However, PP is prone to brittle failure in low temperature environment, which affects the service life. At the same time, during the pipeline construction process, due to the movement of the pipeline and the contact with the ground, the wear resistance of PE, PP or PVC is not good, so that the surface of the pipeline is damaged. It is often damaged and damaged during loading, unloading and construction, which will affect the performance of pipes

[0036] A method for preparing a wear-resistant carat tube, comprising weighing polypropylene, nylon, fumed silica, polysilicone, anti-aging agent, dispersant, toughening agent, compatibilizer and coupler according to the weight parts Joint agent; polypropylene, nylon and compatibilizer are mixed and extruded to obtain polypropylene nylon alloymasterbatch; then the polypropylene nylon alloymasterbatch is mixed with fumed silica, polysilicone, anti-aging agent, dispersant, toughening agent and coupling agent are mixed, extruded and granulated to obtain the special material for the carat tube; finally, the special material for the carat tube is formed to obtain the carat tube.
[0037] Further, the mixing specifically includes: stirring the raw materials at 20-30° C. for 3-8 minutes at a stirring speed of 800-1000 r / min.
[0038] It can be seen from the above description that stirring the mixture at a high speed can make it evenly mixed.
[0043] Please refer to figure 1 , Embodiment 1 of the present invention is: a wear-resistant carat tube, comprising the following raw materials in parts by weight:
[0053] In this embodiment, the coupling agent is γ-aminopropyltriethoxysilane, the compatibilizer is acrylic acid grafted polypropylene, the dispersant is a higher fatty acidamide compound, and the toughening agent It is EPDM rubber, and the anti-aging agent is hindered amines.
[0054] The preparation method of carat tube comprises the steps:
[0055] 1) Weigh polypropylene, nylon, and compatibilizer according to the weight of each raw material in the formula, put them in ...
Embodiment 2
[0060] The difference between embodiment two of the present invention and embodiment one is that the weight parts of raw materials in embodiment two are:

Abstract
The invention discloses an abrasion-resistant Carat tube and a preparation method thereof. The abrasion-resistant Carat tube comprises the following raw materials by weight: 77-83 parts of polypropylene, 8.1-8.4 parts of nylon, 2-3.6 parts of fumed silica, 2-2.7 parts of silicones, 0.1-0.4 parts of a coupling agent, 1-2.7 parts of a compatilizer, 0.2-0.5 parts of an antiaging agent, 0.2-0.5 parts of a dispersing agent, and 3.1-4.5 parts of a flexibilizer. The nylon is added to the raw materials, so the rigidity and abrasive resistance of the Carat tube can be improved; the fumed silica and silicones are added, so the weather resistance and the wear-resisting property are improved; ethylene propylene diene terpolymer rubber is added as the flexibilizer for increasing the aging-resistant performances, such as heat-resistance and weather-resistance, of the Carat tube; and the polypropylene (PP) is used as the main raw material, the weight of the prepared tube is light, the physical property and the chemical property are excellent, and the application prospect is good.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a wear-resistant carat tube and a preparation method thereof. Background technique [0002] At present, the raw materials used for buried drainage and sewage pipelines in the domestic market are mainly polyvinyl chloride (PVC) and high-density polyethylene (HDPE). With the improvement of environmental protection awareness, the use of modified polyvinyl chloride (UPVC) as sewage pipes is less and less. Polypropylene (PP) buried drainage and sewage pipes have the following advantages over traditional buried drainage pipes: low density, light weight, easy construction, low cost, higher cost performance, and no need for large installation equipment at the construction site , its construction efficiency and safety are higher; various connection methods such as sockets, sleeves, and hot melt can be used to facilitate the construction of non-excavation long-distance drainage ...
