Embodiment 1

[0071] The anti-scratch coated reflective sheet provided by the present invention includes a reflective sheet and a coating layer positioned on the surface of the reflective sheet, and the main layer of the reflective sheet includes TiO with a mass fraction of 5%. 2 , the average particle size of the particles is 0.2 μm, and the mass fraction is 10% polypropylene resin (produced by Borealis, the product model is WF420HMS), 85% polyester resin (PET film grade chips produced by China Yizheng Chemical Fiber Co., Ltd., commodity The grade is FG620); the auxiliary layer of the reflection sheet includes an antistatic agent (plastic antistatic agent 006 produced by Zhongteng Chemical Co., Ltd.) with a mass fraction of 8%, and a hindered amine light stabilizer poly﹛[ 6-[(1,1,3,3-tetramethylbutyl)-amino]]1,3,5-triazine-2,4-bis[(2,2,6,6-tetramethyl- Piperidinyl)-imino]-1,6-hexadiene-[(2,2,6,6-tetramethyl-4-piperidinyl)-imino]﹜ (trade name is CH944, manufactured by BASF Produced by the ...

Embodiment 2

[0078] A coated reflective sheet was fabricated in the same manner as in Example 1, except that the average particle diameter of the PET particles in the coating layer was replaced with particles of 20 μm as in the reflective sheet provided in Example 1. The evaluation results are summarized in Table 1.

Embodiment 3

[0080] The reflective sheet provided in Example 1, except that the average particle diameter of the PET particles in the coating layer is replaced by particles of 25 μm, and the TiO in the main layer of the reflective sheet 2 A coated reflective sheet was produced in the same manner as in Example 1 except that the average particle diameter of the particles was 0.4 μm. The evaluation results are summarized in Table 1.

Abstract

The invention relates to the field of polyester films, and concretely relates to an anti-scratch coated reflective sheet and a preparation method thereof to solve the problems that a conventional reflective sheet is liable to scratch a light guide plate and shadows are liable to be generated. The anti-scratch coated reflective sheet comprises a reflective sheet and a coating layer arranged on the surface of the reflective sheet. The coating layer comprises an adhesive and organic particles, and the organic particles are bonded to the surface of the reflective sheet through the adhesive. Raw materials of the coating layer are configured to be coating liquid, the coating liquid includes liquid and organic particles, and the liquid includes the adhesive. The weight of the organic particles accounts for 0.5%-15% of the weight of the liquid. The average particle size of the organic particles is 5[mu]m-40[mu]m. The anti-scratch coated reflective sheet can well prevent a light guide plate from being scratched, can well prevent adsorption between the light guide plate and the reflective sheet, and will not generate shadows.

Description

technical field [0001] The invention relates to the field of polyester films, in particular to an anti-scratch coating reflection sheet with excellent anti-scratch performance and a preparation method thereof. Background technique [0002] Liquid crystal display devices include a backlight system in which a light source is placed on the back of a backlight unit and an edge light system in which a light source is placed on a side of the backlight unit. As the overall thickness of LCD backlight modules decreases, more and more direct-type models and side-type models with a short OD (abbreviation for Optical Distance, referring to the distance between the light source and the diffuser plate) are selected. In the side-entry type, it is necessary to apply a light guide plate to convert the light from a point light source to a surface light source, but ordinary uncoated reflectors will be adsorbed on the light guide plate, causing shadows and other undesirable phenomena. Therefor...
