Light wall board for partition of buildings and method for preparing same

Abstract

The invention provides a construction partition used light wallboard and a preparation method thereof. The light wallboard comprises Portland cement, pulverized fuel ash, furnace slag, an expansion agent, clay porcelain granule, fluvial sand, expanded perlite, comprehensive materials including leftovers from production line, waste and old half-finished products, raw materials obtained by pulverizing and screening the waste and old half-finished products. The process method comprises the steps of adding more than 8 percent of the expansion agent to light concrete mixture; helically extruding and molding the mixture after automatic batch weighing, beating and mixing; the mixture is piled up and cured, and inspected before the product is delivered. The light wallboard is characterized in that by adding the expansion agent to the admixture, expansion energy is introduced; the chemical shrinkage of lightweight aggregate concrete is compensated through the expansion in volume, thus eliminating the shrinkage cracks of the wallboard; the compactness of lightweight aggregate concrete is improved; the impermeability is improved; the production process is simple and operated easily at low cost.

Description

technical field [0001] The invention relates to a lightweight wallboard for building partition walls and a preparation method thereof. Background technique [0002] As a new type of wall material, concrete lightweight wallboard has the characteristics of light weight, high strength, fast installation, energy saving and environmental protection, fire prevention, moisture resistance and civilized construction. It has been widely used in buildings and has broad development prospects. . At present, the ingredients for the production of lightweight wallboards mainly include cement, fly ash, polyvinyl alcohol, magnesium chloride, sodium hexaphosphate, magnesium oxide, etc., and some also add sawdust or plant fibers. Due to the differences in raw material selection and proportioning, the above-mentioned lightweight wallboards have moisture absorption, anti-halogenation, and easy deformation, resulting in surface cracks and reduced strength, until they affect normal use.
