AI Technical Summary

Technical Problem

Existing stainless steel tile surface coating materials suffer from high brittleness of epoxy resin, which makes the coating prone to micro-cracks under alternating temperature differences, allowing corrosive media to penetrate and affecting adhesion and durability.

Method used

Bisphenol F epoxy resin and E51 epoxy resin are used as the film-forming base material, combined with treated hexagonal boron nitride and mica iron oxide and other fillers to enhance the flexibility and barrier properties of the coating. KH550 treatment solution is used to improve the interfacial bonding force, and nano zirconium oxide and other slurry-forming materials are added to prevent agglomeration, thus forming a highly efficient protective coating.

Benefits of technology

It significantly improves the adhesion stability and protective durability of the coating under outdoor service conditions, solves the problem of microcrack initiation and propagation, enhances the protective performance in acid rain and salt spray environments, and ensures the component uniformity and construction consistency of the sprayed material.

Abstract

The present application relates to the technical field of spraying material, in particular to a special spraying material for the surface of stainless steel tile, which comprises component A raw material and component B raw material.In the present application, the component A is compounded with bisphenol F epoxy resin and E51 epoxy resin as a film forming base material, which reduces the crosslinking density and brittleness of the epoxy curing system, relieves the interface stress generated by the difference in thermal expansion coefficient between the coating and the stainless steel substrate under temperature difference alternation, the treated hexagonal boron nitride in the filler has a lamellar structure, which further enhances the barrier property in cooperation with the flaky morphology of mica iron oxide, significantly inhibits the initiation and expansion of microcracks, thereby improving the adhesion stability and protective durability of the coating under long-term outdoor service conditions.
