2results about How to "Improve deep plating ability" patented technology

The application provides a brightener, a preparation method and application thereof. The brightener has a structure as shown in formula 1, wherein R is any one of CH3-(CH2) x -, Ph-(CH2) y - or an azacyclic group, x is 2-5, and y is 0-4. The brightener is connected with a functional group having strong polarity, has good inhibition effect on copper, and has a capturing cuprous ion at the other end of the structure, accelerates copper deposition, has certain leveling performance, can form leveling effect on the surface copper high potential, forms acceleration effect on the low point position in the hole, and can effectively improve the deep plating capacity of the acid copper plating solution, and the deep plating capacity can reach 79-85%.

The invention relates to an environment-friendly cyanide-free zincate zinc plating brightener and a preparation method thereof, and relates to the technical field of metal surface treatment. The polishing solution comprises the following components in parts by mass: 10-30 parts of sulfonic modified p-chlorobenzalacetone, 10-20 parts of conjugated modified anisaldehyde, 15-40 parts of a compound auxiliary brightener, 5-15 parts of iso-tridecanol polyoxyethylene ether, 3-10 parts of polyethylene glycol, 2-8 parts of a displacement agent and 30-50 parts of ethylene glycol monobutyl ether. The preparation method comprises the following steps: adding sulfo-modified p-chlorobenzylidene acetone into ethylene glycol monobutyl ether under a water bath heating condition, uniformly stirring, sequentially adding conjugated modified anisaldehyde, iso-tridecanol polyoxyethylene ether, polyethylene glycol, a compound auxiliary brightener and a displacement agent, stirring after each component is added, and uniformly stirring to obtain a mixture; and after the addition is finished, increasing the rotating speed and continuously stirring to obtain the environment-friendly cyanide-free zincate zinc-plating brightener. The brightening agent has the effect of improving the dispersing performance of the brightening agent, and the uniformity and the brightening effect of a plating layer can be effectively improved.
