Abstract

The invention discloses a foaming cement heat insulation plate, which belongs to the field of building material technology. The foaming cement warming plate comprises the following components by weight: 150-200 parts of common silica acid cement, 20-30 parts of silicon powder, 40-50 parts of coal ashes, 15-20 parts of hydrogen peroxide, 1-3 parts of polypropylene fiber, 8-12 parts of calcium stearate, 120-150 parts of water and 10-15 parts of reinforced powder. The foaming cement heat insulation plate provided by the invention has good compression strength and aging resistance, and the stability and life of the heat-insulation layer are improved, thereby effectively guarantying flattening and non-cracking of indoor with long life; the product has light weight; the product is made of non-combustible material with A fireproof grade and without pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a foamed cement insulation board. Background technique [0002] Foamed cement is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then go through the pumping system of the foaming machine for cast-in-place construction or mold molding. A new type of lightweight thermal insulation material with a large number of closed pores formed by natural conservation. It belongs to the bubble-like thermal insulation material, and its outstanding feature is that it forms closed foam pores inside the concrete, which makes the concrete lightweight and thermally insulated. Use foamed cement as the insulation layer for roof insulation and wall insulation, replacing other insulation materials such as polystyrene (benzene board), with unparalleled thermal insulation performance and structur...
