[embodiment]
Below in conjunction with embodiment the present invention is done detailed explanation:
Wherein component one is the bisphenol A-type aromatic copolycarbonate, and relative molecular weight is 25000-30000.The present invention selects for use Japan to go out photochemical IR2200.
Component two fire retardants are brominated triazine, and it is the collaborative BACN of a kind of bromo-nitrogen, and its ultra-violet radiation resisting and light fastness are superior, have overcome the shortcoming that tetrabromo and ten bromine light fastness are poor, color is prone to flavescence, are the upgrading substitute products of tetrabromo and ten bromines.Its outward appearance is pure white, and molecular weight is big, complex structure; Have good thermostability and electric property, superior photostabilization, brominated triazine is different from traditional bromide fire retardant; Its initial decomposition temperature is high, because its fire retardant mechanism removes thermal endothermic decomposition heat drop type, does not contain free bromine simultaneously; The agent of traditional bromine fire-retardant then can produce free bromine, and the negative impact that can avoid free bromine to bring for processing units and environment can make that processing units is safer, product properties is more excellent.Owing to bromine nitrogen flame retardant synergistic effect, its flame retardant resistance is more superior than tetrabromo and ten bromines simultaneously.The application selects the FR-245. of Shandong China ink sharpening for use
Component three fire retarding synergists are a kind of polytetrafluorethylepowder powder of special modification.Component three fire retarding synergists are surface cladding type products, and elite SAN coating material and general-purpose plastics have the better consistency and the transparency.Among the SAN, the mass ratio of vinylbenzene S and vinyl cyanide AN is 4: 1.The mass ratio of PTFE and SAN is 7: 3.Because good consistency, the influence of impact intensity is fewer in the high-impact prescription.Make an addition in the prescription of thermoplastics, can significantly increase melt strength and Young's modulus, play the flame-retardant anti-dropping effect; Make thermoplastic material reach higher flame-retardant standard; Have fabulous dispersiveness, not conglomeration under the normal temperature, injection-molded item is wrinkle resistant; The black and white goods do not have brilliant point, and the improvement of product surface glossiness is especially obvious.Utilize the fibrosis performance of fluoropolymer in plastic working, play anti-drip effect, reduce spreading of flame.The present invention selects the anti-dripping agent Dyneon TF-1645 of Minnesota Mining and Manufacturing Company for use.
