1results about How to "Improve toughening efficiency" patented technology

This invention discloses a heat- and impact-resistant protective conduit for MPP cables and its preparation method, relating to the field of polymer materials technology. The components, by weight, include: 20-22 parts of a toughening dispersion made from anhydrous ethanol and terminally epoxy-terminated hyperbranched polysiloxane; 33-35 parts of a boron-nitrogen co-doped carbon dot made from citric acid, boric acid, and urea, first compounded with phytic acid and piperazine, then compounded with modified zirconium phosphate prepared by hexadecyltrimethylammonium bromide intercalation, and then modified with silane coupling agent KH-560 to form a flame retardant synergist; 12-14 parts of polyolefin elastomer; 2-2.5 parts of magnesium aluminum hydrotalcite; 0.2-0.24 parts of antioxidant; 0.2-0.3 parts of calcium stearate; 0.2-0.3 parts of polyethylene wax; and 100-120 parts of polypropylene. The introduction of the flame retardant synergist and other raw materials in this invention effectively improves flame retardancy, aging resistance, impact resistance, low-temperature resistance, and heat resistance.
