3, the effect that mainly play weight reduction, sound-insulating and heat-insulating insulation, fireproof, reduces cost.
Described magnesian content 〉=85%, its active oxidation Mg content 〉=65%, have not been cooked or heated long enough burn till part≤2%, overdo burn till part≤3%, free calcium oxide content≤2%, ferric oxide≤1.5%, loss on ignition≤15% mainly plays gelling, the effect of gaining in strength.
Described sal epsom mainly plays solidification, the hole that reduces the goods hardenite is arranged, to returning halogen and returning the modifying function of frost, increases waterproof and water resistance, avoids the corrosion of iron sheet, plays the rust protection effect.
Described water soluble adhesive is a butadiene-styrene latex, and the solids content of its aqueous solution is 45~52%, mainly plays bonding effect.
Described water-resisting agent is a waterproofing agent of organosilicon, mainly has been gap and transparent performance that pore is stopped up in sealing, improves structure, improves water resisting property, reduces water-intake rate.
The preparation method of described lightweight fireproof filling material, it comprises the steps:
(1), will mix in pearlstone, magnesium oxide, sal epsom, white lime, the water-resisting agent adding stirrer with order by weight proportion;
(2), simultaneously be emulsion with the water soluble adhesive thin up, and add in proportion in the stirrer that it is even to carry out secondary stirring again, water content requires material to be pinched with hand agglomerating, loses the degree that can scatter again on the ground and is advisable;
(3), compound is added use press compression moulding in the mould;
(4), after the demoulding, one week of natural curing become finished product in summer under the normal temperature and pressure, the maintenance of need heating winter.
After adopting above-mentioned technical scheme, the present invention has following advantage:
1, the present invention's mechanical-physical drawing method, in pearlstone, add thick shape gelling slip, in mixing the process that stirs, the pearlstone surface is formed one deck waterproofing membrane seals pore, both pearlstone was played the waterproof resistance effect, bonding effect is arranged again, make expanded perlite granule mutually bonding and form a monoblock through compacting, thereby make lightweight fireproof filling material of the present invention have the performance of adiabatic heat-insulation, sound absorption sound insulation, obvious energy conservation, it is easy and simple to handle, less investment, cost are low;
2, the present invention can prevent damp suction surface halide accumulation, craze and transfiguration;
3, the structure that bonded together by expanded perlite granule of goods of the present invention changes the size of unit weight and intensity by the consumption of adjusting particle diameter size and gelating material, and setting range is big, and unit weight can be at 200~300kg/m
3Between select for use arbitrarily according to purposes so that satisfy the requirement of different functions of use;
4, the present invention uses butadiene-styrene latex as water soluble adhesive, thereby water-absorbent, cost value of having improved the perlite surface etc. all are better than existing other caking agent, its major cause is that it is a water soluble adhesive, to producing low-density goods beyond thought adhesive effect is arranged, it is big that power is stained with on the surface, bonding stability is strong, helps controlling stopping composition unit weight size, thereby can make goods unit weight at 200~300kg/m
3Between adjust arbitrarily, can widen Application Areas of the present invention greatly like this; Also improve freeze thawing intensity simultaneously, done wet tenacity, softening intensity and corrosion resistant ability, waterproof water resistance and energy-saving effect.
5, goods of the present invention can be used as metal anti-theft safety door, metal entering house door, fire metal door inner filling material, it is the substitute that replaces honeycomb paper, calcium silicate board and aluminium silicate wool, its cost is than calcium silicate board and aluminium silicate wool low about 60%, reduce the usage quantity of honeycomb paper, very big potentiality are also arranged saving forest resourceies; Can change traditional stopping composition honeycomb paper, calcium silicate board and aluminium silicate wool and fill that difficulty is big, the backwardness of complex manufacturing, raise labour productivity, shorten the production cycle, be once great technological change to the production of metal door; The present invention is used for building material industry, and consumption is very huge.
