Embodiment 1
[0018] A flame-retardant and antistatic double-functional modified polyethylene composite material, the components of which are: 75% polyethylene, 20% compound flame retardant, 3% antistatic masterbatch, and 1.2% polyethylene wax , Tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol 0.5%, tris(2,4-di-tert-butylphenyl) phosphite 0.3%. Wherein, the compound flame retardant is a compound of polysiloxane flame retardant 50wt%, polyphosphate amine (PPA) 30wt% and aluminum hydroxide 20wt%. The antistatic masterbatch is an antistatic masterbatch prepared by blending 70wt% polyethylene resin matrix, 25wt% glyceryl monostearate (GMS) and 5wt% other auxiliary agents. The auxiliary agent is one or a mixture of coupling agent, antioxidant, stabilizer and dispersant.
[0019] Preparation method: (1) Prepare compound flame retardant: Weigh 50wt% of polysiloxane flame retardant, 30wt% of polyphosphate amine (PPA) and 20wt% of aluminum hydroxide according to the weight...
