Spliced type polyurethane heat insulation and heat preservation roof board

Abstract

The invention discloses a spliced ​​polyurethane roof heat insulation board, the structure of which comprises a cold-rolled plate, a zinc coating layer, a chemical conversion layer, a primary coating layer, a fine coating layer, and a polyurethane foam storage plate. The cold-rolled plate The surface is rectangular, and the right side of the upper end is provided with a zinc-coated layer. The upper surface of the zinc-coated layer is rectangular, and the cut surface is a rectangle. The cut surface of the cold-rolled sheet is a rectangle with a length of 6-7cm. Interference fit is used for movable connection, the upper right side of the zinc coating layer is provided with a chemical conversion layer, and the chemical conversion layer is connected with the chemical conversion layer by a clearance fit. The beneficial effect of the present invention is that a polyurethane foam storage plate is provided. The heat energy received by the plate is stored in the energy storage plate, and the heat energy is released by the transmission plate, which makes the equipment keep warm quickly, solves the problem of slow heat insulation efficiency, and avoids the reduction of equipment utilization rate.

Description

technical field [0001] The invention relates to a spliced ​​polyurethane roof heat insulation and heat preservation board, which belongs to the field of house roof heat insulation materials. Background technique [0002] The northern part of our country is cold in winter. In order to ensure that the temperature inside the room in winter can meet the requirements of use and the needs of building energy conservation, an insulation layer should be installed on the roof. [0003] The prior art discloses a spliced ​​polyurethane roof heat insulation board whose application number is CN201020519152.X. Its structure includes a rectangular decorative board shell filled with polyurethane foam. Among the four sides of the shell, the opposite two sides are respectively provided with tenons and grooves which can be fitted and embedded, and the four corners of the decorative board shell are provided with cut corners, and the cut corners are provided with clamping holes . Compared with ...
