[technical field]
The present invention relates to polymeric material field, relate in particular to a kind of fiberglass reinforced fire retardant polycarbonate material and preparation method thereof.
[background technology]
Along with the continuous growth and the continuous advancement in technology in Chinese liquid-crystal display market, the size of liquid-crystal display constantly increases, and has developed into the tenth generation of today from the 4th generation in 2000, and size also increases severely to the 47-60 inch.
Liquid crystal module is the key ingredient of liquid-crystal display, and it combines image display and back light unit.The framework of liquid crystal module, thin thickness, precision size, undersized liquid crystal module framework is because bearing capacity is less, and is less demanding to the rigidity of material.And, its toughness is also had higher requirement along with the increase of liquid-crystal display size.
Spun glass is a kind of common strongthener, behind a certain amount of spun glass of adding, the intensity that makes material is significantly improved in the ordinary resin.Because the low-shrinkage of spun glass reduces the overall shrinkage that makes material, helps keeping the dimensional stabilizing of product.But spun glass is an inorganics, and is poor with the consistency of resin, needs adding coupling agent and compatilizer to wait the consistency of the system of lifting during use usually, thereby obtains the excellent comprehensive performance.
Polycarbonate (PC) is the higher resin of a kind of toughness, add the strongthener spun glass among the PC after, though rigidity is further improved, dimensional stability increases, but the toughness of material descends rapidly, and floating fibre is more, outward appearance is good inadequately.For adapting to the requirement of liquid crystal module framework, must improve the toughness that PC adds fiber material.
Common PC fibre-added fire-retardant system, the fire retardant of use all are common brominated flame retardant.Though its flame retarding efficiency is higher, and some also meets the environmental requirement of ROHS, strict day by day along with environmental requirement; Brominated flame retardant has begun disabled in some occasion; Therefore, the exploitation halogen-free flame retardants is applied to PC fibre-added fire-retardant system, is with a wide range of applications.
