Abstract

The invention relates to a dynamic hot water reaction hard microporous fiber calcium silicate board which is characterized in that a board body is obtained through a reaction of ingredients and water in the weight ratio of 1:4. The ingredients comprise the following components in proportion (molar ratio): 45-47 percent of siliceous material, 40-42 percent of calcareous material, 7 percent of fiber and 6-7 percent of reaction promoter, wherein the siliceous material is one or a mixture of diatomaceous earth, quartz powder, glass dust, opoka and river sand powder; the calcareous material is lime and / or cement; the fiber is one or a mixture of mineral fiber, vegetable fiber and polymer fiber; and the reaction promoter is water glass and / or bentonite. The ingredients which do not contain toluene, formaldehyde or radioactive substances are adopted to react with water in the invention, so that no harmful gas is produced. The finished product has fire prevention, moisture prevention, mold prevention, high tensile strength, high flexural strength and good temperature resistance, and is a multipurpose product suitable for internal walls, external walls and ground surfaces.
