Abstract

The invention discloses a modified magnesite fireproof door core board as well as a preparation method and application thereof. The modified magnesite fireproof door core board comprises magnesium oxide, magnesium chloride, a compound modified additive, a compound foaming agent, titanium dioxide, silicon dioxide and an aqueous binder, and a mass ratio of the magnesium oxide to magnesium chloride to compound modified additive to compound foaming agent to titanium dioxide to silicon dioxide to aqueous binder is (39 to 54): (44 to 51): (0.1 to 5): (5 to 15): (0.1 to 0.5): (0.1 to 0.5): (0.5 to 5). The modified magnesite fireproof door core board of the invention has the characteristics of high bending strength, stable structure, fire resistance, fireproof performance and the like, is harmlessto human bodies and environment and the like, and is wide in application range. The preparation method effectively ensures the performance stability of the modified magnesite fireproof door core board and improves the fire resistance and fireproof performance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a modified magnesite fireproof door core board, a preparation method thereof and an application of the modified magnesite fireproof door core board. Background technique [0002] With the development of society, dense population, high-rise buildings, the fire prevention of building materials is related to the lives of many people, and the search for high-quality and low-cost fireproof and thermal insulation materials has always been a concern of the building materials industry. The fire door is one of the most important links in many fire prevention links, and the fire door core board is the key to the fire prevention of the fire door. [0003] At present, there are two main types of fire door core panels, one is organic insulation materials, such as XPS, PVC, PUR, PE, EPS, etc., due to the amount of smoke and smoke poison after burning, it may bring greater fire haz...
