Abstract

The invention relates to a preparation method of heat insulation anti-noise foamed cement products. The method takes ordinary Portland cement as base cementing material, coal gangue and nano nickel-zinc ferrite as doping material and straw an additive; the method comprises the steps of preparing a foaming agent water solution by adopting a physical foaming method, evenly mixing the raw materials, then putting the mixture into a foaming machine, foaming and casting to obtain the products. After the technical scheme is adopted, the foamed cement products which are light in weight, high in strength, good in fire-proof property and heat insulation performance and anti-noise can be provided; the foamed cement products can be widely applied to the building industry and related industries, and are capable of effectively improving the fire-proof property and the noise resistance of the inside wall and the outside wall of a building.

Description

technical field [0001] The invention relates to the technical field of a method for preparing foamed cement with light-weight refractory and thermal insulation properties, in particular to the use of interior and exterior walls of buildings. Background technique [0002] About 90% of my country's building exterior wall insulation materials are organic insulation materials, which have poor fire resistance and cannot meet the requirements of fire protection. At the same time, electromagnetic pollution has become a major public hazard and is increasingly interfering with people's normal life. The foamed cement product developed by the invention has good properties of light weight, heat preservation, fire resistance and electromagnetic interference resistance, can well solve the above problems, and can be used as heat preservation material for the inner and outer walls of buildings. [0003] During the research and practice of this method, the inventors of the present invention ...
