Description

Technical Field

[0001] This utility model relates to the field of thermal insulation and sound insulation materials, specifically to a thermal insulation and sound insulation board for underfloor heating installation. Background Technology

[0002] With the increasing demand for comfortable, energy-efficient, and space-efficient modern living, underfloor heating is being installed in more and more buildings. Currently, the most commonly installed type of underfloor heating is water-based, which uses hot water as the heat medium. The hot water circulates through pipes buried under the floor, heating the floor and then dissipating heat into the room through radiation and convection.

[0003] To reduce energy consumption when using underfloor heating, a good thermal insulation environment is needed between the underfloor heating pipes and the floor slab to prevent heat loss through conduction. Currently, underfloor heating systems often use resin foam materials as the insulation between the pipes and the floor slab. While these materials provide some insulation, significant heat loss still occurs, and their insulation performance needs further improvement. Additionally, the sound insulation and vibration reduction performance of the floor slab is also a concern, as existing underfloor heating systems often exhibit poor sound insulation and vibration reduction properties. Therefore, a thermal insulation and soundproofing board for underfloor heating systems is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a heat insulation and soundproofing board for underfloor heating installation, so as to solve the problems existing in the prior art mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thermal insulation and soundproofing board for underfloor heating includes a vacuum insulation board, a thermal insulation mortar protective shell, and a sound insulation layer. The lower end face of the thermal insulation mortar protective shell is provided with a groove, and the vacuum insulation board is installed in the groove.

[0007] The bottom surface of the thermal insulation mortar protective shell is bonded with a sound insulation layer, which is used for sound insulation and noise reduction of the floor slab. The upper surface of the thermal insulation mortar protective shell is provided with a limiting structure for limiting the laying of underfloor heating water pipes.

[0008] Preferably, the sound insulation layer is a high-density polyvinyl chloride board.

[0009] Preferably, the sound insulation layer is bonded and fixed to the lower end face of the thermal insulation slurry protective shell using a two-component adhesive.

[0010] Preferably, the limiting structure is a groove, which is formed on the thermal insulation grout protective shell after the thermal insulation grout has cured.

[0011] Preferably, the vacuum insulation panel is made by vacuum sealing a core material covered with a high-barrier film.

[0012] Preferably, after the underfloor heating pipes are laid on the limiting structure, the axial distance between two adjacent underfloor heating pipes is set to 180-220mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model combines a vacuum insulation board with a thermal insulation mortar protective shell to form an insulation board for laying underfloor heating. A limiting structure is integrally formed on the thermal insulation mortar protective shell. While facilitating the laying of underfloor heating pipes, it effectively improves the thermal insulation performance of the entire building floor and reduces the energy consumption of underfloor heating. Furthermore, by bonding a sound insulation layer to the bottom of the thermal insulation mortar protective shell, the sound insulation and noise reduction performance of the building floor is further improved.

[0021] A thermal insulation and soundproofing board for underfloor heating includes a vacuum insulation board 1, a thermal insulation mortar protective shell 2, and a sound insulation enhancement layer 3. The vacuum insulation board 1 is made by vacuum sealing a core material covered with a high-barrier film. The core material is made of silica or glass fiber. The high-barrier film includes an outer film, a middle film, and an inner film arranged sequentially from the outside to the inside.

[0025] The lower end face of the thermal insulation mortar protective shell 2 is provided with a groove, and the vacuum insulation panel 1 is installed in the groove. The thermal insulation mortar protective shell 2 is a mortar made of flame-retardant expandable polystyrene foam particles, hydraulic inorganic cementitious materials, polymers, additives, etc. The thermal insulation mortar protective shell 2 protects the vacuum insulation panel 1, preventing damage and failure of the high-barrier membrane. In addition, the thermal insulation mortar protective shell 2 has higher strength than traditional resin foam materials, preventing large deformation after the floor is laid on it, and extending the service life of the floor. The performance indicators of the thermal insulation mortar protective shell 2 are shown in the table below:
