纳米二氧化钛浓缩浆对硼酚醛环氧涂料性能的影响
Effect of TiO2 Nano-concentrates on the Properties of Boron Phenolic-epoxy Coatings
摘要
Abstract
Objective To improve the corrosion resistance, surface contact angle, bonding strength and abrasion resistance of boron phenolic-epoxy coatings. Methods In this paper, boron phenolic-epoxy coatings were modified by TiO2 nano-concentrates, and composite nano-coatings with resistance against high temperature and corrosion were prepared in the study. The corrosion re-sistance of nano-coatings was evaluated by immersion test in high-sulfur crude oil. The SEM morphology observation and measure-ment of surface contact angle, bonding strength and abrasion resistance were used to investigate the effect of TiO2 nano-concentrates on the properties of boron phenolic-epoxy coatings. Results From the SEM observation, no defects were found on the surface of bo-ron phenolic-epoxy nano-coatings after exposure to 100 ℃ high-sulfur crude oil. 2% TiO2 nano-concentrates improved the perme-ation resistance and abrasion resistance of nano-coatings. The bonding strength of composite nano-coating only decreased from 7. 7 MPa to 6. 9 MPa after the corrosion test, and the surface contact angle of nano-coating was 4°~7° higher than that of coating with-out nano-particles during the 720 h corrosion test. Conclusion The morphological structure, bonding strength and abrasion resis-tance of boron phenolic-epoxy nano-coatings were not damaged by 100 ℃ high-sulfur crude oil. 2% TiO2 nano-concentrates in-creased the permeation resistance and surface contact angle of the composite nano-coating.关键词
