Title:
METHOD OF MAKING ROTATIONALLY MOULDED PARTS HAVING NANO-PARTICLE REINFORCEMENT
Document Type and Number:
WIPO Patent Application WO2000037241
Kind Code:
A9
Abstract:
A method of producing reinforced articles comprises (a) preparing a powder composition of at least one thermoplastic and about 2 % to about 15 % by volume reinforcing particles. The reinforcing particles are substantially uniformly dispersed in the thermoplastic. At least 50 % of the reinforcing particles are less than about 20 layers thick, the layers of the reinforcing particles having a unit thickness of between about 0.7 nm - 1.2 nm; (b) heating the powder into a molten material; (c) rotating the molten material in a mold cavity so that the molten material conforms to the surfaces of the mold cavity, the molten material having substantially the same uniformity of dispersion of the reinforcing particles therein in comparison with the uniformity of dispersion of the reinforcing particles in the thermoplastic powder; and (d) cooling the molten material to form a reinforced article.
