Embodiment 1

[0044] The nano gas-conducting film of the present invention is produced by Xiamen Haoer New Material Co., Ltd., and its preparation method is as follows:

[0045] Follow the steps below:

[0046] (1) Weigh the following components in parts by weight, stir and mix evenly to obtain a mixture;

[0047] Epoxy resin 30-60;

[0048] Phenolic resin 20-30;

[0049] Latent curing agent 5-15;

[0050] Accelerator 0.5-3;

[0051] Amine curing agent 1-20;

[0052] Nano filler 0.1-4;

[0053] Solvent 0-30;

[0054] (2) Coating the mixture obtained in step (1) on the release substrate;

[0055] (3) When the weight part of the solvent is 0, the surface of the coated mixture in step (2) is covered with a layer of release substrate, forming the mixture as the middle layer, and the release substrate as the upper, A sheet with a lower surface layer structure; when the weight part of the solvent is greater than 0 and less than or equal to 30, first dry the mixture coated in step (2), and...

Embodiment 2

[0058] A nano air-conducting fiber membrane used to improve the appearance of fiber composites, the preparation method of which is as follows:

[0059] First, tear off the release layer (PE release film) on one side of the nano air-conducting film covered with the upper and lower release layers (the upper and lower release layers are respectively PE release film and release paper), and set aside; Paste the exposed nano air-conducting film surface on the fiber dry cloth, and paste another exposed nano-air-conducting film surface on the other side of the fiber dry cloth (keep the release paper on the other side), and finally paste it through the compound machine made.

[0060] The method for producing fiber composite pipe products using the nano air-conducting fiber membrane is as follows:

[0061] (1) The diameter of the pipe is 2cm, the length is 50cm, and the raw materials are cut according to the size of the pipe, including the nano air-conducting fiber membrane;

[0062] ...

Embodiment 3

[0066] A nano air-conducting fiber membrane used to improve the appearance of fiber composites, the preparation method of which is as follows:

[0067] First, tear off the release layer (PE release film) on one side of the nano air-conducting film covered with the upper and lower release layers (the upper and lower release layers are respectively PE release film and release paper), and set aside; Generally, the structure of the prepreg fiber cloth purchased on the market is: release layer (polyethylene film material) / fiber cloth impregnated with resin / release layer (release paper material). The layer (polyethylene film) is torn off first, and then bonded to the exposed nano-air-conducting film surface; the exposed nano-air-conducting film surface is pasted on the exposed fiber prepreg, and the release of the fiber prepreg The layer (polyethylene film material) has been torn off, and the release layer (release paper material) on the other side is still retained, and finally bon...

Abstract

The invention relates to a nanometer air guide fiber membrane for improving fiber composite material appearance and a preparation method and application thereof. The nanometer air guide fiber membrane comprises release layers which are arranged on the upper surface and the lower surface respectively, a nanometer air guide membrane layer and a fiber cloth layer which are arranged between the upper release layer and the lower release layer. According to the nanometer air guide fiber membrane for improving the fiber composite material appearance, the phenomena that the appearance in the original product is out of flatness, lack of glue and has pinholes are overcome, excess gas is exported by the nanometer air guide membrane, at the same time, by means of the composite structure of the nanometer air guide membrane and the fiber cloth, the introduction of the gas between layers is effectively reduced, the preparation method is simple, the technological process is short, the forming way is diversified, and it is beneficial to obtaining a full and smooth appearance, the quality and yield rate of the product are improved.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a nano air-conducting fiber membrane for improving the appearance of fiber composite materials, a preparation method and application thereof. Background technique [0002] At present, all products made of fiber composite materials, such as tennis rackets, bicycles, drones, bats, etc., are affected by changes in molds, materials, release agents, air pressure and weather during the production process. There will be unevenness, lack of material, and pinholes on the rear surface, especially when some products require special surface textures. Once the product has the above-mentioned poor appearance, the product will become a substandard product. Even if it does not cause scrapping, the appearance needs to be repaired. Currently Each production factory adopts the follow-up cumbersome soil filling process to make up for it, so as to meet the requirements of repairing the appearance. ...
