Abstract

The invention discloses an anti-aging MPP (modified polypropylene) electric tube which 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 flake talcum powder, 2-10 parts of calcined kaolin, 1-5 parts of brucite powder, 20-40 parts of modified micro silicon powder, 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 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 the following steps: adding 150-180 parts of p-tert-butyl benzoic acid into 200-300ml of tetraisopropyl titanate, reacting at 90-130 DEG C for 3-5 hours, adding 100-150ml of silicate to obtain a solution A, adding the solution A into an ethanol-water mixture, hydrolyzing at 50-65 DEG C for 3-5 hours, filtering, and drying to obtain the novel nucleating agent. The anti-aging MPP electric tube has the advantages of high aging resistance, excellent impact resistance, excellent freezing resistance and excellent heat resistance.
