METHOD FOR MANUFACTURE OF PANELS OF "SANDWICH" TYPE WITH COMBINED HEAT INSULATION MATERIAL Russian patent published in 2009 - IPC E04C2/292 B32B5/22 B32B7/12 B30B5/06 

FIELD: construction.

SUBSTANCE: invention is related to construction branch of industry, in particular to manufacture of panels of "sandwich" type used as external envelopes of buildings and structures. Method includes turn of bar from previously cut mineral wool plate with width equal to panel thickness around its longitudinal axis by 90°. Bar is placed on delivery table. Additionally prior to cladding layer of mineral wool heat insulation material is treated by single-component glue along its whole width. Process of glue polymerisation is intensified by means of water supply into area of glue supply. Then carpet of mineral wool heat insulation material treated with glue is covered with foam polystyrene and passed through pressing rollers. After that combined carpet is sent to milling unit, where disk cutter is used to give required width to the carpet with strictly vertical longitudinal end perpendicular to panel plane. Then one bar with thickness equal to panel thickness is placed on both sides of carpet. Produced carpet is clad with galvanised metal on both sides.

EFFECT: creation of method for manufacture of "sandwich" type panels with combined heat insulation material, with higher heat insulation and strength characteristics.
