Abstract

The invention relates to a building window decoration composite film with a temperature regulation function and a preparation method thereof. The building window decoration composite film comprises aheat conducting phase change micro-capsule and a film; the weight ratio of the heat conducting phase change micro-capsule to the film is (2-3):10; the heat conducting phase change micro-capsule comprises a heat conducting agent, a film forming material and a phase change material; and the film is prepared from raw materials including a solvent, a binder, heat conducting fibers and a dispersant. The preparation method comprises the following steps: S1, preparing a heat conducting phase change micro-capsule: placing a heat conducting agent and a film forming material in a reaction container, carrying out stirring until the heat conducting agent and the film forming material are completely dispersed, adding an emulsifier, carrying out high-speed shearing and emulsifying, adding a melted phasechange material, and carrying out spray drying to obtain the heat conducting phase change micro-capsule; S2, preparing a composite film; and S3, preparing a finished product. The building window decoration composite film provided by the invention has the advantages of adjustable temperature, good light change effect and no pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of functional films, in particular to a composite film for building window decoration with a temperature regulating function and a preparation method thereof. Background technique [0002] Composite film is a polymer material composed of two or more layers of films of different materials. Through the interaction of different materials in the composite film, the advantages of each layer are accumulated. The following are the functions of the composite film: water vapor barrier, prevent wet goods from drying and cool wet wipes: protect dry goods from moisture , such as baked products, powdered products; acid barrier. Prevent oxidation, such as for fat and fresh goods; carbon dioxide barrier. Prevent carbon dioxide loss in MAP packaging to achieve stable packaging gas composition plus carbonated beverages; aroma barrier to protect aroma from volatilization from the package and loss such as coffee; odor barrier...
