Embodiment 1

[0046] Preparation of champagne gold electroplated silver coating suitable for PC / ABS+GF materials, water-resistant, humidity-resistant, heat-resistant and salt-spray resistant

[0047] Coating Sample Preparation

[0048] (1) Mix 3-(2,3-glycidoxy)propyltrimethoxysilane and vacuum aluminized pigment by weight according to the raw materials and proportions shown in Table 4, stir fully, and let stand for more than 2 hours;

[0049] (2) Add in order by weight: cellulose acetate modified acrylic resin, pre-dissolved and diluted thermoplastic acrylic resin, pre-dissolved and diluted ternary vinyl chloride resin, and silicone leveling agent. Use a high-speed disperser to disperse at high speed for 30 minutes;

[0050] (3) Slowly add the mixture of step 1 to the mixture of step 2 under stirring, and wash the container for the mixture of step (1) with part of the organic mixed solvent in the formula to ensure that all materials are added to the mixture of step 2 according to the formul...

Embodiment 2

[0058] The paint sample preparation process, test sample preparation conditions, performance requirements and test methods of Example 2 are the same as those of Example 1. See Table 4 for specific raw material ratios, and Table 6 for performance testing results

Abstract

The invention provides an electrosilvering coating which has excellent long-acting adhesion on a PC / ABS+GF material and has good water resistance, dampness and heat resistance and salt spray resistance, solves the problems that common electrosilvering coatings have instable adhesion on the PC / ABS+GF material and have poor water resistance, dampness and heat resistance and salt spray resistance, solves the bottleneck problem that common electrosilvering coatings only focus on appearance texture and cannot reach higher physical performance and provides an effective solution scheme for metalizedappearance of a television plastic surface frame. The electrosilvering coating is applied to ABS, PC, PC / ABS, ABS+GF and PC+GF materials as well and can be correspondingly extended to air conditioners, mobile phones, automotive interiors and exteriors and other application fields.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to an electroplating silver paint with high metal texture, excellent long-term adhesion, heat and humidity resistance and salt spray resistance, which is suitable for surface coating of PC / ABS+GF materials. Background technique [0002] As consumers have higher and higher requirements for the appearance of home appliances, TV frame decoration is also developing in the direction of high metal texture. The surface metallization of plastic materials is generally achieved by three methods: electroless plating, vacuum plating, or spraying high metal texture coatings. Electroless plating and vacuum plating are difficult to batch construction because of high cost, low pass rate, difficulty in repairing, and large surface frame size. Spraying high metal texture paint is a more ideal choice in terms of economy, construction and reworkability. Electroplated silver paint is just a ...
