High-efficient formaldehyde remover and preparation method thereof

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...

Problems solved by technology

However, chlorine dioxide is unstable, difficult to store, and needs to be prepared on site, so a preparation method is needed

Chinese patent No. 200610134083.9 discloses a preparation method of a formaldehyde remover, which uses chlorine dioxide to remove formaldehyde, but the preparation and application methods of the product provided by this invention are very complicated, and the on-site application dosage form is liquid, not easy to move, effective short lifespan

Chinese patent No. 200710139426.5 discloses an aromatic slow-release chlorine dioxide gel powder and its preparation method, which also uses chlorine dioxide for air disinfection. formaldehyde and sterilize the air, but the product has complex components and high cost, and needs to be configured when used

Chinese patent No. 03118164.3 discloses controllable immobilized chlorine dioxide and its preparation process, which uses a gelling agent to make two-component gel substances for stable chlorine dioxide and acid activators respectively, and adds a large amount of calcium salt and Other substances have achieved the purpose of slow release and controllable release rate, but the addition of multi-component materials will cause waste. After a lot of research, we have proved that when the material ratio is appropriate, there is no need to add calcium salts and other substances, just rely on Gel matrix can also achieve the purpose of steady release of chlorine dioxide
