Polyurethane modified rock wool heat-insulation decoration board and continuous production device and method thereof

Abstract

The invention provides a polyurethane modified rock wool heat-insulation decoration board and a continuous production device and method thereof. The polyurethane modified rock wool heat-insulation decoration board comprises a decoration body and a decoration face material having the fireproof effect, wherein one or more pieces of spaced rock wool are arranged on one side of the decoration face material, the decoration face material and the rock wool are compounded through a polyurethane foam layer to form a whole, and an interface coiled material with an integral structure is arranged on one side of the polyurethane foam layer. The polyurethane modified rock wool heat-insulation decoration board integrates the advantages of the good flame retardant effect of the rock wool, excellent heat insulation, water proofing, mechanical performance of hard foam polyurethane and the like, the quality is stable and controllable, the performance is safe and reliable, a process is simple, convenient and easy to operate, the production efficiency of products is greatly improved, a construction period is shortened, an interface reinforcing coiled material layer and cement have good affinity, and interface treatment on the decoration board is not needed during construction.

Description

Technical field [0001] The invention relates to a polyurethane modified rock wool thermal insulation decorative board (PRR board for short) and continuous production equipment and a continuous production method thereof, 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 thermal insulation. As a new material with the best thermal insulation effect, rock wool has great development prospects in the field of external wall thermal insulation. The patent number is CN201220537075.X, and the patent name is: a new type of wall rock wool thermal insulation and decoration integrated board, providing a new wall rock wool thermal insulation and decoration integrated board, including an insulation layer and a decorative layer, the insulation layer is rock Cotton thermal insulation board, the decorative layer is cement...

AI Technical Summary

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
