Abstract

The invention discloses a heat-insulating TPU (thermoplastic polyurethane) protective film which comprises a base material layer and a rubber layer arranged at the lower part of the base material layer, wherein the base material layer is a TPU film, the upper surface of the TPU film is provided with a heat insulation coating, the heat insulation coating comprises the following components in partsby weight: 20-50 parts of a heat-insulating filler, 50-80 parts of polyurethane acrylic resin, 0.01 to 6 parts of a cross-linking agent and 0.01 to 10 parts of a metal oxide; wherein the heat-insulating filler is hollow glass beads or/and high-molecular microspheres. The TPU film provided by the invention has good mechanical property, heat resistance, heat insulation property and oil contaminationresistance, and is especially suitable for kitchen utensils and building outer windows.

Description

technical field [0001] The invention relates to a protective film, in particular to a heat-insulating TPU protective film. Background technique [0002] PVC film or PET film is widely used as a protective film in various fields of production and life. Among them, the protective film for building exterior windows and kitchens is required not only to have a certain anti-scratch and anti-abrasion effect on the materials that need to be protected, but also for building exterior windows. Due to the long-term exposure to the outdoors, it needs to resist high temperature and changeable environment, and the kitchen protective film is used in the environment of high temperature and heavy oil pollution, so there are high requirements for the anti-fouling and high temperature resistance of the protective film, and for different The protection of the shape structure requires the protective film to have strong ductility and flexibility. In addition, building exterior windows also have h...
