Embodiment 1

[0027] Add 80g of polyketone resin and 20g of melamine polyphosphate into a high-speed mixer and mix evenly, then add the resulting mixture into a twin-screw extruder for blending and extrusion, and then cool and cut into pellets to obtain a flame-retardant polyketone resin compound Material. Wherein, the rotational speed of the twin-screw extruder is 30rpm, and the processing temperature is 210-218°C. The obtained flame-retardant polyketone resin composite material can pass the V-0 level (3.2mm) of the UL-94 test, and the limiting oxygen index can reach 24.9%.

Embodiment 2

[0029] Add 80g of polyketone resin and 20g of aluminum hypophosphite into a high-speed mixer and mix evenly, then add the resulting mixture into a twin-screw extruder for blending and extrusion, and then cool and cut into pellets to obtain a flame-retardant polyketone resin composite material . Wherein, the rotational speed of the twin-screw extruder is 30rpm, and the processing temperature is 210-218°C. The obtained flame-retardant polyketone resin composite material can pass the V-0 level (3.2mm) of the UL-94 test, and the limiting oxygen index can reach 26.0%.

Embodiment 3

[0031] Add 90g of polyketone resin and 10g of melamine polyphosphate into a high-speed mixer and mix evenly, then add the resulting mixture into a twin-screw extruder for blending and extrusion, and then cool and cut into pellets to obtain a flame-retardant polyketone resin compound Material. Wherein, the rotational speed of the twin-screw extruder is 30rpm, and the processing temperature is 210-218°C. The obtained flame-retardant polyketone resin composite material can pass the V-1 level (3.2mm) of the UL-94 test, and the limiting oxygen index can reach 26.1%.

Abstract

The invention discloses the preparation of a phosphate flame retardant flame retardant polyketone resin composite material. The polyketone resin composite material mainly involves the following components: phosphate flame retardant and polyketone resin. Wherein, the mass fraction of the phosphate flame retardant: melamine polyphosphate MPP and aluminum hypophosphite AHP is 10-20 wt%. The flame-retardant polyketone resin composite material can reach the UL-94V-0 level, the limiting oxygen index value can reach 28.6%, and has excellent flame-retardant performance.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a phosphate flame retardant added to polyketone resin to prepare a halogen-free environment-friendly flame-retardant polyketone resin composite material. Background technique [0002] Polyketone resin (POK), obtained by the copolymerization of carbon monoxide and olefins (usually ethylene and propylene), is a crystalline engineering plastic. This structure endows this engineering plastic with excellent characteristics: high heat distortion temperature, excellent chemical resistance, hydrolysis resistance and fuel resistance, high impact strength, high elasticity, excellent friction resistance and low gas permeability and high barrier properties, etc. Mainly used in automotive, electronics and packaging applications. Such as automotive fuel system and under the hood and various wear-resistant parts; various connectors, plugs, circuit breakers; precision parts ...
