| titleOfInvention | Brightener for tin plating and tin alloy, preparation method and application thereof |
| abstract | The invention discloses a brightener for tin plating and tin alloy, its preparation method and application. Each liter contains the following components: polyethylene glycol 10-30g/L, agent A 120-200g/L, agent B 120-200g/L, 2-mercaptothiazoline 2-4g/L, 100-180g/L potassium hydroxide solution with a mass concentration of 5%, and the remaining distilled water; agent A is epoxy imidazolamide solution; agent B is A mixed solution of polyvinylpyrrolidone and sodium benzoate. The preparation method is as follows: 1) Add 200-500g of distilled water into a container; 2) Add 10-30g of polyethylene glycol, heat, stir until completely dissolved and transparent, and cool; 3) Add 120-200g of A agent while stirring; 4 ) Add 120-200 g of agent B while stirring; 5) Weigh 2-4 g of 2-mercaptothiazoline, dissolve 2-mercaptothiazoline with 100-180 g of potassium hydroxide solution with a mass concentration of 5%, and then add it to the 4) into the solution; 6) add distilled water to a constant volume of 1000ml, and stir evenly. In application, add 5-80g of brightener per liter of plating solution. The brightener of the invention is added into the plating solution, which can make the property of the plating solution stable and the performance of the plating layer is good. |
