Title:
LAMINATED INORGANIC PIPELINE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/006959
Kind Code:
A1
Abstract:
A laminated inorganic pipeline for fluid transport, comprising a first diameter pipeline (7) and a second diameter pipeline (8) with different diameters. The second diameter pipeline (8) is sleeved on the periphery of the first diameter pipeline (7) to form the laminated inorganic pipeline; a central hole is formed in the first diameter pipeline (7); an interlayer is formed between the first diameter pipeline (7) and the second diameter pipeline (8); the interlayer is filled with slurry, and the slurry solidifies to form a polymer middle layer (10); the slurry comprises a prepolymer and inorganic modified powder, and the mass ratio of the prepolymer to the inorganic modified powder is 1:(0.01-3.0). The laminated inorganic pipeline has good impact resistance and safety.
