摘要
采用拉开法测定了PPS/FEP共混改性防腐涂层的结合强度 ,研究了共混组分PPS对复合防腐涂层结合强度的影响 .结果表明 ,PPS明显改善了单纯氟树脂涂层对金属的不粘性 ,PPS/FEP共混单层涂层 (中间层 1)的结合强度可达 8 31MPa;对于PPS/FEP五层复合涂层 ,涂 /基结合强度可达 11 8MPa .电子探针分析结果显示 ,五层体系中各组分沿横截面呈梯度分布 ,有效加强了层间结合 .
The bongding strength of blended PPS/FEP anti-corrosion coatings was determined by pull-off test.The effects of the blending component PPS on the bongding strength were studied.The results indicated that the poor adhesion of fluororesin coatings to metallic substrates was changed obviously by PPS,the bonding strength of single coating of blended PPS/FEP(interlayer 1)was 8.31MPa;for five-layer of PPS/FEP composite coatings,the bonding strength reached up to11.8 MPa.The EPMA(electron probe microanalysis)results showed that the distribution of main components was graded in the five-layer system,which enhanced the interfacial bonding between layers.
