Composite multi-layer heat preservation and sound insulation structure

Abstract

The invention discloses a composite multi-layer heat preservation and sound insulation structure which comprises a thermal reflection layer, a first weaved cloth layer, a melamine foam layer, a second weaved cloth layer and a metal plate damping structure, wherein the thermal reflection layer is arranged on the surface of one end of the first weaved cloth layer and is compounded with the first weaved cloth layer; the melamine foam layer is arranged the first weaved cloth layer and the second weaved cloth layer; and the metal plate damping structure is arranged at the lower end of the melamine foam layer. The composite multi-layer heat preservation and sound insulation structure is formed by compounding multi-layer materials, and has relatively good heat preservation effect and sound insulation performance and good flame retardant property; and the flame retardant property of the melamine foam layer can reach the B1 level. A nonflammable material is coated with the materials of the thermal reflection layer, the woven cloth layers and the like, so that the overall thermal insulation property is greatly improved; the composite multi-layer heat preservation and sound insulation structure is convenient and fast to construct, simple and convenient in structure and small in thickness; time and labor are saved; the total thickness of the structure is only 10-100mm and lower than that of a traditional structure; and the composite multi-layer heat preservation sound insulation structure has relatively good heat preservation performance and sound insulation performance.

Description

technical field [0001] The invention relates to a composite multilayer thermal insulation and sound insulation structure, which belongs to the field of building thermal insulation and sound insulation. Background technique [0002] In the general environment of the global low-carbon economy, the development of environmental protection and energy-saving materials is one of the key links. In recent years, countries all over the world are facing serious energy problems. More than 1.3 billion tons, accounting for nearly 10% of the world's energy consumption, ranking second in the world. At the same time, environmental noise and vibration pollution is a kind of physical pollution, which will affect human physiology and psychology, leading to people's environmental complaints about noise. It even triggers radical behavior and affects social harmony. At present, building insulation and sound insulation materials such as rock wool, glass wool, slag wool and other related materials p...
