The preparation method of novel energy-saving inorganic thermal insulation plate
Technical field
The present invention relates to a kind of material of construction, specifically the heat insulation preparation method of a kind of novel energy-saving inorganic.
Background technology
Lagging material on construction market is various in style at present, and as hollow concrete block, interbedded water mud product, extruded sheet etc., hollow concrete block and interbedded water mud product are large because of its load-bearing, cause producing, taking time and effort when constructing, and effect of heat insulation is undesirable; And extruded sheet not only cost is too high, and due to the combustibility of extruded sheet, can discharge obnoxious flavour during burning, as CO, CO
2Deng.And when construction, require first levelling to lay, also to add iron wire or the reinforcing bar of diameter 4-8mm above extruded sheet, then spread the concrete mortar, re-lay the higher wear resistant products of steel brick or color density and beautify roofing, so both increased construction cost, also increased the load of buildings, and be difficult to apply.Therefore, develop a kind of good heat-insulation effect, cost is low, quality is light, the lagging material of easy for installation and energy-conserving and environment-protective, just becomes the objective of the struggle that the knowledgeable people seek assiduously.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of novel energy-saving inorganic thermal insulation plate by the novel energy-saving inorganic thermal insulation plate that the inventive method prepares, has good heat-insulation effect, cost is low, quality is light, the characteristics of easy for installation and energy-conserving and environment-protective.
Technical scheme of the present invention is such: the preparation method of novel energy-saving inorganic thermal insulation plate, realize as follows:
One, preparation slurry:
A, the magnesium chloride and the sal epsom that are 5-7: 0.75-1 with mass ratio are dissolved into the mixing solutions that concentration is the 24-26 degree Beaume;
B, the mixing solutions of getting 80-100 weight part steps A gained and the magnesium oxide of 100-120 weight part mix, and stir to obtain gelinite;
Add the environment-protection filling material of 20-95 weight part in C, the gelinite with step B gained, and stir;
D, add again the polyphenyl alkene foam of 5-15 weight part on the basis of step C, again stir;
E, add again the antioxidant SP of 0.2-1.0 weight part on the basis of step D, again stir, obtain required slurry;
Two, moulding: adopt known technique commonly used, will be pressed into blanket through slurry and the lining material one that step 1 prepares by the plate forming sheet-leveling machine;
Three, maintenance: above-mentioned blanket is delivered in curing room under normal temperature maintenance 12-24 hour;
Four, the demoulding: the demoulding by conventional methods obtains slab;
Five, secondary maintenance: the slab buttress that the above-mentioned demoulding is obtained piles up normal temperature laboratory and carried out the secondary maintenance 7-30 days, namely obtains novel energy-saving inorganic thermal insulation plate of the present invention.
In above-mentioned steps C, described environment-protection filling material comprises the stone flour of 20-80 weight part, and the wood saw end of 0-15 weight part or straw end.
In above-mentioned steps E, also add the silicon-dioxide of 0.1-0.5 weight part.
In above-mentioned steps E, also add the titanium dioxide of 0.1-0.5 weight part.
In above-mentioned steps two, lining material used is glass-fiber-fabric and non-woven fabrics, and slurry is tiled between glass-fiber-fabric and non-woven fabrics.
Above-mentioned glass-fiber-fabric is two layers to four layers that are stacked.
After adopting such scheme, in the inventive method, take magnesium oxide, magnesium chloride and environment-protection filling material as main raw material, and add polyphenyl alkene foam and antioxidant SP is made slurry.The environment-protection filling material can adopt wood saw end or straw, and the discarded stone flour of stone processing industry, adds stone flour and can reduce magnesian consumption, saves cost; Add wood saw end or straw and can strengthen toughness and the splitting resistance of goods, and be the waste recycling, economize on resources, reduce costs; Antioxidant SP have do not absorb heat, the characteristics such as resistance to oxidation; Polyphenyl alkene foam can reduce the density of goods, and can cut off the pore of goods, the favourable halogen that returns, the water-intake rate of minimizing goods.Therefore, by the prepared novel energy-saving inorganic thermal insulation plate of the inventive method, have good heat-insulation effect, cost is low, quality is light, the characteristics of easy for installation and energy-conserving and environment-protective; And there is no waste in production process, meet the production requirement of environment-friendly type.
In the inventive method, the silicon-dioxide that adds in slurry and titanium dioxide can increase wear resistance, acid resistance and the oil-proofness of goods.
In the inventive method, use glass-fiber-fabric as lining material in moulding, can strengthen the intensity of goods, and improve the heat-proof quality of goods.
Embodiment
The preparation method of novel energy-saving inorganic thermal insulation plate of the present invention, realize as follows:
One, preparation slurry:
A, the magnesium chloride and the sal epsom that are 5-7: 0.75-1 with mass ratio are dissolved into the mixing solutions that concentration is the 24-26 degree Beaume, best desirable 7: 1 of the mass ratio of magnesium chloride and sal epsom, desirable 25 degree Beaume of the optimum concn of this mixing solutions;
B, the mixing solutions of getting 80-100 gram steps A gained and the magnesium oxide of 100-120 gram mix, and stir and obtain gelinite, and the optimum amount of this mixing solutions can be 100 grams, and magnesian optimum amount can be 100 grams;
Add the environment-protection filling material of 20-95 weight part in C, the gelinite with step B gained, and stir, the environment-protection filling material here can use the stone flour of 20-80 gram, and the wood saw end of 0-15 gram or straw end; Stone flour, wood saw end or straw end are ground into 120-200 purpose fineness;
