Abstract

The invention discloses a preparation method of a fiberglass pipeline. The preparation method is characterized by comprising the following steps of a) preparing a fiberglass pipeline lining layer, wherein a wear-resistant rubber coating is coated on the surface of a fiberglass core mold; b) winding, wherein glass fiber infiltrated with unsaturated polyester resin is repeatedly wound onto the lining layer through fiberglass pipeline winding equipment; c) a curing process; and d) preparing an outer protective layer. The preparation method of the fiberglass pipeline enables the produced glass pipeline to have higher strength and rigidity.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastic pipe manufacturing devices, and in particular relates to a method for preparing a glass fiber reinforced plastic pipe. Background technique [0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is a glass fiber with a resin matrix weight that is wound on a rotating mandrel layer by layer according to the process requirements. [0003] The existing glass pipe production process not only has a complicated operation process, but also produces products with poor strength and rigidity. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the invention provides a method for preparing a glass fiber reinforced plastic pipe with high product rigidity and high strength. [0005] In order to achieve the above object, the present invention adopts the following technical scheme: a preparation method of FRP p...
