Abstract

The invention discloses a weather-resistant power pipe. The weather-resistant power pipe is prepared from the following raw materials in parts by weight: 100-150 parts of polypropylene, 5-10 parts of light calcium carbonate, 1-8 parts of flaky talcum powder, 2-10 parts of calcined kaolin, 1-5 parts of brucite powder, 20-40 parts of modified silica fume, 0.2-3 parts of colorant, 2-10 parts of novel nucleating agent, 1-2.7 parts of antioxidant, 0.5-3 parts of polytetrafluoroethylene, 2-12 parts of toughening master batch, 5-20 parts of melamine cyanurate and 5-15 parts of modified crystal whisker; the preparation process of the novel nucleating agent comprises adding 150-180 parts of p-tert-butyl benzoic acid to 200-300ml of tetraisopropyl titanate, reacting at 90-130 DEG C for 3-5 hours and then adding 100-150ml of silicate ester to obtain a solution A, adding the solution A to an ethanol-water mixture, hydrolyzing at 50-65 DEG C for 3-5 hours, filtering and drying, thereby obtaining the novel nucleating agent. The weather-resistant power pipe is high in shock resistance, aging resistance, cold tolerance and thermal resistance.

Description

technical field [0001] The invention relates to the technical field of power tubes, in particular to a weather-resistant power tube. Background technique [0002] Polypropylene (PP) has a high melting point and excellent comprehensive properties. It is one of the most promising thermoplastic polymer materials today. Compared with other general-purpose thermoplastics, it has low density, good rigidity, high strength, flex resistance, and outstanding Stress cracking resistance, good heat resistance, electrical insulation and chemical resistance, and rich sources of raw materials, low price, easy to process and shape, have been widely used in chemical industry, electrical appliances, automobiles, construction, packaging and other industries, but Polypropylene material has a key weakness, that is, due to the existence of a large number of unstable tertiary carbon atoms in its molecular chain, in the presence of oxygen, only a small amount of energy can be used to remove the hydr...
