New fire and flame retardant materials emerging

In recent years, my country's petrochemical fires and fires caused by building thermal insulation materials have attracted widespread attention from the whole society. The research on new fire-resistant and flame-retardant materials has become an urgent problem to be solved. In the future market will emerge.

Non-combustible inorganic/organic composite foam insulation material and non-combustible exterior wall insulation decorative board system

Article 4 of the General Provisions of the "Energy Conservation Law of the People's Republic of China" states that resource conservation is a basic national policy of our country. At present, my country's building energy consumption accounts for more than 27% of the total energy consumption. The task of external wall insulation and energy saving is arduous, and the market development potential is huge. However, the main body of the commonly used organic foam board thin plaster external wall insulation system and polystyrene board large-scale built-in external wall external insulation system is a flammable material. Even after flame-retardant treatment, its combustion performance can only be Achieving Grade B; the existing commonly used thermal insulation systems have contradictions between physical and chemical properties and thermal insulation performance indicators, and the product life, durability and building life are not synchronized. Therefore, the research and engineering demonstration of non-combustible external wall thermal insulation and decoration systems with high combustion grade, low smoke toxicity, good decorative effect, long service life, and compatibility with thermal insulation and decoration is not only an urgent problem to be solved for external wall thermal insulation, but also a fire protection public An urgent problem to be solved in the security field.

Non-combustible inorganic/organic composite foam insulation materials and non-combustible exterior wall insulation and decorative board systems with combustion performance that can reach Class A came into being, which can be used as wall and roof insulation materials, insulation decoration materials, and exterior wall fire insulation Belt, play the function of fire prevention, heat preservation and decoration. Based on the synthesis principle of composite materials, the thermal insulation material realizes the incombustibility of organic-inorganic composite materials; through the hydrophobic treatment process and binder modification treatment, the problems of water absorption and crack resistance of commonly used inorganic thermal insulation materials are solved, and the comprehensive performance is good. , the combustion performance reaches A1 level (GB8624), the smoke toxicity reaches AQ1 level (GB/T20285), and the thermal conductivity is ≤0.052W/(m2K) (GB/T10295). The surface of the decoration system is made of metal aluminum plate, which can be coated with different colors and patterns to achieve the effect of different materials, and the decoration performance is good.

Hydrocarbon fire resistant steel structure fire retardant coating

With the vigorous development of my country's economy, the construction of tunnels, petrochemical bases, offshore structures, offshore platforms, oil storage tank farms and oil and gas fields has entered a period of rapid development, and there is a great demand for high-performance fire protection materials. The fire scene in the above places belongs to hydrocarbon fire. Compared with the common building fiber fire scene, the temperature of the fire scene rises rapidly in a short period of time and lasts for a long time. At the same time, the coatings used in these places are generally used outdoors, so it is very important for fire prevention. The requirements for protective materials are higher.

There are two kinds of hydrocarbon-resistant and fire-resistant coatings that have excellent chemical corrosion resistance, heat resistance, acid and alkali resistance, and are intact in the explosion test: one is an intumescent coating, and the coating is hydrocarbon-resistant High fire-resistant limit (coating thickness 2.27 mm, fire-resistant limit not less than 1.6 hours), high bonding strength, can withstand the influence of high and low temperature cycles, and the coating has good water resistance, acid and alkali resistance, and salt corrosion resistance , excellent flexibility, not easy to fall off, especially suitable for protecting outdoor steel structure buildings in the petrochemical industry; the other is thick paint, which has reliable fire resistance, light weight (dry density of 514 kg per cubic meter), simple structure, Long hydrocarbon fire resistance (coating thickness 23 mm, fire resistance limit not less than 2 hours), good decoration, good weather resistance, heat insulation, heat preservation. It can be used outdoors or in humid environments, especially for industries with hydrocarbon fire characteristics such as petrochemical, oil and offshore platforms.
