Abstract

The invention discloses a flame retardant. The fire retardant comprises, by weight, an iron oxide-based pigment and at least one selected from a halogen-based flame retardant and a halogen-free flameretardant, wherein a weight ratio of the at least one selected from the halogen-based flame retardant and the halogen-free flame retardant to the iron oxide-based pigment is 40: 1 to 2: 1. According to the invention, the iron oxide-based pigment is introduced for compounding with the flame retardant, so the surface smoothness and the density of a formed carbon layer are effectively improved, the oxygen index of the carbon layer during combustion is increased, and the flame retardancy of a polypropylene composite material is enhanced.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials and polymers, in particular to a flame retardant and a polypropylene composite material. Background technique [0002] With the continuous development of science and technology and economy, daily products made of plastic play an increasingly important role in life. However, plastics are easy to burn, and the burning speed is fast, which will produce a large amount of toxic gas, causing casualties and property losses. Therefore, it is required that plastic products do not burn and have good flame retardant properties, and the smoke generation of plastics in large fires is required to be small. However, the properties of flame-retardant plastics currently used cannot meet the requirements. [0003] Halogenated flame retardants are currently one of the most productive organic flame retardants in the world. They are widely used in polyolefin flame retardants due to their remarkable...
