Polyurethane flame retardant
The addition of polyurethane flame retardants in the polyurethane matrix is separated from the polyurethane matrix and its reaction material. Additive type flame retardant is a kind of polyurethane foam fire retardant, which has liquid and solid flame retardant.
The stability of liquid flame retardants of polyurethane in flame retardants is poor, and the flame retardancy decreases with time. However, the selection range is wide and easy to use, and the reaction of polyurethane foam is relatively small and relatively economical, and the process is simple, so it is still an important flame retardant of PUF.
The inorganic flame retardants used in polyurethane flame retardants are generally filled with inorganic compounds into polyurethane matrix, which are decomposed after heat and absorb a large amount of heat to achieve flame retardant purpose. The advantages of inorganic additive flame retardants are low toxicity, low volatility, good thermal stability, no precipitation, persistent flame retardant effects, low price and low smoke content; The disadvantage is that the amount and particle size of this type of flame retardant can affect the flame retardancy and physical properties of the material, and it can lead to a decrease in the performance and physical properties of the polymer.
This kind of flame retardant is commonly solid, has the strong polarity and hydrophilic, with nonpolar polymer compatibility is poor, with polyurethane matrix interface effect is poorer, difficult to form good combination and adhesive. Some flame retardant if added to the polyurethane matrix directly, will seriously affect the foam flame retardant effect, need for this type of flame retardant for chemical processing, such as surface modification, ultrafine, macromolecular bonding processing, thus to reduce consumption, reduce the amount of smoke and flame retardant foam plastics performance.
Soft polyurethane foam vinegar, referred to as "soft foam polyurethane vinegar or cool polyamine soft foam, is has certain flexibility, resilience, permeability, bubble hole for more open groove, and deformation is reversible and have a cool load resistance of polyurethane foam plastic, it is one of the largest a poly dosage of ammonia in the cool products, mainly used for household mattresses, cushion material, vehicle seat cushion, etc.
Cool rigid polyurethane foam plastics, hereinafter referred to as hard foam polyurethane rigid cool or get together ammoniac cool, is better than high strength, light weight, low thermal conductivity, good effect of heat insulation, sound insulation sex good, bubble hole is close pass more, ability, larger load and the load is too large deformation irreversible polyamine cool foam plastics. Usage of hard foam in polyamine cool product to less than soft foam, but compared with other plastic foam, dosage is bigger, its craft is simple, construction is convenient, and expand the application range of it in construction and insulation industry.
