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.

Abstract

The invention provides a material for producing foamed cement, a method for preparing foamed cement using the same, and foamed cement, which at least include the following components in parts by weight: 100 parts of cement, 20-80 parts of solid waste materials, foam 1.2-2.5 parts of cell regulator, 0.1-0.5 parts of cell wall strengthening agent, 2.5-15 parts of foaming agent, 0.002-0.023 parts of foaming speed regulator, 0.01-0.5 parts of curing speed regulator, 62-93 parts of water . The material of the foamed cement of the present invention, under the condition of comprehensively considering the factors that may affect the performance of the foamed cement, by adjusting the raw material formula of the foamed cement material, the internal porosity and single-cell closed cell ratio of the finished foamed cement can be obtained. Higher foam cement material. Because the porosity and single-pore closed cell ratio inside the foamed cement are improved, the foamed cement prepared by the foamed cement material of the present invention has low thermal conductivity, good thermal insulation, sound insulation and other performances, and low water absorption.

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 ...
