Abstract
The invention discloses low-resistance powder paint. The low-resistance powder paint is prepared from, by weight, 60-70 parts of carboxyl-terminated polyester resin, 3-5 parts of hydroxyalkyl amide, 10-12 parts of conductive carbon black, 8-10 parts of aluminite powder, 4-5 parts of a conductive auxiliary, 1-3 parts of a luster-enhancing agent and 0.5-0.8 part of a flatting agent. The obtained low-resistance powder paint has good anticorrosion and antistatic performance and can have an effective protection effect after the surface of an electronic equipment container or shell, the surface of equipment sensitive to static discharge and the surface of household appliances are coated with the powder paint.
Description
Technical field
The invention belongs to technical field of coatings, be specifically related to a kind of low resistance powder coating.
Background technology
Electrostatic is when being separated after two kinds of material close contacts again, a kind of material passes to another kind of material and positively charged electronics, and another kind of material obtains electronics and electronegative generation.Although electrostatic electricity is little, because its voltage is very high, easily electric discharge occur and produce static sparking and set off an explosion, and electrostatic also can impact the normal operation of electronics.
Low resistance powder coating and antistatic powder coating, refer to the functional coating having certain conduction current and eliminate electrostatic, have the performance such as electromagnetic shielding, protection against corrosion, all have extensive use in each fields such as hyundai electronics, building, transport, military affairs.
Summary of the invention
The object of the present invention is to provide a kind of low resistance powder coating; there is good protection against corrosion, antistatic property; be coated in freight container or the shell of electronics, to the equipment of electrostatic discharge sensitive and the surface of home appliance, effective provide protection can be played.
For achieving the above object, the present invention adopts following technical scheme:
A kind of low resistance powder coating, it is raw materials used comprises by weight: terminal carboxyl polyester resin 60-70 part, hydroxyalkyl amide 3-5 part, graphitized carbon black 10-12 part, aluminium powder 8-10 part, conductive auxiliary agent 4-5 part, optical brightener 1-3 part, flow agent 0.5-0.8 part.
Preferably, it raw materials usedly comprises by weight: terminal carboxyl polyester resin 70 parts, hydroxyalkyl amide 3.8 parts, graphitized carbon black 12 parts, aluminium powder 8.4 parts, conductive auxiliary agent 4.2 parts, optical brightener 1 part, flow agent 0.6 part.
The preparation method of described low resistance powder coating is by after terminal carboxyl polyester resin, hydroxyalkyl amide, graphitized carbon black, aluminium powder, conductive auxiliary agent, optical brightener, flow agent mixing, melt extruded by forcing machine, then pulverize after extruded stock fragmentation, sieve through micro mist again, to obtain final product.
remarkable advantage of the present invention is: gained low resistance powder coating of the present invention, has good protection against corrosion, antistatic property, and its surface resistivity is 5 × 10
4~ 2 × 10
5Ω/cm, is coated in freight container or the shell of electronics, to the equipment of electrostatic discharge sensitive and the surface of home appliance, can be played effective provide protection.
