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 32.4Mpa, an elongation of 64%, an oxygen absorption induction period of 2min at 200°C, and a copper clamp test of 4d at 150°C. The back piece is severely brittle and the copper piece turns green.

Embodiment 2

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

[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 35.1Mpa, an elongation of 74%, an oxygen absorption induction period of 44min at 200°C, and a copper clamp test of 4d at 150°C. The back sheet is not brittle, and the copper sheet has no change. ...

Embodiment 3

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

[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 32.3Mpa, an elongation of 62%, an oxygen absorption induction period of 51min at 200°C, and a copper clamp test of 4d at 150°C. The back sheet is not brittle, and the copper sheet has no change. ...

Abstract

The invention relates to an aminocarboxylic acid-containing organic-inorganic composite anti-copper agent polypropylene composite material and a preparation method thereof. The polypropylene composite material of the present invention is 70-90% polypropylene, 0.01-1% organic-inorganic composite anti-copper agent, 0.1-10% inorganic filler, 0.1-0.5% antioxidant, 0.1-0.3% ultraviolet absorber, 5 Blends of ~20% flame retardants. The method is to mix various raw materials in proportion to form a mixture, extrude the mixture through a twin-screw extruder, and then draw, cut and granulate into pellets through cold water. The method of the present invention uses an organic-inorganic compound anti-copper agent to complex copper ions to form a chelate with high stability, which has a strong ability to inhibit the catalytic aging of heavy metal ions, has a significant anti-copper damage effect and has compatibility with resins. Good, no migration, no pollution, water resistance, good oil extraction, does not affect the electrical insulation properties of the resin and other properties.

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 an aminocarboxylic acid-containing organic-inorganic compound anti-copper agent polypropylene composite material for wires and cables and a preparation method thereof . 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...
