Abstract

The invention provides a decorative black-white film and a preparation method thereof. The decorative black-white film is formed by compounding a black film and a white film; the black film is prepared from polyether polyol I, diisocyanate I, borate, a silane coupling agent I, carbon black and a chain extender I; the white film is prepared from polyether polyol II, diisocyanate II, alkoxy aluminum, a silane coupling agent II, a white filler and a chain extender II; the black film is attached to a base cloth, so that the shading effect is achieved; and the white film can meet the attractive requirement of a shading curtain. The decorative black and white film is prepared through a composite film blow molding unit, compounding of two layers is achieved in a die head, the attaching procedureis omitted, the preparation process is convenient and rapid, the shading rate of the obtained decorative black and white film reaches 100%, and the decorative black and white film has excellent mechanical performance and aging resistance, and can fully meet the application requirements of the shading film in decorative materials such as the shading curtain.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a black and white film for decoration and a preparation method thereof. Background technique [0002] Roller blinds or fabric curtains with shading effect are very important decorative materials. Conventional shading roller blinds or fabric curtains achieve the shading effect by coating the shading coating multiple times, but the coating process will generate more exhaust gas And waste water, bring environmental protection pressure, and the coating process is complicated, so that the production energy consumption is increased, and the cost is too high. Therefore, replacing the light-shielding coating with a light-shielding film has gradually become the mainstream trend in the production process of the light-shielding curtain. [0003] The base material of the shading film is a polymer film, including polyolefin film or polyurethane film. Among them, thermo...
