Special insulating cement

Abstract

Insulating cement is made from the following components by weight percent: 35-73% of a cement clinker, 5-10% of vermiculite powder, 1-8% of titanate, 20-45% of fluorgypsum and 0.05-2% of a cement hardener. The special insulating cement has the advantages that: cement technology is combined with chemical technology, the cement has simple production process, improved heat insulating performance more than double of heat insulating performance of common cement, obvious insulating effect with a temperature difference of 6-10 DEG C and requires the same method for use as the common cement, keeps all performances of the common cement, has permanent weathering resistance and water resistance, and is suitable for use under any condition with variable temperature; the cement is disposable without needing maintenance; and moreover, the insulating cement is also capable of closely binding with a steel plate and can be used for rust prevention of the steel plate, thus being taken as an rust-preventing insulating layer of a large oil tank.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to 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 layer (polystyrene foam layer or heat insulation coating) to the building exterior wall to achieve the purpose of energy saving. 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. [0003] In fact, the cement used in buildings is itself a kind of heat insulator, but its heat insulation effect is very poor, so changing the cement structure and improv...

AI Technical Summary

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.

[0003] In fact, the cement used in buildings is itself a kind of heat insulator, but its heat insulation effect is very poor, so changing the cement structure and improving the heat insulation performance of cement is undoubtedly a shortcut. reports on this
