CONSTRUCTIVE MEMBER OF MULTIPLE-FUNCTION COATING Russian patent published in 1998 - IPC

FIELD: acoustic and temperature insulation for industry and transport. SUBSTANCE: device has at least two adjacent layers of rubber-like material which has pores with axial symmetry. Pores in layer which is adjacent to protected surface are located in coaxial with pores of layer, which is spaced from protected surface, and are fully filled with adhesive material. Pores of layer which is spaced from protected surface are also partly filled with adhesive material. Adhesive fills at least 0.05 of volume pores but is less than 0.2 of this volume. Diameter of pores which are fully filled with adhesive material is not less than 0.3 of thickness of this layer but is less than 0.8 of diameter of corresponding coaxial pores. EFFECT: increased static and dynamic forces which affect coating. 1 dwg
