METHOD FOR MAKING POLYMER-BASE COMPOSITION MATERIALS Russian patent published in 2005 - IPC

FIELD: polymers, chemical technology.

SUBSTANCE: invention relates to technology for preparing composition materials. The claimed method involves mixing components, cold pressing blanks and their following caking. The caking procedure is carried out at temperature 280-350°C in closed form providing tension as result of heat expanding of a blank followed by cooling in the form. Before caking treatment with solution of fluorine-containing oligomer of sort "Foleoks" or "Epilam" is possible. The blank can be subjected for preliminary mechanical tension. Caking procedure can be carried out by two-step cycle in the closed form followed by annealing. Invention provides making articles made of composition materials based on high-viscous polymers with high strength and tribotechnical indices and positive properties by section, decreasing time of technological cycle in formation of articles, diminishing intensity of thermal oxidative destruction of material components. Invention can be used in machine engineering for making articles made of polymeric materials of different functional designation.

EFFECT: improved making articles.
