Chemical foaming cement fireproofing heat-preservation structure and preparation method thereof

Abstract

The invention discloses a chemical foaming cement fireproofing heat-preservation structure, which is characterized in that the structure is an insulating layer formed by enabling chemical foaming composition to be poured on a wall face of buildings. Components of the chemical foaming composition comprises 120-180 parts of sulphoaluminate cement, 50-60 parts of coal ash, 7.5-12 parts of hydrogen peroxide, 0.8-1.3 parts of ethenyl ethanoate grease-ethylene copolymer emulsion, 0.5-4 parts of water reducer, 0.3-0.8 parts of polypropylene staple fiber, 3-7 parts of calcium stearate and 28-36 parts of water by weights. The chemical foaming cement fireproofing heat-preservation structure and the preparation method can effectively lowers cost, improve efficiency, reduce labor intensity, avoid a cold and hot bridge formed by pasting the heat-preservation structure and avoid blank drum cracking caused by construction and material faults. The chemical foaming cement fireproofing heat-preservation structure and the preparation method can be widely used in roofs and wall bodies of the buildings, and can well guarantee combustibility, thermal insulation property, water resistance and safety performance of the heat-preservation structure of the wall bodies.

Description

technical field [0001] The invention belongs to a fire-proof and heat-preservation plate component used for the wall surface of a general building and a preparation (construction) method thereof, and relates to a fire-proof and heat-preservation structure of chemically foamed cement and a preparation method thereof. It is especially suitable for forming thermal insulation, fire prevention, waterproof and sound insulation structures on the walls of general buildings (mainly exterior walls, but also interior walls). Background technique [0002] With the full development of my country's building energy-saving work, the demand for building energy-saving materials has increased sharply, and the requirements for the construction, safety and energy-saving effects of energy-saving materials have also become higher and higher; inorganic porous materials are characterized by their excellent environmental protection, practicality, and economy Sexuality has sprung up suddenly in the mar...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the fire-proof and thermal insulation board components of the building wall are generally produced in factories, and the formed products are cut into certain specifications, for example: boards with a length of 300 cm, a width of 300 cm, and a thickness of 30-120 cm, which are transported to the building when used. At the construction site, cement, mortar, etc. are used to paste the board on the building wall (exterior wall or interior wall). In this way, the investment in equipment is large, the loss in production is about 30%, and the construction cost is high. The effect is poor, it is easy to hollow out, fall off, and the thermal insulation effect is poor; in addition, the fireproof and thermal insulation board components on the walls of existing buildings are generally produced in the factory by physical foaming, and physically foamed foam concrete is used as When used as thermal insulation materials, there are problems such as low strength, high water absorption rate, and long setting time, so it is difficult to apply to wall insulation, and the practicability is poor
