PAD FOR INSULATION OF IMPACT NOISE BASED ON WOOD-SYNTHETIC COMPOSITE MATERIAL Russian patent published in 2019 - IPC C04B26/04 C04B16/02 E04F15/10 E04F15/20 E04B1/82 E04C2/10 B29C70/18 C04B111/50 C04B111/52 

FIELD: construction.

SUBSTANCE: present invention relates to a pad for insulation of impact noise based on wood-synthetic composite material. Pad for insulation of impact noise based on wood-synthetic composite material is characterized by the fact that synthetic material in wood-synthetic composite material is used in form of thermoplastic synthetic material, in particular in form of thermoplastic granulated materials or synthetic fibres, wherein the mixture of wood particles and synthetic material has a mixture ratio of 90 wt. % of wood particles/10 wt. % of synthetic material to 20 wt. % of wood particles/80 wt. % of synthetic material, wherein pad to isolate percussion noise has thickness of 2.5 mm and pad for insulation of impact noise is made folded in reverse direction. Invention is developed in dependent items of the formula.

EFFECT: technical result is reduction of thickness with increase in strength and improvement of elasticity.
