An antistatic brick prepared from copper tailings and its preparation method and application

Abstract

The invention discloses an antistatic brick prepared from copper tailings, a preparation method and application thereof, and belongs to the technical field of building materials. The preparation method uses copper tailings as the raw material, after being crushed, sieved to obtain a suitable particle size, adding iron oxide, PVB resin powder and water, fully stirring, and then forming, drying, and sintering to obtain antistatic bricks . The method has a simple process and is suitable for large-scale production. The raw material is copper tailings discarded by copper mines. While obtaining low-cost raw materials, it also solves the problem of copper tailings polluting the environment. The antistatic brick prepared by the above method has good antistatic performance, high strength and porosity, and good thermal conductivity. When the prepared anti-static brick is used as a building material in large public places and special laboratories, it can effectively prevent and eliminate the impact of static electricity, and ensure personal safety and the operation of precision equipment.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an antistatic brick prepared from copper tailings, a preparation method and application thereof. Background technique [0002] Static electricity is more harmful in some fields such as semiconductor equipment and microelectronic equipment, electronics, medicine and food, precision instruments and biotechnology. Electromagnetic waves generated by static electricity may interfere with the operation of some precision equipment and cause large deviations; or in concentrated personnel Fires occur in places, such as subways, airports, gas stations, etc. Therefore, it is very necessary to carry out electrostatic protection for these places. At present, antistatic materials for construction are mainly organic polymer materials, such as antistatic PVC boards, antistatic PC boards, etc., but polymer materials are prone to aging and cause fires. Although floor tile ...
