The invention discloses a high-strength antistatic composite material sheet. The high-strength antistatic composite material sheet comprises composite material outer structure layers and a conductive core layer. The conductive core layer is located between the upper and lower outer structure layers. The outer structure layer is prepared from unsaturated polyester resin, methyl ethyl ketone peroxide, cobaltous naphthenate, modified graphene and a glass fiber cloth through compounding. The conductive core layer is prepared from unsaturated polyester resin, methyl ethyl ketone peroxide, cobaltous naphthenate, organized copper powder, carboxyl-terminated liquid nitrile rubber, dibutyl phthalate and a glass fiber mat through compounding. The preparation method is convenient. The traditional composite material molding technology can be used for production and processing without improvement. In production, a degree of mechanization is high, labor is reduced and a production cost is low. The high-strength antistatic composite material sheet has good mechanical properties, conductive performances and antistatic performances, can be used at a high temperature for a long time, has large rigidity and creep resistance, does not produce deformation, has good designability and can be used for petrochemical engineering and metallurgy occasions with high-strength antistatic composite material sheet use demands and high strength and antistatic performance requirements.

The invention discloses a calcium naphthenate-zirconium-based polyurea grease, which comprises: 10-70% by weight of non-Newtonian calcium naphthenate; 1-10% by weight of zirconium of higher fatty acids, based on the weight of the grease Salt; 1-15% by weight of small molecule inorganic acid and / or zirconium salt of lower fatty acid; 0.5-30% by weight of polyurea compound; 10-80% by weight of base oil, wherein the zirconium salt of higher fatty acid is made of high-grade Fatty acid reacts with component A, zirconium salt of small molecular inorganic acid and / or lower fatty acid is formed by reaction of small molecular inorganic acid and / or lower fatty acid with component A, component A is oxide of zirconium, zirconium At least one of hydroxide and zirconium alkoxide. The invention also discloses a preparation method of the lubricating grease and the prepared lubricating grease. The lubricating grease of the present invention has better mechanical stability, water resistance and adhesion, salt spray resistance, colloid stability and extreme pressure and anti-wear properties, and has longer lubrication life.
