Abstract

L'invention concerne un procédé pour incorporer une poudre de talc dans une matière, en particulier matière thermoplastique. Ce procédé consiste (a) à mélanger la poudre de talc avec de l'eau et un polyéthylène glycol, un polypropylène glycol ou un copolymère de ces composés, (b) à presser le mélange à travers des filières et à le tronçonner de façon à obtenir des granulés de dimension moyenne supérieure à celle des grains de la poudre initiale, (c) à incorporer dans la matière le produit obtenu, (d) et à procéder à une action mécanique de dispersion de façon à désagréger les granulés et à libérer et répartir dans la masse les grains de la poudre initiale. L'invention permet d'incorporer des poudres de talc de faible granulométrie dans des matières notamment thermoplastiques, sans conduire aux difficultés pratiques d'incorporation rencontrées avec les poudres de faible granulométrie.The invention relates to a method for incorporating talcum powder into a material, in particular a thermoplastic material. This process consists of (a) mixing the talcum powder with water and a polyethylene glycol, a polypropylene glycol or a copolymer of these compounds, (b) pressing the mixture through dies and cutting it so as to obtaining granules of average size greater than that of the grains of the initial powder, (c) incorporating into the material the product obtained, (d) and carrying out a mechanical dispersing action so as to disintegrate the granules and to release and distribute the grains of the initial powder in the mass. The invention makes it possible to incorporate talcum powders of small particle size in materials, in particular thermoplastics, without leading to the practical difficulties of incorporation encountered with powders of small particle size.
