Inorganic heat preserving and heat insulation material mainly has: gypsum insulation plate, cement board etc..The cost of material is low for this type of, fire-retardant, ageing-resistant performance
Good but often unit weight relatively big, the overall weight of building can be increased and be unfavorable for high-rise use and material shortage toughness.
Magnesia oxychloride cement is a kind of morning being prepared from by light calcined magnesia and solidification blender magnesium chloride, water mix according to a certain percentage
Strong fast strong-willed hydraulic cement.The magnesia oxychloride cement concrete formed with a certain amount of sandstone, has lot of advantages, as hard in condensed
Change is fast, gelling is strong, high-strength, do not burn, maintenance is easy.With magnesium chloride as blender, give its good low-temperature resistance performance.
Magnesia oxychloride cement can reduce goods unit weight further for foam concrete.Can be used for ornament materials, fire-proof board etc., but chlorine oxygen magnesium
The general halogen of the easy moisture absorption of cement, buckling deformation etc., it is restricted in the application of exterior-wall heat insulation etc..
Existing magnesia oxychloride cement foam concrete stresses when producing to improve this feature of magnesium oxychloride cement product resistance to water, and have ignored
The feature of its light weight, goods unit weight is higher, and insulation, acoustically effective are poor, and production cost is high.So chlorine oxygen magnesium can not be promoted
The actual application of cement foam concrete.
[summary of the invention]
It is an object of the invention to overcome above-mentioned deficiency, it is provided that the preparation side of a kind of magnesia oxychloride cement foam concrete wall insulation material
Method, can be widely applied to wall thermal insulating, ground insulating, wall body decoration etc..

Step 3, is configured to the phosphate solution that mass concentration is 84～86% by water resistant additive,；
Step 4, is that 1 part of magnesium oxide mixes with filler and fiber by mass fraction, obtains magnesia oxychloride cement slurry, wherein, filler
Volume be oxidation magnesium amount 3%～4%, fibers content is the 0.6%～0.8% of magnesium oxide consumption；
Step 5, adds phosphate solution in salt with water reducer, stirs, by dried EPS granule and quality be
The foaming agent of magnesium chloride 12% adds, and is stirring evenly and then adding in magnesia oxychloride cement slurry, obtains mixture A；
Step 6, injects mould by mixture A, stands and makes it condense hardening；
Step 7, rear form removal of having hardened, at surface-coated methane-siliconic acid sodium solution, after natural curing, i.e. make magnesia oxychloride cement bubble
Foam concrete wall heat insulation material.
In described step 3, water resistant additive is phosphoric acid or phosphatic one.
In described step 4, magnesium oxide uses any one in light-magnesite powder, caustic dolomite powder.
If magnesium oxide derives from light-magnesite powder, wherein content of magnesia is 80～90%, and activity is 55～65%；If causticity
Dolomite dust, wherein content of magnesia is 20～30%, and activity is 14～15.5%.
In described step 4, filler includes at least one in industrial residue flyash, silicon ash, slag, desulfurated plaster.
In described step 4, fiber is polypropylene fibre.
In described step 4, in magnesia oxychloride cement slurry, the mass ratio of magnesium oxide and salt is 1:(0.5～1).
In described step 5, water reducer uses liquid poly carboxylic acid series water reducer, and its water-reducing rate is > 10%, volume is magnesium oxide quality
1～2%.
In described step 5, foaming agent uses hydrogen peroxide, and content 30%, its volume is the 12%～15% of magnesium oxide.
In described step 5, the volume of dried EPS is the 1%～3% of magnesium oxide.
Compared with prior art, the magnesia oxychloride cement foam concrete wall insulation material fast solidifying prepared by the present invention, with
Foam stabilizer need not be combined during foaming agent foam or retarder uses, mix EPS granule, increase goods inner air vent quantity, make to send out
Steep and in hgher efficiency reduce extrudate density simultaneously so that it is light weight insulation；Due in magnesia oxychloride cement mixed with fiber, improve system
Product surface strength, bending strength and the shear strength along plane, it is to avoid magnesium oxychloride cement product deforms, greatly because of pressurized etc.
Facilitate greatly stacking and the transport of magnesium oxychloride cement product, while keeping strength of wall body, can effectively alleviate again the load of building,
Make it use at high level to be possibly realized；Outer layer coating sodium methyl silicate waterproofing agent, improves article water resistance and fire protecting performance, we
