Problems solved by technology

Comparing these two different types of thermal insulation materials for thermal insulation decorative panels, although the former has good flame retardancy, it has a high water absorption rate and needs to be waterproofed; secondly, rock wool has low strength and is not suitable for use in this way. Materials with heavy weight per unit area such as stone are used as thermal insulation decorative panels for facing; thirdly, rock wool has a high thermal conductivity, and compared with polyurethane rigid foam, a thicker rock wool layer is required to achieve the corresponding thermal insulation effect; In terms of flame retardant performance, the effect is average, but it makes up for the defects of high water absorption, low strength and high thermal conductivity of rock wool
In addition, during the construction of these two integrated boards, rock wool and polyurethane need to be treated separately on the interface before they can be mounted on the wall, and it is difficult to achieve continuous production by using the ordinary paste method, and the production efficiency, cost and energy consumption are still very large. room for improvement

Embodiment 1

[0038] The reference of the polyurethane modified rock wool thermal insulation decorative board in this embodiment figure 1 . Including the decorative surface material 6 for decoration and fire prevention, the rock wool 4 that is applied on the back of the decorative surface material and combined with the decorative surface material, and the polyurethane that combines the decorative surface material 6, rock wool 4 and interface coil material 8 into one The foam layer 13, and the interface coil 8 attached to the other side of the polyurethane foam layer 13, the decorative surface material 6 adopts a thin stone veneer, and the thickness of the rock wool 4 is 5cm. The specific operation steps of the production process are:

[0039]Adopt a continuous production line consisting of foaming machine 1, conveying track II3, preliminary bonding mechanism, conveying track I16, double track laminating machine mechanism, uncoiler 9, and pouring mechanism, and set conveying track II3, uncoi...

Embodiment 2

[0041] The polyurethane modified rock wool insulation decorative board of this embodiment refers to the attached figure 2 . The difference between this embodiment and Embodiment 1 is that the decorative surface material 6 adopts an acrylic veneer, and the back of the acrylic board is compounded with three rock wool 4, the thickness of the rock wool 4 is 6cm, and the interval between each rock wool is 3cm. The specific operation steps of the process are:

[0042] Set the linkage speed of conveyor track II3, conveyor track I16, double track laminator mechanism, and uncoiler 9 to 4.5m / min, place a 1.2m×0.6m acrylic veneer on the conveyor track I16, and place three 1 m Rock wool 4 × 0.15m is placed on the conveyor belt II 3, and the pressure of the gun head 7 of the glue spraying machine is adjusted to 16MPa, and the flow rate is 208g / s. In the first process, the adhesive is evenly poured on the acrylic veneer to complete the preliminary bonding of the rock wool 4 and the acryl...

Embodiment 3

[0044] The polyurethane modified rock wool thermal insulation decorative board of this embodiment differs from that of Embodiment 1 in that the decorative surface material 6 is made of flexible stone, and the thickness of the rock wool 4 is 10 cm. The specific operation steps of the production process are as follows:

[0045] Set the linkage speed of conveying crawler II3, conveying crawler I16, double crawler lamination mechanism, and coil uncoiling mechanism 9 to 10m / min, place a 0.9m×0.73m flexible stone on the conveying crawler I16, and place a 0.75m×0.6 M rock wool 4 is placed on the conveyor belt II 3, and the pressure of the gun head 7 of the glue spraying machine is adjusted to 10MPa, and the flow rate is 500g / s. In the first process, the adhesive is evenly poured on the flexible stone to complete the preliminary bonding of the rock wool 4 and the flexible stone. In the second process, the polyurethane composite material with a material temperature of 40 ° C is evenly p...

Abstract

A polyurethane modified rock wool thermal insulation decorative board and its continuous production equipment and continuous production method. It includes the decorative surface material for decoration and fire prevention. One or more pieces of rock wool are arranged on one side of the decorative surface material. The decorative panel and the rock wool are combined into one through the polyurethane foam layer. Interface membrane with one-piece structure. The polyurethane modified rock wool thermal insulation decorative board produced by the present invention integrates the good flame retardant effect of rock wool and the excellent thermal insulation, waterproof and mechanical properties of rigid polyurethane foam, with stable and controllable quality, safe and reliable performance, and excellent craftsmanship. It is simple and easy to implement, greatly improves the production efficiency of the product, shortens the construction period, and the interface reinforced coil layer has a good affinity with the cement, so no interface treatment is required during construction.

Description

technical field [0001] The invention relates to a polyurethane modified rock wool thermal insulation decorative board (PRR board for short) and its continuous production equipment and continuous production method, belonging to the technical field of building materials. Background technique [0002] As a traditional thermal insulation material, rock wool has Class A flame retardant properties and is widely used in the field of external wall insulation. Polyurethane rigid foam, as an emerging material with the best thermal insulation effect, has great development prospects in the field of external wall insulation. The patent number is CN201220537075.X, and the patent name is: New Wall Rock Wool Thermal Insulation and Decoration Integrated Board, which provides a new wall rock wool thermal insulation and decoration integrated board, including a thermal insulation layer and a decorative layer. The thermal insulation layer is a rock wool Cotton insulation board, the decorative la...
