Embodiment 1

[0056] A plastic electroplating process for automotive interior panels, comprising the following method steps:

[0057] The first step: stress relief treatment of plastic plaque

[0058] First check whether there are cracks or flaws on the surface of the injection-molded plastic veneer. After the inspection, place the plastic veneer in a ventilated place for 12-24 hours. The internal stress of the decorative plate, when the plastic decorative plate meets the storage time requirement, put the plastic decorative plate into the soaking tank, and pour glacial acetic acid with a solubility of 17.5mol / L into the soaking tank, and completely immerse the plastic decorative plate and soak it After 20 minutes, the temperature of glacial acetic acid should be basically the same as the ambient temperature. If the ambient temperature is too low and the temperature of the plastic veneer is too low, put the plastic veneer in an oven and heat it to an appropriate temperature before taking it ...

Embodiment 2

[0077] A plastic electroplating process for automotive interior panels, characterized in that it comprises the following method steps:

[0078] The first step: stress relief treatment of plastic plaque

[0079] First check whether there are cracks or flaws on the surface of the injection-molded plastic veneer. After the inspection, place the plastic veneer in a ventilated place for 24-48 hours. The internal stress of the decorative plate, when the plastic decorative plate meets the storage time requirement, put the plastic decorative plate into the soaking tank, and pour glacial acetic acid with a solubility of 17.5mol / L into the soaking tank, and completely immerse the plastic decorative plate and soak it After 20 minutes, the temperature of glacial acetic acid should be basically the same as the ambient temperature. If the ambient temperature is too low and the temperature of the plastic veneer is too low, put the plastic veneer in an oven and heat it to an appropriate tempe...

Abstract

The invention discloses a plastic electroplating process of vehicle interior panels. Firstly, cracks or flaws are examined on the surfaces of plastic panels or not after injection molding; after examination, the plastic panels are placed in a ventilation place for standing by 24-48 hours; and the placing environment temperature is maintained between 10-30 DEG C, so that the internal stress of partof the plastic panels is reduced. In the plastic electroplating process of the vehicle interior panels, through higher roughening capacity on electroplating-stage ABS plastic, the main effect of chromic acid is to oxidize ABS or butadiene in PC-contained ABS to form anchoring points, so that more hydrophilic polar groups are generated on the plastic surfaces; and due to existence of the groups, the hydrophilia of the plastic surfaces is greatly improved, the chemical bonding is facilitated, the plating layer bonding force is improved, subsequent electroplating metal elements are preferably attached on the surfaces of the plastic panels, the metal fall caused by weakening of the plating layer bonding force after long-time use is prevented, and the advantage of better wear resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of plastic electroplating technology, in particular to a plastic electroplating technology for automotive interior panels. 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 metal oxidation. Improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance the appearance, etc. The outer layer of many coins is also electroplated. [0003] With the continuous development of plastic products, it has been widely used in various fields. In the automotive industry, plastic products are mainly used in front and rear bumpers and interior materials of cars, but because the gloss of plastic is not as good as metal, In order to create...
