Heat-insulation cement

Abstract

The invention discloses heat-insulation cement. The heat-insulation cement is prepared from the following raw materials in parts by weight: 20 to 50 parts of portland cement, 10 to 20 parts of limestone, 10 to 20 parts of clay, 5 to 10 parts of fly ash dreg, 5 to 10 parts of slag, 8 to 12 parts of bentonite, 1 to 5 parts of polyvinyl resin, 1 to 5 parts of manganese dioxide, 2 to 6 parts of hollowmicrospheres, 0.5 to 3 parts of sodium dodecylbenzene sulfonate and 90 to 130 parts of water. According to the heat-insulation cement provided by the invention, the portland cement, the limestone, the clay, the fly ash dreg, the slag, the bentonite, the polyvinyl resin, manganese dioxide, the hollow microspheres and sodium dodecylbenzene sulfonate are used as the raw materials, the ratio is reasonable and all components have the mutual effect and mutual influences; the prepared cement has good heat-insulation performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a 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. Contents of the invention [0003] In view of this, the object of the present invention is to provide a thermal insulation cement which has good thermal in...
