Transfer printing forming method for metallized circuit of plastic part

Abstract

The invention discloses a transfer printing forming method for a metallized circuit of a plastic part. The transfer printing forming method comprises the following steps: step 1, a carrier is selected; 2, low-temperature curing conductive silver oil is coated in a transfer printing steel plate groove, a pattern is directly transferred to the carrier through transfer printing, and transfer printing is carried out according to the pattern shape to form a three-dimensional circuit; and 3, the transferred product is subjected to low-temperature baking, the baking temperature ranges from 60 DEG C to 100 DEG C, and the baking time ranges from 30 min to 60 min. The transfer printing forming method for the metallized circuit of the plastic part has no special requirements on a plastic carrier material, a PPS process can coat conductive silver oil on a plastic carrier through a transfer printing (gravure printing) technology, a 3D circuit can be realized through a transfer printing splicing process, a conductive circuit can be quickly formed, the PPS process can be suitable for material carriers such as PPA, PC, ABS, PC + ABS, PPA, PET, PI and glass. The PPS process can directly transfer required circuit patterns on the surface and the inner side of the carrier, and a circuit is formed through low-temperature baking.

Description

technical field [0001] The invention relates to the technical field of circuit transfer printing, in particular to a transfer printing forming method for metalized circuits of plastic parts. Background technique [0002] Extruded plastic surface thermal transfer metal film decoration products apply the thermal transfer film printing process to the plastic extrusion product process, using dot printing (resolution 300dpi) to paint metal, stainless steel wire drawing, wood grain, marble, etc. The pattern is printed on the surface of PET and polyester film, and then transferred to the surface of the plastic extruded product by thermal transfer printing. After the product is formed, the transfer layer and the plastic surface are integrated with high metal texture (or wood grain, marble grain, etc.) Decorative products, this process can decorate the surface, side and end surface of extruded products, can decorate arc, 3600, special-shaped surface, serrated surface, and seamless co...

Problems solved by technology

[0006] The traditional LDS (Laser Direct Structuring) process requires special plastic materials and special laser equipment. The laser laser process is long, requires copper plating, nickel plating and then gold plating, and the cost of electroless plating is extremely high, and modified PC, PA, PC are used +The toughness of ABS material is not as good as that of ordinary materials, and the surface of the product will change color after chemical plating, and it is not easy to make a high-gloss surface. Therefore, we have improved this and proposed a transfer molding method for metallized lines of plastic parts.
