Abstract

The invention relates to an antistatic material used for a purifying and filtering layer. The antistatic material comprises the following raw materials in parts by weight: 20-30 parts of an acrylic emulsion, 10-14 parts of nano zinc oxide fiber, 8-12 parts of conductive mica powder, 10-14 parts of graphene, 10-20 parts of deionized water, 1-3 parts of a dispersing agent, 0.5-2 parts of an antifoaming agent, 1-2 parts of a leveling agent, 1-2 parts of a thickener, and 1-2 parts of a film-forming auxiliary. The antistatic material has the beneficial effects that (1) the antistatic coefficient ofthe antistatic material is high, and no static phenomenon occurs in dry air; (2) the antistatic material has high hardness and long service life; and (3) the used nano zinc oxide fiber avoids the disadvantage that the density of the metal powder is large, and a formed conductive path requires a large volume fraction, and the influence on the other properties of the coating formed by the antistatic material is reduced.

Description

technical field [0001] The invention belongs to the field of purification equipment, and in particular relates to an antistatic material used for purifying a filter layer. Background technique [0002] Purification equipment refers to the ability to absorb, decompose or transform various air pollution sources and air pollutants (indoor biological pollution. Mainly including bacteria, fungi, molds, viruses, dust mites, pollen, pet dander, organic components of organisms, etc.), Products that effectively improve air cleanliness are currently dominated by household and industrial purification equipment that removes indoor air pollution. [0003] Antistatic material refers to the material that has the least amount of charge generated when the same material or other similar materials rub against each other or separate. [0004] gold [0005] The antistatic coefficient in the existing purification filter layer is low, and static electricity often occurs in dry air; the metal pow...
