Abstract
The invention relates to the technical field of alloy materials and discloses a material specially used for a low-smoke, high flame-retardant and low-odor PC (polycarbonate) alloy board and a preparation method of the material. The material is prepared from the following ingredients: 60-85 wt% of polycarbonate, 5-20 wt% of ABS (acrylonitrile butadiene styrene) resin, 1-5 wt% of a toughening agent,1-5 wt% of a smoke suppressant, 2-10 wt% of a flame retardant, 0.1-1 wt% of an antioxidant, 0.1-2 wt% of a lubricant and 0.2-0.5% of an anti-dripping agent; when the halogen-free flame retardant andthe anti-dripping agent are added to enhance the flame resistance of a PC alloy material, the silicon toughening agent is added, black smoke generated during combustion is reduced, and the density ofsmoke during the combustion is reduced. Meanwhile, by adding ABS and MBS (methyl methacrylate-butadiene-styrene), the tenacity of the PC alloy material at normal temperature and low temperature is guaranteed. The materials selected for the alloy material are all low-odor products, so that the finally produced material has a relatively low odor and can meet the requirements of manufacturers in thebus industry.
Description
technical field [0001] The invention relates to the technical field of alloy materials, in particular to a low-smoke, high-flame-resistance, low-odor PC alloy special material and a preparation method thereof. Background technique [0002] PC alloys, especially PC / ABS alloys, are used in automobiles and home appliances due to their unique and excellent properties. Several changes have taken place in the field of passenger vehicles in recent years. Because PC / ABS does not have good flame retardancy and the smoke density is too high when burning, it seriously affects the escape of passengers in passenger cars in the event of a traffic accident. In this context, it is very urgent to develop a PC alloy sheet with low smoke density, high oxygen index and high flame retardancy, which can meet low temperature toughness, high dimensional stability, and good formability. [0003] CN201611239166.4 describes that polyaryl phosphate improves the flame resistance of flame-retardant PC ...
