of whi...
