Description
Technical Field
The invention belongs to the technical field of polyester films, and particularly relates to a preparation method of a coating type reflecting film.
Background
The reflective film is one of the most important optical films widely applied to backlight modules of liquid crystal displays, and has the main effects of emitting light emitted by a light source to the light emitting direction of the backlight module, improving the light utilization rate, reducing the light loss, and achieving the purposes of improving the brightness of the backlight module and reducing the power consumption. Dividing the backlight module into a side-in type backlight module and a direct type backlight module according to the arrangement mode of the light sources; in the side-entry backlight module, the light guide plate is required to be applied, the point light source is converted into a surface light source, and an uncoated common reflecting film can be adsorbed on the light guide plate at the beginning of design, so that adverse phenomena such as dark shadows and the like are generated. Therefore, researchers begin to coat a layer of substance on the surface of the reflecting film to avoid the problem of adsorption, however, the use of the coating particles is quite remarkable, if the coating particles are too hard, the light guide plate can be scratched in the assembly process of the backlight module, so that the lighted backlight module has dot-shaped and linear bright spot phenomena, which are never allowed to appear for the backlight module; moreover, the bad phenomenon also becomes serious in the process of transporting the backlight module finished product from an assembly factory to a display complete machine assembly factory along with the transportation of the backlight module finished product; the coating particles are too soft, and under the action of gravity of the light guide plate and the action force of the buckle fixing position in the assembly process, the local white spot phenomenon, namely the top white defect known in the backlight industry, occurs after the backlight is lightened. Therefore, the application of the coating type reflecting film in the side-entry backlight module has various requirements of scratch resistance, adsorption resistance and top white resistance, and the factors such as the maintenance or improvement of the brightness of the coating type reflecting film after application and the avoidance of film surface abnormality caused by particle sedimentation in the coating process are all factors to be considered in the production process of the coating type reflecting film.
At present, all large optical film manufacturers develop coating type optical films by twisting the brains; the core technology of the anti-scratch optical reflection film is that flexible particles and non-flexible particles are coated on the surface of the reflection film, meanwhile, the flexible particles are regulated to be large in particle size, and the non-flexible particles are regulated to be small in particle size, so that the anti-scratch and anti-top-white purposes are simultaneously met.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a preparation method of a coating type reflecting film, and the prepared reflecting film has excellent scratch resistance and top white resistance effects while ensuring anti-adsorption.
In order to achieve the above purpose, the invention is realized by adopting the following technical scheme:
a method for preparing a coated reflective film, comprising the steps of:
(1) Preparation of coated particles:
dispersing inorganic particles into deionized water with the weight being 4-5 times of that of the inorganic particles, then adding cyclohexane, n-butanol and glyceryl stearate, and stirring to obtain inverse microemulsion; in the reverse microemulsion, the addition amount of cyclohexane, n-butanol and glyceryl stearate is that 200-250 mL of cyclohexane, 100mL of n-butanol and 10-12 g of glyceryl stearate are added into every 100g of dispersion liquid of inorganic particles;
adding styrene monomer and initiator into the reverse microemulsion, then carrying out reflux reaction for 1-4 h at the temperature of 60-100 ℃, filtering after cooling, washing the precipitate with deionized water for 2-3 times, and then drying under vacuum condition to obtain the coated particles;
the coating particles comprise large-particle-size coating particles and small-particle-size coating particles, wherein the particle size of the large-particle-size coating particles is 15-20 mu m, and the particle size of the small-particle-size coating particles is 3-8 mu m;
(2) Preparation of coated reflective film
Mixing and stirring the coating particles, the resin glue and the organic solvent in a liquid distribution cylinder, wherein the speed of a dispersion disc is 800-1000 r/min, the stirring time is 15-30 min, then coating the coating liquid on the surface of the reflecting film through an anilox roller, and drying the surface of the reflecting film through an oven at 100-120 ℃ to harden the coating liquid to form a coating layer, thus obtaining the coated reflecting film.
In the invention, resin glue containing coating particles is coated on a reflecting film body, wherein the coating particles are formed by taking rigid and hard inorganic particles as cores and polystyrene resin as a coating layer; the reflective film with the coating layer can effectively prevent the adsorption between the reflective film and the light guide plate, thereby preventing the poor phenomenon of shadow caused by the adsorption of the reflective film; in addition, the polystyrene resin coated with the coated particles can well avoid scratching the light guide plate, and avoid the phenomena of scratching, scratching and the like of the light guide plate in the assembly process of the backlight module; more importantly, the core of the rigid hard inorganic particles of the coating particles can not excessively deform the coating particles of the coating layer when the reflecting film of the light guide plate is extruded, namely, the phenomenon of top white is effectively prevented.
In the invention, the inorganic particles are Al 2 O 3 Particles, siO 2 Particles, tiO 2 Particles, baSO 4 Particle, caCO 3 One or a combination of at least two of the particles;
the particle diameter of the inorganic particles is 1-15 mu m.
And coating polystyrene resin on the surfaces of the inorganic particles to form a core-shell structure with rigid inorganic particles inside and polystyrene resin outside.
According to the present invention, the amount of the coating particles used in the present invention can be selected in a wide range, however, the excessive amount of the coating particles is disadvantageous in that it causes an increase in production cost, and the excessive coating particles are deposited on the reflective film body, shielding the reflected light to cause a decrease in reflectivity; the coating particles are excessively small in addition amount, so that the number of the protruding particles on the coating is reduced, and when the light guide plate is extruded to the reflecting film, the phenomenon of white spots caused by local adsorption is easy to occur; in the invention, the coating particles account for 3-15% of the weight of the coating layer, wherein the mass ratio of the large-particle-size coating particles to the small-particle-size coating particles is 1: (3.8-5.5). The layering high-low protruding configuration is generated by matching the large-grain-size coating particles and the small-grain-size coating particles, namely, the protruding height of the large-grain-size coating particles is high, and the protruding height of the small-grain-size coating particles is low, so that the aims of resisting adsorption and resisting top white can be fulfilled by the small total number of the coating particles.
Further, in the present invention, the coating particles account for 5 to 10% of the weight of the coating layer, wherein the mass ratio of the large-particle-diameter coating particles to the small-particle-diameter coating particles is 1: (4.5-5).
In the invention, the vacuum condition in the step (2) is that the vacuum degree is 0.35-0.45 Mpa, and the drying temperature is 40-45 ℃.
In the invention, the resin glue is one or a combination of acrylic resin glue and polyurethane resin glue.
Further, in the present invention, the thickness of the coating layer is 10 to 20 μm; the thickness of the coating layer refers to the thickness of the dry film of the coating layer, and the thickness of the coating layer refers to the thickness of the coating film formed by curing the resin glue. When the thickness of the coating is too thin, a large amount of coating particles are easily exposed, and the problem of particle falling is easily caused; the thickness of the coating is too thick, so that the loss of light is easily increased, and the production cost is increased.
Compared with the prior art, the invention has the following technical effects:
the coating type reflecting film prepared by the invention avoids the abnormal condition of the film surface caused by uneven dispersion of the existing flexible particles and inflexible particles in the coating liquid by arranging the coating particles with different particle diameters and similar properties in the coating liquid;
the coating particles provided by the invention comprise a structure with the rigid inorganic particles as cores and the polystyrene resin as the coating layer, and the rigid inorganic particles in the inner layer provide effective support and prevent the problem of extrusion deformation, so that the scratch problem of the traditional coating type reflecting film on the light guide plate is effectively prevented; the polystyrene resin is used as a coating layer, is softer in material quality, and can effectively avoid scratching the light guide plate.
The coating type reflecting film provided by the invention has very good adaptability to various light guide plate materials in the prior art, such as a PMMA light guide plate with harder materials and an MS light guide plate with softer materials.
