Description

technical field [0001] The invention relates to a halogen-free flame-retardant composite material and a preparation method thereof, in particular to a polypropylene / thermoplastic polyurethane elastomer halogen-free flame-retardant composite material and a preparation method thereof. Background technique [0002] As one of the five general-purpose plastics, polypropylene (PP) has excellent comprehensive mechanical properties, good dielectric properties and high-frequency insulation and is not affected by humidity. In addition, PP also has high heat resistance. Good chemical performance, hardly absorbs water, and does not react with most chemicals. Because of its excellent comprehensive properties, PP has become an indispensable basic material in our daily life, especially in the fields of household appliances, plastic pipes, high-permeability materials, and wire and cable materials. However, PP also has disadvantages, especially its low impact toughness and flammability. Th...
