Abstract

The invention discloses a porous zeolite air purification material. The material comprises, by weight, 37-40 parts of porous stone powder solution, 20-30 parts of acrylamide, 0.4-1 part of sodium diacetate, 3-4 parts of borax, 2-4 parts of aluminum dihydrogen phosphate, 1-2 parts of HEDP, 0.7-1 part of polydimethylsiloxane, 1-2 parts of calcium propionate, 2-4 parts of polyvinyl alcohol and 0.7-0.8 part of ammonium persulfate. Acrylamide serves as a monomer, HEDP is doped, and polymerization is conducted under the effect of an initiator, so that polymer emulsion is obtained; then the polymer emulsion is mixed and reacts with the polyvinyl alcohol solution of porous stone powder, the compatibility between the compound stone powder and the polymer is effectively improved, and then the stability of a finished product material is improved. The porous material has a good adsorption effect and is high in repeating utilization rate.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to a porous zeolite 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 quality research has...
