Embodiment 1

[0013] In this embodiment, a kind of ink for printing patterns on the light guide film is proposed, which includes the following components in weight percentage:

[0014] 10% glycerin, 1% surfactant, 8% polyethylene glycol, 0.1% nano-titanium dioxide particles, and the balance is deionized water.

[0015] Wherein, the nano-titanium dioxide has a diameter of 30-50 nanometers.

[0016] A method for preparing the aforementioned ink, comprising the steps of adding deionized water, glycerin, polyethylene glycol, and nano-titanium dioxide particles into a container in sequence at room temperature, stirring at a speed of 500 rpm for more than 60 minutes until dissolved; using a pore size of less than 0.25 After filtering with a filter membrane of μm, the finished ink is obtained.

Embodiment 2

[0018] In this embodiment, a kind of ink for printing patterns on the light guide film is proposed, which includes the following components in weight percentage:

[0019] 10% of glycerin, 1% of surfactant, 8% of polyethylene glycol, 0.2% of nano-titanium dioxide particles, 0.25% of antioxidant, 0.1% of pH regulator, and the balance is deionized water.

[0020] Wherein, the nano-titanium dioxide has a diameter of 30-50 nanometers.

[0021] A method for preparing the aforementioned ink, comprising the steps of adding deionized water, glycerin, polyethylene glycol, and nano-titanium dioxide particles into a container in sequence at room temperature, stirring at a speed of 500 rpm for more than 60 minutes until dissolved, and then adding surface active The agent, antioxidant and pH regulator continue to be stirred until dissolved; after filtering with a filter membrane with a pore size less than 0.25 μm, the finished ink is obtained.

Embodiment 3

[0023] In this embodiment, a kind of ink for printing patterns on the light guide film is proposed, which includes the following components in weight percentage:

[0024] 10% glycerin, 1% surfactant, 3% diethylene glycol, 5% polyethylene glycol, 0.3% nano-titanium dioxide particles, 0.25% antioxidant, 0.1% pH regulator, and the balance is deionized water.

[0025] Wherein, the nano-titanium dioxide has a diameter of 30-50 nanometers.

Abstract

The invention provides ink for printing patterns on a light guide film, the ink comprises the following components in percentage by weight: 10-15% of glycerol, 1-2% of a surfactant, 8-15% of an alcohol solvent, 0.1-0.5% of nano-scale titanium oxide particles and the balance of deionized water, the alcohol solvent comprises one or two of diethylene glycol and polyethylene glycol, and the nano-scale titanium oxide particles comprise one or two of diethylene glycol and polyethylene glycol. The nanoscale titanium oxide particles are nanometer titanium dioxide, and the diameter of the nanoscale titanium oxide particles is smaller than 50 nanometers. The preparation method of the ink provided by the invention is simple and stable in process, low in cost and suitable for batch production.

Description

technical field [0001] The present application relates to the technical field of ink production for printing patterns, and in particular, relates to inks for printing invisible patterns on polycarbonate (Polycarbonate) light guide films. Background technique [0002] Products with atmosphere glass can present various customized patterns under the illumination of light sources to heighten the atmosphere, and have begun to be widely used in various vehicles and buildings such as automobiles. [0003] Atmospheric glass windows currently on the market are usually printed on glass with luminous ink, laminated glass is synthesized through film, and then light sources are set on the edge to light up. The pattern of such products cannot be invisible after the light is off, and due to the limitation of luminescent ink printing, it can only display relatively simple patterns, and the production cost is high and the process is complicated.
