In order to make the above objects, features and advantages of the present invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples:
a method for improving the brightness of a glass diffusion plate, comprising the following steps: step one: cutting the glass into glass substrates; step two: printing diffusion coating on the upper and lower surfaces of the glass substrate, wherein the number of the printing screen is 300, and the printing thickness is 8-10 mu m; in the second step, the diffusion coating is composed of a first ink and a second ink in a weight ratio of 1:1.
Wherein the first ink comprises: 50-60wt% of titanium dioxide, the particle diameter being 3 microns; the second ink includes: 20-25% of titanium dioxide and 15-20% of silicon dioxide. The average particle diameter of the titanium dioxide in the first ink was 3 μm.
In this example, the surface roughness Ra of the diffusion coating is 1.56-1.92 μm to give a light transmittance of 47-53% after printing. The average particle diameter of the titanium dioxide in the first ink is 5-6 microns, and the average particle diameter of the silica particles is 3 microns.
In this embodiment, the first ink may be, but not limited to, model 1203C and the second ink may be, but not limited to, model 1601. Compared with the titanium dioxide diffusion particles of small particles in 1203C, the large-particle titanium dioxide diffusion particles in 1601 ink have improved diffusion effect and shielding effect, the large-particle silicon dioxide particles in 1601 have low refractive index and lower density (silicon dioxide density is 2.2g/cm < 3 >, titanium dioxide density is 3.9-4.2g/cm < 3 >, and the silicon dioxide particles of large particles float upwards in the wet film flowing process after the diffusion coating is printed, so that the surface roughness of the coating is increased, the diffusion effect of the coating is improved, and meanwhile, the integral light transmittance of a film layer is improved, so that 1601 ink has equivalent shielding and diffusion effects compared with 1203C ink, but has higher light transmittance, and when 1601 ink is independently coated on the surface of glass, the adhesive force between the coating and the glass is reduced due to larger diffusion particle particles, the mechanical property of the diffusion particle glue of the diffusion coating is influenced, and the adhesive force between the diffusion particle particles and the glass is higher, and when the diffusion particle glue and the glass are mixed in a ratio of 1/1, the prepared diffusion coating has better optical property and mechanical property.
In summary, by changing the particle size and the component ratio of the diffusion ink, the light transmittance of the diffusion coating is improved, and meanwhile, the shielding effect and the diffusion effect of the diffusion coating are ensured, so that the purpose of improving the overall brightness of the glass diffusion plate is achieved.
Examples:
and (3) manufacturing a glass diffusion plate, wherein 1.1t of common soda lime glass is adopted as glass, 1203C+1601 mixed ink coating is printed on the two sides, the mixing ratio is 1 to 1, then an OCA optical adhesive and a DBEF optical film are sequentially attached to the surface of the upper diffusion coating, and the optical performance and the mechanical performance of the glass diffusion plate are tested by matching with a backlight module.
