Embodiment 1

[0044] Step 1, preparing flower spherical particles.

[0045] The curd-shaped particles of the present embodiment are curd-shaped nickel oxide microspheres, which are made of macrocyclic polyamine (hexamethyl-1, 4, 8, 11-tetraazacyclo 14-4, 11-diene) using methanol, ethanol Diamine, hydrobromic acid, and acetone are raw materials, which are synthesized by chemical methods. The specific preparation method is as follows:

[0046] ① Weigh 5.0g of macrocyclic polyamine and dissolve it in 30mL of water, add 10g of basic nickel carbonate, and heat the mixture in a water bath for 30min;

[0047] 2. filter out unreacted basic nickel carbonate, and the obtained macrocyclic polyamine-nickel complex filtrate is standby;

[0048] ③Take 27mL of macrocyclic polyamine-nickel complex filtrate, dilute it with 13mL of twice distilled water, put it into a 50mL stainless steel kettle lined with polytetrafluoroethylene, put it in a temperature-programmed furnace, and react at 180°C for 24h;

Embodiment 2

[0062] With other conditions unchanged, the calcination temperature in step 5 of preparing the flower-shaped nickel oxide microspheres was increased to 6h, and the average particle diameter of the flower-shaped nickel oxide microspheres obtained was 4 μm, the height of the petals was 0.3 μm, and the width of the internal reticular voids was 0.25 μm, and the thickness of the anti-glare coating is 4.7 μm.

Embodiment 3

[0066] Other conditions remain the same, the calcination temperature in step 5 of the preparation of flower-shaped nickel oxide microspheres is increased to 8h, and the average particle diameter of flower-shaped nickel oxide microspheres obtained is 7 μm, the height of petals is 0.61 μm, and the width of internal reticular voids is 0.3 μm, and the thickness of the anti-glare coating is 7.8 μm.

Abstract

The invention provides an anti-dazzling film, which comprises a transparent substrate and an anti-dazzling coating layer which is arranged on at least one surface of the substrate. The anti-dazzling coating layer comprises resin adhesive and particles scattered in the resin adhesive. The surface of the anti-dazzling coating layer is provided with a concave and convex structure. The anti-dazzling film is characterized in that each particle is a ball-flower-shaped particle and comprises an internal part and a ball body which is of a reticular void structure on the surface, the external part of the ball body is of a petal-shaped structure, and the petal-shaped structure consists of a plurality of petals which integrally grow on the surface of the ball body and stretch outwards. The invention additionally discloses a production method of the anti-dazzling film. The anti-dazzling film provided by the invention has the advantages that the light transmittance is increased because of the reticular void structures of the ball-flower-shaped particles, the resin adhesive can seep into the voids and the anti-dazzling film has higher hardness and excellent wear and scratching resistance performance after the resin adhesive is solidified; and the petal-shaped structures of the ball-flower-shaped particles enable the concave and convex structure to be formed on the surface of the anti-dazzling film and therefore the anti-dazzling film has an anti-dazzling performance.

Description

technical field [0001] The present invention relates to an anti-glare film and a manufacturing method thereof, a polarizing plate using the anti-glare film and a display device thereof. Background technique [0002] The LCD panel itself does not emit light, and its brightness comes from the backlight module, but it does not mean that the LCD panel has no effect on the brightness and clarity of the display. On the contrary, in order to achieve a better image display effect, usually the display The polarizer on the surface is specially treated to reduce the influence of internal light and external light sources to improve image recognition. A commonly used technical means is to install an anti-glare film on the viewing surface of the polarizing plate to reduce the reflected light caused by external turbulent light, so as to achieve a better viewing effect. Anti-glare film is an anti-glare coating formed on one or both surfaces of a transparent substrate, and some particles wi...
