A preferred embodiment, the compound external-wall heat-insulation material of this diatomite is comprised of following compositions in weight percentage: modification infusorial earth 38%, fine perlite 41%, calcium hydroxide 15%, xylon 2%, rubber powder 2%, hydrophobic type binding agent 2%.
Another kind of preferred embodiment, the compound external-wall heat-insulation material of this diatomite is comprised of following compositions in weight percentage: modification infusorial earth 36%, fine perlite 42%, calcium hydroxide 14%, xylon 3%, rubber powder 3%, hydrophobic type binding agent 2%.
Above-mentioned modification infusorial earth by diatomite original ore, be dried, repeatedly pulverize and sorting after carry out again modification gained, above-mentioned hydrophobic type binding agent is edible seaweed powder.
The production technique of the compound external-wall heat-insulation material of this diatomite, comprises the following steps:
One, by diatomite original ore seasoning, weathering, sun-dried mud brick grouping system grade;
Two, being transported to job shop pulverizes and selection by winnowing repeatedly;
Three, at 200-300 ℃, carry out modification and obtain modification infusorial earth;
Four, the hundreds of proportions by subtraction of parts by weights are got modification infusorial earth 35～38%, add fine perlite 40～42%, calcium hydroxide 12～15%, xylon 2～4%, rubber powder 2～3%, hydrophobic type binding agent 1～2% to mix and get final product to obtain the compound external-wall heat-insulation material of diatomite.
From the above-mentioned description to structure of the present invention, compared to the prior art, tool of the present invention has the following advantages:
1, the compound external-wall heat-insulation material of diatomite of the present invention is two component external-wall heat-insulation materials, take fine perlite as base-material, modification infusorial earth be main additive, add again with some auxiliary materials, diatomite main component is amorphous silicon di-oxide, surface arrangement is nanometer level microporous in a large number, therefore thermal and insulating performance is good and be non-fire material, and its use temperature is between-50 ℃-50 ℃.
2, this lagging material can directly be put on skin in use as mortar, reach and be not only incubated but also can fp effect, and in construction, be the form appearance with mortar, the problems such as thereby the gap of having avoided sheet material construction is difficult and cohere, and intensity is large, good integrity, low-temperature construction performance is good, cost performance is high, it is the green lagging material that a kind of novel energy-saving environment-friendly does not fire again, its technical indicator reaches or completely higher than the technical indicator of GB/T20473-2006 < < building heat-insulating mortar > > standard.
3, the compound external-wall heat-insulation material of diatomite of the present invention adds hydrophobic type binding agent, make this lagging material be put on external wall after slowly seasoning, cohesiveness is good, and waters without artificial not timing External Wall, does not occur the phenomenons such as crack after dry.
4, lagging material of the present invention is the particulate state that evenly nothing is lumpd, and it is very convenient to transport and deposit, and can long storage time never degenerate, and only needs it to mix with water in right amount during construction, and in addition, this lagging material production technique is simple.
