摘要焦化行业炉前作业一直是高温、高污染的特殊岗位，至今仍然依赖于人工操作清除炭化室门前的余煤、炉头焦以及淌焦板上黏附的焦油、沥青等物质。炼焦过程中煤焦油、沥青沿炉门滴流到淌焦板上，并牢牢地黏附在淌焦板上，很难清除并严重危害环境及人体健康。本文中主要研究水性氟碳涂料、水性防粘污面漆对煤焦油的清除性能，其中涉及到水性氟碳涂料、水性硅基涂料在国内外的研究进展、四种不同固化温度下的涂膜性能检测以及水性氟碳涂料、水性防粘污面漆对煤焦油污染源清除性能的对比研究，实验项目包括红外、粒度、附着力、弯曲韧性、厚度、表面干燥时间以及实际干燥时间。实验结果发现，水性氟碳涂料和水性防粘污面漆都具有优异的亲水憎油性，对煤焦油这类的油性物质具有良好的拒污染性能。57604

Abstract

The operation in front of coking furnace has been a special job under high temperature and high pollution, which is still relying on manual operation to clear the coal, coke, coal tar and pitch on the surface of coke plates. The coal tar and pitch drop and stick on the surface of coke plate in the coking-pushing process, causing great difficulties to cleanness, which is harmful to the environment and human health. In this paper, a water-based fluorocarbon coating and a water-based anti-fouling paint were selected to study their adhesion towards coal tar. The FT-IR spectra and particle size analyses of the coatings, and the adhesive force, thickness, bending resistance of their dried film on the tin plates were investigated. Based on the results, the water-based fluorocarbon coating and water-based anti-fouling paint all have excellent hydrophilic and oilphobic properties, thus the coal tar is easy to remove from the tin plates after painting above coatings.

KeyWords：Fluorocarbon ; organic silicon; coating; coal tar; removal
