Glass fiber reinforced plastic open-web plate with high corrosion resistance, and preparation method thereof

Abstract

The invention discloses a glass fiber reinforced plastic open-web plate with high corrosion resistance and a preparation method thereof. The glass fiber reinforced plastic open-web plate comprises a first open-web plate body, first positioning seats are fixedly arranged at the two ends of one side of the top of the first open-web plate body correspondingly, and first connecting rods are rotationally arranged on one sides of the two first positioning seats correspondingly; and second connecting rods are rotationally arranged at one ends of one sides of the two first connecting rods correspondingly, and second positioning seats are rotationally arranged at one ends of one sides of the two second connecting rods correspondingly. By rotating first positioning handles, two second gears of the two first gears drive the two first connecting rods, the two second connecting rods, two third connecting rods and two fourth connecting rods to be in linkage correspondingly, and the positions between a second hollow web plate and the first hollow web plate are changed, so the thickness of the hollow web plate is convenient to adjust, the hollow web plate is convenient to use in different occasions, the cost increase caused by thickness limitation in the use process is avoided, the material selection difficulty is reduced, and the practicability of the open-web plate is improved.

Description

Technical field [0001] The present invention relates to the field of FRP, and more particularly to a glass steel aerial belle plate with strong corrosion resistance and a preparation method thereof. Background technique [0002] FRP's famous fiber reinforced plastics, that is, fiber reinforced composite plastics. According to the different fibers divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, and the like. It is a composite material such as a substrate material with a glass fiber and its articles (glass cloth, belt, felt, yarn, etc.) to synthesize resins. The fiber reinforcing composite is composed of enhancement fibers and matrices. The diameter of the fiber (or whisker) is small, generally 10 μm or less, less defects, less than 30 minutes, is a brittle material, susceptible to damage, break, and corrosion. The matrix is ​​much lower relative to the fiber, but it can be sub...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, FRP hollow plates are usually used as surface materials. Commonly used FRP hollow plates are single-layer hollow plates, and it is difficult to change their thickness, which makes it difficult to select materials due to thickness restrictions during use, and FRP fasting The splicing between the plates is relatively complicated, which reduces the practicability of the FRP hollow plate, so there is a need for a FRP hollow plate with strong corrosion resistance and its preparation method
