Background technology
Inorganic heat insulation material has characteristics such as intensity height, the fire protection flame retarding security is good, thermal property is good, construction is convenient, stability is high, environmental protection is nuisanceless, is subjected to numerous clients' favor day by day.Because common magnesium cement material has intensity height, performance such as fire-resistant, anticorrosion, but other lagging material of the volume to weight ratio of common magnesium cement is big, this point has restricted the development of common magnesium cement as lagging material, therefore utilize it to add whipping agent and produce the magnesium cement foam material, reduce its unit weight and become a kind of trend, but existing foaming technique expansion rate is slow, foaming is inhomogeneous, is not suitable for large-scale industrial production, has also influenced the heat-insulating property of product simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of lightweight, has the magnesium cement foam material of good thermal insulation property.
For addressing the above problem, a kind of magnesium cement foam material of the present invention, it is characterized in that: after this material is mixed by 10～90%, 5～89%, 0.8～10% weight percent by light-magnesite powder, filler and compound foaming agent, with 100～150% mix magnesium chloride solutions of mixture total weight amount; Through stir, casting promptly.
Described light-magnesite powder is meant magnesite at 600 ℃～900 ℃ light calcined magnesias that temperature lower calcination forms; Or the magnesia powder that Bischofite in Salt lake is obtained through pyrolysis; Or the magnesia powder that rhombspar is obtained through half-baked; Wherein the content of magnesia in the light-magnesite powder is 75%～85%.
The mass concentration of described magnesium chloride solution is 20～26%.
Described filler is a kind of in mineral filler or the organic filler.
Described mineral filler is meant flyash, ground dolomite, Paris white, terra alba or perlite.
Described organic filler is meant sawdust, rice husk, stalk, marine alga.
Described compound foaming agent is mixed by 90～95%, 1～6%, 1～5% mass percent by superoxide, treating compound, suds-stabilizing agent; Described superoxide is meant sodium peroxide, Potassium peroxide or hydrogen peroxide; Described treating compound is meant alkyl sulfonates or alkyl benzene sulfonate; Described suds-stabilizing agent is meant lauryl alcohol.
The present invention compared with prior art has the following advantages:
1, because the present invention is added with compound foaming agent, this compound foaming agent has that expansion rate is fast, uniform in foaming, be easy to the characteristics that realize that large-scale industrialization is produced, therefore, make the present invention not only have the performance of common magnesium cement, and improved heat-insulating property.
2,, therefore, have light weight, characteristics that toughness is strong because the present invention is added with inorganic or organic filler.
3, the present invention after tested unit weight be 400kg/m 3～900kg/m 3Thermal conductivity is 0.06～0.25W/ (M.K), thermal resistance is about 10～20 times of normal concrete, not only can effectively reduce the carrying of buildings, and heat-insulating property is good, simultaneously because the fire resistance of magnesium cement is far superior to the organic insulation material of present widespread use, therefore, the present invention can be widely used in building block in industry, the covil construction and Thermal Equipment and various ventilator trunk, industrial pipeline.
