Embodiment 1

[0037]Selection of PET base film: Select Melinex406, an optical-grade PET base film from DuPont Company, with a thickness of 23 microns. Both sides of the base film are pre-coated, which can improve the composite strength and the adhesion of the scratch-resistant layer.

[0038] Preparation of carbon black slurry: Weigh 4 parts of carbon black with a particle size of 15 nanometers, 2.8 parts of dispersant and 93.2 parts of ethyl acetate, first mix and stir the dispersant and solvent in the ball mill pre-mixing tank for 20 minutes, and then pass into Grind in the grinding chamber of a ball mill, and gradually add carbon black, and make a carbon black slurry after 10 hours of grinding.

[0039] Preparation of blue pigment slurry: Weigh 10 parts of blue pigment, 10 parts of dispersant and 80 parts of methyl ethyl ketone, mix and stir the dispersant and solvent in the ball mill pre-mixing tank for 20 minutes, and then pass it into the grinding chamber of the ball mill Grinding and...

Embodiment 2

[0044] Embodiment 2 is all the same with the used PET film and slurry of embodiment 1, and the difference is that the ratio of carbon black, blue pigment and red pigment in the composite functional coating is not the same, specifically as follows:

[0045] Preparation of Composite Functional Coating B: Weigh 9.73 parts, 1.37 parts and 1.73 parts of each of the carbon black slurry, blue pigment slurry and red pigment slurry prepared above, and the composite adhesive Cytec one-component acrylic pressure-sensitive adhesive 265 (30% solid content) 44.35 parts, ethyl acetate 31.69 parts, butanone 4.27 parts, diacetone alcohol 6.86 parts. First add the solvent to the mixing tank, then add the pigment slurry, stir for 20 minutes, and finally add the composite glue gradually and stir 60 parts to make a composite functional coating.

[0046] Preparation of low-permeability heat-insulating film: apply the above-mentioned composite functional coating on either side of the first base film...

Abstract

The invention provides a low-permeability thermal-insulation film with high weatherability and high definition. The cross section of the low-permeability thermal insulation film with high weatherability and high definition possesses a base film-low permeability thermal insulation coating layer-base film sandwich layer structure; the low permeability thermal insulation coating layer is formed via coating of a composite functional coating; the composite functional coating at least comprises a pigment slurry, a composite adhesive, and a solvent; the pigment slurry at least comprises a carbon black slurry, a blue pigment slurry, and a red pigment slurry; the composite adhesive is preferably selected from a one-component or a two-component acrylate composite adhesive, the peeling strength of the composite adhesive with the base film is larger than 800g / inch, and preferable matching of the composite adhesive with the pigment slurry is achieved. The low-permeability thermal-insulation film possesses both high weatherability and high definition, the optical performance remains basically unchanged after irradiation under 100mW / cm2 ultraviolet light for 10Hr, the haze is lower than 0.2%, and optical level definition is achieved.

Description

technical field [0001] The invention relates to a composite heat-insulating film, in particular to a low-permeability heat-insulation film with high weather resistance and high definition, and a preparation method of the low-permeability heat-insulation film, which belongs to the technical field of composite film processing. Background technique [0002] Heat insulation film, also known as sunlight film, is mainly used to adjust the ultraviolet light, visible light and infrared energy in sunlight. Visible light mainly adjusts the visible light entering the room and car through dye film, metal film, pigment film or a combination of the three. Proportions for increased comfort and partial insulation. Dye film is relatively easy to match various composite glues or resins, which can ensure the high definition of the film, but its weather resistance is poor, and basically has no infrared blocking effect. The metal aluminum film not only has a short service life, but also has ser...
