Problems solved by technology
Due to the use of a variety of man-made materials for decoration in today's interiors, there is a wide range of pollution and harmful gases such as formaldehyde and toluene, which have caused serious harm to people's health.
At present, air purification materials mainly remove harmful substances through physical adsorption, chemical methods, catalysis and other technologies. The commonly used physical adsorption materials mainly include activated carbon. Activated carbon can easily absorb harmful gases in the air because of its large specific surface area. It is widely used in indoor air purification in daily life, while activated carbon can only absorb harmful gases and cannot filter larger air pollutants

The invention discloses a preparation method of a material for air purification. The preparation method comprises: (1) taking 1.6-2 parts by weight of dibenzoyl peroxide, adding to deionized water accounting for 30-40 times the weight of the dibenzoyl peroxide, and uniformly stirring; (2) taking 2-3 parts by weight of triethylamine, adding to absolute ethanol accounting for 5-7 times the weight ofthe triethylamine, and carrying out stirring dissolving; (3) taking 47-50 parts by weight of carbon powder, and adding to a sulfuric acid solution accounting for 3-4 times the weight of the carbon powder to obtain an activated carbon powder solution; (4) adding 80-100 parts by weight of deionized water, and completely mixing and stirring; (5) taking 20-30 parts by weight of methyl methacrylate, feeding into a reaction kettle, introducing nitrogen gas, and drying at a room temperature to obtain an activated carbon powder deposition polymer; and (6) adding a foaming agent to the carbon powder deposition polymer, and drying for 1-3 h to obtain the air purification material. According to the present invention, the material can enhance the air purification ability of the finished product, andfurther has a certain disinfecting effect so as to enhance the air purifying ability.
Description
technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a preparation method of a material for air purification. Background technique [0002] Air purification refers to providing overall solutions for various indoor environmental problems such as sterilization and disinfection, dust reduction and haze removal, removal of harmful decoration residues and peculiar smells, etc., which can effectively improve living and office conditions, and enhance physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gas, mold, particulate matter, decoration residue, second-hand smoke, etc. Due to the use of various artificial materials for decoration in today's interior, there is a wide range of pollution and harmful gases such as formaldehyde and toluene, which have caused serious harm to people's health. At present, air purification materials mainly remove harmful substance...
