Abstract

The invention provides a rosin derivative material suitable for photo-cured printing ink and paints and a preparation method of the rosin derivative material. The rosin derivative material contains an esterification chain segment which is prepared by performing esterification on abietic acid resins and polyol in a reactor and an olefine acid ester chain segment which is prepared by continuously performing reaction on a rosin composition having the esterification chain segment and an organic solvent solution of an acrylic acid compound in a reactor. According to the preparation method of the rosin derivative resin, the production cost is reduced, and the final cured film performance test shows that the pencil hardness, the adhesion, the shock resistance and the weather resistance of a coating meet the basic application requirement, so that the rosin derivative resin has wide market prospect in the fields of photo-cured printing ink and paints.

Description

technical field [0001] The invention relates to a rosin acid derivative chemical, in particular to a rosin esterification chemical, and further relates to a UV curable oligomer synthesized by using a rosin derivative and a preparation method thereof. The invention belongs to light-curing materials, and is a rosin derivative resin suitable for light-curing inks and coatings. Background technique [0002] Rosin is a natural product with excellent properties such as insulation, adhesion, emulsification and thickening. It is also a renewable natural resin. It is known as "petroleum growing on trees" and can be widely used in paints, inks, rubber, It is an important industrial raw material in the fields of paper making, food additives and biological products. As human beings are concerned about the depletion of petroleum-based macromolecular monomer raw materials, the modification of resource-rich rosin into free radical polymerizable rosin macromonomer has become a current and ...
