Abstract

The invention relates to a fire-proof board used for antique buildings, belongs to the field of refractory materials, and aims to solve the technical problems in the prior art that the noxious fumes are released when the fire-proof board is fired, the density is large, the production material of the fire-proof board has strong danger and the accident threat for safety in production exists and so on. The fire-proof board used for antique buildings contains the following components by weight part: 18-24 parts of calcined magnesium oxide, 7-15 part of industrial magnesium chloride, 3-6 parts of glass fibers, 35-60 parts of light-weight fillers, 1-2 parts of modifiers and 20-35 parts of water. The light-weight fillers are a mixture of any one, or two of expanded perlite and expanded vermiculite at any proportion. 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 ...
