Description
Technical Field
The invention belongs to the technical field of functional films, and particularly relates to a hardening layer coating liquid and an anti-dazzle film.
Background
In-vehicle display screens, notebook computers, liquid crystal displays, etc., images are recognized by functional films on the surfaces, and light emitted from the internal backlight assembly of these displays can be transmitted smoothly with reduced intake, diffuse reflection occurs during external light intake, and glare is prevented, and the glossiness is reduced, so that the image quality is improved. Because the functional film is arranged on the outermost layer of the display, the surface of the display can be frequently wiped in daily use and maintenance, and the scratch of the surface is easily caused, so that the service life and the appearance are influenced.
Along with the development of technology, the resolution of the display is higher and higher, and meanwhile, the problem of picture shake is generated, and the prior art is to continuously add particles such as silicon dioxide and the like to improve the overall haze, so that the whitening of a screen occurs, and particularly under the background of a black screen, the value of the black depth is low, the taste is too low, and the visual effect is poor.

The antiglare film described above can solve the problems of transparency, flickering and blushing, however, since the large particles of the antiglare film are organic particles, the composition is acrylic resin, and the inorganic particles having no composition of silica have good abrasion resistance, it does not have good abrasion resistance. And the organic particles have swelling effect, and the organic large particles can absorb a certain proportion of solvent after being placed for a long time, so that the film surface is deteriorated during coating, thereby influencing the production yield and causing great loss.

Further, the refractive index of the low refractive index hardening liquid is in the range of 1.45 to 1.49, and the refractive index of the high refractive index hardening liquid is in the range of 1.60 to 1.65.
Further, the organic particles in the hardening liquid are acrylic resin organic particles, and the inorganic particles are silica inorganic particles.
Further, in the hardening liquid, the particle size of the acrylic resin organic particles is 0.5-3 μm, and the refractive index is 1.45-1.51; the particle diameter of the silica inorganic particles is 1-5 mu m, and the refractive index is 1.45-1.51.
Further, the particle size of the organic particles is 0.5 to 2.0. Mu.m, and the particle size of the inorganic particles is 2 to 3. Mu.m.
Further, the low refractive index hardening liquid comprises a six-functional polyurethane acrylic resin oligomer, a three-functional acrylate monomer and a two-functional acrylate monomer; the high refractive index hardening liquid comprises a hexafunctional polyurethane acrylic resin oligomer, a tetrafunctional acrylic monomer and zirconia nano particles with the particle size of 20-50 nm.
The coating liquid for the hardening layer forms an anti-dazzle film hardening layer after solidification, has high light transmittance and high wear resistance, and can control the 60-degree specular glossiness to be 50-70 degrees under the condition of 25+/-2% of haze.
The invention adjusts the refractive index by adding the hardening liquid proportion of two different refractive indexes, preferably adjusts the refractive index to be between 1.45 and 1.55, forms internal fog by the refractive index difference with different particles, has wide application range and has small limitation on the particles.
According to the invention, two types of particles are added into the hardening liquid with a well-regulated proportion, wherein small particles are organic particles, the average particle size is 0.5-3.0 mu m, the refractive index is 1.45-1.51, the particle size is preferably 0.5-2.0 mu m in consideration of the swelling effect of the organic particles, so that the whole particles can be buried in the hardening layer, the large particles are inorganic particles, the average particle size is 1-5 mu m, the refractive index is 1.45-1.51, the particle size is preferably 2-3 mu m, and the coating thickness of the hardening liquid is 4-8 mu m.
Further, the invention provides a hardening layer coating liquid, which comprises 20-45% of low refractive index hardening liquid, 5-25% of high refractive index hardening liquid, 1-5% of organic particles, 21-54% of inorganic particle ball milling liquid and 10-17% of butanone. The inorganic particle ball milling liquid contains 15% of silica inorganic particles
The inorganic particle ball milling liquid comprises silica inorganic particles, propylene glycol methyl ether and butanone; the silica inorganic particles are dispersed in propylene glycol methyl ether and butanone.
The adding ratio of the high refractive index hardening liquid to the low refractive index hardening liquid is 1:1-1:5.
Further, the coating liquid for the hardening layer comprises 25% -45% of hardening liquid with low refractive index, 11% -25% of hardening liquid with high refractive index, 2% -5% of organic particles, 21% -35% of ball milling liquid for inorganic particles and 10% -17% of butanone.

The average particle diameter of the inorganic particles after ball milling is 1-5 mu m.
Because the inorganic particles of silicon dioxide are heavier, do not have better suspension property and can not float on the hardening layer effectively, the silicon dioxide is dissolved in propylene glycol methyl ether and butanone, ball milling is carried out to form silicon dioxide ball milling liquid with the solid content of 15%, different particle sizes can be achieved through the rotating speed of the ball mill and the ball milling time, meanwhile, after the inorganic particles are destroyed after ball milling, the inorganic particles are light in mass and are easy to suspend in a solvent, after high-temperature baking, because butanone is a low-boiling-point solvent, butanone can be evaporated from the coating liquid preferentially under the high-temperature condition, meanwhile, the silicon dioxide particles can be brought to the uppermost layer of the hardening film, and finally, after ultraviolet curing, the anti-dazzle film with high wear resistance is formed.
The solid content of the hardening layer coating liquid is 25-40%, and the percentage content is weight percentage.
Further, the high refractive index hardening liquid is produced by the chemical industry of barren, japan, and the low refractive index hardening liquid is produced by the material technology limited company of kenmeite, taiwan.
The invention also provides an anti-dazzle film which comprises a base material and a hardening layer, wherein the hardening layer is formed by curing the hardening layer coating liquid.
The substrate is a transparent base film. The transparent base film used in the present invention is not particularly limited, and examples thereof include triacetyl cellulose film (TAC), polyethylene terephthalate film (PET), and polycarbonate film (PC).
Further, the thickness of the base material is 50-250 μm, and the thickness of the hardening layer is 4-8 μm.

The preparation method and process parameters of the hard coat film were the same as in example 1.
The particle size of the organic particles in the hardening liquid in comparative example 1 was too large.

The preparation method and process parameters of the hard coat film were the same as in example 1.

Comparative example 4
The comparative example was different from example 5 in that the addition amount of the inorganic particle ball-milling liquid was 0, and each component and parts by weight thereof are shown in table 2.
The preparation method and process parameters of the hard coat film were the same as in example 1.
TABLE 2 partial raw materials and contents of the coating liquids for the hardening layer provided in comparative examples 1 to 4
TABLE 3 test results of Performance of the cured layers formed from the cured layer coating liquids provided in examples 1 to 6 and comparative examples 1 to 4
TABLE 4 test results of Performance of cured layers formed from the cured layer coating liquids provided in examples 1 to 6 and comparative examples 1 to 4
The experimental data in the table show that the hard coating films in the embodiments 1, 2, 3 and 5 of the invention have good comprehensive performance, good transparency (light transmittance), low flash point, good wear resistance and no whitening problem, and particularly after wear resistance test, the anti-dazzle film is subjected to black acrylic plate sticking treatment and does not whiten. In example 4, the coating thickness was reduced, which resulted in an excessive high protrusion height of the upper inorganic particles, a poor flash point effect, and a weak abrasion resistance, and the coated black acrylic plate was slightly whitened after abrasion resistance. In example 6, the addition ratio of the high refractive index hardening liquid and the organic particles was reduced, so that the refractive index of the neutralized hardening liquid was relatively close to that of the organic particles, and the refractive index difference was not effectively formed, so that the internal haze was insufficient, the antiglare film was not penetrated by external light, the black coating test was whitish, and the flash point effect was poor due to the large particle size of the inorganic particles.
In comparative example 1, since the organic particles having a large particle diameter were replaced, the particle diameter was too large to protrude from the surface of the cured layer together with the inorganic particles under the same experimental conditions as in example 1, and the sense of particle was too strong, thereby affecting the flash point performance. In comparative examples 2 and 3, lacking the high refractive index hardening liquid and the organic particles, the coating liquid cannot form a refractive index difference, cannot form an internal fog, cannot penetrate the antiglare film due to external light, and is diffusely reflected, and the black acrylic plate is whitened by test, and the flash point effect is poor due to the large particle size of the inorganic particles. In comparative example 4, since no inorganic particles were added, the full-line haze formed was basically internal haze, and since the external light entirely penetrated the antiglare film, specular reflection occurred, and the 60 ° specular gloss was too high, and eyes were liable to shake (i.e., as if it were a mirror).
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. All equivalent changes and modifications made in accordance with the present invention are intended to be covered by the scope of the appended claims.
