Embodiment 1

[0022] The raw materials and weight ratio of the mortar are:

[0023] Composite Portland cement 45-65%;

[0024] Vitrified microbeads 34-54%;

[0025] Dispersible rubber powder 0.5-2%;

[0026] Methyl hydroxypropyl cellulose ether 0.1-0.6%;

[0027] Fiber 0.5-1.2%;

[0028] Silicone waterproof powder 0.1-0.4%.

[0029] Specifically, composite Portland cement is a hydraulic cementitious material made of Portland cement clinker, two or more specified mixed materials, and an appropriate amount of gypsum. It is called composite Portland cement. The current grades of composite Portland cement are divided into three types: 325, 425, and 525. Select No. 425 cement for use in the present embodiment.

[0030] Vitrified microbeads (also known as expanded vitrified microbeads) are a kind of acidic vitreous lava minerals. After special technical treatment and production process, they form internally porous, surface vitrified and closed, spherical fine-diameter particles. A new type...

Abstract

The invention relates to the technical field of materials for construction industry, in particular to composite silicate heat preservation mortar. The invention adopts the following technical scheme that the mortar comprises the following raw materials in weight ratio: 45-65 percent of composite portland cement, 34-54 percent of glazed hollow bead, 0.5-2 percent of dispersible rubber powder, 0.1-0.6 percent of hydroxypropyl methyl cellulose, 0.5-1.2 percent of fiber and 0.1-0.4 percent of organic silicon waterproof powder. When in construction carried out by adopting the mortar produced by the technical scheme, an on-site construction mode can be adopted, and water is directly added to the mortar for stirring and then the mortar can be used. The stirred material can be directly constructed to a dry wall body; the construction performance is superior and the construction process is simple; and the construction efficiency can be greatly improved and the construction cost of a construction is reduced.

Description

Technical field: [0001] The invention relates to the technical field of materials used in the construction industry, in particular to a composite silicate thermal insulation mortar. Background technique: [0002] With the continuous deterioration of environmental problems, human awareness of energy conservation is also increasing. Now people are paying more and more attention to energy saving in the building field. Extensive energy-saving buildings refer to following the basic methods of climate design and energy conservation, and after researching building planning zoning, groups and individual units, building orientation, spacing, solar radiation, wind direction and external space environment, the buildings constructed can reduce energy consumption . For example, design, construction, and use should reduce resource consumption; structural materials should have sufficient strength, durability, enclosure structure, heat preservation, waterproof...; use low-pollution materi...
