Abstract

The invention discloses a decomposition-resistant PS conductive masterbatch. The decomposition-resistant PS conductive masterbatch includes the following raw materials by weight percentage: 5-10% of superconducting carbon black, 30-60% of high-impact polystyrene, toughened 18 to 30% of antioxidants, 3 to 9% of reinforcing agents, 0.2 to 0.8% of coupling agents, 0.2 to 1.2% of antioxidants, 0.2 to 1.2% of EBS, and 3 to 8% of EMA. In the present invention, superconducting carbon black is used as the conductive carrier, high impact polystyrene PS is used as the base material, and compound toughening agent, reinforcing agent, coupling agent, antioxidant, EBS and EMA are respectively used as lubricants. , dispersant and compatibilizer are compounded according to the appropriate ratio, and the obtained decomposition-resistant PS conductive masterbatch has excellent high temperature resistance and physical and mechanical properties; the decomposition-resistant PS conductive masterbatch can not only be used in polycarbonate and other needs The antistatic materials produced by high temperature co-extrusion can also be used in corresponding conductive and antistatic packaging materials such as electronics, electrical appliances, communications, aerospace, etc., to achieve safe and effective ESD protection for packaged electronic products.

Description

technical field

[0001] The invention relates to the technical field of plastic conductive masterbatch, in particular to a decomposition-resistant PS conductive masterbatch. Background technique

[0002] PS conductive masterbatch, the product uses polystyrene resin as matrix, conductive carbon black with high oil absorption value and ultra-fine particle size as conductive interface, block copolymer thermoplastic elastomer to increase toughness, dispersant, internal and external lubricants Adjusting the melt index of the masterbatch, combined with rigid particle reinforcement and compatibilizer compatibilization, a high-conductivity masterbatch developed by a specific process of single and twin-screw multi-polymerization and secondary extrusion, the product's melting strip resistance reaches 10 3～4 Ω, the forming resistance reaches 10 5～9 Ω, can establish a safe and effective ESD protection.

[0003] The inexpensive PS conductive masterbatch reduces the production cost for m...
