Embodiment Construction

[0018] The MPP power pipe polymer of the present invention is composed of polypropylene, polyamide, toughening agent, weather resistance agent, antioxidant, and lubricant. Polypropylene is used as the MPP power pipe polymer base material, and its formula is: polypropylene: 60~ 90 parts, polyamide: 0-25 parts, toughening agent: 0-20 parts, weather resistance agent: 0.2-0.6 parts, antioxidant: 0.2-0.6 parts, lubricant: 0.4-1.5 parts. The formula is shown in Table 1 in the embodiment of the present invention.

[0019] Among them, polypropylene is extrusion-grade polypropylene, which is block copolymerized polypropylene (PP-B) or random copolymerized polypropylene (PP-R), or a blend of the two, PP-R is preferred, and specific requirements For: the molecular weight is 80-1.2 million, and the melt flow index is 0.5-3.5g / 10min.

[0020] Polyamide is extrusion-grade polyamide, polyamide 6 (PA6) or polyamide 66 (PA66), or a blend of the two, preferably PA6. The specific requirements ...

Abstract

The invention relates to a preparation method of an MPP electric power pipe polymer. Polypropylene is used as a base material of the MPP electric power pipe polymer, and the method comprises the following steps that firstly, 60-90 parts of the polypropylene, 0-25 parts of polyamides, 0-20 parts of flexibilizers, 0.2-0.6 part of weather resistant agents, 0.2-0.6 part of antioxidant and 0.4-1.5 parts of lubricating agents are put into a high-speed mixer together, the stirring speed is 600-1000 r / min, constant-speed stirring is conducted for 1-3 min, and a blend is obtained; and secondly, the blend obtained in the step 1 is put into a double-screw extruding machine, the processes of fusing, plasticizing, shearing and pelleting are conducted, and the MPP electric power pipe polymer is obtained. According to the preparation method of the MPP electric power pipe polymer in the technical scheme, the PP is used as the base material and blended with other plastics, the impact strength can be improved by 2-3 times, the polymer can be used as impact-resistant shell materials, the formula design of the MPP electric power pipe polymer is simple, the performance influencing factors of the prepared electric power pipe polymer are little, and the product performance is stable.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an MPP power pipe polymer and a preparation method thereof. Background technique [0002] With the promotion of new energy technology and the prospect of the charging pile market becoming more and more clear, the market demand for power cable protection tubes (referred to as power tubes) is increasing. The application proportion of digging power pipes has risen sharply. [0003] Because MPP power pipes have the advantages of high temperature resistance, external pressure resistance, and cold resistance, compared with ordinary PP pipes and PE pipes, the overall performance is better, but the cost is higher. For the modified MPP power tube, optimizing formula, improving production efficiency, reducing the cost of MPP power tube and improving product performance stability are key technical issues. [0004] Chinese patents No. ZL201410326122.X and No. ZL201210431879.6 disclose so...
