Problems solved by technology

[0004] Subsequent researches on chromium-free formulations have suggested solutions of potassium permanganate and sulfuric acid, and hydrogen peroxide formulations are also available, but due to poor roughening effects, they have not been widely used. Compared with the roughening of nylon materials and alloys Liquid, which has never appeared in the prior art

Embodiment 1

[0015] A roughening solution for nylon material, which is composed of the following components by weight percentage: 16% sulfuric acid, 1% hydrochloric acid, 5% citric acid, 10% glacial acetic acid, 5% formic acid and 63% water.

[0016] In the process of surface treatment of nylon used in car handles, first select a cleaning agent to clean the surface of the nylon, remove the injection molding oil and wax on the surface of the nylon, and then remove the residual cleaning agent by washing with water, and then use the immersion method to roughen the nylon material. Roughen the surface of the nylon with liquid, ultrasonically roughen at room temperature for 2 minutes, the by-products produced during the roughening process are washed with water to remove the residual roughening solution, and then activated by palladium ions, then degummed, chemical nickel, and subsequently electroplated copper, Nickel, chrome, finish nylon plating.

Abstract

The invention discloses a nylon material roughing solution and a roughing method using same. The nylon material roughing solution comprises, by weight, 1-16% of sulfuric acid, 1-16% of hydrochloric acid, 5-15% of citric acid, 4-20% of glacial acetic acid, 1-20% of formic acid and 50-70% of water. The roughing method comprises the following steps of 1, cleaning a nylon semifinished product to remove oil and wax and carrying out secondary washing by water, 2, immersing the nylon semifinished product into the nylon material roughing solution and carrying out ultrasonic roughing at a normal temperature for 2-6min, and 3, carrying out water washing, carrying out palladium ion activation, carrying out dispergation, carrying out electroless nickel plating, and carrying out acid copper, nickel and chromium electroplating so that nylon material electroplating is finished. Through the roughing method, a nylon material has good surface roughing effects. The nylon material roughing solution reduces the damage produced by the roughing process on the environment and operators.

Description

technical field [0001] The invention relates to a roughening solution and a roughening method for nylon materials, in particular to an acidic roughening solution and a roughening method without chromium anhydride. Background technique [0002] The roughening solution is a chemical solution used in plastic electroplating to roughen the plastic surface. The plastic obtains a microporous structure and a hydrophilic surface through the roughening solution, and then deposits palladium ions for electroless plating to realize plastic metallization. The quality of roughening directly affects the bonding force, brightness and integrity of the coating. Coarsening is the prerequisite for realizing plastic metallization and a necessary condition for obtaining good bonding force. [0003] In the prior art, the roughening solution used for ABS plastics and PC materials is a mixed solution containing chromic anhydride, such as a mixed solution of chromic anhydride and sulfuric acid, or a m...
