초록 ▼

Description of a method for the production of a pigmented thermoplastic material. The method characterizes that during a first step an aqueous suspension presenting a solid matter contents of approximately 10 to 75% by weight, containing at least one flow enhancer in form of dissolved salt and the pigment, is ground under alkaline conditions in a high energy charging mill by means of grinding bodies having a diameter of 0.2 to 2 mm, and the obtained grinding product is transformed during a second step with a thermoplastic material into the pigmented thermoplastic material by means of a flush process performed by a kneader or extruder, at increased temperature and a pH value of initially 7 or less. In addition, the invention concerns a pigmented thermoplastic material produced according to said method, as well as beneficial applications for production of transparent molded bodies, in particular of fibers, foils, injection moldings and extruded parts. The invention-specific method provides pigmented plastic material which can reliably be processed into high quality products. Foils which are produced accordingly are, for example, free from coloration defects.

The invention claimed is: 1. A method for the production of a pigmented thermoplastic material, characterized in that in a first step an aqueous suspension, presenting a solid matter contents of approximately 10 to 75% by weight, which contains a flow enhancer in form of a dissolved salt and the pigment is ground under alkaline conditions in a high-energy feed mill with grinding bodies having a diameter of 0.2 to 2 mm, and the obtained ground product is converted with a thermoplastic material into the pigmented thermoplastic material during a second step, making use of a flush process performed in a kneading device or extruder, at increased temperature and a pH value of initially 7 or less.
