Description
Technical Field
The invention belongs to the technical field of high polymer materials, and particularly relates to a polycarbonate material and a preparation method and application thereof.
Background
Polycarbonate (PC) is the only thermoplastic engineering plastic with good transparency in general engineering plastics, and has a refractive index of 1.585 at normal temperature and a transmittance to visible light of more than 90%. With the increasing development of industries such as automobiles, electronic communication and the like, the requirements on the flame retardant performance of plastic parts of products are higher, the flame retardant grade of the plastic parts of many manufacturers must reach UL 94V-0, and many use occasions also require that PC keeps good light transmittance, so that flame retardant modification is required while the original transparency of the PC is not affected.
Currently suitable flame retardants for transparent halogen-free flame retardant PC systems are sulfonates, phosphates, silicone compounds, and the like. Phosphate flame retardants generally require the addition of very high amounts of materials to achieve the desired flame retardant effect, e.g., bisphenol A-bis-diphenylphosphate (BDP) is added to PC resins to achieve UL 94V-0/3.0 mm, and BDP is used in relatively high amounts, which severely reduces the impact and heat distortion temperatures of the PC. On the basis of not damaging the original performance of PC, many scholars research shows that the optimal flame retardant of transparent halogen-free flame retardant PC is sulfonate, silicone compound or the two compounds, however, the compound system is difficult to stably realize the flame retardant requirement of UL 94V-0/1.5 mm.
Therefore, how to provide a polycarbonate material which can meet the flame-retardant requirement and does not damage the original performance of PC has become a technical problem to be solved at present.
