Embodiment 1

[0059] Such as figure 2 , 3 As shown, a method for producing an insulating panel in this embodiment includes the following steps:

[0060] Glue mixing: Mix and stir the epoxy resin and ingredients evenly to form glue;

[0061] Gluing: Prepare the glass fiber cloth, soak the glass fiber cloth with glue to form a semi-cured adhesive sheet;

[0062] Ingredients: According to the actual needs, various adhesive sheets are combined and stacked. In this embodiment, three FR-4 adhesive sheets 2 (glass fiber cloth adhesive sheets) of the same specification are used for lamination;

[0063] Stacking: set a mirror steel plate 1 on the top and bottom of the laminated adhesive sheet, set a non-stick layer 3 on the lower surface of the mirror steel plate 1 at the top that is in contact with the adhesive sheet 2, and set a non-stick layer 3 on the mirror surface at the bottom The upper surface of the steel plate 1 in contact with the bonding sheet 2 is provided with a non-stick layer 3, ...

Embodiment 2

[0070] Such as figure 2 , Figure 4 As shown, the technical process of this embodiment is consistent with that of Embodiment 1, except that three mirror-finished steel plates 1 are used in the stacking step, wherein the bonding sheet 2 is divided into an upper bonding sheet and a lower bonding sheet, The upper and lower bonding sheets are each laminated with three FR-4 bonding sheets 2 (fiberglass cloth bonding sheets) of the same specification, and a mirror steel plate 1 is set between the upper and lower bonding sheets. All surfaces of the steel plate 1 are provided with a non-stick layer; in addition, a mirror steel plate 1 is set on the top of the upper bonding sheet, and a non-stick layer 3 is provided on the lower surface of the mirror steel plate 1 that is in contact with the bonding sheet 2; A mirror steel plate 1 is arranged at the bottom of the sheet, and a non-stick layer 3 is arranged on the upper surface of the mirror steel plate 1 which is in contact with the b...

Embodiment 3

[0073] Such as figure 2 , Figure 5 As shown, the process flow of this embodiment is consistent with that of Embodiment 1, the difference is that non-stick layers 3 are provided on all surfaces of the two mirror-finished steel plates 1 adopted in the stacking step. The non-stick layer 3 of this embodiment is a fluorocarbon coating layer coated on the surface of the mirror steel plate 1 by means of electrostatic spraying. The coating has a single-layer structure with a thickness of 200 μm.

Abstract

The invention discloses a method for producing an insulating panel. The method comprises the steps of matching materials: enabling required bonding sheets and / or laminates to be matched and superimposed; overlapping: enabling the matched and superimposed bonding sheets and / or laminates to cover mirror steel plates, wherein non-stick layers are at least arranged on surfaces, in connection with the bonding sheets and / or laminates, of the mirror steel plates; laminating: feeding an overlapped plate material to a laminating machine for lamination. According to the method, the adopted mirror steel plates are provided with the non-stick layers, and the non-stick layers have the characteristics of being non-stick to the bonding sheets and / or laminates, high-temperature resistance, wear resistance and the like, so that the bonding sheets and / or laminates can be isolated by the mirror steel plates, and the insulating panel can be easily separated from the mirror steel plates; release films are not required to be used during production, so that the problem of release agent residues is avoided, and the working procedure of release film tearing is not required to be carried out after the step of laminating is completed; the mirror steel plates can be directly reused, on the premise of ensuring the product quality, the production process is simplified, the production cost is reduced, and the pollution to the environment due to the use of the release films is avoided.

Description

technical field [0001] The invention relates to the technical field of insulating surface laminates, in particular to a production method of an insulating panel. Background technique [0002] Insulating surface laminates, which can be referred to as insulating panels, are mainly composed of two or more layers of resin-impregnated fibers or fabrics that are laminated and bonded by heat and pressure. Laminated products can be processed into various insulating and structural parts, which are widely used in motors, transformers, high and low voltage electrical appliances, electrical instruments and electronic equipment. [0003] During the manufacturing process of the insulating panel, the mirror steel plate is required to laminate the reinforcement material impregnated with resin. After the resin is melted at high temperature, it will be closely combined with the mirror steel plate through metal bonds and chemical bonds. After the temperature is lowered, the resin and the mirro...
