The present invention relates to a non-halogen flame-retardant polypropylene resin composition excellent in flame retardancy, heat resistance and moldability.

Conventionally, a product in which a flame retardant is compounded into a polycarbonate resin is mainly used as a flame retardant insulating film or sheet for electrical / electronic products.

However, the cost of compounding flame retardants in polycarbonate resins is very variable according to supply and demand conditions, the life cycle is very short due to the characteristics of electric and electronic products, and the price of existing products tends to drop due to the latest product models. In addition to domestic and international companies such as LG and LG, overseas electric / electronic product manufacturers have been unilaterally pressured to lower the price of plastic materials used in electric / electronic products as the price of electric / electronic products decreases.

However, polycarbonate resins, whose main raw materials are petrochemicals, have large price fluctuations depending on the production and supply of crude oil, and limited supply and demand, which is very unstable and fluctuating in price fluctuations, especially in China and India. As the market is increasing, it is impossible to keep up with the market flow of electric / electronic products without replacing this resin, and cannot supply stable supply to meet the unit prices required by global home appliances manufacturers.

Accordingly, in recent years, various polyolefin-based resins such as polypropylene resins, which are cheaper than the polycarbonate resins and are easily supplied, have been applied. In addition, in order to impart flame retardancy to polyolefin resins, compounds have been compounded with halogen-based flame retardants until recently.However, halogen-based flame retardants cause environmental problems, and their use is restricted internationally. Items designated as regulated may not be used.

Compounding a metal soap-based lubricant, an amide-based lubricant, polyethylene wax and an inorganic filler has led to the development of a non-halogen flame-retardant polypropylene resin composition excellent in flame retardancy, heat resistance and moldability.
