[0034] Beneficial Effects

[0035] The present invention provides an epoxy resin anti-collision, anti-corrosion and wear-resistant material and a preparation method thereof. Compared with the prior art, it has the following beneficial effects:

[0036] (1) The epoxy resin anti-collision, anti-corrosion and wear-resistant material and its preparation method. Graphene oxide itself has a two-dimensional flaky structure, bears a certain load in the epoxy resin matrix and disperses stress. At the same time, the modified zirconium oxide particles have high hardness and strength. The two act synergistically, so that the modified zirconium oxide fills the gaps between the graphene oxide sheets, making the internal structure of the material more compact, reducing the penetration channels of corrosive substances, thereby improving the anti-corrosion and mechanical properties of the epoxy resin; graphene oxide can prevent the expansion of cracks, and the modified zirconium oxide can produce pinning and deflection effects on the crack expansion path. The two work together to consume more energy and significantly improve the toughness of the epoxy resin; graphene oxide can play a lubricating role at the friction interface and reduce the friction coefficient. The modified zirconium oxide can withstand partial wear during the friction process. The two act synergistically, which can effectively reduce the wear rate of the epoxy resin during the friction process, improve the wear resistance, and extend the service life of the material.

[0037] (2) The epoxy resin anti-collision, anti-corrosion and wear-resistant material and its preparation method form chemical bonds and physical entanglements with the epoxy resin by adding anti-corrosion fillers, thereby enhancing the interfacial bonding force, thereby preventing the fillers from separating from the epoxy resin matrix and improving the mechanical properties and stability of the material; and the anti-corrosion fillers overlap and stack each other in the epoxy resin to form a maze-like physical barrier network, which hinders the penetration of corrosive media, oxygen and water vapor, and can be filled in the gaps in the network to make the network denser, effectively extending the diffusion path of the corrosive medium and enhancing the anti-corrosion performance of the epoxy resin.

[0086]

[0087] Anticorrosion test: The test was conducted in accordance with GB / T 1771-2007; the epoxy resin material was coated on the surface of the copper plate, and cured at 160°C for 3h, 200°C for 3h, 230°C for 2h, and 260°C for 2h, and then placed in a salt spray test chamber for anticorrosion performance test at a temperature of 30°C for 720h; the results are shown in Table 2.

[0092] Table 3

[0093]

[0094] like Figure 1 As shown, the graphene sheets before oxidation are tightly overlapped, with a relatively regular shape and a relatively smooth surface; the graphene surface after oxidation has many wrinkles. This is due to the action of potassium permanganate and concentrated sulfuric acid, which makes the surface of graphene oxide have many oxygen-containing groups. These groups destroy the sp2 hybrid orbitals of carbon atoms in graphite and form a large number of sp3 hybrid orbitals. The sp3 hybrid orbitals cannot be in the same plane, thus forming a wrinkled structure. At the same time, the sheets of the wrinkled part of the graphene oxide are stacked into double layers or a few layers, and the number of layers is significantly less than that of graphite, which shows that the graphite has been completely oxidized and peeled off into graphene oxide.

[0095] like Figure 2 As shown, the modified zirconium oxide is more evenly dispersed on the surface of graphene oxide.

The epoxy resin anti-collision, anti-corrosion and wear-resistant material according to claim 4, characterized in that: The preparation method of the modified zirconium oxide is: Add 1.5-4 g of 8-aminopyrene-1,3,6-trisulfonic acid trisodium salt and 10-15 g of nano zirconium oxide to 22-28 mL of anhydrous ethanol, stir evenly, and then ultrasonically disperse for 10-15 minutes; under stirring, heat the water bath to 45-50° C., and add deionized water; after natural precipitation for 24 hours, pour out the supernatant, wash with anhydrous ethanol for 3 times, then wash with deionized water for 3-5 times, and freeze-dry to obtain modified zirconium oxide.

8. A method for preparing the epoxy resin anti-collision, anti-corrosion and wear-resistant material according to claim 1, characterized in that: The method comprises the following preparation steps: Step 1: After the epoxy resin is heated and liquefied, a diluent and a toughening agent are added in sequence and stirred evenly; Step 2: Add anti-corrosion filler and wear-resistant filler, and stir to mix evenly; Step 3: Add defoaming agent, stir evenly, evacuate, mold, and cure in an oven at 50-70°C for 12-24h to obtain epoxy resin anti-collision, anti-corrosion and wear-resistant material.
