本发明公开一种包覆硅树脂的可膨胀石墨阻燃超高分子量聚乙烯的制备方法。本发明通过在可膨胀石墨表面包覆一层硅树脂，利用硅树脂与可膨胀石墨的协同阻燃性质，一方面提升了可膨胀石墨的阻燃性能，降低了阻燃剂的使用量，另一方面提高了超高分子量聚乙烯与可膨胀石墨之间的相容性，增加可膨胀石墨与超高分子量聚乙烯基体的相互作用，解决阻燃剂导致基体力学性能劣化的问题。

The invention discloses a silicon resin coated expandable graphite flame-retardant ultrahigh molecular weight polyethylene preparation method. According to the present invention, the surface of expandable graphite is coated with a layer of a silicon resin, and due to the synergistic flame retardant property of the silicon resin and the expandable graphite, the flame retardant performance of the expandable graphite is increased so as to reduce the consumption of the flame retardant, and the compatibility between the ultrahigh molecular weight polyethylene and the expandable graphite is improvedso as to increase the interaction between the expandable graphite and the ultrahigh molecular weight polyethylene matrix, such that the problem that the of the flame retardant causes the deterioration of the mechanical property of the matrix can be solved.
