Abstract

PURPOSE: To improve the thermal discoloration resistance, by adding, at specified ratio, ε-caprolactam and calcium carbonate to a polyester resin molding material containing a normally liquid crosslinking agent.
CONSTITUTION: In a polyester resin molding material prepared by adding a curing agent, filler, lubricant, coloring agent and additive to a polyester resin, iodine value 80W110, containing 5W25wt% normally liquid crosslinking agent; 8W16wt% polyester resin, 0.2W1wt% ε-caprolactam and calcium carbonate, average particle size 5W7μ, are mixed. It is required that the polyester resin used has an iodine value of 80W110. A convertional polyester resin, iodine value 60W70, is not suitable because of its marked thermal discoloration. It is required that the crosslinking agent be liquid at normal temperature. If the agent is solid, the productivity is markedly decreased because the amount of the resin which can be added is small.
