AI Technical Summary

Technical Problem

Traditional offshore wind turbine tower coating processes suffer from reduced corrosion resistance, complex construction, and high costs, making it difficult to meet the requirements for long service life and low maintenance.

Method used

A nanoparticle-modified epoxy heavy-duty anti-corrosion coating was prepared by compounding a self-made nano-modified resin with epoxy resin, adding pigments, fillers and amine curing agents, and improving adhesion and density through phosphating reaction.

Benefits of technology

It improves the coating's adhesion, salt spray resistance, salt water resistance, and damp heat resistance, extends its service life, and reduces construction costs.

Abstract

本申请公开了一种纳米粒子改性环氧重防腐蚀涂料。采用自制的纳米改性树脂与环氧树脂复配作为主要成膜树脂，添加颜填料、助剂制备得到A组分，胺类固化剂为B组分，A组分活环氧的物质的量与B组分活泼氢的物质的量比为1:(0.7～1.3)。本发明制备的涂料因含有P‑OH结构，使该类涂层与金属基材通过磷化反应产生化学键的结合，大幅提升涂层的附着力，纳米离子的引入及提升了涂层的致密性，因此这种纳米粒子改性的环氧涂料具有优异的附着力、耐盐雾、耐盐水、耐湿热等性能。
