Method for producing preblended light aggregate concrete heat-preservation material

Abstract

The invention discloses a method for producing a preblended light aggregate concrete heat-preservation material. The heat-preservation material is prepared by uniformly mixing and blending spherical light aggregate, fine aggregate, cement, admixture and additives, wherein the fine aggregate is one or more of sand, pottery sand, tailing sand, steel slag and water-quenched slag; the admixture is coal ash and / or mineral powder; the additives comprise a water reducing agent and a water retaining agent; the production raw materials of the spherical light aggregate comprise sludge and mud; the production process comprises steps of blending, pelleting, screening, drying, combusting to puff, cooling in air and cooling naturally. The raw materials used in the heat-preservation material produced by using the method disclosed by the invention are all anti-combustion materials, so that a heat-preservation structure manufactured by using the heat-preservation material is good in fireproof function; as the spherical light aggregate is of a porous structure, good heat preservation and sound insulation effects are achieved. When being applied to heat-preservation construction of roofs or building surfaces, the heat-preservation material is only provided with a proper amount of water, is uniformly mixed and blended, and is subsequently paved on the ground or the roof, and then an integrated heat-preservation structure is formed after the heat-preservation material is cured. The strength of the heat-preservation structure is greatly improved, and the heat-preservation construction is also convenient.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials for buildings, in particular to a production method of ready-mixed light aggregate concrete thermal insulation materials. Background technique [0002] At present, the insulation material commonly used in the construction industry is insulation board. The insulation board is made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers. It is made by heating and mixing while injecting catalyst, and then extrusion molding. rigid foam board. The usual way to use insulation boards for ground or roof insulation is to splice and lay insulation boards on the ground or roof one by one, and then pour cement. After the cement solidifies, stick the insulation boards together to form an insulation structure. Using thermal insulation boards as thermal insulation structures can achieve thermal insulation, moisture resistance and certain sound insulation eff...

AI Technical Summary

Problems solved by technology

Using thermal insulation boards as thermal insulation structures can achieve thermal insulation, moisture resistance and a certain sound insulation effect, but due to the limitation of thermal insulation board materials, the thermal insulation structure does not have fire protection function, low strength, and construction is time-consuming and laborious
