Abstract
The invention discloses a cement foaming insulating plate with low heat conductive performance and a preparation method thereof. The plate consists of cement, coal ash, micro silicon powder, polyphenyl granules, hard calcium carbonate, polypropylene short fiber, molten ferric trichloride, dispersible emulsion powder, an organic silicon water repellent and hydrogen peroxide in percentage by weight. The preparation method comprises the following steps: uniformly mixing cement, coal ash, micro silicon powder, polyphenyl granules, hard calcium carbonate, polypropylene short fiber, molten ferric trichloride, and the organic silicon water repellent by proportion; adding into hot water at 45-55 DEG C; stirring for 5-10 minutes; adding dispersible emulsion powder and then stirring for 1-2 minutes; then, adding a foamer and then quickly stirring for 5-10 seconds; quickly injecting to a mould for foaming; demolding after molding; and cutting and packaging to obtain a product. The heat conductivity coefficient of the cement foaming insulating plate disclosed by the invention is remarkably reduced, so that the plate is suitable for areas with cold climate, and meets the existing energy-saving demand of the country.
Description
Technical field
The present invention relates to a kind of fireproof heated board, especially a kind of low heat conductivity can cement foamed warming plate, also relate to the preparation method of this cement foamed warming plate.
Background technology
Cement foamed warming plate, the warming plate that refers to use the foam cement technology to make claims foamed concrete warming plate, inorganic fire warming plate again.Be to be material with ordinary Portland cement, flyash, whipping agent, additive etc., the lightweight air bubble-shaped fire-proof heat-insulating material of making through technologies such as mixing, stirring, injection molding, foaming, moulding, cutting, maintenances.
The foaming cement thermal insulation plate belongs to non-fire material, nontoxic, environmental protection, low-carbon (LC), and its fire resistance reaches the A1 level.This product ultimate compression strength height (with polyphenyl foam than), thermal conductivity is lower, firm with concrete bonding, coefficient of expansion unanimity, working life and buildings basically identical are applied to the fireproof heat insulating engineering of skin in recent years gradually.Though comparing than other inorganic building materials, the foaming cement thermal insulation plate has good relatively heat-insulating property, but the cement foamed warming plate of producing according at present used raw material and preparation method, its density is 220-240kg/m3, thermal conductivity is 0.07 W/(m.k) about, the styrofoam of using in the building exterior wall heat preserving system construction at present (EPS), extruded sheet (XPS), phenolic foam board, rock cotton board thermal conductivity 0.03-0.04 W/(m.k) compares about, its heat-insulating property still is relatively poor, be not suitable for the zone in cold climate area, do not reach the present energy-conservation requirement of country basically.
Summary of the invention
Task of the present invention provides a kind of cement foamed warming plate of low heat conductivity energy, and the preparation method of this cement foamed warming plate also is provided.
For realizing above-mentioned task, technical solution of the present invention is, a kind of low heat conductivity can cement foamed warming plate, it is made up of the component of following weight degree,
Cement 60%-70%
Flyash 10%-20%
SILICA FUME 3%-8%
Granular polystyrene 1%-3%
Hard calcium carbonate 1%-2%
Polypropene staple 0.5%-1%
Tri-chlorination molten iron 1%-2%
Polymer dispersion powder 1%-2%
Organosilicon moisture repellent 0.5%-1%
Hydrogen peroxide 4%-8%
The preparation method of the cement foamed warming plate of described low heat conductivity energy, cement, flyash, SILICA FUME, granular polystyrene, hard calcium carbonate, polypropene staple, tri-chlorination molten iron, organosilicon moisture repellent are mixed in proportion, join in 45 ℃-55 ℃ the hot water, stirred 5-10 minute, added the polymer dispersion powder restir 1-2 minutes, and added whipping agent then and stirred fast for 5-10 seconds again, inject mould rapidly and foam, the demoulding after the moulding, the cutting packing is finished product.
The density of the cement foamed warming plate of low heat conductivity energy of the present invention is 180-200kg/m3, and thermal conductivity is 0.050-0.054 W/(m.k), thermal conductivity obviously reduces, and is suitable for the zone in cold climate area, reaches the present energy-conservation requirement of country.
