Embodiment Construction
[0017] Such as figure 1 As shown, the production process of the iron-based copper-clad laminate provided in this embodiment includes: descaling treatment on the surface of the iron substrate, roughening treatment on the surface of the iron substrate, phosphating treatment on the surface of the iron substrate, activation treatment of the phosphating film, small molecule substrate Glue preparation and coating, prepreg preparation, lamination and pressing. The details are as follows:
[0018] 1. Descaling treatment on the surface of the iron substrate: Clean the surface of the galvanized cold-rolled steel sheet with an organic solvent to remove the oil on the surface.
[0019] 2. Surface roughening of iron substrate:
[0020] ①Paste a protective film on one side of the iron substrate first, and then carry out surface treatment on the other side as the bonding surface.
[0021] ②Use an 80-mesh non-woven roller grinder to mechanically polish the bonding surface of the iron subst...

The invention discloses an ion-based laminated sheet with a copper foil coating, and a preparation method thereof. The ion-based laminated sheet with a copper foil coating comprises an iron substrate, a micro-porous phosphate film, a micro-molecular primer layer, a prepreg and a copper foil. The micro-porous phosphate film is arranged on the upper surface of the iron substrate. The micro-molecular primer layer is positioned on the micro-porous phosphate film. The prepreg is arranged on the micro-molecular primer layer. The preparation method comprises steps that: chemical treatment is carried out upon the surface of the iron substrate, such that the micro-porous phosphate film with micro-pores is formed on the surface of the iron substrate; the micro-molecular primer layer is arranged on the micro-porous phosphate film; the micro-molecular primer well permeates into the micro-pores of the phosphate film; and the micro-porous phosphate film is laminated and spliced with the prepreg through the micro-molecular primer layer. The iron-based laminated sheet with the copper foil coating has a more stable structure. With the method provided by the invention, poor yield caused by lamination is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of copper-clad laminates, in particular to an iron-based copper-clad laminate and a preparation method thereof. Background technique [0002] With the development of functionalization of electronic instruments and instruments, correspondingly, the basic skeleton of electronic products - copper clad laminates have also put forward functional requirements. Typical representatives of metal-based copper-clad laminates are aluminum-based copper-clad laminates and iron-based copper-clad laminates. Aluminum-based copper-clad laminates have been marketed and are widely used in high-power module circuits and high-power lighting products because of their good thermal conductivity; Iron-based CCL has the special function of magnetic conductivity and is used in special fields, such as high-performance disk drives, brushless DC motors, video recorders and other electronic and electrical products with magnetic requirement...
