| titleOfInvention | Air-drying unsaturated polyester resin for easy-polishing gel coat, and preparation method thereof |
| abstract | The present invention relates to the technical field of polymer material preparation, and especially to an air-drying unsaturated polyester resin for an easy-polishing gel coat, and a preparation method thereof. The resin is prepared by the following steps, wherein the steps comprise that: an organic polyol and a renewable vegetable oil are subjected to an ester exchange reaction, and then are subjected to a condensation polymerization with a small molecule dihydric alcohol or a dibasic acid, tetrahydrophthalic anhydride and allyl ether; the formed polymer is dissolved in styrene to prepare the resin. The air-drying unsaturated polyester resin of the present invention has the following advantages that: (1) the renewable vegetable oil is selected as the main component, such that the use of the toxic and harmful chemical engineering raw materials is reduced so as to meet the green environmental protection concept; (2) the vegetable oil, the tetrahydrophthalic anhydride, the allyl ether and the like in the resin component provide good air-drying properties, such that the resin can be widely applicable for the fields with high air-drying requirements. The resin of the present invention is mainly applicable for the easy-polishing gel coat with the high air-drying requirements, and has characteristics of excellent toughness, excellent adhesion, excellent weather resistance, excellent polishing property and the like. In addition, the resin of the present invention has good air-drying property, and the gel coat prepared by the resin of the present invention has characteristics of good adhesion, low porosity, easy polishing and the like. |
