Embodiment 1

[0067] In the hydrolysis-resistant white reflective film provided by the invention, the proportion of layer A is 89.5% of PET slices, 10% of silicon dioxide particles, and 0.5% of epoxy fatty acid glyceride. The proportion of layer B is 71% PET chips, intrinsic viscosity 0.68dL / g, 10% rutile titanium dioxide, 10% polymethylpentene, 5% MAH grafted SEBS (grafting rate ≥ 0.5%), 2% carbonization Diimine, 1% Millad3988 (Milliken Company), 1% PEG (molecular weight: 20,000), and the stated percentages are weight percentages. The thickness of layer A accounts for 12% of the total thickness, and the thickness of layer B accounts for 88% of the total thickness. The thickness of the obtained reflective film is 188 μm, and the relevant properties are shown in Table 1.

Embodiment 2

[0069] In the hydrolysis-resistant white reflective film provided by the invention, the proportion of layer A is 89.5% of PET slices, 10% of silicon dioxide particles, and 0.5% of epoxy fatty acid glyceride. The proportion of layer B is 66% PET chips, intrinsic viscosity 0.68dL / g, 10% rutile titanium dioxide, 15% polymethylpentene, 5% MAH grafted SEBS (grafting rate ≥ 0.5%), 2% carbonization Diimine, 1% Millad3988 (Milliken Company), 1% PEG (molecular weight: 20,000), and the stated percentages are weight percentages. The thickness of layer A accounts for 12% of the total thickness, and the thickness of layer B accounts for 88% of the total thickness. The thickness of the obtained reflective film is 188 μm, and the relevant properties are shown in Table 1.

Embodiment 3

[0071] In the hydrolysis-resistant white reflective film provided by the invention, the ratio of layer A is 89% of PET slices, 10% of silicon dioxide particles, and 1% of epoxy fatty acid glyceride. The proportion of layer B is 65.5% PET chips, intrinsic viscosity 0.68dL / g, 15% rutile titanium dioxide, 10% polymethylpentene, 5% MAH grafted SEBS (grafting rate ≥ 0.5%), 2% carbonization Diimine, 1.5% Millad3988 (Milliken Company), 1% PEG (molecular weight: 20,000), and the stated percentages are weight percentages. The thickness of layer A accounts for 12% of the total thickness, and the thickness of layer B accounts for 88% of the total thickness. The thickness of the obtained reflective film is 188 μm, and the relevant properties are shown in Table 1.

Abstract

The invention relates to a hydrolysis-resistant white reflective film, more specifically, the invention relates to a hydrolysis-resistant white reflective polyester film. In order to improve the hydrolysis resistance of the existing white reflective film, the invention provides a hydrolysis-resistant white reflective polyester film and a preparation method thereof. The white reflective polyester film is an ABA three-layer structure; the A layer in the white reflective polyester film includes polyester resin, hydrolysis stabilizer and inorganic particles; the B layer in the white reflective polyester film includes polyester Resins, hydrolysis stabilizers, inorganic particles, incompatible resins, toughening resins, chain extenders, nucleating agents and dispersants. The reflectivity of the reflective film provided by the present invention is basically the same as that of the existing reflective film, and its hydrolysis resistance is very good. display device.

Description

technical field [0001] The invention relates to a hydrolysis-resistant white reflective film, more specifically, the invention relates to a hydrolysis-resistant white reflective polyester film. Background technique [0002] As the screen displays of mobile phones and TVs are developing towards large-screen displays, the demand for liquid crystal displays in the market is huge. These liquid crystal displays (LCD) provide illumination light by setting a surface light source called a backlight on the inside. to display. The backlight is mainly composed of light source, light guide plate, and backlight module. The reflective film plays an important role in gaining brightness in the entire backlight module. [0003] While the demand for display equipment is increasing sharply, people's demand for display performance is also becoming more and more diverse. Light and thin, flexible, high brightness, and wide color gamut are the mainstream. In addition, there are also requirements ...
