Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation and decorative integrated panels, in particular to a thermal insulation and decorative integrated panel made of polyvinyl chloride foam material. Background Art

[0002] Energy-saving exterior wall decorative integrated panels are a new type of integrated insulation material developed in recent years. They are factory-processed and composited from thermal insulation materials and decorative panels. They are primarily used for exterior wall energy-saving decoration and renovation of new, renovated, expanded, and existing civil and public buildings (gymnasiums, libraries, school and hospital office buildings, villas, and other structures). Their primary functions include architectural decoration, thermal insulation, energy saving, and heat and sound insulation. While other new insulation materials are emerging, energy-saving decorative insulation materials, with their permanence, safety, and high reliability, are gaining increasing importance in low-heat insulation, moisture-proofing, and sound absorption. Rock wool strips, a Class A fireproof material, are widely used in integrated insulation decorative panels. However, due to the thermal conductivity of rock wool strips and the design requirements for building energy conservation, the unit area mass of rock wool composite insulation and decorative integrated panels often reaches or even exceeds the industry standard maximum of 30 kg / m2. Furthermore, due to the loose structure of rock wool itself, it is difficult to significantly improve the bonding strength of the insulation decorative panels after they are made. Its cohesive strength will be significantly reduced when exposed to water, leaving certain safety hazards for the rock wool composite insulation decorative panel exterior wall insulation system. Another type of insulation decorative integrated panel insulation material uses polystyrene board and foamed polyurethane board, which has a lower density, lighter weight, and better insulation performance, but has poor flame retardancy and is a Class B fireproof material. Used for exterior wall insulation and decoration, it poses a fire risk.

[0003] To address the above-mentioned issues, the invention patent with publication number CN109629786 A discloses an insulating decorative integrated panel infused with polyurethane and composited with rock wool strips. The integrated panel includes a decorative panel, rock wool strips, and a perforated backing plate. One side of the rock wool strips is bonded to the back of the decorative panel, and the other side is bonded to the perforated backing plate. The rock wool strips are arranged between the decorative panel and the perforated backing plate according to a predetermined position and a cavity is reserved. The cavity is filled with a flame-retardant polyurethane foam. Although this insulating decorative integrated panel uses low-density polyurethane and rock wool strips to composite, which reduces weight to a certain extent, due to the low compressive strength of the rock wool, the back side still needs to be composited with a perforated backing plate. This decorative integrated panel has a three-layer structure and is still relatively heavy. In addition, the rock wool strips are arranged between the decorative panel and the perforated backing plate according to a predetermined position and a cavity is reserved. The polyurethane is composited in the cavity, which makes the production process more complicated and increases production costs. Therefore, it is necessary to improve it. On the basis of reducing the unit area mass of the Class A fireproof insulation decorative panels and the thermal conductivity of the system, the bonding strength of the system's insulation materials should be improved so that it can better adapt to the application of building exterior walls. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides a polyvinyl chloride foam material thermal insulation and decorative integrated board with low mass per unit area, high flame retardancy and good thermal insulation performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polyvinyl chloride foam thermal insulation decorative integrated panel, comprising an insulation layer and a finishing layer. The insulation layer is glued to the back of the finishing layer. The finishing layer is an inorganic plate or a metal plate, and the insulation layer is polyvinyl chloride foam. Anchoring structures are provided on the side of the finishing layer of the thermal insulation decorative integrated panel, and a dovetail groove is provided on the back of the thermal insulation layer to further enhance the bonding strength with the wall. During installation, a bonding and anchoring method is adopted. First, bonding mortar is applied to the back of the thermal insulation decorative integrated panel. Then, the thermal insulation decorative integrated panel is fixed to the wall using the integrated panel anchors through the anchoring members provided on the side of the finishing layer.

[0006] Wherein said polyvinyl chloride insulation layer:

[0007] Apparent (bulk) density ≤ 100kg / m 3 ,

[0008] Thermal conductivity ≤ 0.035W / (m·K),

[0009] Compression strength ≥0.2MP,

[0010] As a further improvement of the above, the anchoring structure arranged on the side of the finishing layer of the thermal insulation decorative integrated panel is an anchoring groove, and the thickness of the lower edge of the anchoring groove is not less than 3 mm from the back of the finishing layer. During installation, the bracket part of the integrated panel anchor is installed in the anchoring groove, and the other end is fixed to the wall, thereby fixing the thermal insulation decorative integrated panel to the wall.

[0011] As a further improvement of the above, the anchoring groove is a side ring groove on the finishing layer of the thermal insulation decorative integrated board, which is an anchoring groove with a length of not less than 100 mm on the side of the finishing layer of the thermal insulation decorative integrated board, and the number of anchoring grooves on the thermal insulation decorative integrated board is not less than 6 / square meter.

[0012] As another improvement of the above, the anchoring structure on the finishing layer of the thermal insulation decorative integrated panel is a stepped full-length step opened along the upper edge of the finishing layer of the thermal insulation decorative panel, and the thickness of the remaining layer of the step is not less than 3 mm. During installation, the bracket part of the integrated panel anchor is installed on the finishing layer step, and the other end is fixed to the wall, thereby fixing the thermal insulation decorative integrated panel to the wall.

[0013] The utility model has the following beneficial effects: the thermal insulation layer adopts polyvinyl chloride foam material, which has low apparent density and low thermal conductivity, and the thermal insulation performance is effectively improved, thereby making the thermal insulation decorative integrated panel lighter; due to the high compression strength of the polyvinyl chloride foam material, the back plate of the thermal insulation decorative integrated panel is omitted, the weight is further reduced, and the cost is also reduced; through the anchoring structure and the dovetail groove on the back of the thermal insulation layer, the bonding strength between the integrated panel and the wall is further enhanced.
