Abstract

The invention discloses a formula of a composite foamed cement board. The formula is obtained by the following step: (1) proportioning the following various components in parts by weight: 16 parts of ordinary portland cement, 18 parts of coal ash, 20 parts of mineral powder, 5 parts of hydrogen peroxide, 2 parts of foam stabilizer, 0.4 part of polypropylene fibres and 0.3 part of excitant; and (2) stirring at a rotational speed of 2800r / min and a slurry temperature of 30-50 DEG C according to the proportion and a water-material ratio of 0.52 by virtue of a stirrer. The formula of the composite foamed cement board disclosed by the invention is capable of overcoming the defects of unreasonable proportion, short service life, low reliability and the like in the prior art, so as to realize the advantages of reasonable proportion, long service life and high reliability.

Description

Technical field [0001] The invention relates to the technical field of cement processing, in particular, to a formula of a composite foamed cement board. Background technique [0002] With the ever-increasing global energy crisis, the vigorous implementation of my country's energy conservation and emission reduction policies, and the in-depth development of building energy conservation, the external wall insulation industry has developed rapidly. [0003] However, external wall insulation boards such as benzene boards, extruded boards, rock wool, and polyurethane insulation boards are widely used. Due to the flammability of the material itself, once a fire accident occurs, it will seriously endanger people's lives and property safety. [0004] Composite foamed cement board, as a new type of building inorganic exterior wall thermal insulation material developed in recent years, is green, environmentally friendly, Class A fire protection, easy to obtain raw materials, high cost perform...
