Example Embodiment

[0033] The embodiment of the polyvinyl chloride power sheath pipe of the present invention consists of the following raw materials in parts by weight:

[0034] 100 parts polyvinyl chloride resin

[0035] Heat stabilizer 0.5-5 parts

[0036] Heat-resistant modifier 3-10 parts

[0037] Rigid modifier 5-20 parts

[0038] Lubricant 0.5-5 parts

[0039] Processing aid 0.5-5 parts

[0040] Filler 0-25 parts

[0041] Impact modifier 0-8 parts

[0042] Pigment 0-5 parts.

[0043] This embodiment aims at some deficiencies in the existing heat-resistant PVC, and provides a high-Vicat polyvinyl chloride power sheathing pipe, which takes into account both Vicat heat resistance and physical and mechanical properties, and has good molding and processing performance. The above components adopt multi-component compounding technology and play a synergistic role, especially the introduction of rigidity modifiers, which effectively reduces the number of heat-resistant modifiers added, and...

Abstract

The invention relates to the technical field of an electric power protecting sleeve, in particular to a polrvinyl chloride electric power protecting sleeve which is good in heat resistance and processing performance and a processing method of the polrvinyl chloride electric power protecting sleeve. The polrvinyl chloride electric power protecting sleeve comprises the following components in part by weight: 100 parts of polyvinyl chloride resin, 0.5-5 parts of heat stabilizer, 3-10 parts of heat-resistant modifier, 5-20 parts of rigidity modifier, 0.5-5 parts of lubricant, 0.5-5 parts of processing agent, 0-25 parts of filler, 0-8 parts of impact-resistant modifier and 0-5 parts of pigment. The vicat performance and the heat resistance of materials can be improved due to the collaborative reinforcement of the heat-resistant modifier and rigidity-reinforcing and toughness-increasing particles; the adding parts of the heat-resistant modifier can be effectively reduced since each component adopts a multi-formulation technology and collaboratively takes effects, and the rigidity modifier is introduced particularly; and the rigidity, the heat resistance and the impact-resistant strength of a system can be increased.

Description

technical field [0001] The invention relates to the technical field of electric power sheath pipes, in particular to a polyvinyl chloride electric power sheath pipe with excellent heat resistance and processing performance and a processing method thereof. Background technique [0002] With the successive development of old city renovations in major cities across the country and the requirements of new urban construction planning, it has become the general trend to bury urban high-voltage lines. In the construction process of burying high-voltage lines, it is necessary to add insulating sleeves, which means a huge market for the majority of plastic pipe manufacturers. [0003] In the production of such pipes, the raw materials usually used by plastic pipe manufacturers mainly include CPVC (chlorinated polyvinyl chloride) and PVC (polyvinyl chloride). Among them, CPVC has the defects of poor fluidity and difficult processing, while domestic CPVC resin powder is still immature...
