Abstract
PURPOSE: A granulated amino resin molding material which shows improved heat stability in a kneader, is stable during granulation and can form moldings having excellent appearance, prepared by adding a lubricant to an amino resin molding material and granulating the mixture.
CONSTITUTION: An amino resin molding material is mixed with 0.5W5wt% lubricant and the mixture is granulated. The amino resins which can be used inclued urea resins, melamine resins, guanamine resins, and phenol-modified melamine resins. As the lubricants there can be mentioned aliphatic types, aliphatic amide types, metallic soaps, partial esters of fatty acids with polyhdric alcohols. With respect to the amount of a lubricant, amounts up to 0.5wt% have no effect to improve the heat stabiluty in a kneader and the appearance of a molding, and amounts exceeding 5% cause decreased kneadavility in a kneader. Accordingly, amounts of 0.5W5wt.% are preferred.
