Flame-retardant master batch with double-layer strip-shaped structure

The utility model discloses a flame-retardant master batch with a double-layer strip-shaped structure, which comprises a conical plastic protective shell, a conical head is formed on the lower surface of the plastic protective shell, a groove is arranged on the side surface of the plastic protective shell, a cavity is formed in the plastic protective shell, a flame-retardant material is filled in the cavity, and the flame-retardant material is filled in the plastic protective shell. Cylindrical plastic particles are fixedly connected to the interior of the flame-retardant material. According to the utility model, the conical head is designed to destroy the tension of the liquid level and improve the layering effect, the groove and the thin wall are designed to realize different melting rates of different surfaces and achieve the purpose of enabling the surfaces to be more uniform, and the cylindrical plastic particles and the cavity are designed to form a uniform structure. The purposes that the contact area
