Abstract

The invention provides a soaking-resistant weather-resistant halogen-free flame-retardant polypropylene material, a preparation method and application thereof. The halogen-free flame-retardant polypropylene material is prepared from the following raw materials by mass: 55-75 parts of polypropylene resin, 30-38 parts of a halogen-free flame retardant, 0-6 parts of filler, 0-10 parts of glass fibermaster batch, 0.5-0.8 part of a lubricant, 0.5-1.2 parts of an antioxidant and 0.5-1 part of a light stabilizer; wherein the halogen-free flame retardant comprises piperazine pyrophosphate and melamine polyphosphate. The halogen-free flame-retardant polypropylene material has high flame retardancy, does not fail in flame retardancy after being soaked in water at 70DEG C for 7 days, has mechanicalproperties maintained up to 90% or more, and has the flame retardancy maintained after being exposed to irradiation by a xenon lamp for 1000h, and the mechanical properties are maintained up to 90% ormore, and passes through the 2.0mm thickness UL94-5VA test. Also the preparation method is simple and easy to control, and the soaking-resistant weather-resistant halogen-free flame-retardant polypropylene material can be used for electric appliance parts with a fireproof grade of UL94-5VA.

Description

technical field [0001] The invention belongs to the field of polymer modified materials, and in particular relates to a water immersion-resistant and weather-resistant halogen-free flame-retardant polypropylene material and a preparation method and application thereof. Background technique [0002] Polypropylene is one of the five general-purpose resins. It has excellent properties such as light weight, easy processing, and chemical resistance. It is widely used in chemical, electrical, packaging and other industrial fields. However, with the increasing demand for polypropylene in industries such as construction, automobiles, ships, and electrical and electronic insulation materials, people's requirements for its flame retardancy are also increasing. Polypropylene itself is a flammable material, its oxygen index is only 17% to 18%, and its carbon formation rate is low, and it is easy to produce molten droplets when burning, which will cause the surrounding combustibles to ig...
