Problems solved by technology

In the prior art, organometallic chelates are usually used as non-conductive organometallic photosensitive compounds, which are expensive, added in a large amount (greater than 1wt% matrix resin), and highly toxic, making the use of organometallic chelates as photosensitive compounds. Additive polymers are expensive, highly toxic and complicated to process

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...

Abstract

The invention provides an inorganic filler plastic blending material, a preparation method thereof and a surface metalized plastic part which takes the blending material as raw material and is manufactured according to a laser direct forming process, wherein, at least one kind of transition metal ions and nanoscale metal particles is coated on the surface of the inorganic filler plastic blending material. The inorganic filler plastic blending material overcomes the disadvantages that the organic metal chelate used as photosensitizer additive has high plastic toxity and high cost, and the processing technique is complex; in addition, the adhesive force of the coated metal of the surface metalized plastic piece prepared by the plastic blending material and the basal body of the plastic pieceis good.

Description

technical field [0001] The invention relates to a plastic blend, in particular to a plastic blend which can be processed by laser direct molding, and a preparation method of the plastic blend. Background technique [0002] LDS-MID is a technology that uses laser direct structuring (Laser Direct Structuring-LDS) to manufacture plastic parts with partially or fully metallized surfaces. This technology is to mix a small amount of non-conductive organic metal photosensitive compound into the plastic, and use laser to project a predetermined area on the surface of the plastic part, so that the photosensitive compound in this area is reduced to metal particles under the action of light / thermal coupling. At the same time, the plastic part of this area is etched away by laser, so that the reduced metal particles are exposed on the surface of the plastic part, thereby forming a laser-etched area of ​​a certain shape on the surface of the plastic part. Then use electroless plating to...
