Soundproof heat-preservation composite pad

Abstract

The invention discloses a soundproof heat-preservation composite pad. The soundproof heat-preservation composite pad comprises a surface layer, a heat-preservation layer, a supporting layer, a shock absorption layer and a water tank, wherein the surface layer a felt; the heat-preservation layer is laid on the lower layer of the surface layer, and the heat-preservation layer is a mixing layer of silicon dioxide aerogel and a nano coating agent; the supporting layer is laid on the lower layer of the heat-preservation layer, the supporting layer is formed by splicing a plurality of stainless steel pipes; the shock absorbing layer is laid on the lower layer of the supporting layer, and the shock absorption layer is an electronic cross-linked polyethylene material; and the water tank is laid onthe lower layer of the shock absorption layer, and connected with a drain pipe, and permeated liquid is discharged to the drain pipe. According to the soundproof heat-preservation composite pad, theeffect of heat preservation is increased, thermal conductivity is low, and fireproof effect is very good, inflaming retarding can be carried out effectively in the case of combustion, and the liquid can penetrate through holes; and the sound can be more thoroughly prevented from being transmitted, and the holes are formed to prevent depressions or deformation.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a sound-insulating and heat-insulating composite pad. Background technique [0002] Nowadays, people have higher and higher requirements for the quality of life at home. The improvement of impact sound and thermal insulation performance of floors and floors has become an inevitable requirement for buildings. The materials currently used for impact sound improvement and thermal insulation on floors are mainly: [0003] Extruded polystyrene board, made of polystyrene, does not absorb water, and has a low thermal conductivity, specifically ≥0.028w / m·k. [0004] XPE or IXPE material, made of low-density polyethylene resin plus cross-linking agent and foaming agent after high-temperature continuous foaming, has a certain improvement effect on impact sound, but the effect of floor insulation is poor, thermal conductivity ≥ 0.032w / m·k.

Problems solved by technology

[0004] XPE or IXPE material, made of low-density polyethylene resin plus cross-linking agent and foaming agent after high-temperature continuous foaming, has a certain improvement effect on impact sound, but the effect of floor insulation is poor, thermal conductivity ≥ 0.032w / m·k

[0005] 3. Ceramsite concrete, which is made of cementitious materials and lightweight aggregates, has good heat resistance and fire resistance, but it cannot improve the impact sound of the floor. It has high requirements for construction technology and is prone to surface cracking Phenomenon

To sum up, the existing technology leads to the use of existing building materials in the project of improving floor impact sound and thermal insulation performance, which has high cost, complicated construction technology, insufficient technical parameter requirements, and prone to cracking of the surface layer.
