Preparation method of environment-friendly light guide panel ink

Abstract

The invention relates to a preparation method of an environment-friendly light guide panel ink, which comprises the following steps: charging, heating, stirring to react, cooling for conversion, kneading and discharging. The preparation method is characterized by comprising the following steps: adding an acrylic resin, a non-halogen material and a non-benzene solvent in a certain mass ratio, heating, starting stirring, vacuumizing, reacting for some time, cooling, transferring the reaction product into a kneader, kneading and discharging. The environment-friendly light guide panel ink is a product prepared by adding the resin into the nano light guide powder, dispersing and grinding. The ink is an ideal material for printing LED (light-emitting diode) liquid crystal backlight modules, high-quality ultrathin advertising lamp casings and other backlight/light guide panels. The coating-type nano light guide powder is mainly used for generating refraction reflective ions in the non-transparent/semitransparent/transparent inks, and has the advantages of wear resistance, high brightness, excellent uniformity, excellent repeatability and excellent sealing property.

Description

technical field [0001] The invention relates to the field of chemicals, in particular to a preparation method of an environmentally friendly light guide plate ink. Background technique [0002] The relationship between human beings and chemical industry is very close. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing, and transportation to spiritual life such as culture, art, and entertainment, chemical products are required to serve them. . Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. [0003] The light guide plate is made of optical-grade acrylic / PC board, and then high-tech materials with high reflectivity and non-absorbing light are used to print light guide points on the bottom surface of the optical-grade acrylic board with UV screen printing...

Problems solved by technology

[0004] Most of the light guide inks currently on the market contain certain halogens and benzene-based solvents. As we all know, halogens and benzene-based solvents are very harmful to the human body and the ecological environment, thus affecting the health of people who come into contact with them.
