Abstract

The invention discloses a novel non-halogen flameproof polypropylene material comprising the constituents (by weight ratio) of, homopolymerized polypropylene powdered material 40-80, ammonium polyphosphate 2-50, melamine phosphates 10-40, pentaerythritol 1-10, drip-proof agent 0.1-2, anti-oxidant 0.1-0.3, coupling agent 0.1-0.3.

Description

1. Technical field: [0001] The invention relates to the technical field of flame-retardant polypropylene materials, in particular to a novel halogen-free flame-retardant polypropylene material. 2. Background technology: [0002] At present, most of the deflection yoke frames of color picture tubes used in color TV sets are made of flame-retardant polypropylene materials. Flame retardant, supplemented by antimony trioxide auxiliary flame retardant, although it has a good flame retardant effect, such materials release a large amount of toxic and harmful gases such as dioxin and Substances that cause poisoning to site personnel and pollution to the environment. With the further strengthening of people's awareness of environmental protection in recent years, more and more attention has been paid to the negative effects of plastic products made of halogen-containing flame retardants in fires. In order to meet the environmental protection requirements of the home appliance indust...
