The invention discloses a method for preparing a myrcenyl
vinyl ester resin
monomer. The method comprises the following steps: adding unsaturated
carboxylic acid or anhydride into a reactor, and dripping
myrcene; reacting after dripping is ended, and thus obtaining myrcenyl
carboxylic acid or myrcenyl anhydride; adding myrcenyl anhydride and water in an equal
molar ratio into the reactor, adding
epoxy chloropropane, and stirring, so that the anhydride group is fully hydrolyzed; adding a catalyst A for reacting, or adding the myrcenyl
carboxylate or
epoxy chloropropane into the reactor, and adding the catalyst A for reacting; reducing the temperature and adding
sodium hydroxide and
calcium oxide; spreading
filter paper and diatomite, and performing reduced pressure suction
filtration to obtain filtrate; performing rotary
evaporation to remove excessive
epoxy chloropropane, and thus obtaining a myrcenyl epoxy resin intermediate; adding the myrcenyl epoxy resin intermediate, a catalyst B and a
polymerization inhibitor into the reactor, raising the temperature, dripping
acrylic acid into the reactor, reacting after dripping is ended, and thus obtaining the myrcenyl
vinyl ester resin
monomer. The prepared
vinyl ester resin is high in strength, high in
corrosion resistance and high in
weather resistance.
