Embodiment 1

[0026] Add 73wt% of ABS resin and 5wt% of ABS-g-MAH to a high-speed mixer for mixing. After mixing evenly, add them to a twin-screw extruder for melt blending and extrusion, and control the temperature range of the extruder to 170°C. After extrusion, it is cooled to normal temperature in a water tank, pelletized by a pelletizer, and then the obtained pellets are put into an oven at a temperature range of 80°C and dried for 3 hours to obtain modified ABS particles; the modified ABS particles are mixed with carbon black and nickel-plated carbon fiber 10wt%; simultaneously added to a single-screw extruder for extrusion (barrel temperature: 215°C, screw speed 25r / min), weighed about 12 grams of the mixed material at 200°C. Samples of 70×3mm were molded. Then cut out 40×8×3mrD splines from the prepared samples for the test of electrical properties. The test results show that the resistivity of the material is 3.6×10 4 Ohm, apply a DC voltage of 1000V to the composite material, an...

[0028]Add 80wt% of ABS resin and 5wt% of ABS-g-MAH to the high-speed mixer for mixing. After mixing evenly, add them to the twin-screw extruder for melt blending and extrusion, and control the temperature range of the extruder to 200°C. After extrusion, it is cooled to normal temperature in a water tank, pelletized by a pelletizer, and then the obtained pellets are put into an oven at a temperature range of 90°C and dried for 4 hours to obtain modified ABS particles; the modified ABS particles are mixed with polypropylene Nitrile-based carbon fiber 10wt%; simultaneously added to a single-screw extruder for extrusion (barrel temperature: 215°C, screw speed 25r / min), weighed about 12 grams of the mixed material at 200°C. Samples of 70×3mm were molded. Then cut out 40×8×3mrD splines from the prepared samples for the test of electrical properties. The test results show that the resistivity of the material is 3.7×10 4 Ohm, apply a DC voltage of 2000V to the composite material, an...

Embodiment 3

[0030] Add 73wt% of ABS resin and 5wt% of ABS-g-MAH to the high-speed mixer for mixing. After mixing evenly, add them to the twin-screw extruder for melt blending and extrusion, and control the temperature range of the extruder to 210°C. After extrusion, it is cooled to normal temperature in a water tank, pelletized by a pelletizer, and then put the obtained pellets into an oven at a temperature range of 90°C and dried for 4 hours to obtain modified ABS particles; the modified ABS particles and carbon fiber 10wt % at the same time added to a single-screw extruder for extrusion (barrel temperature: 215°C, screw speed 25r / min), weighed about 12 grams of the mixed material at 200°C. Samples of 70×3mm were molded. Then cut out 40×8×3mrD splines from the prepared samples for the test of electrical properties. The test results show that the resistivity of the material is 3.1×10 4 Ohm, apply a DC voltage of 3000V to the composite material, and apply the voltage for 200s. The te...

Abstract

The invention provides an environment-friendly composite material with comprehensive properties. The composite material is characterized by being composed of the following components: 50 to 80 wt% of ABS resin, 5 to 10 wt% of ABS-g-MAH, 5 to 10 wt% of phosphorus flame retardant, 5 to 10 wt% of nitrogen flame retardant, 3 to 5 wt% of silicon synergistic agent, 10 to 15 wt% of conductive filling material, 0.5 to 1.5 wt% of flexibilizer, 0.5 to 0.8 wt% of lubricant, and 0.5 to 1.0 wt% of antioxidant. The provided composite material can improve the flame retardant efficiency of a halogen-free flame retardant ABS material, moreover, the released toxic gas during the burning process is reduced, and the composite material is a low-smoke material with low toxicity. The workability and mechanical properties of the composite material are not changed, the conductivity and impact resistant strength of the composite material are improved, and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention belongs to the field of composite material processing, and in particular relates to an environment-friendly composite material with comprehensive performance. Background technique [0002] ABS resin is a blend of acrylonitrile-butadiene-styrene copolymer or acrylonitrile / styrene copolymer and styrene / butadiene copolymer, which is a graft copolymer of butadiene and acrylonitrile - Mixtures of styrene copolymers comprising 15%-35% acrylonitrile, 5%-30% butadiene and 40-60% styrene. As the ratio of the three components changes, the physical and mechanical properties of the ABS resin change accordingly. ABS resin is a thermoplastic polymer material with high strength, good toughness, heat resistance, low temperature resistance, chemical corrosion resistance, excellent mechanical strength and electrical properties, and easy processing and molding. ABS is widely used in automobiles, electronic appliances, building materials, packaging, sport...
