Abstract

The invention discloses a high-voltage breakdown resisting halogen-free precipitate-free antiflaming PP (Polypropylene) for electronic/electric apparatus components, comprising the following components in percentage by weight: 57.5-97.4% of PP, 0.2-0.5% of coupling agent, 2-10% of halogen-free flame retardant, 0.2-1% of antioxidant, 0-30% of filler, and 0.2-1% of lubricant. The breakdown voltage of the high-voltage breakdown resisting halogen-free precipitate-free antiflaming PP for electronic/electric apparatus is higher than 4000V and the ball pressure values thereof are all below 2mm, which meet the breakdown resisting voltage requirement of the electronic/electric apparatus components; in addition, the antiflaming effect is good, the antiflaming level is up to V2, and the prepared products have precipitation resistance.

Description

technical field [0001] The invention relates to a halogen-free non-precipitation flame-retardant polypropylene for high-voltage breakdown-resistant electronic and electrical components. Background technique [0002] The components of the electronic and electrical industry mainly include deflection skeletons, output transformer skeletons, switch connectors, refrigerators, washing machine motor end shells, etc. When these components are in poor contact or short circuit, they will cause local overheating and may cause combustion, endangering safe operation of the entire system. Therefore, in 2009, the white goods industry proposed that the glow wire ignition temperature of the material used must be above 750°C in three thicknesses of 3.0mm, 1.5mm, and 0.75mm. At the same time, the high-voltage breakdown voltage must be greater than 4000V, and the ball pressure must be less than 2.0mm. [0003] At present, the plastics used in electronic appliances are mainly PBT, PA, PP, and ...
