Description
technical field
The present invention relates to a kind of preparation method of desulfurated plaster foaming cement thermal insulation plate, belong to technical field of inorganic chemical industry.
background technology
Why huge China's architectural energy consumption is, and its main contributor is that the heat transfer coefficient of building maintenance structure is excessive, and heat retaining property is poor, and development of new wall heat insulation material is imperative.The lagging material that the traditional wall thermal insulating system of China adopts is generally the organic materialss such as polystyrene foamed (EPS) or extruded polystyrene (XPS), but these materials have exposed increasing problem in long-term use procedure, as inflammable, easily aging, come off, maintain and replace complexity etc., especially in recent years by several fire disaster accidents of initiation, cause a large amount of loss of life and personal injury and property damage to country and society, suffer extensive query.Foaming cement thermal insulation plate, because it has the plurality of advantages such as lightweight, insulation, heat insulation, sound insulation, anti-seismic performance be good, occupies critical role in Development of Novel energy-saving wall and roof heat insulation, heat-insulating technique and material.
The early strength of foaming cement thermal insulation plate is low, and conventionally improving foaming cement thermal insulation plate early strength quick-drying hardening accelerator used or accelerating chemicals is aluminosulfate cement or ferro-aluminate cement; But aluminosulfate cement or ferro-aluminate cement price are high, resource scarcity, and there is to impact in the foaming cement thermal insulation plate later stage.
summary of the invention
The object of the invention is, the problem existing for traditional wall heat insulation material, the present invention discloses a kind of preparation method of desulfurated plaster foaming cement thermal insulation plate.
Realizing technical scheme of the present invention is, the preparation method of desulfurated plaster foaming cement thermal insulation plate of the present invention, to take ordinary Portland cement, flyash, desulfurated plaster as main gelling material, the foaming cement thermal insulation plate prepared by additional water reducer, polypropylene fibre, whipping agent, compound suds-stabilizing agent, for improving the early strength of foaming cement thermal insulation plate, it is desulfurated plaster that the present invention adopts hardening accelerator to foaming cement thermal insulation plate; Suds-stabilizing agent is the key that can foaming cement thermal insulation plate be made, and suds-stabilizing agent of the present invention is to form by Multicomponent is composite.
A kind of desulfurated plaster foaming cement thermal insulation of the present invention plate is comprised of the raw material of lower number of columns: ordinary Portland cement 150～180kg, flyash 50～80kg, desulfurated plaster 5～10kg, water reducer 0.4～0.8kg, polypropylene fibre 0.5～1.0kg, whipping agent 13.0～18.0kg, compound suds-stabilizing agent 0.75～1.0kg.
The preparation method of a kind of desulfurated plaster foaming cement thermal insulation of the present invention plate is: by formula, the powder weighing up is mixed: after starting stirrer, ordinary Portland cement, flyash, desulfurated plaster, water reducer, polypropylene fibre, suds-stabilizing agent are added, stir; Add again water and stir 2～3 minutes, add whipping agent rapid stirring 5～10 seconds; Foaming in injection molding immediately, maintenance, the demoulding, cutting, finished product maintenance.
Described flyash is second class powered coal ash; Described water reducer is poly carboxylic acid powder.
Described desulfurated plaster be power plant's water ratio 10% with interior desulfurated plaster through 160～180 ℃ of temperature calcine, the levigate desulfurated plaster that completes is to the conversion of semi-hydrated gypsum, its fineness is 160～200 orders.
Described whipping agent is content 27.3%H
2o
2liquid.
Described compound suds-stabilizing agent mixes Powdered by calcium stearate 2.0～3.0 kg, Magnesium Stearate 0.8～1.0 kg, light calcium carbonate 6.0～8.0 kg, trolamine 0.6～1.0 kg, polyacrylamide 0.6～1.0 kg, alkoxyl alcohol acid amides 0.4～0.8 kg, carboxymethyl cellulose sodium 0.6～1.2 kg, sesbania gum powder 0.8～1.6 kg component.
The invention has the beneficial effects as follows, its ultimate compression strength of desulfurated plaster foaming cement thermal insulation plate prepared by the present invention is good, and thermal conductivity is low, as wall thermal insulating product, not only improved the intensity of foaming cement thermal insulation plate and heat-insulating property, fire savety is good, and makes full use of the solid waste thing of power plant; Desulfurated plaster foaming cement thermal insulation plate technique prepared by the present invention is simple, cost of investment is low, environmental protection, economy.
