preparation example Construction

[0051] In the preparation method of the vinyl ester resin of the present invention, the equivalent ratio of the compound containing the epoxy resin structure to the unsaturated monocarboxylic acid is preferably 1:0.8-1.2, more preferably 1:0.9-1.1.

[0052] The compound containing epoxy resin structure can be bisphenol A type epoxy resin (Bisphenol A Epoxy Resin), bisphenol F type epoxy resin (Bisphenol F Epoxy Resin), novolac type epoxy resin (Novolac Type Epoxy Resin) ), Tetrabromo-Bisphenol A Epoxy Resin (Tetrabromo-Bisphenol A Epoxy Resin), one or more combinations, but not limited to the above options.

[0053] In the above-mentioned ring-opening polymerization step, as long as the compound containing the epoxy resin structure and the unsaturated monocarboxylic acid can be used for ring-opening polymerization, the polymerization conditions are not particularly limited, but preferably 90 Polymerization at ~130°C for 2 to 6 hours.

[0054] The vinyl ester resin of the pres...

Abstract

The invention discloses vinyl ester resin and a preparation method thereof, belongs to the technical field of high molecular materials, and provides a technical scheme, that is, vinyl ester resin which can be cured under a certain damp condition, for solving the problem that the conventional vinyl ester resin is greatly affected by moisture in the curing process. A compound with an epoxy resin structure generates ring opening polymerization reaction with unsaturated monocarboxylic acid and the generated product is diluted in a reaction type diluent to generate vinyl ester resin. The curing degree of the resin under the damp environment condition is increased, a novel solution to application of the vinyl ester resin to anti-corrosion construction in a damp environment is provided, the influence of the environment factor on construction is reduced, the construction period is shortened, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a vinyl ester resin cured under certain humid conditions and a preparation method thereof. Background technique [0002] Vinyl ester resin is a special unsaturated polyester resin with a vinyl group at the end of the molecule and an epoxy resin structure in the middle. It is usually prepared by ring-opening esterification of epoxy resin and unsaturated monobasic acid. , has the characteristics of two thermosetting resins, epoxy and unsaturated polyester; vinyl ester resin retains the basic chain segment of epoxy resin, and has good process performance of unsaturated polyester resin, which can be cured under suitable conditions , showing some special excellent properties, such as excellent mechanical properties, heat resistance and chemical resistance. [0003] The curing of vinyl ester resin is a free radical copolymerization reaction, generally using perox...
