Abstract
PURPOSE: To prepare the titled modified resin having excellent compatibility with high molecular epoxy resins, and useful as an extender for color coating, by polymerizing the raw material of coumarone resin such as light oil and tar oil obtained from coal carbonization gas, in the presence of a specific amount of formaldehyde.
CONSTITUTION: Light oil or tar oil obtained from coal carbonization gas, is distilled to obtain the fraction having a boiling point of 110W200°C, which is used as a raw material of coumarone resin. 100pts.wt. of the raw material oil is mixed with 5W 80pts.wt. of formaldehyde or its oligomer, water, sulfuric acid, etc. and made to react by heating. After the completion of the reaction, the product is neutralized and washed to remove the catalyst, and the unreacted components are also removed from the product to obtain the objective liquid resin. A clear and homogeneous resin is prepared by mixing the resin obtained above with a high molecular epoxy resin, melting the mixture with heat, and cooling. The clear resin is dissolved in a solvent, and added with an additive, a hardening agent, etc. to obtain a coating composition.
