Glass fiber reinforced plastic fan shell and preparation method thereof

Abstract

The invention discloses a glass fiber reinforced plastic fan shell and a preparation method thereof, and belongs to the field of fan shell processing, the glass fiber reinforced plastic fan shell comprises, by weight, 30%-34% of resin, 20%-24% of glass fiber reinforced plastic fibers, 39%-42% of calcium carbonate, 5% of polystyrene, 1%-2% of accelerant, 1%-2% of curing agent and 0.3%-0.8% of pigment, and a layer of PE film is laid on a conveying belt of a sheet machine; resin, calcium carbonate and polystyrene are stirred into paste according to the weight percentage, then the paste is rolled into resin sheets through a roller in a sheet machine, and the resin sheets are laid on the PE thin film; uniformly scattering glass fibers on the first layer of sheet, covering a layer of resin sheet made of resin, calcium carbonate and polystyrene, and pasting a layer of PE film on the sheet; and rolling into glass fiber reinforced plastic raw material sheets through a roller in a sheet machine. The fan shell has the beneficial effects that the resin, the calcium carbonate and the polystyrene are mixed and pressed into the sheets, and then a layer of glass fiber is laid between the two sheets, so that the obtained fan shell is outstanding in hardness, tensile strength and acid and alkali corrosion resistance.

Description

technical field [0001] The invention relates to the field of fan shell processing, in particular to a glass fiber reinforced plastic fan shell and a preparation method thereof. Background technique [0002] The casing of the fan used to be stamped and formed by thin steel plate. Due to the moisture in the air, the fan will be used for a long time, and the paint on the casing will rust after falling off, which will affect its service life. Now use glass fiber reinforced plastic to form, and there will be no rust. FRP fan housing is pasted and formed. Compared with the fan housing formed by thin steel plate, it has the characteristics of compact structure, beautiful appearance, simple processing procedure, low manufacturing cost and long service life. [0003] The shape of the FRP fan casing is like a snail shell. The hand lay-up process is as follows: first cut the glass cloth according to the shape and size of the product, clean the surface of the punch or die, and then app...

AI Technical Summary

Problems solved by technology

The fan casing made by this process has the characteristics of low hardness, poor tensile strength, and poor acid and alkali corrosion resistance.

[0004] The invention patent application with the publication number CN107163496A discloses a waterproof and heat-resistant material for the fan casing. -Phenyl-2-propyl acrylate 4-6, epoxy vinyl ester resin 8-16, 2-hydroxyethyl cellulose 2-5, diazolone 0.2-0.6, cristobalite 2-5, the The fiber material is carbon fiber, which has the characteristics of light weight, high strength and good waterproof performance, but its performance in hardness, tensile strength and acid and alkali corrosion resistance is not outstanding
