Hengshui national standard 120KG thermosetting silicon polymer polystyrene board fire rating

Hengshui national standard 120KG thermosetting silicon polymer polystyrene board fire rating Modified fire-resistant resin is a type of resin product produced through chemical reactions between fire-resistant resin, adhesive, and polymer; Modified fireproof resin is used to change the fireproof and flame-retardant properties of polystyrene particles, making them hydrophilic and forming a fireproof isolation film on the surface of the particles, achieving a flame-retardant effect. Modified fireproof resin accelerator（BMaterial: Fireproof resin accelerator is a mixture that controls the curing reaction, reacts chemically with modified fireproof resin, and controls the curing and molding time of fireproof insulation board. modificationEPSFireproof insulation board is a new type of fireproof insulation material, which is made of modified fireproof resin, fireproof resin accelerator, fireproof resin curing agent, polystyrene particles, and fireproof isolation film technologyEPSMonomer particles have the same characteristics as fire-resistant substances, and microphase composite technology is used to form a fire-resistant isolation film on the surface of each organic particle, making each particle form a relatively independent organic particle fire-resistant unit. When encountering flames, it forms a continuous honeycomb structure with thermal insulation and barrier, which blocks the propagation and penetration of flames and prevents combustion from occurring. And on the basis of maintaining the original excellent physical properties of polystyrene board, the modified polystyrene board is improved from thermoplastic to thermosetting, effectively improving the fire resistance of polystyrene board, which can reachA2level

Siliceous polymerized polystyrene board, also known as polymer polystyrene board, is made of ordinary polystyrene particles as the main raw material. After preheating the foam particles, polystyrene raw material is mixed with inorganic fireproof materials, stirred and covered with film. When adding foam board equipment, the product is heated for secondary foam forming. The product reaches A2 incombustible effect, and has the characteristics of low thermal conductivity, fire prevention, waterproof, light weight, high strength, etc. It is the current alternative product of various thermal insulation materials.

In a good bonding system, bonding mortar and plastering mortar not only have high bonding strength with the base layer, surface layer, but also with homogeneous fireproof insulation board.
2. A good anti cracking system is specially added to the plastering mortar with flexible polymers and anti cracking fibers, which have excellent anti cracking performance. The system product not only has a certain degree of elasticity, but also has good compatibility with homogeneous fireproof insulation boards and surface materials, which can form gradient deformation and flexible gradient, thereby ensuring that the system does not crack.
3. In an excellent waterproof system, the plastering mortar not only has good bonding strength with the homogeneous fireproof insulation board, but also has excellent hydrophobicity, waterproofing, and impermeability properties, providing good protection for the wall. 4. Suitable breathable homogeneous fireproof insulation board bonding mortar and plastering mortar are both made of polymer cement materials, which are breathable and impermeable, and have good respiratory performance. 5. Good impact resistance: The homogeneous fire-resistant insulation board has high strength and toughness. Usually, the first floor of a building is easily damaged by impact. In the system construction process, the first floor is coated with two layers of composite alkali resistant fiberglass mesh cloth to ensure excellent impact resistance of the system.

Performance:
1. Silicon polymer polystyrene board can withstand high temperatures of 250-300 ℃ and withstand high temperatures of 400-500 ℃ in case of fire. Polyimide PIIPN is one of the stable and highly stable varieties in polymers
2. Good flame retardancy, heat resistance, no smoke, and no harmful gases produced. It is because amine radicals are good absorbents. During the high-temperature decomposition process, the free radicals generated by the broken sub bridges are quickly absorbed by the amine radicals, preventing the reaction from continuing. This phenomenon makes modified polyimide extremely difficult to burn
3. The low toxicity and low smoke modified PIIPN molecule contains only hydrogen, carbon, and oxygen atoms. During high-temperature decomposition, only products composed of carbon and oxygen can be produced, and there are no other toxic gases except for a small amount of CO. The modified PIIPN has a high pharyngeal capacity of 5%, while the polyurethane has a high pharyngeal capacity of 74%. In comparison, the modified PIIPN has a relatively low pharyngeal capacity
4. The flame penetration resistant modified PIIPN exhibits carbon deposition, no sagging, no curling, and no melting phenomenon under direct flame action. After the flame burns, the foam basically remains, just a layer of graphite foam on the surface of the line, effectively protecting the foam structure of the inner layer. Its flame penetration is very strong.
5. Insulated modified PIIPN has a uniform and fine closed cell structure, and the thermal conductivity after mixing with polystyrene particles is only 0.022-0.040w (mk). Its insulation performance is comparable to that of polyurethane and extrusion
6. The strength of the uniformly modified fireproof insulation board is not significantly affected by temperature and does not undergo cold shrinkage or brittleness at low temperatures of -196 ℃. The mechanical temperature remains basically unchanged. Used within the range of -196 ℃ -130 ℃ *Hengshui national standard 120KG thermosetting silicon polymer polystyrene board fire rating
