摘要/Abstract

摘要：

针对氟烯烃与烷基乙烯基醚或酯的共聚物(FEVE)氟碳涂料附着力差的问题, 采用氢化松香醇对其体系进行改性, 探讨了氢化松香醇反应特性及其含量对改性FEVE氟碳涂料体系硬度、附着力及耐化学腐蚀性的影响规律。研究结果表明：氢化松香醇与FEVE氟碳涂料固化剂六亚甲基二异氰酸酯(HDI)反应的最优质量比为100∶24；氢化松香醇的加入有利于提高改性FEVE氟碳涂料涂膜的硬度及附着力, 对涂膜的耐酸性具有消极影响, 对耐碱性及耐盐水性有一定消极影响。当氢化松香醇质量分数为0.75%时, 涂膜硬度及附着力达最大值, 分别为5H和12.483 MPa, 耐碱性10 d无异常, 耐3.5%盐水10 d无异常。

关键词: 氢化松香醇, 氟碳涂料, 附着力, 耐腐蚀性

Abstract:

Addressing the issue of poor adhesion of fluoroethylene vinyl ether polymer(FEVE) fluorocarbon coatings, the hydroabietyl alcohol was adopted to modify this system. The influence of the mass fraction of hydroabietyl alcohol on the hardness, adhesion and chemical corrosion resistance of the modified FEVE fluorocarbon resin system was investigated. The results showed that the optimal mass ratio of hydroabietyl alcohol to FEVE fluorocarbon coating curing agent hexamethylene diisocyanate(HDI) was 100:24. The addition of hydroabietyl alcohol was beneficial to improve the hardness and adhesion of the modified FEVE fluorocarbon coating film, while it had a negative impact on the acid resistance, alkali resistance and salt water resistance of the paint film. When the mass content of hydroabietyl alcohol was 0.75%, the hardness and adhesion of the coating film increased to the maximum values of 5H and 12.483 MPa, respectively. The alkali resistance was normal for 10 days, and the 3.5% salt water resistance was also normal for 10 days.

Key words: hydroabietyl alcohol, fluorocarbon coatings, adhesion, corrosion resistance
