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 shell powder reinforcing air purification material. The material is prepared from, by weight, 16-20 parts of activated shell powder, 1-2 parts of melamine, 0.5-1 part of sodium alkylbenzene sulfonate, 2-4 parts of trimethylolpropane, 5-7 parts of methylpyrrolidone, 65-70 parts of diatomaceous earth, 1-2 parts of tetradecanedibasic acid and 0.8-1 part of 1,2-dimethylimidazole. The dispersion compatibility among the raw materials is improved, the stability of the finished material is improved, the cost of the material is low, the recycling rate is high, and the safety and environmental-protection performance are great.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a shell powder reinforced 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 qua...
