A heat-insulating and sound-insulating composite material and its production process

Abstract

The invention discloses a heat insulation and sound insulation composite material and a production technology thereof. The composite material is used between 'a concrete protective layer or a decorative finish layer' and 'a ground concrete structural layer or a wall surface'; the composite material is formed by compounding two layers or more than two layers of materials; the upper layer of the heat insulation and sound insulation composite material is formed by a coiled material or a sheet material which is made from one or more of rubber, a high polymer material, polyvinyl chloride (PVC), metal or a fiber raw material; the lower layer of the heat insulation and sound insulation composite material is formed by a coiled material or a sheet material which is made from one or more of foam polyurethane, polyester fiber cotton, sponge, an expandable polystyrene (EPS) board, an extruded polystyrene (XPS) board, foaming rubber or foaming PVC. Furthermore, the invention also discloses the production technology of the composite material. The composite material is good in effects of heat insulation and sound insulation, simple in construction technology and fewer in construction quality control points.

Description

technical field [0001] The invention relates to a building material, in particular to a heat-insulating and sound-insulating composite material and a production process. Background technique [0002] With the improvement of people's material living standards, the requirements for space comfort in daily life are getting higher and higher, especially for the acoustic environment and the temperature of the space environment. The requirements for the acoustic environment are mainly reflected in noise reduction, which belongs to the category of environmental protection. The maintenance of space ambient temperature belongs to the category of energy saving. Energy saving and environmental protection are also two key concerns in the world today. High-efficiency, new, green energy-saving and environment-friendly products have become one of the key research directions of scientists from all over the world. Similar products before the development of this product generally have a single...

Problems solved by technology

Similar products before the development of this product generally have a single function from design to final use, either only considering the issue of energy saving, or only considering the issue of sound insulation. Materials and processes are used to complete the heat insulation, which requires one material and process to complete. This means that multiple process constructions are carried out in the same space to meet the requirements of noise reduction and heat insulation. Multiple constructions are not just construction time. Long, and the construction process is relatively complicated, there are many quality control points, the project quality is not easy to be guaranteed, and the management cost and project cost are relatively high
