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
The present invention relates to a kind of light wall board for partition of buildings and preparation method thereof.
Background technology
Concrete light wall panel is as a kind of novel wall material, and have light weight light weight, intensity height, fast, energy-conserving and environment-protective are installed, characteristics such as fire prevention, protection against the tide and civilized construction, current being widely used in the buildings, development prospect is wide.At present, the composition of producing Light trabs mainly comprises cement, flyash, polyvinyl alcohol, magnesium chloride, six pieces of sodium phosphates, magnesium oxide etc., also interpolation such as sawdust or the vegetable fibre etc. that have.Above-mentioned Light trabs since raw material select for use with proportioning on difference, so have the moisture absorption, anti-halogen, yielding, produce check surface, intensity reduction etc. thus, use until influence is normal.
Summary of the invention
The purpose of this invention is to provide a kind of light wall board for partition of buildings and preparation method thereof, by a large amount of tests, employing is the new prescription of raw material with silicate cement, flyash, slag, swelling agent, leca, river sand etc., also fully use production line tankage, waste and old work in-process and waste and old finished product, thereby overcome the defective that exists in the currently available products preferably.
The component and the proportioning that realize Light trabs of the present invention are:
