Embodiment 1

[0053] Step 1, wash the surface of the steel plate with deionized water to keep the surface of the steel plate in a wet state; then polish the steel plate with sandpaper; rinse the surface of the steel plate with deionized water after polishing, and polish and clean the surface of the steel plate with cotton cloth; rinse And the polishing and cleaning process is repeated several times until the surface of the steel plate is clean and free of dirt;

[0054] Step 2, use a hot air source to heat the surface-treated steel plate to keep the surface of the steel plate at a constant coating temperature of 90°C, and then apply the release material (hardened fatty acid) to the steel plate by rolling film-making method, so that A layer of release film is formed on the surface of the steel plate;

[0055] Covering and rolling film-making method is specifically:

[0056] 1) Soak the adsorption roller in the release material;

[0057] 2) After the adsorption roller reaches saturation, pl...

Abstract

The invention discloses a method for manufacturing a release steel plate for a copper-clad plate. A hot air source is adopted for heating a steel plate subjected to surface treatment, and the surface of the steel plate is kept at constant coating temperature; then a clad-pressing and rolling film manufacturing method or clad-pressing and horizontal coating film manufacturing method is adopted for coating the steel plate with a release material, and a release film is formed on the surface of the steel plate and then is curved; and then polishing cotton is used for polishing and leveling the surface of the film, and the release steel plate is obtained. The clad-pressing and rolling film manufacturing method or clad-pressing and horizontal coating film manufacturing method is adopted for coating the surface of the steel plate with release liquid, the film is formed, and the release steel plate is obtained after curing, so that the release material and the steel plate are combined, and the problems that a laid release film is prone to slide, wrinkle and be damaged, a high-temperature film melting phenomenon is prone to happen, and a release material in an aluminum-foil-based release film is prone to migrate are solved. The semi-permanent release film resisting high temperature and abrasion is formed on the surface of the steel plate, it is guaranteed that the single-face copper-clad plate or insulation plate can be smoothly and fast separated from the steel plate after hot press molding, the appearance is qualified, and full-automatic production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of copper-clad laminates, and in particular relates to a method for manufacturing a release steel plate for copper-clad laminates. Background technique [0002] Copper-clad laminate is a plate-shaped material that is made of reinforced material impregnated with resin adhesive to make a prepreg, and one or both sides are covered with copper foil and hot-pressed. It is widely used in electronic circuits; among them, one side is covered with copper foil. It is called a single-sided board, and the one that is not covered with copper foil on both sides is called an insulating board. During the hot-pressing process of a single-sided board and an insulating board, the insulating surface needs to be in contact with the mirror steel plate, so it is necessary to cover the insulating surface with a release film to prevent insulation. The mirror surface is adhered to the mirror steel plate, and the release film is remov...
