Embodiment 1

[0054] Such as figure 1 As shown, the present embodiment provides a paint prefabricated film, including a paint prefabricated film substrate and a paint coating 1, and the paint prefabricated film substrate includes a stacked substrate layer 2, a back adhesive layer 3 and a release paper 4, wherein The surface of the base material layer 2 away from the adhesive layer 3 is a smooth plane, the paint coating 1 is arranged on the smooth plane, and the surface of the base material layer 2 facing the adhesive layer 3 is provided with several protrusions 5 .

[0055] The above-mentioned paint prefabricated film, because the surface of the base substrate layer 2 away from the adhesive layer 3 is a smooth plane, the smooth plane has a smaller surface tension, so the wettability is better, thereby forming a paint coating on the smooth surface 1 can make the thickness of the paint coating 1 more uniform, and there are fewer internal defects, so the quality is higher; at the same time, th...

Embodiment 2

[0065] The present embodiment provides a kind of protective structure, uses the paint prefabricated film that embodiment 1 provides, and its preparation method comprises the following steps:

[0066] (1) The release paper 4 of the paint prefabricated film is torn off, and some paint prefabricated films are pasted on the inner surface of the protective structure mold by the adhesive layer 3;

[0067] (2) forming the first fiber material layer on the paint prefabricated film;

[0068] (3) Under vacuum conditions, form a first resin material in the first fiber material layer and solidify it to obtain the first fiber reinforcement material layer 6;

[0069] (4) After the first resin material is cured, the paint coating 1 is physically separated from the substrate layer 2 under the action of an external force to obtain a protective structure.

[0070] In the preparation method of the above-mentioned protective structure, under vacuum conditions, the air present at the interface be...

Embodiment 3

[0096] This embodiment provides a method for preparing a protective structure, using the paint prefabricated film provided in Example 1, comprising the following steps:

[0097] (1) tear off the release paper 4 of the paint prefabricated film, and paste some paint prefabricated films on the inner surface of the protective structure mold (the inner surface of the protective structure mold is the same shape as the inner surface of the wind power blade mould) by the adhesive layer 3, wherein , 250mm away from the front edge 81 of the protective structure mold and the edge 82 of the protective structure mold, no paint prefabricated film is pasted, and adjacent paint prefabricated films are butted;

[0098] (2) Lay glass fibers on the paint coating 1, the fiber form is a chopped fiber mat, and when the vacuum degree is 40mbar, deposit in the glass fibers and at the interface between the glass fibers and the release cloth by a vacuum infusion molding process epoxy resin, and it is c...

Abstract

The invention provides a paint prefabricated film, a protection structure and a preparation method of the protection structure. The surface, deviated from a back glue layer, of a substrate base material layer is a smooth plane, the smooth plane has the relatively low surface tension, and a paint coating formed on the surface of the smooth plane can be more uniform in thickness and fewer in insidedefects, so that the quality is higher; a plurality of bulge parts are arranged on the surface, facing the back glue layer, of the substrate base material layer, so that the binding force of the substrate base material layer and the paint coating is smaller than that of the substrate base material layer and the back glue layer, separation of the paint coating from a paint prefabricated film base body can be realized by the aid of the external force, and the paint coating is used for protecting the outer surface of a wind turbine blade base body. The paint prefabricated film is applied to preparation of the wind turbine blade protection structure, and the large-area damage to the paint coating due to sand erosion and rain erosion of the area having the low thickness of the paint coating dueto the non-uniform thickness of the paint coating can be avoided, so that the protection effect of the protection structure can be improved.

Description

technical field [0001] The invention relates to the field of wind power blades, in particular to a paint prefabricated film, a protective structure and a preparation method thereof. Background technique [0002] As a clean and renewable energy, wind energy has attracted more and more attention from all over the world. The effective use of wind energy will help realize the diversification of energy structure and reduce environmental pollution. The designed service life of wind turbine blades is 20 years. Once the wind turbine blades start to operate, they will be corroded by rain, wind and sand, and the atmosphere, and they will also be subjected to strong ultraviolet aging. During the high-speed operation of the blades, the erosion of wind power blades by wind, sand and raindrops is equivalent to plasma cutting, and cavities are easily formed on the surface of the blades. Studies have shown that the increase in blade surface roughness and the accumulation of defects will le...
