Polyurethane composite thermal insulation board, manufacturing method and application of the same

Abstract

The invention provides a polyurethane compound heated board and a manufacturing method and application, which relates to a heated board and supplies a polyurethane compound heated board that has good heat-insulating effect, high fire-fighting and flame-retardant performance, convenient using performance and high constructing efficiency and the manufacturing method and the application. The invention includes a polyurethane rigid foam insulating layer, a bonding layer and an inorganic material composite board; the bonding layer is arranged between the polyurethane rigid foam insulating layer and the inorganic material composite board; the thickness of the polyurethane rigid foam insulating layer is 20-80mm and the thickness of the inorganic material composite plate is 3-10mm. The inorganic material composite board can be continuously produced for further use; an adhesive treatment agent is coated on the inorganic material composite board; polyhydric alcohol combination material and isocyanate combination material are added into the continuous production line for mixed foaming and curing to obtain the polyurethane compound heated board; the mass ratio of the polyhydric alcohol combination material and the isocyanate is 100:95-160.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a polyurethane composite thermal insulation board mainly used in buildings and its manufacturing method and application. Background technique [0002] Due to the high energy consumption of buildings, serious energy waste is a very common problem. Therefore, building energy conservation is a direct and inexpensive systematic project to alleviate energy shortages, improve environmental conditions, reduce environmental pollution, and promote sustainable economic development. Currently used building insulation materials, such as extruded boards, polystyrene boards, polystyrene particles, polyethylene high-foaming and other foam materials, although light in weight and acceptable in thermal insulation effects, generally have the following disadvantages: 1) flammable , toxic smoke, poor temperature resistance; 2) poor water absorption, easy to mildew in a humid environment and cause the wal...

Problems solved by technology

Currently used building insulation materials, such as extruded boards, polystyrene boards, polystyrene particles, polyethylene high-foaming and other foam materials, although light in weight and acceptable in thermal insulation effects, generally have the following disadvantages: 1) flammable , toxic smoke, poor temperature resistance; 2) poor water absorption, easy to mildew in a humid environment and cause the wall to turn black; 3) when the wall is insulated, the bonding ability with the bonding material is poor, For example, it has poor adhesion to gypsum materials, cement mortar, etc., and a large number of nails and anchors are needed to fix it; 4) The construction period is long and the construction procedures are complicated; 5) It cannot be combined with inorganic materials, metals, and non-metals. and textile fibers for continuous one-time molding to produce composite panels (reference: ①Lin Yancheng, Preliminary Study on Rockwool External Wall Thermal Insulation Technology, China Building Thermal Insulation Information, 2007, 7:35; ②Yang Zongkun, Current building energy conservation in China should not be ignored Big Problems, China Building Thermal Insulation Information, 2007, 8:36; ③Tian Junxian, Yang Tongxing, Board-mounted Rigid Polyurethane Foam Insulation and Decoration Integrated Board and Exterior Wall External Thermal Insulation System Research, China Building Thermal Insulation Information, 2007, 10 : 32; ④Common quality problems and solutions of EPS polystyrene board external wall external insulation engineering, China Building Thermal Insulation Information, 2007, 11: 34; ⑤Xu Shiyuan, Weak links and countermeasures of commonly used external thermal insulation systems, Anhui Architecture)
