Embodiment Construction

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Such as figure 1 As shown, a preparation method of 200 layers of color adhesive film is shown. It includes premixing and modifying inorganic pigments and titanium dioxide to obtain modified mixed fillers; adding the modified mixed fillers into the film material, mixing and stirring, and extruding to obtain the colored film 200 .

Abstract

The invention discloses a preparation method of a color adhesive film (200), and a color tile. The preparation method comprises the following steps: premixing and modifying an inorganic pigment and titanium dioxide to obtain a modified mixed filler; and adding the modified mixed filler into an adhesive film material, carrying out mixing and stirring, and carrying out extrusion molding to obtain the colored adhesive film 200. The colored adhesive film 200 obtained by the method can shield long-wave ultraviolet light (320-400 nm) and medium-wave ultraviolet light (280-320 nm), and ultraviolet light transmittance is less than 5%. When a solar constant is 1535 w/m<2> and the adhesive film is irradiated for 100-1000 h, the phenomena of degradation, yellowing and the like of the adhesive film are avoided.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for preparing a colored adhesive film and a colored tile. Background technique [0002] The current adhesive films used for packaging photovoltaic modules are almost all white and translucent materials. The prepared photovoltaic modules all show the color of the cell sheet or the background color of the back sheet. However, due to the need for product aesthetics, to expand the types of products, the use of colored film can change the background color of the product and increase the beauty of the product, and when the film is only used on the back layer of the chip, it can be used without affecting the light transmittance of the module. Add an appropriate background color to the component. [0003] Since photovoltaic modules require long-term exposure to sunlight to generate electricity, the packaging materials used are required to have good UV aging resistance. The current...
