Description
Technical field
The present invention relates to synthetic resin and plastics arts, and in particular to a kind of band epoxy radicals acrylic resin is modified ring
The preparation method of oxygen resin anti-corrosive paint.
Background technology
Due to the influence of ocean harsh and unforgiving environments, metal is easily corroded.Prevent one of the most frequently used measure of metal erosion
It is exactly brushing anticorrosive paint, and in anticorrosive paint, anti-corrosive paint of epoxy resin is one of kind being most widely used.Epoxy
Resin contains the functional groups such as hydroxyl, epoxy radicals, and the space structure formed after being crosslinked with curing agent such as amine, acid anhydrides, esters is determined
Having determined it has excellent adhesive strength, resistance to corrosive chemicals, insulating properties and mechanical strength；But there is also all for epoxy resin
More drawbacks（Such as due to phenyl ring be present in epoxy resin, cause its weatherability and ultraviolet resistance poor；Anti-corrosive paint of epoxy resin is consolidated
Re-coating layer ply adhesion reduces after change, is easily caused the peeling of coating interlayer；The internal stress of epoxy resin is larger etc.）, therefore pure epoxy
The application of resin anti-corrosive paint is restricted.In recent years, substantial amounts of work has been done in modification of many scholars to epoxy resin, main
It is divided into physical modification and chemical modification.Acrylic resin is because its excellent weatherability, pliability and good recoatability are in thing
It is widely used during reason is modified.The ply adhesion of anti-corrosive paint of epoxy resin can be improved by being incorporated into epoxy resin.
The content of the invention
A kind of the present invention is directed to propose preparation method with epoxy radicals acrylic resin modified epoxy anticorrosive paint.
Technical program of the present invention lies in：
Preparation method with epoxy radicals acrylic resin modified epoxy anticorrosive paint, comprises the following steps：
（1）The synthesis of acrylic resin：
Methyl methacrylate, butyl acrylate are taken, mercaptan mixes in beaker, takes initiator solution standby；To 1 000 mL
Add 196.8 g butyl acetates in three-necked flask, open condensed water and added after being warming up to 80 DEG C 3.0 g initiator solutions and
30.0 g mix monomers, interruption add mix monomer and initiator, are incubated 1 h and add 3.0 g initiators, then are incubated 2 h, make
Obtain acrylic resin；
（2）Coating preparation：
Acrylic resin is mixed with epoxy resin, and compounds rust resisting pigment, filler preparation coating.
Described epoxy resin and the mass ratio of acrylic resin are 9: 1.
Described methyl methacrylate quality is 150.2 g, and butyl acrylate quality is 96.0 g, and mercaptan quality is
2.40 g。
Described initiator solution is dissolved in 50.0 g butyl acetates for 0.4 g azodiisobutyronitriles and obtained.
It is to draw every 15 min, 38.3 g mix monomers of addition and 8.0 g that described interruption, which adds mix monomer and initiator,
Send out agent.
The technical effects of the invention are that：
The present invention has synthesized band epoxy radicals acrylic resin using radical polymerization, and polymerization, and polymer completely occurs for monomer
Band epoxy radicals；With the increase of initiator and chain-transferring agent dosage, the viscosity with epoxy radicals acrylic resin declines；With pure epoxy
Resin anti-corrosive paint is compared, and the ply adhesion of modified epoxy anticorrosive paint is higher.
