| 目的 寻求替代含铬绝缘涂料的环保绝缘涂料。 方法 采用水溶性磷酸盐和水性树脂自制水性涂料,在无取向硅钢表面制备绝缘涂层,研究其固化工艺,并与国内涂料进行理化指标和涂层性能(附着力、表面电阻、耐腐蚀性能、耐热性)对比。 结果 自制绝缘涂料无刺激性气味,稳定性好,使用寿命长,在固化时间 20 ~24 s、固化温度 480 ~520 ℃的条件下,可在无取向硅钢表面制得均匀、光亮的银灰色绝缘涂层。 绝缘涂层附着力为 A 级,12 h 中性盐雾试验腐蚀面积低于 5% ,在 750 ℃ 高温退火 2 h 不掉粉,表面绝缘电阻为 297 Ω/ mm2(1. 0 ~1. 2 μm)。 结论 自制水性绝缘涂料为环保型单组分涂料,与国内绝缘涂料的涂层性能相当,满足国内钢厂产品技术要求。 |

| Objective To seek environment-friendly insulating paint for replacing chromate coating. Methods A new chromatefree insulating coating on non-oriented silicon steel was prepared using self-made water-based paint composed of inorganic salt and water-soluble resin. The curing process of the insulating paint was studied, and the performance (adhesion, high temperature annealing, corrosion resistance and surface insulating resistance) of the insulating coating was analyzed in comparison with domestic coatings. Results The self-made paint had low offensive odor, good stability and long life; the insulating coating was light silver gray when the curing parameters were 20 ~24 s and 480 ~520 ℃; the adhesion force of the insulating coating was A; the corrosion area was less than 5% after 12 h salt spray; there was no coating desquamate after high-temperature annealing at 750 ℃ for 2 h; and the surface resistance was 297 Ω/ mm2(1. 0 ~ 1. 2 μm). Conclusion The self-made water-based paint was a one-component chromate-free paint, the performance of the insulating coating met the technical requirement of steel products, as good as that of domestic paints. |
