The present invention relates to a kind of high flow enhuancement flame-retardant PBT material, it is made up of the raw material of following percetage by weight：PBT resin 49 68%, fire retardant 11.5 13.5%, brightener 0 3%, glass fibre 20% 33%, hyperbranched resin 0.2 0.5%, other auxiliary agents 0.3 1%.The preparation method of the high flow enhuancement flame-retardant PBT material is simple：First PBT resin drying is mixed with fire retardant, remaining composition is added and stirs together, finally extrudes and produces with glass in melt extruder.Compared with prior art, beneficial effects of the present invention are, high flow enhuancement flame-retardant PBT material has good heat endurance, 300 DEG C of injections are without precipitation lineae ablicantes, penetrating odor will not be distributed at high temperature heat in addition, surface is smooth, available for the electronic apparatus such as petiole, air outlet grate appearance member and needs the mould of hot flow path one of high fluidity to have more product. |
