Problems solved by technology

[0004] PC / ABS alloy materials are used in the adhesive field, which requires extremely high bond strength and stability; such as PC / ABS alloy materials used in the field of lead-acid batteries, the initial bond strength is required to be ≧76.2Kgf / 1.27cm 2 ; while the PC / ABS alloy materials currently on the market, the bond strength is mostly 50-70Kgf / 1.27cm 2 ; Can not meet the requirements of the battery field
[0005] Moreover, because PC / ABS materials are poor conductors of electricity, they tend to accumulate static charges during processing and use. When the static charges accumulate to a certain extent, static electricity will cause the material to absorb dust, cause material damage, and may also generate static spark discharge , causing chemical product warehouses to explode and catch fire, resulting in major personal accidents

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antistatic PC / ABS compound, a preparation method and application thereof. Background technique [0002] PC / ABS alloy is an alloy material synthesized by PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene copolymer) in a certain proportion. Polycarbonate (PC) has the advantages of high impact strength, creep resistance, good dimensional stability, heat resistance, transparency, and excellent dielectric properties, but it also has poor processing fluidity, prone to stress cracking, sensitive to notches, and Disadvantages such as poor abrasiveness; acrylonitrile / butadiene / styrene copolymer (ABS) has good chemical resistance and molding processability, but its heat resistance and weather resistance are relatively poor. The PC / ABS alloy obtained by blending and modifying the two can complement each other in performance. Not only the heat resistance, impact str...
