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.

This utility model discloses a flat, fire-resistant, silicone rubber flame-retardant cable, relating to the field of cable technology. It includes a cable core composed of multiple sets of parallel-distributed wire cores, each core comprising a conductor, an insulation layer, and a shielding layer. A fire-resistant layer, a flame-retardant layer, and an outer sheath are sequentially disposed outside the cable core. The fire-resistant layer consists of a hardened inner layer and a high-temperature resistant outer layer. The hardened inner layer is a ceramicized silicone rubber layer, and the high-temperature resistant outer layer is a mica tape wrapping layer. The flame-retardant layer consists of a buffer layer and a flame-retardant outer coating layer. The buffer layer is aluminum hydroxide-filled silicone rubber, and the flame-retardant outer coating is an intumescent flame-retardant coating. This solution solves the problems of unstable cable operation in high-temperature environments and performance degradation in complex environments.

This utility model relates to the field of casual shoe processing technology, and in particular to a hot-melt device for a casual shoe toe heat fusion machine. It includes a base plate, a lower mold, and an upper mold. The upper end of the outer wall of the base plate is fixedly connected to the lower mold via a bracket. A casual shoe toe pressing and hot-melt structure is provided in the middle of the upper end of the outer wall of the base plate, and a shoe last support structure is provided in the middle of the lower end of the outer wall of the lower mold. This hot-melt device for a casual shoe toe heat fusion machine utilizes the casual shoe toe pressing and hot-melt structure. Two motors start simultaneously, driving a spool to rotate within the housing via bearings. The spool then winds up a cable. During this process, the cable pulls a vertical rod to slide downwards within the lower mold, which in turn moves the upper mold downwards. The motor-driven spool rotates to wind up the cable, causing the mold to adhere to the shoe toe on the lower mold. This avoids the need for manual pressing of the mold to heat-melt the casual shoe toe in existing technologies, thus effectively improving practicality.

This invention relates to the field of coating technology, and more specifically, to an exposed hydrophobic flame-retardant fireproof coating, comprising the following steps: preparation of caffeic acid-intercalated calcium aluminum lanthanum hydrotalcite, preparation of a water-resistant flame-retardant composite, preparation of modified sodium lignosulfonate, and preparation of the exposed hydrophobic flame-retardant fireproof coating. The water-resistant flame-retardant composite effectively utilizes the flame-retardant properties of the caffeic acid-intercalated calcium aluminum lanthanum hydrotalcite. During high-temperature combustion, the caffeic acid-intercalated calcium aluminum lanthanum hydrotalcite forms a dense composite char layer structure, effectively isolating heat and oxygen, thus improving the flame-retardant properties of the fireproof coating. Simultaneously, it also possesses good hydrophobic protective properties, enhancing the hydrophobic properties of the exposed hydrophobic flame-retardant fireproof coating. The modified sodium lignosulfonate effectively improves the UV resistance of the exposed hydrophobic flame-retardant fireproof coating, extending the coating's UV aging resistance life.

This disclosure relates to a liquid sealing system for a roasting machine. The system includes: a sealing groove, a sealing plate, and a sealing plate flipping assembly; the sealing groove is disposed on the side wall of the roasting machine's bellows and / or furnace hood, for holding a sealing liquid; the sealing plate is disposed on the trolley of the roasting machine, for immersing itself in the sealing liquid when the sealing plate enters the sealing groove, thereby sealing the roasting machine's bellows and / or furnace hood; the sealing plate flipping assembly includes an arc-shaped guide rail, for causing the sealing plate to flip and bend along the arc-shaped guide rail when the sealing plate enters or leaves the sealing groove, and for allowing the sealing plate to enter or leave the sealing groove after flipping and bending. The liquid sealing system for a roasting machine according to embodiments of this disclosure can reduce air leakage rate, improve heat utilization efficiency and fan utilization efficiency, and the sealing liquid can be an ordinary liquid, does not need to be magnetic, and the sealing effect is not affected by high temperatures. It can also simplify the construction of the sealing system and the trolley, reducing costs.
