    Abstract: An endothermic fireproof cladding material for electric cables, a cross-sectional structure of which is a two-layer or three-layer laminated composite structure in an integrated structure by coating, and one of the laminated structures has a fireproof fiber mesh cloth having a thickness of 0.03 mm to 0.24 mm as a coating and coating substrate. The fireproof fiber mesh cloth is selected from one of a glass fiber, a carbon fiber, a polyacrylonitrile (PAN) oxidized fiber, a ceramic fiber, a water-soluble alkaline earth fiber and an aromatic polyamide fiber.

    Abstract: A method for preparing a polyester modified material from a recycled release film includes continuously performing the following steps at an elevated temperature: subjecting the recycled release film to a first melting treatment to form a low-viscosity polyester; subjecting the low-viscosity polyester to a polymerization treatment to form a high-viscosity polyester, wherein a viscosity of the high-viscosity polyester is greater than a viscosity of the low-viscosity polyester; and adding a modifier to the high-viscosity polyester to perform a second melting treatment to form the polyester modified material.
