Abstract

The invention belongs to the field of build environment-friendly materials and discloses a fireproof plaster board. The fireproof plaster board is formed by a plaster base body and protective paper; the plaster base body is arranged in the middle; the protective paper is arranged on the upper side and the lower side; binding materials are bound between the plaster base body and the protective paper. The produced fireproof plaster board has the advantages of being good in fire resistance, environmentally friendly and free of pollution, greatly improving the mechanical performance such as the compressive and bending strength and being good in market prospect.

Description

[0001] technical field [0002] The invention belongs to the field of building materials, and in particular relates to a fire-resistant paper-faced gypsum board and a preparation method thereof. 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] Gypsum bo...
