Abstract

The invention discloses a convex rib winding reinforced polyvinyl chloride hose for sand transportation and a preparation method thereof. The convex rib winding reinforced polyvinyl chloride hose for sand transportation is prepared from a polyvinyl chloride soft mixture and a polyvinyl chloride hard mixture, wherein the polyvinyl chloride soft mixture is prepared from suspension-process polyvinylchloride, high-molecular-weight polyvinyl chloride, plasticizer, anti-shock modifier, toughener, processing modifier, organotin stabilizer, calcium-zinc composite stabilizer, rare-earth stabilizer, lubricant, light stabilizer, filler and other assistants; and the polyvinyl chloride hard mixture is prepared from suspension-process polyvinyl chloride, chlorinated polyvinyl chloride, anti-shock modifier, toughener, processing modifier, organotin stabilizer, calcium-zinc composite stabilizer, lubricant, light stabilizer, filler and other assistants. The product prepared by the technical scheme ofthe invention has the advantages of favorable wear resistance, heat resistance, freezing resistance, fatigue resistance, bending resistance, energy saving and low cost, and is a new product expected in sand transportation industry.

Description

technical field [0001] The invention relates to a pipe material for sand transportation and a preparation method thereof, in particular to a rib-wound reinforced polyvinyl chloride hose for sand transportation and a preparation method thereof. Background technique [0002] At present, the sand conveying pipes are mainly steel pipes and rubber pipes, and the steel pipes and rubber pipes are used for sand conveying. The main defects in their performance are: [0003] 1. The connection and use flexibility of the steel pipe is poor, the corrosion resistance and wear resistance are poor, and the service life is relatively short. [0004] 2. The transparency of the rubber tube is poor, it is not convenient to observe the flow of materials and deal with related faults, and the processing cost is relatively high. [0005] In view of the current further requirements on the wear resistance, transparency and processing cost of sand conveying pipes, it is necessary to further develop s...
