技术领域
本发明涉及化学镀银领域，尤其涉及一种搪塑模具的化学镀银工艺。
背景技术
化学镀银是为了环氧树脂芯模可以导电，保证可以进行电铸。一般化学镀银分为除粗化、敏化、上镀四个步骤。但是效果差，影响后续的电镀的效果和模具的制造。

发明内容
本发明为克服以上不足，提供搪塑模具的化学镀银工艺，包括的步骤有：
除油：用洗涤剂、自配清洗液(5g/L的磷酸钠+1g/L的十二烷基硫酸钠)对环氧树脂表面进行清洗；
粗化：将环氧树脂侵泡在温度为40～60℃含5％单宁酸中5～10min时间；或用10ml/l的异丙醇溶液润洗5～10min；
敏化：将敏化液反复淋洒在粗化后的环氧树脂，然后用去离子水缓慢冲洗，使氯化亚锡充分水解；
上镀：将已配好的银氨溶液和还原液装入壶中，上镀即化学镀银，将银氨溶液和还原液按体积比为1:1的量喷射到敏化过的环氧树脂上，将在其表面形成一层银层；
所述银氨溶液：8g硝酸银溶于100ml去离子水中，滴加氨水至澄清，银离子的浓度为10g/l。
所述葡萄糖浓度为10～15g/l；
所述敏化液为20ml的HCl和20g的SnCl2。
