On the morning of May 19, 2024, Shandong Chemical Industry Intelligence and Information Association organized an expert meeting to evaluate the scientific and technological achievements of the project “Water Curing Super Strong Coating Material and Its Application in Marine Engineering Equipment Facilities”, which was jointly completed by Shandong Furi Xuanwei New Material Technology Co.

The evaluation committee with academician as the evaluation director evaluated the scientific and technological achievements of the project.

The project is based on the harsh marine construction environment, from the environmental protection, long-lasting and sustainable development goals, the research and development of the substrate surface treatment requirements of low, high-performance, long-lasting anticorrosive coating materials and supporting coating technology, can be widely used in marine corrosion of the environment of the steel structure and the protection of concrete. The project has realized industrialized production, and the products have been applied in large-scale marine projects at home and abroad, with excellent application effect and remarkable economic and social benefits. The project has carried out the following innovations:

1, the first reaction to get the double epoxy monomer containing double bonds, and then copolymerized with acrylic monomers to get the multi-epoxy-based macromolecular prepolymer, and then crosslinked with polyamine curing agent to form the epoxy resin base material. Innovative realization of the crosslinking density adjustable, dense film, anti-corrosion properties.

2, the phenolic epoxy resin and calcium alumina hybridization, the preparation of organic crosslinking - inorganic gel film-forming materials, the material reacts with water to form nanocrystals, overcoming the adverse effects of the underwater environment on the resin curing, accelerating the curing speed of the resin, and enhance the strength of the coating.

3. Using silane coupling agent to graft nanoparticles onto the surface of graphene oxide, nano-modified graphene oxide was prepared, which enhances wetting dispersion, reduces secondary agglomeration, and significantly improves the anticorrosive performance of the coating material.

The Evaluation Committee listened to the report of the project team and reviewed the relevant information of the project. After questioning and discussion, it was unanimously agreed that the overall technology of the project has reached the international advanced level.
