Abstract

The invention discloses a high glowing filament ignition temperature high-strength polyketone composite material and a preparation method and an application thereof in preparing electronic components.The material is composed of the following materials by weight: 40-80 parts of polyketone resin; 15-30 parts of phenyl ether (PPO); 15-25 parts of hydroxyapatite; 0.5-3 parts of ABS; 0.1-1 part of antioxidant; 0.1-1 part of lubricant. The material is prepared by twin-screw mixing and extrusion. The material has excellent mechanical properties and good toughness and strength. At the same time, thematerial meets the ignition temperature of 750 Deg C or above, and the vertical burning UL-94 V-0 grade, is suitable for internal structural parts of electronics and appliances and particularly suitable for the preparation of electronic components.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-glow wire ignition temperature and high-strength polyketone composite material, its preparation method and its application in the preparation of electronic components. Background technique [0002] Polyketone (Polyketone, referred to as POK) is a linear polymer polymerized from carbon monoxide and polyolefin. It is an engineering plastic with excellent performance, such as high impact strength, wear resistance, and chemical solvent resistance. It can be used in industries, automobiles, and electronic appliances. field. POK molecules are mainly composed of hydrocarbons, the oxygen index is not high, and the flame retardancy is poor, which limits its use in fields with high flame retardancy requirements. [0003] The Chinese invention patent application with application publication number CN107974076A (application number 201711161472.5) discloses a reinforced flam...
