Embodiment 1

[0024] Step (1). 85g polypropylene, 5g calcium carbonate, 0.1g ultraviolet absorber UV-12, 9.9g flame retardant are mixed into 100g compound;

[0025] Step (2). Add the compound to the twin-screw extruder for extrusion. The processing temperature of the twin-screw extruder is 120°C in the feeding section, 150°C in the plasticizing section, 180°C in the homogenizing section, and the temperature of the head is 180°C ; and then draw in cold water in a water bath at 10° C., the draw ratio is 2 times, and cut and granulate with a cutting machine to obtain a polypropylene composite material.

[0026] From Table 1, we can see that the polypropylene composite material prepared in Example 1 has a tensile strength of 32.4 Mpa, an elongation of 64%, an oxygen absorption induction period of 2 min at 200 °C, and a copper clamp test at 150 °C. After 4 days, the tablet was severely brittle and the copper sheet turned green.

Embodiment 2

[0028] Step (1). 84.7g polypropylene, 0.1g alginate-organic phosphonate compound anti-copper agent, 5g calcium carbonate, 0.2g antioxidant 1010, 0.1g ultraviolet absorber UV-12, 9.9g flame retardant The agent is mixed into 100g mixture;

[0029] Step (2). Add the compound to the twin-screw extruder for extrusion. The processing temperature of the twin-screw extruder is 120°C in the feeding section, 150°C in the plasticizing section, 180°C in the homogenizing section, and the temperature of the head is 180°C ; and then draw in cold water in a water bath at 10° C., the draw ratio is 2 times, and cut and granulate with a cutting machine to obtain a polypropylene composite material.

[0030] From Table 1, we can see that the polypropylene composite material prepared in Example 2 has a tensile strength of 34.6 Mpa, an elongation of 66%, an oxygen absorption induction period of 45 min at 200 °C, and a copper clamp test at 150 °C. After 4d, the tablet is not brittle, and the copper ...

Embodiment 3

[0032] Step (1). 84.5g polypropylene, 0.3g alginate-organic phosphonate compound anti-copper agent, 5g calcium carbonate, 0.2g antioxidant 1010, 0.1g ultraviolet absorber UV-12, 9.9g flame retardant The agent is mixed into 100g mixture;

[0033] Step (2). Add the compound to the twin-screw extruder for extrusion. The processing temperature of the twin-screw extruder is 120°C in the feeding section, 150°C in the plasticizing section, 180°C in the homogenizing section, and the temperature of the head is 180°C ; and then draw in cold water in a water bath at 10° C., the draw ratio is 2 times, and cut and granulate with a cutting machine to obtain a polypropylene composite material.

[0034] From Table 1, we can see that the polypropylene composite material prepared in Example 3 has a tensile strength of 35.1Mpa, an elongation of 63%, an oxygen absorption induction period of 53min at 200°C, and a copper clamp test of 4d at 150°C. The back sheet is not brittle, and the copper shee...

Abstract

The invention relates to a polypropylene composite material containing an alginate-organic phosphonate compound copper ion inhibitor and a preparation method of the polypropylene composite material. A polypropylene composite material blend disclosed by the invention comprises 70-90 percent of polypropylene, 0.01-1 percent of alginate-organic phosphonate compound copper ion inhibitor, 0.1-10 percent of inorganic filler, 0.1-0.5 percent of antioxidant, 0.1-0.3 percent of ultraviolet absorbent and 5-20 percent of fire retardant. The preparation method comprises the following steps: proportionally mixing all raw materials to obtain a mixture, then extruding by means of a double-screw extruder, and then performing drawing and cutting and pelleting by means of cold water to obtain granules. According to the preparation method disclosed by the invention, the alginate-organic phosphonate compound copper ion inhibitor is adopted for complexing copper ions to generate high-stability chelate, has strong capability of inhibiting catalytic aging of heavy metal ions and remarkable copper hazard resisting effect, and has the advantages of being good in intermiscibility with resin, being free from migration and pollution, being good in water resistance and oil extraction property, being free from influencing electrical insulation property and other properties of the resin, and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polypropylene composite material and a preparation method thereof, in particular to a polypropylene composite material containing alginate-organic phosphonate compound anti-copper agent used for electric wires and cables and its Preparation. Background technique [0002] In recent years, with the development of electric power and communication industries, the demand for wires and cables is gradually increasing. All kinds of cables and electrical appliances mostly use copper core cables, and their outer insulating coatings are polyolefin plastics, among which propylene copolymers have shown incomparable advantages as other materials in terms of communication cable insulation materials. However, due to the presence of methyl groups and tertiary carbon atoms in polypropylene molecules, it is very susceptible to light or heat aging, especially in the presence of copper ion...
