Problems solved by technology

[0003] Foamed cement board is a kind of external wall insulation material that is gradually rising at present. It is not easy to age, has the same life as the building, light bulk density, low thermal conductivity, and the fire resistance limit is more than 3 hours. Poisonous gas and other advantages, but the disadvantages of the foamed cement version are also obvious, that is, poor mechanical properties, low strength, high brittleness, very easy to break and damage, which brings great inconvenience to the transportation and construction process

Abstract

The invention discloses a foamed cement composite material with a honeycomb structure and a preparation method thereof. The foamed cement composite material comprises the following raw materials in percentage by weight: 45-75% of silicate cement, 5-25% special cement, 0-10% of fly ash, 1.0-3.0% of water repellent, 0.05-1% of water reducing agent, 2.0-7.0% of composite foaming agent, 0-2.5% of fiber, 0-3% of thickening time control agent and the balance of water. Compared with the traditional foamed cement plate, the foamed cement composite material with a honeycomb structure, prepared by the invention, overcomes the defects of high brittleness, high damage possibility and small size, greatly facilitates the on-site construction of workers, can be used as an excellent warm-keeping / heat-insulating material for energy saving of buildings, and can also be widely used for roofs, floors, inner / outer walls and the like of buildings formed by pouring.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foamed cement composite material with a honeycomb structure and a preparation method thereof. Background technique [0002] The implementation of building energy-saving policies has promoted the development of wall insulation materials. Organic foam plastic insulation materials such as polystyrene and polyurethane are widely used in wall insulation. However, such organic foam plastic insulation materials are extremely flammable. When burning, the fire spreads rapidly and is accompanied by a large amount of poisonous gas and smoke. Serious difficulties in work, resulting in casualties and property damage. At the same time, this type of insulation material also has disadvantages such as easy aging and poor dimensional stability. Compared with organic foam insulation materials, inorganic insulation materials have the advantages of good fire resistance, small deformation coeffic...
