Description

technical field

[0001] The invention relates to the technical field of plastic pipes, in particular to a rapidly prototyping PVC-U pipe and a preparation method thereof. Background technique

[0002] PVC-U pipe, also known as hard PVC, is made of polyvinyl chloride resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, plasticizer, etc., and is extruded by a plastic extruder or injected by an injection molding machine. As a plastic product for construction, PVC-U pipes have developed rapidly, especially in some developed countries, where their total consumption has accounted for 80% to 90% of plastic pipes, but the melt viscosity of PVC-U pipes is high. Poor performance, the molding temperature of the resin is close to the thermal decomposition temperature, the temperature range that can be molded is very narrow, and it is difficult to mold.
