Carbon fiber is cut into 2～5mm, is then immersed in 10h in acetone soln, then with deionized water to carbon fiber Clean 3～5 times；At room temperature, the carbon fiber after cleaning is immersed in concentrated nitric acid, takes out, then use deionized water after 1h Repeatedly clean, next put into oscillation cleaning 1h in supersonic cleaning machine, at 100 DEG C, be dried 2h；Dried carbon fiber is put into In magnetic control sputtering device, 10-4It is deposited with one layer of copper film at carbon fiber surface under Pa base vacuum, obtains copper carbon fiber；
Step 2, process copper powder:
50ml dehydrated alcohol concentrated hydrochloric acid solution is formulated in clean container, then weighs 25g copper powder and put in container, By solution stirring 1h, it is purified, then rinse 3 times with ether and dehydrated alcohol, until by-product HCl and CuCl2 Clean from Copper Powder Surface, then copper powder is placed in vacuum drying oven, take out standby after being dried 12h；
Step 3, prepares unsaturated-resin:
Take cis-butenedioic anhydride 0.44mol, phthalic anhydride 0.06mol, poly-400 0.145mol of disodiumedetate, propylene glycol 0.12mol, ethylene glycol 0.18mol, butylene glycol 0.05mol, add 0.3mol NaOH, 0.1% catalyst dibutyltin cinnamic acid two fourth Ji Xi, the polymerization inhibitor MEHQ mixing of 5/10000ths, fill this blend in the 250ml there-necked flask of band water knockout drum, It is placed in conduction oil, electric stirring, 160 DEG C of nitrogen atmospheres react 60min；It is warmed up to 180 DEG C, melt polymerization in nitrogen atmosphere 120min, then it is warming up to 195 DEG C, in nitrogen atmosphere, melt polymerization is 60 to acid number, is cooled to 100 DEG C and pours out, obtains after cooling The transparent unsaturated-resin of buff；
Step 4, prepares antistatic coating:
First weigh unsaturated-resin 100ml, add 5g copper powder and copper carbon fiber, be sufficiently mixed, add 3% silicon Alkane coupling agent, by mixture mechanical agitation, obtains antistatic coating.
Preferably, the antistatic coating prepared being coated in target object surface, coating thickness is 1～3 μm, then will It irradiates under distance ultraviolet source 10cm and makes curing of coatings.
Show it is further preferred that antistatic coating involved by the application to be carried out antistatic test, when copper powder adds Amount mass ratio is 25%, and when copper powder and copper carbon fiber mass ratio are 3:4, the surface resistivity of described antistatic coating is 3.5×107Ω/cm2；After 60 days, aging resistance test shows, surface resistivity variable quantity is less than 5%.
Those skilled in the art, after considering description and putting into practice invention disclosed herein, will readily occur to its of the present invention Its embodiment.The application is intended to any modification, purposes or the adaptations of the present invention, these modification, purposes or Person's adaptations is followed the general principle of the present invention and includes the undocumented common knowledge in the art of the application Or conventional techniques means.Description and embodiments is considered only as exemplary, and true scope and spirit of the invention are by following Claim is pointed out.
It should be appreciated that the invention is not limited in precision architecture described above and illustrated in the accompanying drawings, and And various modifications and changes can carried out without departing from the scope.The scope of the present invention is only limited by appended claim.
