Heat-insulation and sound-insulation composite plate

Abstract

The invention discloses a heat-insulation and sound-insulation composite plate which is composed of two layers of heat insulation plates and two layers of sound insulation plates arranged between the heat insulation plates, wherein the heat insulation plates and the sound insulation plates are bonded with a sound insulation adhesive, a layer of wooden moisture-proof plate adheres to the outer side of each heat insulation plate with glue, the heat insulation plates are made of any one or two of polyethylene foam plates, polyurethane foam plates and polystyrene foam plates, the sound insulation plates are rock wool plates, and the sound insulation adhesive is prepared in the mode that 120 parts of cement, 30 parts of expanded perlite and 10 parts of silicon dioxide are mixed evenly, then 100 parts of 60-65 DEG C hot water is added, and then stirring is conducted to obtain the sound insulation adhesive. The heat-insulation and sound-insulation composite plate is good in sound insulation effect and heat insulation effect, simple in production technology and resistant to fire, and dual-sound-insulation is achieved by the sound insulation layers.

Description

technical field [0001] The invention relates to a heat-insulating and sound-insulating composite board, which belongs to the technical field of wood-plastic boards for building decoration. Background technique [0002] With the society's requirements for energy saving and emission reduction, all walks of life are looking for ways to save energy and reduce emissions. For northerners, winter is the season that consumes the most energy. Because they need to keep warm and keep out the cold, they use a lot of fuel, and only continuous burning throughout the day can keep the house warm, which causes a waste of fuel. Here Under such circumstances, insulation boards came into being. The current insulation boards are only suitable for family houses, not for factory buildings, because the environment in the factory buildings is generally not good, and some companies generally use steel plate frames for factory buildings, which are particularly cold in winter, and the working environm...

AI Technical Summary

Problems solved by technology

The current insulation boards are only suitable for family houses, not for factory buildings, because the environment in the factory buildings is generally not good, and some companies generally use steel plate frames for factory buildings, which are particularly cold in winter, and the working environment of workers very bad

Today's enterprises are generally in continuous production 24 hours a day, and the rotation of the machine is transmitted farther and louder at night, thus affecting the normal life of nearby residents

At present, various enterprises have not taken effective sound insulation measures, so they can only build factories away from residents, but even so, noise is still a major factor affecting residents' lives

And so far no new sound insulation measures have been introduced to change the existing situation
