AI Technical Summary

Problems solved by technology

[0009] (1) On soft materials, the adhesion is poor and it is easy to resist bending
[0010] (2) After electroplating on soft materials, the electroplating surface is easy to crack
[0011] (3) When the softness reaches the Shore65A index, the electroplating effect cannot be achieved

Embodiment 1

[0032] A kind of vacuum electroplating primer, according to weight percentage, its formula is:

[0033]

[0034] Initiator is 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO), 2-hydroxyl-2-methyl-1-phenyl-1-acetone, referred to as HMPF (Ciba Corporation Trademark is the product of DAROCUR1173), 1-hydroxy-cyclohexyl-phenyl ketone (the product of Ciba Ciba Company's trademark is IRGACURE184), benzophenone (BP).

[0035] Solvents are toluene (TOLUENE), cyclohexanone (CYC), methyl isobutyl ketone (MIBK), ethyl acetate (EAC)

[0036] The auxiliary agent is a leveling agent, and the brand name BYK306 is selected from Germany BYK.

[0037] Table 1 Test results in weight percent (wt%)

[0038]

Embodiment 2

[0040] A preparation method for vacuum electroplating primer, comprising the following steps:

[0041] Step 1: According to the formula in Table 1, add the resin and monomer into the dispersing tank according to the following formula, start stirring at a low speed of 500-800r / min, and stir for 30 minutes;

[0042] Step 2: After the materials are mixed evenly, turn on 1200-1500r / min high-speed dispersion, and stop stirring after 1 hour;

[0043] Step 3: Add photoinitiator, additives, and solvent in proportion, and stop after high-speed dispersion for 1 hour to obtain the target product.

Embodiment 3

Abstract

The invention discloses a vacuum electroplating primer. The prescription of the vacuum electroplating primer comprises the following components in percentage by weight: 10-30% of urethane acrylate, 5-10% of butyl acrylate, 5-10% of hydroxyethyl methacrylate, 5-20% of modified epoxy acrylate, 0-10% of vinyl chloride-acetate copolymer resin, 1-6% of initiator, 20-60% of solvent, and 0.1-0.5% of auxiliaries. The invention further discloses a preparation method and an application for the vacuum electroplating primer. The vacuum electroplating primer disclosed by the invention has an adhesive force on a flexible material and can bend without cracks, so that the problem of electroplating on the flexible material is solved.

Description

technical field [0001] The invention relates to a vacuum electroplating primer and its preparation method and application, in particular to a vacuum electroplating primer for supersoft materials and its preparation method and application. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent Corrosion, improve wear resistance, electrical conductivity, reflective properties and improve appearance. [0003] 1) Water electroplating, also known as wet electroplating, as the name implies, is related to water and aqueous solutions. The principle of electrochemical reaction is a chemical process. Pollution is high due to extensive use of water / aqueous solutions. [0004] 2) Ultraviolet (UV) coating, using UV coating, in a vacuum ...
