Problems solved by technology

Although inorganic flame retardants meet the requirements of environmental protection, their flame retardant efficiency is not high. The large amount added will seriously deteriorate the mechanical properties of polypropylene, and the gain outweighs the gain.

Abstract

The invention provides a weather-resistant halogen-free flame-retardant polypropylene material as well as a preparation method and application thereof. The weather-resistant halogen-free flame-retardant polypropylene material is prepared from the following raw materials in parts by mass: 55-75 parts of polypropylene resin, 20-38 parts of halogen-free flame retardant, 1-3 parts of a flame-retardantsynergist, 0.5-0.8 part of a lubricant, 0.5-1.2 parts of an antioxidant and 0.3-1 part of a light stabilizer; wherein the halogen-free flame retardant comprises microcapsule ammonium polyphosphate and a charring agent. The weather-resistant halogen-free combustion-supporting polypropylene material has a high flame retardant performance (UL94 V-0 and UL1694 SC-0 with a thickness of 0.75 mm), and after being soaked in water at 70 DEG C for 7 days, at least 90% of mechanical properties are still maintained. After the material is irradiated by a xenon lamp for 1000 hours, at least 90% of mechanical properties are maintained. In addition, the preparation method is simple and easy to control. The material is applied to a soft core of decorative lighting.

Description

technical field [0001] The invention belongs to the field of polymer modified materials, and in particular relates to a 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 ignite, so it is required in man...
