| 研究金属表面处理工艺对金属/天然橡胶（NR）热硫化粘接剥离强度的影响。结果表明：对金属进行脱脂、
磷化和硅烷化处理能够有效增大金属/NR热硫化粘接剥离强度，3种处理工艺中对金属进行2次环保水溶性无铬密封剂
Gardolene D6890浸渍可增大金属/NR热硫化粘接剥离强度；合理调控金属磷化时间、Gardolene D6890质量分数及其浸
渍温度和浸渍后金属烘干温度能增大金属/NR热硫化粘接剥离强度；金属磷化时间为90 s、Gardolene D6890质量分数为
5%及其浸渍温度为55 ℃时金属/NR热硫化粘接剥离强度最大，而提高Gardolene D6890浸渍后金属烘干温度能进一步
增大金属/NR热硫化粘接剥离强度。 |
| 英文摘要: |
| The effects of surface treatment process of metal on the peeling strength of metal/natural rubber（NR） hot vulcanization bonding were studied.The results showed that degreasing，phosphating and silane treatments could effectively increase the peeling strength of metal/NR hot vulcanization bonding.Two times of impregnation with environmentally friendly water-soluble chromium-free coating Gardolene D6890 in the three kind of treatment processes could further increase the peeling strength of metal/NR hot vulcanization bonding.Moreover，the peeling strength of metal/NR hot vulcanization bonding could also be improved by reasonable control of the phosphating time of metal，the mass fraction of Gardolene D6890，the impregnation temperature and the drying temperature of the impregnated metal.It was found that when the phosphating time of metal was 90 s，the mass fraction of Gardolene D6890 was 5% and the immersion temperature was 55 ℃，the peeling strength of metal/NR hot vulcanization bonding was the largest，and increasing the drying temperature of Gardolene D6890 impregnated metal could further increase the peeling strength of metal/NR hot vulcanization bonding. |
