一种橡胶快速化学镀铜的方法
摘要：
本发明涉及一种橡胶快速化学镀铜的方法，属于化学镀膜工艺技术领域。本发明包括步骤：对橡胶表面进行打磨，碱洗除油，粗化，酸洗，敏化，活化；配置化学镀液；其组成及浓度为：主盐五水硫酸铜20～30g/L；络合剂EDTA 20～40g/L，酒石酸钾钠5～15 g/L，选上述络合剂中的一种或多种；还原剂甲醛7～9ml/L；稳定剂甲醇5～8ml/L；碱性调节剂氢氧化钠；余量为水。化学镀铜；温度50～80℃，pH 12～14，施镀时间2～12分钟。水洗，并在40～90℃下烘干。本发明用于各类橡胶的镀铜，镀后镀层具有厚度均匀，结合力强的特点。
摘要（英）：

The invention relates to a method of rapid electroless copper plating of rubber, and belongs to the technical field of the electroless plating technology. The method comprises the steps that polishing, alkali cleaning and oil removal, roughening, acid cleaning, sensitization and activation are conducted on the surface of rubber; an electroless plating solution is prepared; electroless copper plating is conducted, wherein the temperature ranges from 50 DEG C to 80 DEG C, the pH value ranges from 12 to 14, and the plating application time ranges from 2 minutes to 12 minutes; water cleaning is conducted, and drying is conducted at the temperature ranging from 40 DEG C to 90 DEG C. According to the composition and the concentration of the electroless plating solution, the electroless plating solution comprises 20g/L-30g/L of copper sulfate pentahydrate, 20g/L-40g/L of EDTA, 5g/L-15g/L of potassium sodium tartrate, 7ml/L-9ml/L of formaldehyde, 5ml/L-8ml/L of ethyl alcohol, sodium hydroxideand the balance water, wherein copper sulfate pentahydrate serves as main salt, EDTA and/or potassium sodium tartrate is selected as a complexing agent, formaldehyde serves as a reducing agent, methylalcohol serves as a stabilizing agent, and sodium hydroxide serves as an alkaline conditioning agent. The method of rapid electroless copper plating of rubber is used for copper plating of various kinds of rubber, and a plated coating formed after plating has the advantages of being uniform in thickness and high in binding force.
