Abstract

The invention provides a reinforced polyethylene composite pipe and a preparation method thereof, and relates to the technical field of polymer materials. The reinforced polyethylene composite pipe of the present invention is made of the following raw materials: polypropylene, acrylate, tert-butylamine, nano-carbon fiber, filler, glass beads, white oil, ethanol, antistatic masterbatch, flame retardant, antioxidant, coupler joint agent. The enhanced polyethylene composite pipe of the present invention has high surface hardness, is not easy to be oxidized, has high mechanical strength, and has good impact resistance, so that the pipe is not easy to crack when it directly contacts with sharp stones, thereby increasing the pipe material in non-opening applications. The safety in digging and laying also greatly prolongs the service life of the pipe.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a reinforced polyethylene composite pipe and a preparation method thereof. Background technique [0002] At present, with the rapid development of my country's housing industry and the continuous advancement of urban construction and western development, investment in urban infrastructure construction continues to increase, bringing huge market demand for plastic pipes. However, people have found in the process of using plastic pipes that ordinary plastic pipes have some disadvantages in the construction, installation and use of pipes due to their own materials. For example, for PP-R pipes, the material itself is relatively brittle and has poor wear resistance. During transportation and installation, it is easy to scratch the surface of the pipe, affecting the appearance quality and appearance of the pipe surface. In severe cases, it will also affect the pipe surface. ...
