Abstract

The invention belongs to the field of fire-proof heat insulating materials for buildings, and discloses an insulating fireproof composite board for a wall body. The insulating fireproof composite board comprises a gypsum board on the lower layer and surface cover paper on the upper layer, wherein the gypsum board and the surface cover paper are bonded through a binding material. The insulating fireproof composite board has better fire resistance and heat preservation, has wide raw material sources, is simple in preparation method, and has brighter market prospect.

Description

[0001] technical field [0002] The invention belongs to the field of building materials, and in particular relates to a thermal insulation and fireproof composite board for walls. Background technique [0003] Fire refers to the disaster caused by burning out of control in time and space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. Human beings can use and control fire, which is an important symbol of civilization progress. Therefore, the history of human use of fire and the history of fighting against fire go hand in hand. While using fire, people constantly summarize the law of fire occurrence and minimize fire and its harm to human beings. At present, common fires are building fires, which seriously endanger human life safety and property safety. How to provide the fire performance of building materials is a problem that needs to be solved. [0004] In the field of constru...
