Problems solved by technology

They contain toxic and harmful gases such as formaldehyde, benzene, TVOC and CO, which can cause respiratory diseases, endocrine abnormalities, skin allergies, blood diseases, cancer and other diseases that endanger human health. It will speed up, but the cycle of harmful gas volatilization can still reach 2-15 years
[0003] At present, there are many and miscellaneous formaldehyde removal products on the market. The most commonly used method is activated carbon adsorption, but activated carbon will reach saturation after adsorbing formaldehyde and other harmful gases. When the temperature rises, the formaldehyde and other harmful gases adsorbed in activated carbon can still be released. out, resulting in secondary pollution
In addition, there is a method of using photocatalyst, but photocatalyst needs light with high energy as the driving force. If the indoor light is insufficient or at night, it is difficult for photocatalyst to work.

Abstract

The invention provides a formaldehyde removing spray. A negative ion and photocatalyst composite technology is adopted, negative ion and photocatalyst materials are subjected to a series of treatmentincluding ball milling, calcination, ball milling, modification and the like, more photocatalyst powder and negative ion powder are coated with porous tourmaline powder, negative ions can be releasedeffectively for a long time, photocatalytic reactions can be performed for a long time under the condition of sufficient light sources, and the negative ion powder can eliminate free radicals and generate negative ions under the condition of weaker light sources. Therefore, the formaldehyde removing spray can continuously remove formaldehyde in various environments and has very high sterilization,deodorization, self-cleaning and air purifying effects.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a formaldehyde-removing spraying agent and a preparation method thereof. Background technique [0002] According to the latest indoor environment monitoring survey, the pollution of modern home decoration and the pollution of car interiors have become one of the most important reasons affecting human health. They contain toxic and harmful gases such as formaldehyde, benzene, TVOC and CO, which can cause respiratory diseases, endocrine abnormalities, skin allergies, blood diseases, cancer and other diseases that endanger human health. It will speed up, but the cycle of harmful gas volatilization can still reach 2-15 years. [0003] At present, there are many and miscellaneous formaldehyde removal products on the market. The most commonly used method is activated carbon adsorption, but activated carbon will reach saturation after adsorbing formaldehyde...
