Abstract

Description
Technical Field
The invention relates to the technical field of fireproof plate production, in particular to a production process of a double-track serial special fireproof composite plate.
Background
In the general sandwich board production process, the metal-surface polyurethane or rock wool sandwich board can be manufactured by only one continuous production line with double tracks. The same is true for equipment at home and abroad. The product is as follows: the surface material is a metal plate (color steel and stainless steel type aluminum plate), the core material is polyurethane hard foam or rock wool, and the surface material is generally used for heat preservation of a cold storage and an outer wall of an industrial factory building.
Because polyurethane rigid foam belongs to an organic material, the polyurethane rigid foam can burn, has poor fireproof performance, and can more effectively prevent fire and meet the requirements of national building design fireproof standards. We define this plate shape as: special metal surface fireproof heat-insulating composite board. The structure is as follows: metal surface + rock wool board/plasterboard + polyurethane rigid foam + rock wool board/plasterboard + metal surface.
The plate type of the structure is that the inner wall of the metal surface of the common sandwich plate is re-adhered with the rock wool plate or the gypsum plate as the fireproof layer of the core material PU, so that the production process difficulty is increased, the production cannot be carried out on the common sandwich plate continuous production line, but the products of the structure are not produced at home and abroad, and meanwhile, no equipment can produce the products at home and abroad, so that the products are not introduced into the market all the time.
