Problems solved by technology

The disadvantage is that thermosetting plastics have poor corrosion resistance and are prone to aging and failure; the bonding force between plastics and steel pipes is low, and they are prone to deformation and falling off
[0007] Although the above-mentioned composite pipes have improved the wear of traditional metal pipes in the process of conveying materials to varying degrees, they all have their own insurmountable defects

Embodiment 1

[0040] Refer to attached figure 1 , weigh 50 kg of 180-mesh industrial alumina particles, immerse in an aqueous solution containing KH-550 silane coupling agent with a mass fraction of 5%, stir for 1 hour, filter and dry; 1000 parts of 4,4'-diphenyl A mixture of methane diisocyanate (MDI) and 500 parts of polyester diol as a polyurethane prepolymer, mixed with the above-mentioned pretreated alumina particles, stirred for 2 hours and then added 80 parts of 1,4-butanediol (BD) , after uniform stirring, the polyurethane liquid castable is obtained.

[0041] refer to figure 2 , image 3 and Figure 4 , the manufacture of composite material-lined metal pipes: first evenly paint a layer of rubber-metal adhesive on the inner wall of the stainless steel seamless steel pipe, that is, the outer casing 1, and then place it on four rollers 5 in a large oven, among which A drum rotates at 300 rpm. When the jacket steel pipe is heated to 90°C, keep the constant temperature, extend int...

Embodiment 2

[0044] Refer to attachedfigure 1 , weighing 100 kg of 300-mesh industrial quartz sand particles, immersed in an aqueous solution containing 5% KH-550 silane coupling agent, stirred for 1 hour, filtered and dried; 1000 parts of M5050 type Polyurethane prepolymer (the main component is 4,4'-diphenylmethane diisocyanate), mixed with the above-mentioned pretreated quartz sand particles, stirred for 1.5 hours and then added 50 parts of 1,4-butanediol (BD), After uniform stirring, the polyurethane liquid castable is prepared.

Abstract

The invention discloses a ceramics particle strengthened composite material lining metal tube and a manufacturing method thereof, belonging to the field of composite wear-resistant tubes. 4,4-Diphenylmethane diisocyanate (MDI), polyester glycol, 1,4-butanediol (BD), ceramics particles and the like serve as raw materials to prepare composite material liquid castables, and a centrifugal casting technology is adopted to cast polyurethane base ceramics particle strengthened composite material lining layers on the inner wall of an outer thimble. The invention has the beneficial effect that the prepared ceramics particle strengthened composite material lining metal tube has excellent abrasive resistance and corrosion-resistance and greatly improves service life. The raw materials of the invention are easy to be obtained, manufacturing technology is simple, cost is low and economic benefit is obvious and practical application and mass production are beneficial for factories.

Description

technical field [0001] The invention relates to a composite wear-resistant pipe. Specifically, the invention relates to a ceramic particle reinforced composite material-lined metal pipe and a manufacturing method thereof. In particular, it relates to the manufacturing process of the metal pipe with the polyurethane-based ceramic particle composite material as the inner liner. Background technique [0002] In various industries such as mining and metallurgy, there are many processes such as pit backfilling, mineral transportation, waste treatment, sand excavation, ore cleaning, coal ash transportation, etc., which require long-distance transportation of large amounts of solid materials or mixed solid-liquid slurries , These materials or slurries contain a large amount of high-hardness lumpy or granular solids, so the corresponding conveying pipelines are facing serious wear problems. In these industrial applications, not only the strength and toughness of the pipeline are r...
