Fireproof material for protective building material and preparation method thereof

Abstract

The invention provides a fireproof material for a protective building material and a preparation method thereof, the fireproof material for the protective building material comprises the following rawmaterials by weight: 15-60 parts of magnesium chloride, 12-55 parts of magnesium oxide, 10-30 parts of triethylene tetramine, 7-12 parts of ethylenediamine, 10-30 parts of aluminum hydroxide, 10-30 parts of resin, 15-55 parts of expandable graphite, 8-12 parts of hydrotalcite and 20-33 parts of a flame retardant; wherein the flame retardant is prepared from ammonium phosphate, pecan shells and borax in a volume ratio of (0.1-0.3): (1-5): (1.2-3); all the raw materials are mutually combined to synergistically exert the flame retardant property, and the optimal flame retardant effect can be achieved by adjusting the rate, the temperature and the time under specific process parameters.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fireproof material for protective building materials and a preparation method thereof. Background technique [0002] In recent years, the casualties and property losses caused by building fires have increased significantly, which has aroused the attention of all walks of life to thermal insulation and fire prevention. With the continuous development of my country's economic construction, buildings are developing towards large-scale, three-dimensional floors, and special structures. The performance index, technical content and product quality requirements of fireproof materials are higher. However, in order to improve the physical properties, the current fireproof building materials add more materials such as heat preservation and bending resistance. Not only the fireproof effect is poor, but once a fire occurs, the These additives continuously produce molten droplets, which pose...

[0002] In recent years, the casualties and property losses caused by building fires have increased significantly, which has aroused the attention of all walks of life to thermal insulation and fire prevention. With the continuous development of my country's economic construction, buildings are developing towards large-scale, three-dimensional floors, and special structures. The performance index, technical content and product quality requirements of fireproof materials are higher. In order to improve the physical properties, the current fireproof building materials add more materials such as heat preservation and bending resistance. Not only the fireproof effect is poor, but once a fire occurs, the These additives continuously produce molten droplets, which pose a serious threat to people's property and life safety.
