Abstract

The invention discloses a preparation method for a polydicyclopentadiene / polyacrylate composite material. The method includes the following steps that cyclohexyl acrylate and hydroxypropyl acrylate are added into dicyclopentadiene, and a mixed solution is prepared; half of the prepared mixed solution is added into an A material tank of an injection molding machine, organic peroxide is added, and after a main catalyst is added, uniform stirring is performed so that a polymeric material A is prepared for use; under nitrogen protection, the other half of the prepared mixed solution is added into a B material tank of the injection molding machine, then, a defoaming agent and catalyst promoter are added, and uniform stirring is performed so that a polymeric material B is prepared for use; and under the condition of inert gas protection, the material A and the material B are blended and subjected to injection molding so that the polydicyclopentadiene / polyacrylate composite material can be obtained. The composite material prepared through the method has higher anti-impacting performance, and the impacting strength of the composite material can be improved to 180-220 J / m from the original 80 J / m or so.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a method for preparing polydicyclopentadiene / modified polystyrene composite materials. Background technique [0002] Polydicyclopentadiene (Polydicyclopentadiene, English abbreviation PDCPD) is a kind of engineering plastics with high impact resistance and high modulus, which is polymerized by monomer dicyclopentadiene under the action of a catalyst. Diene is a by-product with large output in petrochemical ethylene production. [0003] Polydicyclopentadiene engineering plastics are materials with good heat resistance, creep resistance, dimensional stability, shape memory, corrosion resistance, and light weight. They can be used to manufacture various high-performance, high-value-added, High-end fine products. Such as: automobile bumpers, guard plates, side panels, hoods and body shells in the transportation industry; motors, air conditioners and other large ...
