Preparation method and application in coating.
Technical background
Water paint is low due to its consumption of organic solvent, both can alleviate the consumption to petroleum resources, can be greatly lowered again
VOC emission, it has also become the study hotspot of various environment-friendly type coatings.The Water-borne modification of resin is by introducing polar group in system
Implement, the hydraulic performance declines such as the adhesive force of solidification coating, resistance to water, film strength can be made accordingly.Therefore, how tree is being improved
The while that fat being water miscible, ensure that the solidification high performance adhesive force of coating, resistance to water, film strength are water paint industrialization
Key issue.In recent years, patent (CN1474838A) discloses one and prepares waterborne acrylic modified alkyd resins: first prepare
A kind of sulfonate alkyd resin product, then prepares a kind of acrylated fatty acid product, finally both products suitably
React under polymerizing condition.This kind of product solves the dry problem of alkyd resin, but owing to its ester group is not protected,
Being easily broken off degrading in aqueous environment, therefore resistance to water or poor, bin stability need to improve.Patent
(CN1375535A) disclosing and synthesized by core-shell emulsion technology a kind of with alkyd resin as core, acrylic polymer is shell
Self-emulsifying nanometer emulsion.This emulsion is successfully realized acrylic polymer " parcel " of alkyd resin ester group, thus
Solve the storage stability of single aqueous alkyd resin, but this technique preparation process is complex and is only
Strength problem after solving the resistance to water problem of water-base resin and not improving resin film forming, in order to enable water-base resin
In the face of harsher applied environment expand application, the mechanical strength after its film forming must also be improved further.Patent
(CN101864044A) a kind of aqueous acrylic modified epoxy ester resin of addressing use nucleocapsid structure technology by vinyl-based or
The polymer overmold that acrylic monomer obtains through polyreaction in esterification after epoxy resin outside, prevent the ester group of inside
It is hydrolyzed, but nucleocapsid structure technology preparation technology is relatively complicated, the higher development being unfavorable for market of production cost, and be coated with
Each physical performance index such as film-strength does not the farthest reach solvent-borne type standard.Therefore, aqueous acrylic modified epoxy ester is developed at present
The task of top priority of resin is to possess excellent adhesion, high hydrolysis resistance increasing substantially water miscible the preparing of epoxy resin simultaneously
Property, the high-performance water-basedization resin of high film strength, be further prepared into water paint on this basis.
Summary of the invention
