Problems solved by technology

Chinese patent CN00820086.6 discloses a polypropylene resin composition containing a halogenated flame retardant additive. The material can still maintain excellent flame retardancy after long-term outdoor exposure and hydrothermal dipping treatment, even when the thickness is thin. It shows good flame retardant performance, but when it burns, it generates a large amount of smoke and produces a large amount of toxic and corrosive gases, causing so-called "secondary pollution", which brings great difficulties to fire extinguishing, escape, and recovery work
Static electricity also damages product quality, for example, polymers affect the quality of materials due to electrostatic adsorption of dust or moisture

Description

technical field [0001] The invention belongs to the technical field of polymer modification and processing, and relates to a flame-retardant and antistatic high-strength thermoplastic composite material and a preparation method thereof. Background technique [0002] In reinforced thermoplastic resin composite materials, due to their high strength and good comprehensive mechanical properties, some aspects are replacing steel, which is the so-called "substituting plastic for steel". However, in the existing reinforced thermoplastic resin composite materials, because the improvement of the resin performance is not considered, its rigidity, bending strength, tensile strength, and impact strength cannot fully meet the requirements, and it is often used in reinforced thermoplastic composite materials. Meet flaw barriers of flammable fire and static hazards. [0003] At present, some flame retardants are often added in the use of plastics, and the flame retardancy is indeed improv...
