[0023] Due to the use of the above technical scheme, the present application has the following beneficial effects:
[0024] (1) The wear-resistant and corrosion-resistant coating disclosed by the present application is made of the following raw materials in parts by weight: bisphenol A type epoxy vinyl resin 25-35 parts, vinyl fluorosilicone oil 5-8 parts, polyether sulfone type hyperbranched epoxy resin 10-15 parts, corrosion-resistant filler 8-12 parts, wear-resistant filler 15-25 parts, coupling agent 3-5 parts, initiator 0.2-0.5 parts, curing agent 10-15 parts, auxiliary agent 3-5 parts, and solvent 20-30 parts. Through the mutual cooperation of the raw materials, the prepared coating has good corrosion resistance, excellent wear resistance, good environmental adaptability, and strong adhesion.
[0025] (2) The wear-resistant and corrosion-resistant coating disclosed by the present application is prepared by synergistically compounding bisphenol A type epoxy vinyl resin, vinyl fluorosilicone oil, and polyether sulfone type hyperbranched epoxy resin, thereby constructing a multi-element cross-linked resin matrix network. The bisphenol A type epoxy vinyl resin lays the foundation for the bonding and mechanical properties, the introduction of the vinyl fluorosilicone oil significantly improves the chemical inertness and weather resistance of the coating, and the branched structure of the polyether sulfone type hyperbranched epoxy resin not only enhances the interfacial bonding force between the matrix and the filler, but also optimizes the cross-linking density and stress dispersion capacity of the coating. The synergistic effect of the three makes the coating not only maintain excellent adhesion, but also break through the technical bottleneck that traditional coatings are difficult to balance wear resistance and corrosion resistance, thereby realizing the simultaneous leap of the two core performances.
[0026] (3) The wear-resistant and corrosion-resistant coating disclosed by the application adopts the corrosion-resistant filler system of glass flake and mica iron oxide compounded according to a specific proportion, wherein the 200-800 mesh glass flake can form a layer-upon-layer 'labyrinth effect' inside the coating, effectively prolonging the penetration path of the corrosion medium, the flaky structure of 5-8 μm mica iron oxide is complementary to the glass flake, further densifying the coating structure; in combination with 1200-1500 mesh high-particle-size silicon carbide powder, corundum powder and other wear-resistant fillers, the high-hardness particles are uniformly dispersed in the resin matrix to form 'rigid support points', which can directly bear the load and reduce the matrix wear when subjected to friction, and the synergistic design of the corrosion-resistant and wear-resistant fillers enables the coating to maintain long-term stable protection performance in harsh environments such as acid and alkali medium immersion, high temperature and humidity, solving the problems of easy blistering and peeling of the traditional coating and rapid attenuation of the protection performance.
[0027] (4) The wear-resistant and corrosion-resistant coating disclosed by the application adopts the curing agent compounded by 2,4-diamino-6-diallyl amino-1,3,5-triazine and 2,2-bis[4-(4-aminophenoxy)phenyl]-1,1,1,3,3,3-hexafluoropropane, the amino and unsaturated alkene in the molecular structure of the curing agent are efficiently reacted with the active groups of the resin matrix, at the same time, the introduction of fluorine elements, phenyl ether and triazine structure further improves the corrosion resistance of the coating, and the synergistic effect of the silane coupling agent can significantly improve the interfacial compatibility of the filler and the resin matrix, avoiding the performance shortcoming caused by the aggregation of the filler; the scientific compounding of the additive system ensures the construction fluidity and film-forming density of the coating, so that the coating can form a uniform and smooth film on the surface of different substrates, further improving the environmental adaptability of the coating.
[0028] (5) The wear-resistant and corrosion-resistant coating disclosed by the application can realize uniform dispersion of each raw material component under simple mixing process, without the need for complex preparation equipment and harsh process conditions, thereby reducing the cost and difficulty of industrial production; through the overall optimization of the resin system, filler combination and curing system, the wear resistance and environmental adaptability of the coating under complex working conditions such as high temperature, strong acid and alkali and high-frequency friction are significantly improved, and the service life of the coating is greatly prolonged, which can effectively reduce the maintenance cost and safety hazard of equipment in the fields of chemical industry, ocean engineering and the like, and has significant technical advantages and application value.
