Problems solved by technology

Material scientists have adopted various technologies to increase the service life of metal materials. Many people use surface coating, surface treatment, and even composite with ceramics, but the effect is still unsatisfactory so far.
There are still many people trying to use inorganic non-metallic materials such as ceramics and glass to replace metals, but their high brittleness makes it difficult to make breakthroughs.
Some people try to use FRP to replace metal, but its low temperature resistance and poor aging resistance make it difficult to completely replace metal materials.

Abstract

The invention discloses a high-strength wear-resisting antiseptic anti-seismic composite microcrystal pipeline and a preparation method thereof. The high-strength wear-resisting antiseptic anti-seismic composite microcrystal pipeline is divided into inner and outer layers, wherein the inner layer is a glass ceramic pipe, and the outer layer is microcrystal fiber reinforced plastic which is formed by compounding microcrystal glass fiber cloth and epoxy resin. The preparation method comprises the following steps of (1) selecting raw materials according to the component proportion of the glass ceramic pipe and microcrystal glass fiber to perform melting to obtain molten glass metal; (2) preparing the glass ceramic pipe; (3) preparing the microcrystal glass fiber cloth; and (4) winding the outside of the glass ceramic pipe with the microcrystal glass fiber cloth having the thickness of 1-8mm and coating with the epoxy resin, and then curing for molding. The impact resistance and pressure resistance of the composite microcrystal pipeline provided by the invention are superior to those of a single glass ceramic pipeline; the composite microcrystal pipeline has high strength, high toughness, high wearing resistance, high antiseptic performance and high anti-seismic performance, and can be applied to the fields of petroleum, natural gas, chemical industry, mine, power plants, cement plants, submarine cables, tap water, war industry and the like.

technical field [0001] The invention relates to a high-strength, wear-resistant, anti-corrosion and anti-seismic composite microcrystalline pipe and a preparation method thereof, which belong to the technical field of application of microcrystalline glass. Background technique [0002] Metal pipes, especially alloy steel pipes, are widely used in many fields. However, the anti-corrosion and wear-resistant problem of metal has become a difficulty restricting its development. Material scientists have adopted various techniques to increase the service life of metal materials. Many people have used surface coating, surface treatment, and even composited with ceramics, but the results are still unsatisfactory. There are also many people trying to replace metals with inorganic non-metallic materials such as ceramics and glass, but their brittleness is relatively large and it is difficult to make breakthroughs. Some people try to use FRP to replace metal, but its low temperature ...
