High-power transformer enameled wire paint
High-power transformer enameled wire paint includes the raw material of following parts by weight：Methacrylic acid ethylidene-urea ethoxylated ester 50 parts, 28 parts of polyethyleneglycol diacrylate, 8 parts of hydroxyethyl methacrylate, 4 parts of acid anhydride type curing agent, rilanit special 1.5 Part, 4 parts of Sodium Polyacrylate, 4 parts of ternary polycarboxylic acids, 1 part of chloro fat hydrocarbon, 25 parts of compounded mix, 30 parts of double solvents, levelling agent 1.5 parts, 0.5 part of initiator, 0.6 part of crosslinking agent, 1 part of dispersant；
Wherein, the compounded mix by nano-calcium carbonate calcium powder, sodium bentonite, magnesia with weight ratio 7:3:1 is mixed to get；
Wherein, double solvents by methyl iso-butyl ketone (MIBK), butyl acetate, L-phenylalanine with weight ratio 9:4.5:1 is mixed to get.
Wherein, the compounded mix is before use, complete when drying process 2.5 is small under temperature is 80 DEG C of vacuum condition It is 20-400nm that particle diameter is ground to after；The acid anhydride type curing agent is phthalic anhydride；The levelling agent is acrylic acid tree Fat is with polymethylphenylsiloxane with weight ratio 1:3 are mixed to get；The initiator is potassium peroxydisulfate；The crosslinking agent is N- hydroxyls Methacrylamide；The dispersant is oleyl amine acetate.
Wherein, its preparation method is：It is 50 DEG C in temperature, with 3400 revs/min of high speed dispersions of rotating speed, is then added to and grinds In grinding machine, it is ground to particle diameter less than 20 μm, to obtain the final product.
After testing, its water absorption rate is 0.65%, and impact strength reaches 53.8kgcm, is located under conditions of being 300 DEG C in temperature Manage 12 it is small when, its impact strength conservation rate reaches 98.6%.
