Embodiment 1
[0051] Electroless copper plating on the surface of a plastic sheet made of acrylic-butadiene-styrene copolymer (ABS) resin-based plastic blend. Specific steps are as follows:
[0052] 1. According to the mass ratio ABS matrix resin: talcum powder: silver powder=80:20:0.01, calculate the quality of silver nitrate to be used, and then weigh the corresponding mass of ABS matrix resin, talcum powder and silver nitrate powder.
[0053] 2. Pour the weighed talcum powder into the aqueous solution of silver nitrate, stir it mechanically for 30 minutes to make it evenly mixed, filter it with suction, and then dry it in vacuum.
[0054] 3. Place the dried talcum powder coated with silver nitrate on the surface for 1 hour in the sun, so that the silver nitrate coated on the surface of the talc powder is decomposed into nano-silver powder.
[0055] 4. Blend and extrude the talcum powder coated with nano-silver powder on the surface and the weighed ABS matrix resin in a twin-screw extrud...
Embodiment 2
[0061] With the mass ratio of polypropylene (PP) matrix resin: calcium carbonate powder: copper nitrate = 80: 20: 10, the copper-plated PP blend sheet was prepared according to the operation of Example 1. And the samples were tested for the bonding force of the surface metal coating. The test results are shown in Table 1.
[0062] The reagents, raw materials, test methods and standards, and test instruments used in the specific examples of the present invention are shown in Tables 1-4 below.
[0063] Performance Testing:
[0064] The adhesion test of the metal coating on the surface of the plastic sheet, referred to as the Baige method:
[0065] Under the conditions of room temperature 23±2°C and relative humidity 50±5%, use a sharp blade (the angle of the blade is 15°~30°) to draw 10×10 small grids of 1mm×1mm on the surface of the test sample, each scribe line Deep to the bottom layer of the coating; use a brush to clean the debris in the test area; use 3M600 adhesive tape...
