Problems solved by technology

[0003] When PC is applied to the surface film or functional film of electronic products, due to the interference of light, sometimes partial rainbow patterns will appear; variable rainbow patterns that appear as the angle changes are normal, but there are also constant rainbow patterns. It is due to the uneven thickness of the PC film or its upper layer that causes film interference, which will greatly affect the user experience

Embodiment Construction

[0021] In order to illustrate the embodiments of the present application or the technical solutions in the prior art more clearly, the embodiments will be briefly introduced below.

[0022] Such as figure 1 , a high-definition non-rainbow anti-scratch PC material protective film, the right side is the outside, the left side is the inside, including the upper protective layer 1, the glue layer 2, the anti-reflection layer 3, the scratch-resistant layer 4, and the PC from the outside to the inside. Film layer 5, lower glue layer 6, release glue layer 7, release layer 8, the anti-scratch layer 4 is coated with an anti-scratch coating agent, and the upper glue layer 2 and the lower glue layer 6 are all It is obtained by coating with silica gel glue; the material of the release layer 8 and the upper protective layer 1 is one of PET film and PC film;

[0023] The anti-scratch coating agent includes the components in parts by weight mentioned in the examples in Table 1.

Abstract

The invention discloses a high-definition rainbow-free scratch-proof PC material protective film. The film sequentially includes an upper protective layer, an upper glue layer, an antireflective layer, a scratch-proof layer, a PC film layer, a lower glue layer, a release glue layer and a release layer from the outside to the inside. The scratch-proof layer is formed by coating a scratch-proof coating agent. The scratch-proof coating agent includes the following raw materials, by weight, 20-30 parts of PC resin, 12-16 parts of water-borne polyurethane, 15-19 parts of waterborne acrylic resin, 3-6 parts of polymethyl methacrylate, 1.5-3 parts of polysiloxane, 0.5-2 parts of nano silicon dioxide, 1-2 parts of antioxidant, 1-3 parts of leveling agent, 0.2-3 parts of viscosity regulator and 70-100 parts of solvent. According to the defects that the PC has no scratch resistance, high transparency and uneven thickness and rainbows easily occur, the two problems are solved through even coatingand film coating, and the application value of the PC protective film is improved.

Description

technical field [0001] The invention relates to a glass film, in particular to a high-definition rainbow-free anti-scratch PC protective film and a preparation method thereof. Background technique [0002] PC film, also known as polycarbonate film, is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastic with excellent physical and mechanical properties, especially excellent impact resistance, tensile High strength, bending strength, compressive strength; small creep, stable size; good heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide temperature range It can be used for a long time at -60 ~ 120 °C; it is also a representative of high transparency film in the field of film. Due to its excellent properties, it is widely used in electronic components, electrical casings, switch panels, junction boxes and charger...
