FIELD: shaping.
SUBSTANCE: invention relates to a method for producing high-molecular polymer-based compounds with the inclusion of liquid components, as well as to polymer articles produced from said compounds by means of extrusion. The technical result is achieved due to the method for producing a polymer article being characterised by the fact that for implementation thereof, the raw components in accordance with the specified composition are supplied into a plasticiser mixer wherein the raw materials are mixed by reciprocating movements and rotation of a four-bladed screw shaft and plasticised consecutively in three mixing area with a temperature mode in the areas of 40°C in area No. 1, 43°C in area No. 2, 38°C in area No. 3. The plasticised raw materials are compressed at the beginning of each mixing area. At the beginning of the third mixing area, distanced from the beginning of the effective length of the four-bladed screw shaft by L/D=5-6, wherein L is the length of the screw shaft, D is the diameter of the screw shaft under pressure, a liquid additive is supplied. After mixing the raw materials in the plasticiser extruder, they are directed into a dosing extruder, at the outlet whereof the melt is shaped into a finished article using a shaping extrusion head. The resulting shaped article is directed into a calibration bath for final shaping and cooling. Using a pulling roller apparatus installed at the output of the calibration bath, the finished article is directed for further processing.
EFFECT: ensured high content of the liquid component in the polymer raw materials at low melting points.
