Problems solved by technology

However, due to the active chemical properties of silver ions in silver-based antibacterial agents, they are more sensitive to light and heat, and are easily converted into brown silver oxide or black elemental silver, causing discoloration problems; and PC itself is more sensitive to metal ions, that is, metal Ions cause PC product shock drop

Abstract

The invention relates to a high-strength high-toughness antibacterial mildew-proof flame-retardant PC/ABS alloy material and a preparation method thereof. The flame-retardant alloy material is prepared from the following raw materials in percentage by mass: 60%-75% of PC resin, 5%-15% of ABS resin, 8%-18% of a halogen-free flame retardant, 0.1%-1% of an anti-dripping agent, 0.5%-1.5% of an antibacterial agent, 2%-10% of a flexibilizer and 0.5%-2% of other processing aids, an adopted antibacterial and mildew-proof agent is inorganic powder with zinc as an active component. The high-strength high-toughness antibacterial mildew-proof flame-retardant PC/ABS alloy material provided by the invention is high in notch impact strength, has excellent strength and processing fluidity, has a flame retardant rating of UL94@1.5-3.2 mm V0, has long-term and efficient antibacterial and mildew-proof effects, and can be widely applied to the communication industry, the automobile traffic industry, the household appliance industry and the like.

Description

technical field [0001] The invention relates to an alloy material and a preparation method thereof, in particular to a high-strength, high-toughness antibacterial, mildew-proof, flame-retardant PC / ABS alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (Polycarbonate, PC) is an amorphous thermoplastic engineering plastic with excellent performance, which has good transparency, weather resistance, dimensional stability and excellent mechanical properties; but it also has poor processing fluidity and is prone to stress cracking And defects such as notch sensitivity. Styrene-butadiene-acrylonitrile terpolymer ABS has good processability and is not sensitive to notch, but its weather resistance and heat resistance are not good. The PC / ABS alloy combines the advantages of the two materials, not only has good processing performance, but also has greatly improved heat resistance, weather resistance and stress crack resistance.
