Abstract

The invention discloses a composite material capable of adsorbing alkaline waste gas and VOCs and used for air purification as well as a preparation method and application of the composite material. The composite material is prepared from 10-20 parts of activated carbon powder, 5-10 parts of aluminum oxide powder, 3-8 parts of zeolite molecular sieve, 3-5 parts of hydroxymethyl cellulose, 3-5 parts of chitosan, 2-5 parts of urea, 3-5 parts of calcium hypochlorite, 1-2 parts of dispersing agent, 1-2 parts of adhesive, 1-2 parts of bacteriostatic agent and the balance distilled water. The preparation method comprises the following steps of: weighing the raw materials in parts by mass; mixing and stirring the raw materials for 2-4 hours to obtain a mixed sample; transferring the mixed sample into a granulator, performing extruding and granulating through the granulator to obtain a primary product; putting the primary product into a dryer, drying the product for 2-4 hours to obtain a final product; and sieving the final product through a filter sieve so as to obtain the composite material capable of adsorbing alkaline waste gas and VOCs and used for air purification. The adsorption effect of the composite material on alkaline waste gas and VOCs is improved, and microorganisms such as bacteria and viruses are effectively inhibited and eliminated.

Description

technical field [0001] The invention belongs to the technical field of preparation of environmentally friendly materials, and in particular relates to a composite material for air purification that absorbs alkaline waste gas and VOCs, a preparation method and application thereof. Background technique [0002] With the rapid development of science and technology and economy, people pay more and more attention to the quality of life and life health. In daily life, people spend more than 80% of their time indoors every day. Therefore, the impact of indoor air quality on human health cannot be underestimated. In recent years, the problem of indoor air pollution has become more and more obvious, reducing work efficiency and quality of life, and even destroying the human immune system to induce physical diseases. [0003] The more serious pollutants in indoor environmental pollution are mainly formaldehyde, acetaldehyde, benzene series, ammonia, and some bacteria, viruses and micr...
