Heat insulation cement and preparation method thereof

Abstract

The invention discloses heat insulation cement. The heat insulation cement comprises the following raw materials in parts by weight: 113-115 parts of limestone, 3-5 parts of gypsum powder, 3-5 parts of dolomite, 12-14 parts of clay, 9-11 parts of river sand, 1-3 parts of apophyllite, 1-3 parts of stilbite, 6-8 parts of fly ash, 2-4 parts of rhodonite, 7-13 parts of siderite stone, 5-6 parts of slag, 10-13 parts of calcium carbonate, 8-10 parts of starch, 2-5 parts of asbestos wool and 2-5 parts of methylcellulose. By adding the combination of apophyllite, stilbite and rhodonite, the microstructure of the traditional cement is changed, and a second phase with excellent heat insulation performance is formed; the structural strength of the cement after hardening is improved by dispersion strengthening; in addition, the heat insulation effect of the cement is further improved by adding the materials of fly ash, gypsum and asbestos wool with low thermal conductivity.

Description

technical field [0001] The invention relates to the field of cement. More specifically, the present invention relates to a thermal insulation cement and a manufacturing method thereof. Background technique [0002] At present, the heat insulation function of building construction is the top priority of energy saving and environmental protection work. The current method is to add a layer of heat insulation layer to the outer wall of the building to achieve the effect of heat insulation. The material used for the heat insulation layer is polystyrene foam layer or heat insulation paint. Although the polystyrene foam layer has a certain heat insulation effect Effect, but its construction is complex, high cost, not durable and difficult to maintain, and the heat insulation effect of heat insulation coating is too poor. In fact, the cement used in the building itself is a kind of heat insulation material, but its heat insulation effect is not good. Therefore, changing the cement...

The current method is to add a layer of heat insulation layer to the outer wall of the building to achieve the effect of heat insulation. The material used for the heat insulation layer is polystyrene foam layer or heat insulation paint. Although the polystyrene foam layer has a certain heat insulation effect effect, but its construction is complex, costly, not durable and difficult to maintain, and the heat insulation effect of heat insulation coating is too poor

In fact, the cement used in the building itself is a kind of heat insulation material, but its heat insulation effect is not good. Therefore, changing the cement structure and improving the heat insulation effect of cement can not only meet people's needs, but also the construction process is simple. topics worth studying
