METHOD OF PROCESSING POLYMER WASTES AND GLASS BREAKAGE WITH OBTAINING FACING AND FINISHING MATERIALS Russian patent published in 2019 - IPC C04B14/22 C04B18/20 C04B26/02 C04B40/02 C04B111/20 

FIELD: construction.

SUBSTANCE: invention relates to the field of composite building materials and can be used for cladding and finishing the outer and inner walls of buildings and structures. In the method of processing polymeric wastes with obtaining facing and finishing materials, preliminary mixing of wastes of unplasticized polyvinyl chloride in the amount of 10–20 wt.% is carried out with technical solvent – methylene chloride technical at a ratio of from 1:1.5 to 1:2.5, the resulting solution of the binder is mixed with a filler – glass breakage with a particle size of not more than 0.63 mm, along with pressing the product at a specific pressure of 8 MPa, followed by temperature treatment under the following conditions: temperature rise rate 20 °C/min; duration of exposure at the boiling point of the solvent 45–90 minutes.

EFFECT: improving the strength characteristics, reducing the duration and energy intensity of the production process.
