Example Embodiment
[0050] As an optional embodiment of the present invention, the conductive agent includes graphene and / or graphene oxide.
[0051] Graphene and graphene oxide both have good conductivity. Adding them to resin or polymer materials can make the resin or polymer material have a certain degree of conductivity and dissipate the negative charges on its surface. The materials in contact thereby improve the antistatic performance of the resin or polymer material, and at the same time, graphene and / or graphene oxide can also give the resin or polymer material excellent mechanical properties.
[0052] As an optional embodiment of the present invention, the mass ratio of magnesium hydroxide, glass powder, melamine cyanurate and zinc phosphate in the flame retardant is (5-15): (5-15): (0.5-2 ): (1-7), preferably (6-14): (6-14): (0.6-1.8): (1.5-6), more preferably (8-12): (8-12): ( 0.8-1.5): (2-5).
[0053] Typical but non-limiting mass ratios of magnesium hydroxide, glass powder, melamine cyanu...
