Abstract

The invention relates to a fire-proof board used for antique buildings and a production method thereof, belongs to the field of refractory materials, and aims to solve the technical problems of the prior art, such as large density, poor fire resistance, low strength and release of noxious fumes during fire. The fire-proof board used for antique buildings contains the following components in weight part: calcined magnesium oxide 18-24, industrial magnesium chloride 7-15, glass fibers 3-6, light-weight fillers 35-60, modifiers 1-2 and water 20-35. The production method of the fire-proof board comprises the following steps: (1) mixing calcined magnesium oxide, light-weight fillers and glass fibers at the give ratio to obtain a mixture; (2) mixing industrial magnesium chloride with water to form solution, adding the solution into the mixture under stirring; 3 adding the modifiers during the stirring procedure; 4 stirring for 1-5 min and discharging; and 5 molding to obtain boards, drying and curing. The fire-proof board is suitable for fire protection of antique buildings.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a fireproof board used in ancient buildings and a preparation method thereof. Background technique [0002] The 5,000-year history and civilization of the Chinese nation has bred a splendid Chinese culture, and a large number of ancient buildings have been left over from various dynasties in history. These ancient buildings have high spiritual value, cultural value and practical value. Therefore, it is of great significance to strengthen the protection of ancient buildings and ensure the safety of ancient buildings. [0003] Many ancient buildings in our country are mostly made of wood and wood structures, the fire load density is high, and flashover is prone to occur. In addition, in ancient buildings, there are many fire factors, difficult to extinguish and rescue, and most of them do not have fire protection division. Therefore, once a fire occurs in ancient buildings, it ...
