Problems solved by technology

[0005] In summary, the formaldehyde scavengers of the prior art have the following disadvantages: they react slowly with formaldehyde, have low scavenging efficiency, and have inconspicuous scavenging effects; they are toxic themselves, and are easy to pollute the environment during production and use, and are easy to The room causes secondary pollution; the action time is short, and the formaldehyde that appears after using the agent is powerless

Abstract

The invention discloses a formaldehyde removing agent. Based on percentage by mass, the content of a plant extract is 5%-20%; the content of an accelerant is 1-5%; the content of a buffering agent is0.3-0.5%; the content of a water-based defoaming agent is 0.1-0.3%; the content of a wetting agent is 0.2-0.3%; the content of a stabilizer is 0.3-0.6%; the content of a penetrating agent is 0.5-1%; the content of a preservative is 0.2-0.5%; and the balance is water. In the plant extract, the mass ratio of a soybean extract to a green tea extract to a cocoa extract to a camphor tree leaf extract is 12:(18-30):(4-12):(6-18). The formaldehyde removing agent does not cause secondary pollution to the environment, meanwhile, formaldehyde reaction efficiency is high, and the removing capacity is high.

Description

technical field [0001] The invention relates to the technical field of formaldehyde removal, in particular to a formaldehyde scavenger and a preparation method thereof. Background technique [0002] In 2004, IARC (International Agency for Cancer) listed formaldehyde as a primary carcinogen, and formaldehyde has "three effects" of teratogenic, carcinogenic and mutagenic. When its concentration reaches 0.08-0.09mg / m3 in every cubic meter of air, children will have mild asthma. When the indoor air reaches 0.1mg / m3, there will be peculiar smell and discomfort; when it reaches 0.5mg / m3, it can stimulate eyes and cause tears; when it reaches 0.6mg / m3, it can cause throat discomfort or pain. When the concentration is higher, it can cause nausea and vomiting, cough, chest tightness, asthma and even pulmonary edema; when it reaches 30mg / m3, it will cause death immediately. Due to its high toxicity, the indoor formaldehyde concentration limit specified in GB / T18883-2002 "Indoor Air ...
