Material used for manufacturing foam cement, method for preparing foam cement from same, and foam cement

Abstract

The invention relates to a foamed cement material and a production and a preparation method thereof. The foamed cement material comprises the following components in parts by weight: 32 to 58 parts of cement, 10 to 34 parts of solid waste materials, 2 to 7 parts of foamed hole conditioning agents, 0.2 to 0.5 part of foamed hole wall reinforcing agent, 2.5 to 7 parts of foaming agents, 0.1 to 0.5 part of foaming speed conditioning agent, 0.1 to 1 part of curing speed conditioning agent and the balance of water, wherein the content of all the components reaches 100% after proper amount of the water is added. The foamed cement is an inorganic heat preservation material with the integrated performance of fire prevention and energy conservation. The foaming ratio of the foamed cement material can be regulated by using the foamed hole conditioning agents, so that the heat conductivity coefficient of the foamed cement material is controlled in a definite range. Therefore, the foamed cement material can satisfy the heat preservation and thermal insulation requirements in cold areas and other areas hot in summer and warm in winter. The foamed hole wall conditioning agent, the foamed hole wall reinforcing agent, the foaming agents, the foaming speed conditioning agent and the curing speed conditioning agent are prepared into solutions, so that the transportation and the category of metering equipment are reduced, i.e. the equipment investment is lowered and the dust emission is reduced. As a result, the sanitary production is realized, and the environment-friendly requirement is satisfied.

Description

technical field [0001] The invention relates to a material for manufacturing foamed cement, a method for preparing foamed cement by using the material and a finished foamed cement product manufactured by using the material or method, and belongs to the technical field of thermal insulation core materials for buildings. Background technique [0002] External wall insulation is an important link in building energy-saving projects. External wall insulation materials need to have high fire resistance, moisture resistance, sound insulation and durability. Traditional external wall insulation materials are mainly organic insulation materials represented by polystyrene (benzene board). However, the above-mentioned organic insulation materials are poor in environmental protection and durability. Therefore, in order to improve environmental protection and durability, in recent years, People have applied the insulation core material made of foamed cement material to the outer wall of ...

AI Technical Summary

Problems solved by technology

However, the foamed cement insulation material disclosed in this document only considers the porosity of the material, and does not consider the closed porosity that affects the above-mentioned comprehensive properties of the foamed cement material. When the selection of additives for speed and curing speed does not match or the foaming speed of cement does not match the curing speed, it will cause the adjacent single holes in the foamed cement to become through holes, resulting in foamed cement. The closed porosity inside the material decreases. At this time, although the foamed cement material has a high porosity, its comprehensive performance is still not ideal.
