研制了一种水基印刷线路板油墨清洗剂。研究了清洗剂中的氢氧化钠、磷酸三钠、三聚磷酸钠、硅酸钠用量对油墨去除率的影响。采用超声辅助清洗工艺,探讨了清洗温度和清洗时间对不同类型印刷线路板油墨去除效果的影响。油墨清洗剂的较优组成为:氢氧化钠6%,磷酸三钠2%,三聚磷酸钠2%,硅酸钠1%,氯化钠2%,亚硝酸钠1%,表面活性剂AES1%,表面活性剂K121%,表面活性剂SAS-601%。该油墨清洗剂具有良好的清洗能力,油墨去除率高。在清洗温度80～90°C、清洗剂中活性物质量分数为17%的条件下,对普通型线路板、烘烤型线路板分别清洗5～8min、45～50min,油墨去除率均可达100%。
Developed a water-based printed circuit board ink cleaner. The effects of sodium hydroxide, trisodium phosphate, sodium tripolyphosphate and sodium silicate on the ink removal efficiency were studied. Ultrasonic-assisted cleaning process was used to investigate the effect of cleaning temperature and cleaning time on the removal of different types of printed circuit board ink. The optimum composition of the ink cleaner is as follows: sodium hydroxide 6%, trisodium phosphate 2%, sodium tripolyphosphate 2%, sodium silicate 1%, sodium chloride 2%, sodium nitrite 1%, surfactant AES1 %, Surfactant K121%, surfactant SAS-601%. The ink cleaning agent has good cleaning ability, high ink removal rate. In the cleaning temperature of 80 ~ 90 ° C, the active agent content of the cleaning agent was 17% under the conditions of the ordinary circuit boards, baking circuit boards were washed 5 ~ 8min, 45 ~ 50min, the ink removal rates are up 100%.
