METHOD OF POLYMER WASTE PROCESSING ALLOWING TO OBTAIN CONSTRUCTION MATERIAL

FIELD: construction. ^ SUBSTANCE: invention uses unsorted waste of thermoplastic polymers LDPE, HDPE, in an amount of 10-50 % weight. The waste is crushed in advance and mixed with clay with a humidity of 8-12 %. The product is formed and pressed at a specific pressure of 10MPa. After that, heat tre...

Beschreibung
Zusammenfassung:	FIELD: construction. ^ SUBSTANCE: invention uses unsorted waste of thermoplastic polymers LDPE, HDPE, in an amount of 10-50 % weight. The waste is crushed in advance and mixed with clay with a humidity of 8-12 %. The product is formed and pressed at a specific pressure of 10MPa. After that, heat treatment is carried out at a temperature increase rate of 20°C/min. The duration of soaking at the polymer melting temperature is 90-180 minutes. ^ EFFECT: decreased energy consumption, simplification of method, and production of material with high technical performance. ^ 1 tbl
