B, glass thread stone, sepiolite, brucite and fast T are added in the synthesis reactor stirred 10～15 minutes again;
C, then successively lithium silicate, attapulgite, Magnesium Carbonate Light 41-45, titanium dioxide, carboxymethyl cellulose, magnesium oxide, ceramic fine bead and perlite are added synthesis reactor and stirred 35～75 minutes;
D, the slurry that reaction is finished are cooled to normal temperature, behind 2～4 hours natural froth breakings, namely make slurry finished product of the present invention.
In above-mentioned, meter is preferably by weight:
75.0 parts in 4.3 parts of attapulgites, 4.0 parts of perlites, 3.2 parts of ceramic fine beads, 2.5 parts in stone of glass thread, 2.7 parts of sepiolites, fast T0.75 part, 0.5 part of Magnesium Carbonate Light 41-45,2.5 parts of brucites, 0.5 part of aluminosilicate fiber cotton, 0.65 part of lithium silicate, 0.85 part in magnesium oxide, 0.18 part of titanium dioxide, 0.5 part of carboxymethyl cellulose and water.
In step b and step c, the rotating speed of stirring is 70～100 rev/mins.
Comprise that further the slurry that steps d is made puts into the die molding machine moulding, and put into baking room baking 18～26 hours, namely get solid finished product of the present invention.
Attapulgite, glass thread stone, sepiolite, brucite all contain fibrous Magnesium Silicate q-agent in above-mentioned prescription, one of characteristic is the moisture of adsorbable own wt 150%, stay the fiber that contains micropore behind the moisture drying, aluminosilicate fiber cotton also is fibrous, and this type of fibrous material has consisted of the skeleton structure of lagging material of the present invention.Perlite, ceramic fine bead are particle (band micropore) shapes in the prescription, be filled in the fiber reinforcement of material, titanium dioxide, magnesium oxide can reduce thermal-radiating, formation has fiber grain micropore composite structure under the glue of inorganic high-temperature agglomerant connects, so that lagging material of the present invention can effectively deaden thermal conduction, convection current and radiation.
The present invention has added the materials such as glass thread stone, uses suitable water temperature and time to soak sepiolite, attapulgite, glass thread stone in production technique, and stirs under the rotating speed of the best, and the product of producing is compared with composite aluminium-magnesium-silicate thermal insulating material and had the following advantages:
Shrinking percentage is little, and shrinking percentage of the present invention is 10～20%, and composite aluminium-magnesium-silicate is 25～35%;
Dry density is little, 180kg～220kg/m
3, composite aluminium-magnesium-silicate is 300kg～35kg/m
3
Intensity is high, does not need metal-ware during construction, and composite aluminium-magnesium-silicate is easily broken broken;
But the mould investment is saved in the demoulding behind the sizing material forming (fingerboard material), and composite aluminium-magnesium-silicate can not the demoulding;
Drying time is few, saves the energy, the oven dry in 18～22 hours of 3cm sheet material, and composite aluminium-magnesium-silicate needs oven dry in 24～28 hours;
Yield rate is high, and qualification rate is 98%, and the composite aluminium-magnesium-silicate yield rate is low, and qualification rate is about 50%, so cost is high.
Lagging material of the present invention can use in-40 ℃～800 ℃ scopes, and it is low to have a thermal conductivity, thermal conductivity 0.059W/mk in the time of 70 ℃, and particularly Thermal Conductivity at High Temperature is low, and 350 ℃ of thermal conductivity 0.085W/mk are better than other lagging material greatly.In the situation of equal heat insulation effect, lagging material of the present invention can reduce by 30～50% insulation thickness than other lagging material of market.Material non-toxic of the present invention, "dead" without burn into, uninflammability are A
1Level, safety performance is good; And the raw material of prescription can be recycled and can repeat processing, meets the requirement of recycling economy and environmental protection.Thermal insulation material of the present invention has a wide range of applications in industry, the adiabatic field of civilian insulation, and particularly current building thermal insulation material will reach under the mandatory requirement of A level (uninflammability), has especially unrivaled superiority.
