Abstract

An anti-static flame-retardant PVC / ABS composite material with an isolation structure and a preparation method thereof are provided. The method includes premixing PVC, CPE, an antioxidant, a stabilizer and a plasticizer in a high-speed mixer; raising the temperature of the mixer to 70-90 DEG C; adding a lubricant after the temperature stabilizes; raising the temperature to 90-120 DEG C; then maintaining the temperature for 5-15 min; transferring the mixed material A into a cold feeder and cooling to 40 DEG C or below; subjecting ABS resin and a conductive filler to internal mixing in a torquerheometer for 2-5 min; adding the premixed material A; performing internal mixing for 2-5 min; and molding the material mixture after internal mixing for 5-10 min. The advantages of good mechanical properties and processing performance, extremely high cost performance, wide application, etc. of ABS are utilized, and the PVC / ABS composite material having the isolation structure is prepared throughcontrolling melting time and the like. Problems that ABS has low electrical conductivity and is not flame retardant, which cause problems in user experience, security, etc. are solved.

Description

technical field [0001] The invention relates to the technical field of preparation of composite materials with antistatic and flame retardant effects, in particular to the technical field of preparation of a PVC / ABS composite material with an isolation structure and good antistatic and flame retardant effects. Background technique [0002] At present, the traditional method of preparing conductive and flame-resistant materials is to add fillers, but the random distribution of conductive fillers has a low utilization rate, not only the addition amount is high, but the improvement of electrical conductivity is not obvious, and too much addition will destroy the mechanical strength of the material to a certain extent. [0003] In addition to the method of adding fillers, there are also emulsion blending methods and solution blending methods. However, although the emulsion blending method has strong controllability, designability, and high conductivity, it has high technical requ...
