A kind of high-strength antistatic composite material plate and its preparation method

Abstract

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.

Description

technical field [0001] The invention discloses a composite material plate, in particular to a high-strength antistatic composite material plate and a production method thereof. Background technique [0002] Thermosetting resin-based composite materials use thermosetting resins, including unsaturated polyester resins, epoxy resins, etc. Reinforced material is a kind of composite material made by certain processing technology. It has the advantages of strong designability, anti-corrosion, and convenient processing and molding. The composite material sheet made of it can be widely used in construction, municipal administration, transportation, packaging and other fields. But even so, there are some obvious deficiencies in the use of thermosetting resin-based composite materials. For example, when used in petrochemical, metallurgical and other occasions, it is often required that the board or its products used have high strength and antistatic properties at the same time.

But even so, there are some obvious deficiencies in the use of thermosetting resin-based composite materials. For example, when used in petrochemical, metallurgical and other occasions, it is often necessary for the board or its products to have high strength and antistatic properties at the same time. Deformation or static sparks, and may even explode in severe cases

Plates made of traditional thermosetting resin-based composite materials can have certain antistatic properties and strength properties, but often cannot achieve high strength and high antistatic properties at the same time
