Degreasing agent for glass light guide plates

Abstract

The invention provides a degreasing agent for glass light guide plates. The degreasing agent comprises, by weight, 35-50% of glycol ether solvent, 30-50% of acid ester solvent, 5-20% of detergents, 0.1-3% of demulsifiers, 0.1-3% of defoaming agents and 0.005-0.01% of chelating agents. The glycol ether solvent is one of propylene glycol monomethyl ether, dipropylene glycol methyl ether and dipropylene glycol mono butyl ether; the acid ester solvent is one of dimethyl succinate, butyl acetate and dimethyl glutarate. The degreasing agent for the glass light guide plates has the advantages that the degreasing agent is efficient in grease removal capacity, only 3% of degreasing agent needs to be added into each glass light guide plate, and accordingly 95% of grease attached to the surfaces of the glass light guide plates can be removed.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a degreasing agent for glass light guide plates. Background technique [0002] The light guide plate is one of the key parts in the backlight module. The composition of the light guide plate is to use optical-grade acrylic / PC sheet, and then use high-tech materials with high reflectivity and non-absorbing light to use laser light on the bottom of the optical-grade acrylic sheet. Engraving, V-shaped cross grid engraving, and UV screen printing technology to print light guide points. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the lig...

AI Technical Summary

Problems solved by technology

[0003] In the current glass light guide plate printing ink manufacturing light guide point technology, due to the residual oil on the surface of the glass light guide plate, after the ink is cured on the surface of the glass light guide plate, there is a common problem that the light guide point is easy to fall off on the glass light guide plate. That is, the adhesion between the ink and the glass light guide plate is not enough, which affects the quality of the glass light guide plate

[0004] Existing degreasing agent composition mostly is the solvent of surfactant system, as the patent document " non-phosphorus degreasing agent " of publication number CN101314855A discloses a kind of non-phosphorus degreasing agent, it is made of surfactant, self-defoaming emulsifier , sodium hydroxide, sodium citrate, sodium carbonate, sodium silicate nonahydrate, and water. The phosphorus-free degreasing agent has no strict requirements on raw materials and low operating temperature, but its degreasing effect is not obvious, and it is used as a formula of surfactant system , its viscosity is generally large, and it needs to be stirred by a machine to make it fully mixed in water, which brings great inconvenience to the operation.
