Abstract

The invention discloses high-flexibility antistatic synthetic resin and a preparation method thereof. The high-flexibility antistatic synthetic resin comprises a component I and a component II, in the component I, p-allylphenol is grafted on bismaleimide molecules, the steric hindrance of the bismaleimide molecules is increased, so that the distance between molecular chains is increased, the acting force between the molecules is weakened, the flexibility of synthetic resin is effectively improved, and a vinyl chloride monomer is subjected to chain growth on an active node to form polyvinyl chloride, molecular chain winding occurs, a three-dimensional grid structure is formed on the surface of a bismaleimide molecule, toughness loss caused by increase of the distance between molecular chains is made up, a graphite net is formed in the resin through bombardment of graphene particles and becomes a passage for electrostatic loss, and the synthetic resin is endowed with the antistatic characteristic; pits in the surfaces of the pre-modified bismaleimide molecules are filled with the graphene, so that the toughness and the mechanical strength of the synthetic resin are improved while the antistatic property is realized.

Description

technical field [0001] The invention relates to the technical field of synthetic resins, in particular to a highly flexible and antistatic synthetic resin and a preparation method thereof. Background technique [0002] High-performance resin-based composites are mainly composed of high-performance resin matrix and reinforcement materials. A good matrix resin first requires that it can match the reinforcement materials, followed by high heat resistance, toughness and good manufacturability. Bismaleimide resin has good corrosion resistance, high temperature resistance, radiation resistance and moisture resistance. At the same time, bismaleimide resin is also a kind of thermosetting resin, so it has similar fluidity and moldability sex. [0003] However, bismaleimide resin has the disadvantages of high crosslinking density after curing, low toughness, poor fatigue resistance and impact resistance, etc., which limit the application of bismaleimide resin to a certain extent. Th...
