Preparation device for solid buoyancy material component epoxy resin related prepreg

Abstract

The invention relates to the field of epoxy resin processing, and particularly relates to a preparation device for a solid buoyancy material component epoxy resin related prepreg. The invention aims to provide the preparation device for the solid buoyancy material component epoxy resin related prepreg. According to the technical scheme, the preparation device for the solid buoyancy material component epoxy resin related prepreg comprises a clamping and fixing assembly, a coating assembly, a sizing assembly, a gluing assembly, a second supporting column, a third supporting column and a controller; and the controller is fixedly connected with the third supporting column. When the preparation device is used, the two sides of the surface of the glass fiber cloth are uniformly covered with liquid epoxy resin, then sizing is conducted, then the two sides of the sized glass fiber cloth are glued at the same time, a large amount of treatment waiting time is saved, meanwhile, the situation of seams is avoided through gluing on the two sides, the follow-up treatment difficulty is reduced, and the firmness problem is avoided.

Description

technical field [0001] The invention relates to the field of epoxy resin processing, in particular to a device for preparing prepregs related to epoxy resin as a solid buoyancy material component. Background technique [0002] Epoxy resin is a high molecular polymer, which refers to the general term for a class of polymers containing more than two epoxy groups in the molecule. It is a polycondensation product of epichlorohydrin and bisphenol A or polyols. Due to the ring The chemical activity of the oxygen group can be opened by a variety of compounds containing active hydrogen, and cured and crosslinked to form a network structure. Therefore, it is a thermosetting resin. Bisphenol A epoxy resin is not only the largest in output, but also the most complete in variety. Moreover, new modified varieties are still increasing, and the quality is constantly improving. [0003] In the prior art, when producing an epoxy resin prepreg, the glass fiber cloth is placed inside the mold...

Problems solved by technology

[0005] In order to overcome that when producing an epoxy resin prepreg, the glass fiber cloth is placed inside the mold for clamping. The inside of the mold has a tooth-like structure, which makes the glass fiber cloth deform and forms a continuous gap between the upper surface and the lower surface of the glass fiber cloth. Inject liquid epoxy resin into the mold to make it adhere to the surface of the glass fiber cloth, and wait for the epoxy resin to cool and solidify, so that the shape of the glass fiber cloth is hardened and finalized, and then the glass fiber cloth is taken out and turned over , the same operation is also performed on the other side of the glass fiber cloth. The shaped glass fiber cloth enters the mold again for gluing, and injects liquid epoxy resin into the mold until the epoxy resin fills the inside of the V-shaped surface. And protrude from the top of the V-shaped surface, wait for the epoxy resin to cool and solidify, then take out the glass fiber cloth and turn it over to face the glass fiber cloth, and perform the same operation on the other side. When shaping and gluing the glass fiber cloth, it can only be done once. One side is processed. After the processing is completed, it needs to be taken out and turned over again for processing. The waiting process wastes a lot of time. After deforming the glass fiber cloth and injecting epoxy resin, it cannot be guaranteed that the surface of the glass fiber cloth is evenly covered with epoxy resin. Poor, the gluing is carried out twice, there will be a subsequent processing process at the seam, and there may be problems in the bonding firmness after curing. The technical problem of the present invention is: to provide a solid buoyancy material component epoxy resin related Prepreg preparation device
