Problems solved by technology

However, the human body may fall and fall due to electric shock, causing secondary accidents
In addition, the electric shock can also cause the mental stress of the staff and affect the work
[0005] 3. Interfering with production Static electricity will hinder production or reduce product quality
In the textile industry, static electricity entangles fibers and absorbs dust, reducing the quality of textiles; in the printing industry, static electricity makes paper lines uneven and cannot be separated, affecting printing speed and printing quality; in the photosensitive film industry, static sparks make the film sensitive and reduce Film quality; in the powder processing industry, static electricity makes the powder adsorb on the equipment, affecting the filtration and transportation of the powder; static electricity may also cause malfunctions of electronic components; interfere with radio communications, etc.

Abstract

The invention relates to a low-resistance static conducting powder coating and a preparation method thereof. The low-resistance static conducting powder coating comprises the following components in percentage by weight: 35-50 percent of epoxy resin, 8-20 percent of curing agent, 10-30 percent of conducting mica powder, 0.5-3 percent of stainless steel powder, 15-30 percent of padding and 1-5 percent of auxiliary agent. The invention also discloses a preparation method and application of the powder coating. The method comprises the following steps of: adopting the high-performance epoxy resin as a film-forming substance; matching with the corresponding curing agent; and adding the conducting mica powder and the stainless steel powder. All basic performances of the project products are improved. The powder coating has lower cost, high safe performance, more category, attractive appearance and practicability, is quite suitable for being applied to industries, such as household appliance products, small household appliance products, electric power distribution cabinets, and the like and can insulate the static electricity of the household appliance products, which is accumulated on the surface of a coating in the running process in time so as to protect the physical and emotional safety and health of a human body.

Description

technical field [0001] The invention relates to a low-resistance electrostatic conductive powder coating and a preparation method thereof. technical background [0002] Static electricity is generated when two substances are in close contact and then separated, one substance transfers electrons to another substance and becomes positively charged, and the other substance receives electrons and becomes negatively charged. The common electrostatic phenomena in production are: frictional electrification, flow electrification, spray electrification, collision electrification, rupture electrification, droplet electrification and so on. There are three main types of electrostatic hazards: [0003] 1. Fire or explosion Fire and explosion are the greatest hazards of static electricity. Although the amount of static electricity is not large, it is easy to discharge due to its high voltage, resulting in static sparks. In workplaces with flammable liquids, such as oil shipments, fire...
