Abstract

The invention provides an antistatic composite material, a preparation method of the antistatic composite material, an antistatic shell and a purifier. The antistatic composite material is prepared from resin, an antistatic agent, a silane coupling agent and solubilizer. The antistatic composite material has the resistance being between 106 and 109 omega by limiting the content of resin, antistatic agent, silane coupling agent and solubilizer, the antistatic effect can be improved by leading the raw materials to achieve a critical running-in point, attenuation and loss of static electricity inthe antistatic composite material are accelerated, and purification of static electricity on the inner surface of a purifier shell is not influenced, so that the static electricity transferring process is not obstructed, the outer surface of the purifier shell is not influenced by the static electricity on the inner surface of the purifier shell, the problems of ash accumulation on the outer surface of the shell and impact on operator safety can be solved, and the dust collection efficiency of a purifier can be improved.

Description

technical field [0001] The invention belongs to the technical field of electrostatic protection, and in particular relates to an antistatic composite material, a preparation method, an antistatic shell and a purifier. Background technique [0002] Purifiers are often used to purify air or water bodies. Among them, purifiers that purify air are called air purifiers. Air purifiers are those that can absorb, decompose or transform various air pollutants (generally including PM2. , formaldehyde and other decoration pollution, bacteria, allergens, etc.), products that can effectively improve air cleanliness, mainly divided into household, commercial, industrial, building, etc. [0003] There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, catalytic technology, photocatalyst technology and electrostatic dust collection technology, etc....
