Abstract

The invention discloses a styrene-free high-chemical-resistance ultraviolet-curing vinyl ester resin composition. The styrene-free high-chemical-resistance ultraviolet-curing vinyl ester resin composition comprises the following components: 100 parts of vinyl ester resin, 90-110 parts of a diluting monomer, 0.1-3.0 parts of a coupling agent and 1-5 parts of a photoinitiator. According to the styrene-free high-chemical-resistance ultraviolet-curing vinyl ester resin composition, as the non-styrene diluting monomer is adopted, even if VOC dissipation exists in an operation environment in the curing process, the smell and the toxicity are greatly reduced, and the friendliness to the environment and operation workers is greatly improved; a cast sheet obtained by UV-irradiation curing of vinylester resin has a favorable characteristic of resisting a chemical solvent; the chemical solvent resisting characteristic is obviously improved in comparison with traditional vinyl ester resin; and particularly, the methyl alcohol resisting characteristic is improved remarkably.

Description

technical field [0001] The invention relates to the field of chemical anticorrosion raw materials, in particular to a styrene-free high chemical resistance ultraviolet light curing vinyl ester resin composition. Background technique [0002] Vinyl ester unsaturated resin refers to unsaturated polyester with vinyl groups at both ends of the molecule and epoxy resin as the middle skeleton. It is a new type of resin developed in the 1960s. They are obtained by the ring-opening esterification reaction of unsaturated organic monocarboxylic acid such as acrylic acid or methacrylic acid and epoxy resin, so they can also be called unsaturated acid epoxy ester resin. The unique molecular structure of this vinyl ester unsaturated resin makes it have the advantages of both unsaturated polyester resin and epoxy resin: on the one hand, it is similar to unsaturated polyester resin, has lower viscosity, and is easy to process and shape. Under the action of a free radical initiator, it can...
