Problems solved by technology

Among them, although the method of using polystyrene foam layer has a considerable heat insulation effect, its construction is complicated, the cost is high, and it is not durable and difficult to maintain.
Although the method of thermal insulation coating is simple in construction and low in cost, its thermal insulation effect is poor because the coating is too thin.

Embodiment Construction

[0006] The technical solution of the present invention is a kind of heat-insulating cement, whose components by weight percentage are: 8 parts of vermiculite powder, 66 parts of cement clinker, 4 parts of gypsum, 5 parts of slag, 6 parts of titanate, 27 parts of fluorogypsum, 4 parts of cement accelerator, 8 parts of thermal insulation filler, 5 parts of thickener, and 7 parts of bentonite.

[0007] Further, described bentonite can also adopt diatomite, particle diameter is at 120-200um.

[0008] The invention combines the cement technology with the chemical technology, the production process is simple, the heat insulation performance is improved by more than 30% compared with the ordinary cement, the temperature difference of the heat insulation effect is 6-10°C, the use method is the same as the ordinary cement, and it retains the ordinary cement It has all the properties of permanent weather resistance and water resistance, and is suitable for use under any temperature chan...

Abstract

The invention discloses thermal-insulating cement. The thermal-insulating cement comprises the following components by weight percentage: 5-10 parts of vermiculite power, 35-73 parts of cement clinker, 3-5 parts of gypsum, 3-5 parts of slag, 1-8 parts of titanate, 20-45 parts of fluorgypsum, 2-6 parts of a cement accelerator, 6-9 parts of a heat-insulation filling material, 3-6 parts of a thickening agent, and 5-10 parts of bentonite. Compared with common cement, the heat-insulation effect of the thermal-insulating cement is increased by 30%, and the thermal-insulating cement has good heat-insulation effect.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to a special heat-insulating cement. Background technique [0002] At present, the heat insulation and energy saving of housing construction is the top priority in saving work. The current method is to add a layer of heat insulation (polystyrene foam layer or heat insulation paint) to the building's exterior wall to achieve energy saving purposes. Wherein, although the method of adopting the polystyrene foam layer has considerable heat insulation effect, its construction is complicated, the cost is high, and it is neither durable nor easy to maintain. Although the method of heat-insulating coating is simple in construction and low in cost, its heat-insulating effect is very poor because the coating is too thin. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a hea...
