Formaldehyde scavenging agent capable of accelerating formaldehyde release speed

Abstract

The invention discloses a formaldehyde scavenging agent capable of accelerating formaldehyde release speed. The formaldehyde scavenger is prepared from the following raw materials: garlic residues, potassium chloride, calcium metaborate, sodium hydroxide, deionized water, monstera deliciosa leaves, maleic anhydride, imidazolidinyl urea, stellerite powder, casein, menthol, activated carbon carboxymethyl cellulose and a stabilizer. The preparation method of the formaldehyde scavenging agent for accelerating formaldehyde release speed comprises the following steps of: soaking deodorized garlic residues, monstera deliciosa extract and modified stellerite in a chemical solution prepared from potassium chloride, calcium metaborate, sodium hydroxide, casein, menthol, activated carbon carboxymethyl cellulose and deionized water; adding maleic anhydride, imidazolidinyl urea and activated carbon carboxymethyl cellulose, performing stirring, making an obtained mixture stand still, pouring filter residues into a stabilizer, soaking the filter residues with the stabilizer, performing filtering, and drying at low temperature under reduced pressure to obtain formaldehyde scavenging powder; and packaging the formaldehyde scavenging powder to obtain a finished product of the formaldehyde scavenging agent. The formaldehyde scavenging agent of the invention has the advantages of low cost, environmental protection, high efficiency, no secondary pollution, and lasting and effective adsorption effect.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a formaldehyde scavenger for accelerating formaldehyde release. Background technique [0002] With the development of the economy and the improvement of people's living standards, a large number of new homes have been built, and the interior decoration has become more and more exquisite. my country's "Indoor Air Quality Standards" stipulates that the maximum allowable concentration of formaldehyde in the living room is 0.10mg / m3, which is extremely high. In most newly renovated homes, the indoor formaldehyde concentration exceeds the standard by several to ten times within 5 to 10 months after the decoration is completed. Residents usually adopt relatively passive methods such as opening windows for ventilation or waiting for a period of time before living, which causes great inconvenience to life; Formaldehyde has a strong stimulating effect on human skin and mucous membr...

Problems solved by technology

[0003] At present, the main method for people to eliminate formaldehyde pollution in indoor air is to use formaldehyde scavenger. However, the common problems of common products and patented technology products sold on the market are: 1. The price of formaldehyde scavenger is high and the elimination effect is poor. , which is characterized by limited amount of formaldehyde removal within a certain period of time and poor persistence of the effect. Usually, the validity period of these formaldehyde removers is only a few days; 2. Most formaldehyde removers are sprayed on the surface of wood-based panels or furniture by one or more times. To eliminate the emitted formaldehyde, it is inconvenient to use, and it brings additional processing costs to consumers, and there is a problem of secondary pollution; based on the above problems, it is necessary to provide a method that can induce the release of formaldehyde and efficiently absorb formaldehyde in furniture in a short period of time. Formaldehyde scavenger, no secondary pollution, environmentally friendly and cheap new formaldehyde scavenger to meet the needs of use
