Abstract

The invention belongs to the technical field of building materials, and in particular relates to a cement particle board and a preparation method thereof. The cement particle board is characterized by comprising the following components in parts by weight: 10-40 parts of wood shavings, 15-50 parts of high-calcium coal ash, 30-55 parts of sulfate aluminum cement, 2-5 parts of sodium silicate and 0.2-2.2 parts of calcium chloride. The cement particle board provided by the invention is light in weight, high in strength and low in manufacturing cost; as sulfate aluminum cement is adopted to replace ordinary Portland cement of the prior art, the cement particle board provided by the invention is short in production period, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a cement particle board and a preparation method thereof. Background technique [0002] Cement particleboard has been widely used abroad as interior and exterior wall panels, partition panels, floors, sound barrier materials on both sides of railways or roads, etc., and its domestic application is gradually expanding. This kind of board is generally made of cement, wood shavings, fly ash and various additives. The board has high strength, good fire and flame retardancy, and good water resistance and sound insulation performance. However, in order to ensure the physical and mechanical properties such as the strength of the cement particle board, it is usually required that the calcium content of the fly ash is low, and the calcium oxide content is generally lower than 8%. [0003] For example, Chinese patent CN200310106131.X discloses a wood-reinforced ceme...
