Problems solved by technology

Adsorption technology mainly uses high specific surface materials such as activated carbon and molecular sieves to adsorb formaldehyde to achieve the purpose of purifying the air. However, the currently available adsorption materials on the market have limited adsorption capacity, poor stability, low reuse rate, and need to be regularly regenerated or replaced. produce secondary pollution

Abstract

The invention discloses a rare-earth composite air purifying material. The rare-earth composite air purifying material is prepared from, by weight, 1-2 parts of 6-hydroxyl-2-naphthoic acid, 20-30 parts of rare-earth dispersion liquid, 0.1-0.2 part of monobutyltin oxide, 1-2 parts of calcium palmitate, 80-90 parts of scolecite, 20-30 parts of nano carbon powder, 3-4 parts of diphenyl silanediol and0.8-1 part of formamide. The calcium palmitate and the monobutyltin oxide are also added in the material, the heat-resistant stability of the finished product material can be effectively improved, and the rare-earth composite air purifying material has strong adsorbability, good environmental friendliness and superior overall performance and is safe in use.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a rare earth composite air purification material and a preparation method thereof. Background technique [0002] With the improvement of people's material and cultural living standards, interior decoration has become fashionable, and what follows is that the pollution of indoor air is becoming more and more serious. And for most people, regardless of work, study or life, people spend most of their time indoors or in closed spaces such as cars. Although the harm of air pollution to human health has long been recognized by people, people's attention has gradually shifted to the harm of indoor air pollution to human health until the middle of the 20th century. There are many types of indoor air pollution, more extensive pollution sources, and complex influencing factors. The harm to human health is often more serious than outdoor air pollution. Indoor air qualit...
