Fire-resistant phenolic insulation board chooses six reasons
in the market of the most common phenolic insulation board, for example, it has low cost, abrasion resistance, scratch resistance, high temperature resistant, resistant to radiation, pollution resistance, impact resistance, easy cleaning, etc, loved by consumers. Phenolic plate is a new kind of non-combustible low smoke, fire insulation materials, it is made of phenolic resin in foaming agent, curing agent and other additives made of closed-cell rigid foam. It is the most prominent feature of non-combustible, low smoke, resistance to high temperature of different change. It overcomes the original type foam thermal insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam thermal insulation material is qualitative light, construction is convenient wait for a characteristic. Traditional phenolic board not only can be used for exterior insulation system, can be also prepared to act the role of surface composite insulation decoration plate, can also be used to build the traditional EPS/XPS exterior wall thermal insulation system fire belt/PU, will be used for fire prevention in the curtain wall thermal insulation materials, fire door insulation materials, as well as low or high temperature of fire insulation material. However, currently on the market, inferior, unqualified phenomenon is also common. Due to the poor quality of phenolic insulation board, reduces the cost, most of them adopt generic foreign crude colored paper, due to the use of ink and quality control is poor, it is easy to fade color paper and color difference phenomenon. In addition, the paper and the kraft paper used by the uniformity of fiber array is poorer, leading to poor flatness of the end product. What's more, due to poor uniformity of the fiber arrangement, internal stress imbalance, causing cracking, lead to products, such as deformation and bubbles. In addition, because of their poor raw materials, equipment and backward technology, its durability is very low. Selection of fire-resistant phenolic insulation board reason:
1, environmental protection: rock wool, glass wool has harm to the environment and people, polyurethane, polystyrene combustion heating will break the toxic gas such as hydrogen cyanide and carbon monoxide. Phenolic insulation board with cfc-free foaming technique, no fiber, conform to the requirements of environmental protection at home and abroad.
2, the sound absorption performance: phenolic insulation board with excellent sound absorption performance, open the bubble structure is more advantageous to sound absorption;
3, low density, light weight, the density of phenolic insulation board under 100 m3, can amount to about 50 m3. It can reduce the weight of the building, lighten the load of the building, reduce the cost of the structure, simple and quick construction, improve the working efficiency.
4, corrosion resistance and aging resistance, resistance to almost all of the inorganic acid, organic solvent. Long-term exposure to the sun, no obvious aging phenomenon, has good resistance to aging performance:
5, excellent thermal insulation performance, low thermal conductivity, 0. 025 WmK, more than double polystyrene, close to pu) Heat preservation and heat insulation, excellent performance;
6, excellent fireproof performance: polyurethane and polystyrene organic insulation materials, such as burns, will produce smoke and toxic substances, easy to cause death, at the same time also increased the difficulty of the fire. But phenolic insulation board is the combustion performance of the highest grade A, the highest working temperature is 180 ℃ ( The instantaneous allow 2 5 0 ℃) , 100 mm thick phenolic foam flame retardant ability can reach more than 1 hour.
