The present invention discloses a kind of antimicrobial UV coating containing castor oil-base, includes the raw material components of following mass fraction：32~35 parts of castor oil-base UV cured polyurethane acrylates, 16~21 parts of organic silicon modified polyurethane acrylate, 8~10 parts of trimethylolpropane trimethacrylate, 5~6 parts of tripropylene glycol diacrylate, 15~16 parts of ethyl acetate, 14~15 parts of butyl acetate, 0.4~0.6 part of Siloxane-Oxyalkylene Copolymers levelling agent, 2.5~3 parts of photoinitiator, 0.95~1 part of nanometer silver antimicrobial auxiliary agent.The mixed solution being made of castor oil-base UV cured polyurethane acrylates and organic silicon modified polyurethane acrylate is coordinated to react the coating formed by Siloxane-Oxyalkylene Copolymers levelling agent, its levelling effect is good, volatile organic matter discharge is few, also there is water resistance, low temperature resistant, it is a kind of coating of high comprehensive performance and its electrical insulating property and adhesive force are even more superior. |
