Problems solved by technology

Formaldehyde is a highly toxic substance, which has been determined by the World Health Organization as a carcinogenic and teratogenic substance. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, and nuclear gene mutations. Children and pregnant women are extremely harmful; the current methods for removing formaldehyde use ventilation, bamboo charcoal to adsorb formaldehyde or chemical formaldehyde purifiers, and the use of ventilation to remove formaldehyde cannot solve the source of pollution; the method of using bamboo charcoal to adsorb formaldehyde to remove formaldehyde is not obvious. Adsorption is slow, and when formaldehyde is saturated, it will no longer absorb, and the absorption rate is low; the effect of removing formaldehyde through chemical formaldehyde purifiers is obvious, but due to the use of chemical substances that can react with formaldehyde such as sulfate, ammonia, and urea to remove formaldehyde , the formed product is very unstable, easy to decompose and release formaldehyde, forming a secondary rebound of formaldehyde; and, because the release period of formaldehyde is as long as 15 years, it cannot be long-term committed to the removal of formaldehyde

Abstract

A microcapsule formaldehyde-removing agent and a preparing method thereof in the field of air purification are disclosed. The removing agent includes a core material and a wall material in a mass ratio of 1:2-6. The core material includes, by weight, 5-10 parts of tea polyphenols, 2-5 parts of aloe extract liquid, 3-5 parts of bracket plant extract liquid, 2-4 parts of Ottelia alismoides extract liquid, 5-10 parts of nanometer carbon black, 2-5 parts of nanometer silver, 2-3 parts of grape seed oil, 1-2 parts of cymbopogon citratus essential oil, 0.5-1 part of lavender essential oil, 0.5-1 part of eucalyptus essential oil, 3-10 parts of an emulsifier, 1.5-3 parts of a co-emulsifier, 1-3 parts of a dispersant and 1 part of a pH stabilizing agent. Uniformly dispersed formaldehyde-removing agent liquid particles are covered with a natural polymer film-forming material to form micro immobilized particles. Plant active components and the nanometer carbon black in the core materials are slowly released by passing through the wall material to remove formaldehyde in air, thus achieving an objective of removing formaldehyde for long term.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to a microcapsule formaldehyde remover and a preparation method thereof. Background technique [0002] With the improvement of housing reform and national living standards, especially the rapid development of building materials industry and the rise of decoration fever, the pollution caused by decoration materials has become the main source of indoor pollution. The newly renovated house will emit a large amount of formaldehyde due to the boards and paints in the furniture. The release cycle of formaldehyde is as long as 15 years, which directly affects people's living and office environment. Formaldehyde is a highly toxic substance, which has been determined by the World Health Organization as a carcinogenic and teratogenic substance. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, and ...
