Abstract
The invention provides a thermal insulation cement which comprises the following components in parts by mass: 60-70 parts of cement clinker, 15-20 parts of vermiculite powder, 12-16 parts of fluorogypsum, 3-5 parts of fly ash, 5-8 parts of gypsum, 3-5 parts of slag and 0.3-0.4 part of alum. The thermal insulation effect of the thermal insulation cement is 35% higher than that of Portland cement, and the thermal insulation cement has favorable thermal insulation effect.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of insulating cement.
Background technology
The heat-insulating and energy-saving of building construction is at present the most important thing in saving work.Current practice is to reach energy-conservation object at the additional one deck thermofin (layer of polystyrene foam or thermal insulating coating) of external wall.Wherein, though adopt the way of layer of polystyrene foam to have suitable effect of heat insulation, its construction is complicated, cost is high and also easy care not lastingly not.And although the way of thermal insulating coating construction is simple, cost is low, because of the too thin effect of heat insulation of its coating very poor.
In fact, the cement that buildings uses, itself is also a kind of thermally-insulated body, and just its effect of heat insulation is very poor, so change cement structures, improves a cement heat-proof quality shortcut beyond doubt.
Summary of the invention
The invention provides a kind of insulating cement.
The invention provides a kind of insulating cement, comprise each component of following mass fraction: cement clinker 60-70 part, vermiculite power 15-20 part, fluorgypsum 12-16 part, flyash 3-5 part, gypsum 5-8 part, slag 3-5 part, alum 0.3-0.4 part.
Preferably, comprise each component of following mass fraction: 65 parts of cement clinkers, 18 parts of vermiculite powers, 15 parts of fluorgypsums, 4 parts, flyash, 6 parts, gypsum, 4 parts, slag, 0.35 part, alum.
The present invention also provides the preparation method of above-mentioned insulating cement, is in 60-70 part cement clinker, to add vermiculite power 15-20 part fluorgypsum 12-16 part, flyash 3-5 part, gypsum 5-8 part, slag 3-5 part, alum 0.3-0.4 part, the common levigate cement products of making.
The effect of heat insulation of insulating cement of the present invention improves 35% compared with Portland cement, has good effect of heat insulation.
