The invention discloses a conductive fiberglass reinforced plastic material. After ultralow temperature pretreatment is performed on fiberglass through a physical method, the bending resistance and the tensile property of the fiberglass are improved; through high temperature treatment, an original sizing material on the surface of the fiberglass is oxidized to be decomposed, and then water stored and adsorbed in the fiberglass is removed; the surface of the fiberglass is grafted with a modified porous carbon nano tube material through a chemical method; a hole structure is achieved, when the fiberglass is composited with a matrix, chain segments of some high polymers enter holes, a similar anchoring effect is achieved, the binding force betrween the fiberglass and a polymer interface is enhanced, the impact resistance of the product is improved, and the prepared fiberglass reinforced plastic material has the advantages of being good in mechanical property, corrosion resistance and electromagnetic shielding effect.

Example Embodiment

[0012] A conductive polyester glass fiber reinforced plastic material made of the following parts by weight: unsaturated polyester 100, glass fiber 18, carbon nanotube 0.4, carbon fiber 5, silica gel 7, attapulgite 10, barium metaborate 0.2, silane couple Coupling agent KH-5708.5, triethyl aluminum 1.2, stearic acid 6, methyl ethyl ketone peroxide 2, and 1% ethanol aqueous solution are appropriate.
[0013] The manufacturing method of a conductive polyester glass fiber reinforced plastic material includes the following steps:
[0014] (1) Put the glass fiber in ultra-low temperature treatment equipment at minus 100°C to minus 200°C for 10-15 hours, take it out and return to temperature naturally, put it in a muffle furnace at 550-600°C, heat treatment 1-2 Hours, natural reheating to prepare pretreated glass fiber;
[0015] (2) The silane coupling agent KH-570 is ultrasonically dispersed in a 1% ethanol aqueous solution at a volume ratio of 1:50, and the temperature is raised to 80-90°C, and carbon nanotubes and stearic acid are added to keep the temperature and stir for 30-40 minutes. After adding the pretreated glass fiber, carbon fiber, and attapulgite prepared from the materials in step (1), soaking for 2-4 hours, vacuum filtration, drying and grinding the filter residue to obtain modified glass fiber;
[0016] (3) Put the unsaturated polyester into the high-mixer, add barium metaborate and silica gel and mix for 20-30 minutes, then compound with the above-mentioned modified glass fiber and other remaining components, and finally cure in the mold at 75-80°C for 10- 15 minutes, demould and discharge at room temperature.
[0017] The technical parameters of the polyester FRP materials produced by the invention are as follows:
[0018] (1) Tensile strength (MPa): 106;
[0019] (2) The shielding effect of electromagnetic waves can reach 30dB, and the shielding effect is good;
[0020] (3) Compressive strength (MPa): 92.1;
[0021] (4) Impact strength (KJ/m 2 ): 33.1.
