Abstract

The invention discloses a glass microsphere and glass fiber composite reinforced corrugated pipe and a production method of the glass microsphere and glass fiber composite reinforced corrugated pipe. A pipe body comprises an inner wall and an outer wall. The outer wall comprises wave crest sections and wave trough sections, wherein the wave crest sections and the wave trough sections are regularly spaced in sequence. The inner wall is formed by a smooth pipe body layer. A composite reinforced material of the outer wall contains glass microspheres and glass fibers. The production method of the glass microsphere and glass fiber composite reinforced corrugated pipe comprises the steps that the hollow glass microspheres and the chopped glass fibers are added into the composite reinforced material of the outer wall, and the color of the inner wall and the color of the outer wall are distinguished. The superfine glass microspheres in the corrugated pipe contain gas, are of a hollow structure, have the advantages of low heat conductivity coefficient, light weight, smooth surface and the like, and can be used for preparing pipes with good thermal insulation and mechanical properties. The glass fibers in the corrugated pipe have the advantages of high tensile strength, good heat resistance, heat insulation, sound insulation, flame retardance, acid and alkali resistance, excellent insulativity and the like, and can be used for preparing the heat-resistant, acid-resistant, alkali-resistant and high-strength pipes.

Description

technical field [0001] The invention belongs to the field of pipe production, and relates to a glass microsphere and glass fiber composite reinforced corrugated pipe and a production method thereof. Background technique [0002] High-density polyethylene double-wall corrugated pipe has been widely promoted and applied in my country in recent years, and its performance indicators can meet the national standards. It is a new type of pipe with a ring structure and smooth inner and outer walls. However, the double-wall corrugated pipes widely used in the market are low in strength, poor in compressive capacity, low in ring stiffness, low in drop hammer impact, and easy to break, which affects the practical value of the bellows. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing double-wall corrugated pipe products have insufficient functions and technologies, and provide a kind of simple molding, reasonable struc...
