Abstract

The invention discloses a fireproof color steel sandwich panel and a preparation method thereof, which belong to the field of color steel sandwich panels. Gridding cloth and anti-cracking balls A are combined and jointly formed in a phenolic foam board, and the phenolic sandwich panel with excellent heat preservation and fireproof performance is obtained; meanwhile, the tensile strength and compressive strength of the phenolic foam board are improved through the gridding cloth, the cracking and pulverization conditions of the phenolic foam board are reduced, then the overall performance is improved, cracks in the phenolic foam board with the cracking and fragmentation conditions can be repaired through the anti-cracking balls A, the fragmented phenolic foam board is bonded again, the phenolic foam board recovers a certain degree of strength performance, cracks are not prone to fragmentation, extension and expansion due to external force, the mechanical strength of the phenolic foam board is effectively enhanced, and therefore double guarantee measures are provided for the mechanical strength of the phenolic foam board.

Description

technical field [0001] The invention relates to the field of color steel sandwich panels, in particular to a fireproof color steel sandwich panel and a preparation method thereof. Background technique [0002] Color steel sandwich panel products are composed of two layers of formed metal panels (or other material panels) and a polymer heat insulation core that is directly foamed and matured in the middle of the panels. It has the characteristics of easy installation, light weight, environmental protection and high efficiency, and The closed-cell molecular structure used in the filling system can prevent condensation of water vapor. [0003] There are two types of color steel sandwich panels: metal panels and non-metal panels. There are six types of core materials: polystyrene sandwich panels, namely EPS sandwich panels (the most widely used variety in the market), extruded polystyrene sandwich panels, namely XPS sandwich panels, and rigid polyurethane sandwich panels. That...
