Multifunctional sound-insulating and vibration-damping composite material for building floors, and production technology thereof

Abstract

The invention discloses a multifunctional sound-insulating and vibration-damping composite material for building floors. The composite material comprises a base layer and a soft elastic vibration-damping layer arranged on the surface of the base layer, a hollow glass bead suspension is arranged between the base layer and the vibration-damping layer, and the hollow glass bead suspension layer is formed through uniformly curing a plurality of hollow glass beads in an adhesive layer formed by an adhesive. The hollow glass beads contain nitrogen, carbon dioxide and other gases, so the hollow glassbeads have the advantages of small density, light weight, strong adhesion, easiness in coating, low thermal conductivity and stable physical and chemical properties, and can be very easily dispersedand suspended in glues, coatings and other organic material to form an excellent sound-insulation and thermal-insulation layer.

Description

Technical field: [0001] The invention belongs to the technical field of new building materials, and in particular relates to a multifunctional sound-insulating and vibration-damping composite material for building floors, and also relates to a production process of the material. Background technique: [0002] As we all know, sound comes from the vibration of objects, and the vibration propagates in the air to form a sound wave, and when the sound wave is incident on the wall or the floor, it will cause the wall or the floor to vibrate and radiate outward. Noise is the sound produced when the sounding body vibrates irregularly. In daily life, the most common behaviors in daily life are that the upstairs residents walk (especially hard heels such as high heels), the children play and run, and the household moves, etc., give the floor an impact force, which is enough to make the floor slab produce vibration. If the vibration reduction effect of the floor is not good, the soun...

Problems solved by technology

[0004] At present, most of the materials used for sound insulation and vibration reduction on the ground of building floors in my country have single functions. The present invention provides a material that can effectively solve the noise transmission interference on the ground of the building floor, reduce heat transfer and loss between households, and improve fire protection at the same time.
