|1. (WO2018127031) NEW-TYPE MIXED COMPOSITE PIPE, PREPARATION METHOD AND APPLICATION|
|Title:||NEW-TYPE MIXED COMPOSITE PIPE, PREPARATION METHOD AND APPLICATION|
A new-type mixed composite pipe, a preparation method and an application; a main body or structural layer of the new-type composite pipe uses a high polymer as a substrate, is mixed and solidified by one or more porous light aggregate materials, which are also called light bone materials or particles, and may be compounded with each non-metal material or each metal based pipe to prepare different new-type mixed composite pipes; the high polymer comprises a thermoset high polymer and a thermoplastic high polymer which may be combined with a porous particle reinforcing material. The pipe may be prepared and formed by means of at least one method from among rolling, winding, pultrusion, centrifugal casting, extrusion, injection molding, resin transfer, and sandwich structure. In addition to retaining the advantages of an original same-type composite pipe, the present invention may also solve the technical problems of pipe weight, delamination, insulation, shading, heat insulation, heat preservation and the like. The pipe may be applied in oil, natural gas, heating and gas supply, water supply and drainage, agricultural irrigation, mining, seawater desalination, electricity communication, municipal pipe galleries, and the like.
