Purpose

In this paper, two promising corrosion inhibitors based on natural and eco-friendly materials such as peanut fatty acids (PFA) were prepared and challenged with a common efficient commercial inhibitor. Two amino derivatives based on aliphatic and aromatic compounds such as 2-amino-2-methyl-1-propanol (AMP) and 2-amino-2-phenyl-1-propanol (APP), respectively, were used and reacted with PFA under controlled conditions to produce the corrosion inhibitors. The prepared inhibitors, namely, PFA-AMP (inhІ) and PFA-APP (inhІІ), were confirmed and characterized by Fourier transfer infrared spectroscopy, acid value determination and viscosity measurements.

Design/methodology/approach

First, different coating formulations free from any inhibitors were prepared and irradiated under different doses of electron beam source to select the best dose. Several concentrations of synthesized anticorrosion materials were then added to coating formulations to estimate them as anticorrosion materials for mild steel panels. Then, all formulations were coated and polymerized at a dose of 10 kGy. The corrosion tests, weight loss and water uptake were studied for all films after immersion in 3.5% sodium chloride. Moreover, the chemical and physico-mechanical properties were determined for all films.

Findings

The results exhibited that the different concentrations of two inhibitors did not show any significant change on the different properties of all films, and the best concentration, which gives the better protection for steel panels, was to be 1.0 g for two inhibitors.

Originality/value

It was found that the protection efficiency of the inhІ is better and higher than that of the inhІІ and also of the commercial inhibitor with the following order: inhІ > commercial inhibitor > inhІІ.

电子束固化钢涂料中基于脂肪族和芳香族化合物的环保型缓蚀剂的制备与比较研究

目的

在本文中，制备了两种基于天然和生态友好材料（如花生脂肪酸（PFA））的有前途的腐蚀抑制剂，并用一种​​常见的有效商业抑制剂进行了挑战。使用了两种基于脂肪族和芳香族化合物的氨基衍生物，例如2-氨基-2-甲基-1-丙醇（AMP）和2-氨基-2-苯基-1-丙醇（APP），并在PFA下与PFA反应。在控制条件下生产缓蚀剂。通过傅立叶转移红外光谱法，酸值测定和粘度测量对所制备的抑制剂，即PFA-AMP（inhІ）和PFA-APP（inhІІ）进行了确认和表征。

设计/方法/方法

首先，制备不含任何抑制剂的不同涂料制剂，并在不同剂量的电子束源下照射以选择最佳剂量。然后将几种浓度的合成防腐材料添加到涂料配方中，以评估它们作为低碳钢板的防腐材料。然后，以10kGy的剂量涂覆和聚合所有制剂。在浸入3.5％氯化钠中后，对所有薄膜进行了腐蚀测试，重量损失和吸水率的研究。此外，测定了所有膜的化学和物理机械性能。

发现

结果表明，两种抑制剂的不同浓度对所有薄膜的不同性能均未显示任何显着变化，而对钢板具有更好保护效果的最佳浓度为两种抑制剂为1.0 g。

创意/价值

已经发现，inh +的保护效率比inh +以及商业抑制剂的保护效率更好和更高，其顺序如下：inh +＞商业抑制剂＞ inh +。
