Cement-based foam insulation board refers to an insulation board made of foamed cement technology. Cement-based foam insulation board is also called foam concrete insulation board and inorganic fireproof insulation board. It is a lightweight bubble-like thermal insulation material made from ordinary Portland cement, fly ash, foaming agents, admixtures, etc. through compounding, mixing, foaming, cutting and other processes. Its outstanding feature is the concrete interior. form.

production materials

The main material is cement, which is foamed by adding hydrogen peroxide, hard calcium, fly ash and cement foaming agent. Foam cement insulation board is currently the most ideal wall insulation and wall insulation fireproof isolation zone.

The advantages of insulation materials are: low thermal conductivity, good insulation effect, non-flammable, waterproof, strong bonding with the wall, high strength, no toxic radioactive substances, and environmentally friendly.

Cement, powdery hydraulic inorganic cementitious materials. Add water and stir to form a slurry, which can harden in the air or in water with better effect and can firmly bond sand, stone and other materials together. The word is derived from Latin and means gravel and flakes.

The chemical formula of hydrogen peroxide solution is H2O2. Its aqueous solution is commonly known as hydrogen peroxide. It appears as a colorless, transparent liquid. It is a strong oxidizing agent suitable for wound disinfection, environmental and food disinfection.

Hard calcium is produced by the salt-forming reaction of phenol and caustic potassium, followed by carbon dioxide carboxylation and acid precipitation. White crystalline powder, easily soluble in ethanol, ether and acetone. It can be used in organic synthesis to synthesize pesticides, dyes, drugs, preservatives, etc.

Fly ash is fine ash collected from the flue gases after burning coal. Fly ash is the main solid waste emitted by coal-fired power plants. The main oxide components of fly ash in thermal power plants in my country are: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc.


Foam insulation board is a high-performance inorganic insulation material. It is a porous, lightweight, high-performance insulation-grade board made of a variety of inorganic materials.

It is a product with low thermal conductivity, good thermal insulation performance, high temperature resistance, aging resistance, and A1 grade non-combustible products made from organic gelling materials, modifiers, foaming agents and other additives through mixing system, curing system, cutting system and other processes. other devices. Inorganic insulation materials and cement-based foam insulation boards can be widely used in building exterior wall insulation systems.

1. Green and environmentally friendly

Green and environmentally friendly, no irritation, no harmful gas release; no mineral wool floating matter causes damage to human skin and respiratory tract; flue gas toxicity reaches safety level (AQ1), no harmful gas and waste emissions during production, construction and installation, low carbon Emissions; Repeated removal of insulation materials does not produce waste that pollutes the environment.

2. Fireproof and high temperature resistant

The fire-resistant temperature of cement-based foam insulation board can reach more than 1000 degrees Celsius, the combustion performance is A1 level, it is a non-combustible material and has excellent fire safety performance.

3. High thermal insulation

The closed cell rate of cement-based foam insulation board is greater than 97%. The high closed cell ratio significantly reduces air convection heat transfer. The thermal conductivity of cement-based foam insulation board can reach as low as 0.045W/m*k, which is similar to the thermal conductivity of polystyrene board. Basically equivalent, it can meet the needs of building insulation.

4. Low water absorption rate

The cement-based foam insulation board has low water absorption, which ensures that the product will not become moldy in a humid environment, will not affect the insulation performance, and ensures the safety and durability of the product.

5. Lightweight and high strength

Cement-based foam insulation board solves the contradictory technical problems of low density and high strength of materials and achieves relative unity. The density is 180KG/cubic meter, and the compressive strength reaches more than 0.2MPa, which meets the strength requirements during transportation and engineering applications.

6. Long life and aging resistance

Generally speaking, the service life of organic insulation panel systems is 25 years. When their service life reaches the end of their life, thick buildings require a second or third re-insulation. The service life of cement-based foam insulation panels is more than 50 years, which can be synchronized with the life of the building. The building only lasts a lifetime. Insulated structures are required.

7.Good overheating integrity

After technological improvements, the fire resistance limit of the cement-based foam insulation board has reached more than 3 hours, and it always maintains good fire protection integrity. It will not pulverize after encountering fire and its integrity will be maintained well.

8. Freeze-thaw resistance

Cement-based foam insulation board is a new type of insulation material obtained by our company's R&D team after improving existing foam cement products. The product has undergone 25 consecutive freezing and thawing experiments, and the quality loss rate is small.
