Embodiment 1
[0028] A kind of functionalized silicon-containing acrylic resin based on catechol structure and preparation method and application thereof, comprising the following steps:
[0029]1) Equip the four-port reaction vessel with a stirrer, addition funnel, reflux condensing device, and thermometer respectively, add 25 parts of butanol and 30 parts of ethyl acetate, heat up to 100°C under stirring and keep it warm; then accurately weigh the methyl 30 parts of n-propyl acrylate, 4 parts of N-(3,4-dimethoxyphenyl) acrylamide, 25 parts of vinyltrimethoxysilane, 1.5 parts of diacetyl peroxide and uniformly mixed, the mixture was stabilized Add the drop rate into the four-port reaction vessel within 3 hours, continue to stir and keep warm for 2 hours to obtain the prepolymer; 2) Add 5 parts of hydrogen bromide aqueous solution to the prepolymer, heat and reflux for 1.5 hours and then change to distillation 3) Weigh 10 parts of functionalized silicon-containing acrylic resin based on cat...
Embodiment 2
[0031] A functionalized silicon-containing acrylic resin based on catechol structure and its preparation method and application, comprising the following steps:
[0032] 1) Prepolymerization: Add 40g of xylene and 8g of n-butanol into a four-necked reaction flask equipped with a stirrer, addition funnel, reflux condensing device, and thermometer, stir and heat up to 100-110°C and keep it warm. Then a homogeneous mixture of 4'-hydroxyl-3'-methoxyphenyl-2-propen-1-one, 32g methyl acrylate, 16g vinyltrimethoxysilane, 1.5g azobisisobutyronitrile was stabilized The dropping speed is added in the four-necked reaction flask within 4 hours, after continuing to stir and heat for 40 minutes, add dropwise a uniform mixture of 4g xylene, 4g n-butanol and 0.05g azobisisobutyronitrile in the four-necked flask within 1 hour. The mixture was continuously stirred and heated for 2 hours to obtain the prepolymer;
[0033] 2) Preparation: under stirring, add 10 g of hydrochloric acid to the prep...
Embodiment 3
[0036] A method for preparing a marine antifouling coating based on a catechol structure functionalized silicon-containing acrylic resin as a film-former, comprising the following steps:
[0037] Pre-polymerization: Equip the four-port reaction vessel with stirrer, liquid addition funnel, reflux condensing device, and thermometer, add 50 parts of xylene and 50 parts of butyl acetate, heat up to 100°C under stirring and keep it warm; then accurately weigh the formaldehyde 50 parts of butyl acrylate, 5 parts of N-(4-hydroxy-3-methoxyphenyl) acrylamide, 20 parts of acryloxypropyl trimethoxysilane, 2.0 parts of tert-butyl peroxybenzoate and Mix evenly, add the mixture into the four-port reaction vessel within 4 hours at a stable rate of addition, continue to stir and keep warm for 2 hours to obtain the prepolymer; introduce catechol structural functions into the side chain of the silicon-containing acrylic resin The chemical group increases the adhesion of the resin, reduces the c...
