Problems solved by technology

[0005] 1. The cost of magnetron sputtering equipment is high, and the process control is difficult;
[0006] 2. The magnetron sputtering process is an offline process, that is, the film is processed after the film is produced, the production cycle is long, the output per unit time is low, and the production efficiency is low;
[0007] 3. The magnetron sputtering process needs to be carried out above the glass transition temperature of the film substrate. Repeated heating will cause deformation of the film, and poor planarity will affect product quality.

preparation example Construction

[0057] Figure 1 Apparatus diagram of the in-line copper coating process portion using the preparation process of the present invention. Comprising die 1 and polymer melt 5, polymer melt 5 extruded by die 1, polymer melt 5 is successively provided with nozzle 2, suction air outlet 3 and quench roller 4.

[0058] Nozzle 2 is a set of two, symmetrically set above and below the polymer melt 5. The vertical distance h between nozzle 2 and polymer melt 5 is 0.8cm and the horizontal distance d from die 1 is 1.5 cm. The nozzle 2 is in the shape of a crack, the width of the gap is 0.01mm, and the length is 0.6m. The nozzle 2 is connected to the silo where the nano copper powder is stored.

[0059] Suction port 3 is also a set of two, symmetrically set above and below the polymer melt 5. The vertical height of the suction port 3 from the polymer melt 5 is 0.8cm, and the horizontal distance from the nozzle 2 is 2 cm. Nano copper powder is compressed gas is transported to the upper and lowe...

Embodiment 1

[0061] First of all, the solid polyphenylene sulfide powder (the manufacturer is Zhejiang Xinhecheng Special Materials Co., Ltd., the grade is NHU-PPS3508P, the average weight weight is 60000 ~ 65000) is melted, and the twin screw extruder is extruded into a granular solid, and then put into the vacuum to dry, and the excess water is taken away by controlling the dry nitrogen passed in, as the final raw material for making the film.

[0062] The dried granular material is fed into a twin screw extruder for melting, metering, and feeding to the die, and the temperature of the melt extruded by the die is controlled to 285 °C. At the same time as the die is extruded, the nozzle extrudes copper powder to the surface of the melt, wherein the copper powder D50 is 40nm, the compressed air pressure is 0.5MPa, the suction air pressure is 8000Pa, and the speed of the cold roller is 50m / min, resulting in a sheet coated with copper.

[0063] Then the sheet is sent into the longitudinal stretc...

Embodiment 2

[0067] In the present embodiment, the copper powder D50 is 50nm, the compressed air pressure is 0.5MPa, the air pressure at the inlet is 8000Pa, and the speed of the quenching roller is 50m / min.

[0068]In addition, the ppS film is made using the same steps as In Example 1.

[0069] For the PPS film obtained by the above method, the evaluation results are shown in Table 1, and the film warpage performance is excellent, and the thickness of the copper layer as a buffer layer reaches the nanometer level and the uniformity is excellent.

Abstract

The invention discloses a method for preparing a copper-coated polymer film and its products. The method for preparing the copper-coated polymer film includes melting and filtering polymer raw materials, extruding from a die, and attaching nano-copper powder to the The outer surface of the polymer melt extruded through the die is cast to obtain a polymer sheet coated with a nano-copper layer, and then biaxially stretched and heat-set to obtain a copper-coated polymer film; the nozzle is at least One. The preparation method disclosed in the invention combines the film manufacturing process and the coating process into one, which greatly reduces the production cycle and improves production efficiency; the prepared copper-plated polymer film has low warpage, better planarity, and high yield greatly increase.

Description

Technical field [0001] The present invention relates to the field of metallization of the surface of the film, in particular to a copper-plated polymer film preparation method and product thereof. Background [0002] At present, the negative collector material of energy storage equipment is mostly copper foil, but the density of copper is high and the weight is large, and the lightweight replacement of copper can reduce the weight of energy storage equipment, improve its energy density, and achieve progress in endurance. Replacing copper foil with thin film copper plating as a negative collector material for energy storage equipment is currently a solution. [0003] Polyphenylene sulfide (PPS) is a polymer containing a repeating structural unit of p-phenylene sulfide in the molecule, which is a new type of functional engineering plastic, with excellent thermal stability, electrical insulation, corrosion resistance, flame retardancy and good mechanical properties, and is widely u...
