Abstract
The invention provides an environment-friendly optical glass deinking agent. The deinking agent is a water solution containing alkali compounds, inorganic auxiliary agents, organic auxiliary agents and high-flash-point organic solvents. The alkali compounds are selected from one or two of hydroxide and alkali metal salt of alcohol. The inorganic auxiliary agents are selected from one or more of carbonate, silicate and borate of metal. The organic auxiliary agents are amine compounds. The high-flash-point organic solvents are selected from one or two of alcohol ether compounds, polyhydric alcohols and derivative of the polyhydric alcohols. The glass deinking agent is mainly used for removing screen printing ink on sheet glass, touch screens and other glass; the deinking agent has very good removal effects on single-layer black ink, multi-layer white ink, light blocking printing ink, UV printing ink, shielding printing ink and the like for the printing ink to be removed.
Description
Technical field
The present invention relates to a kind of chemical technology field, relate to a kind of environment-friendly type opticglass deinking agent particularly.
Background technology
Opticglass ink for screen printing is one important procedure in glass processing, and the Logo at the edge of the glass such as handset touch panel, tablet personal computer display screen, button and decorative pattern are all by silk-screen operation, adopts the solidification measure of ink and is formed.Ink has the feature such as stable chemical nature, anti-oxidant, anticorrosive strong, high abrasion resistance by the rete that hot setting is formed, and is widely used in the fields such as electronic product, medical facilities, research equipment.
But, usually need ink to remove in following several situation: 1), ink silk screen printing is bad, in order to cost-saving, silk-screen again of need doing over again of reducing the loss; 2), in process of production, ink is for covering the part on workpiece, and non-shaded portions will carry out other operations (such as metallizing rete, etching etc.), the ink covered will be removed when completing operation; 3), through life-time service, the ink on workpiece is damaged or aging, when needing to remove again ink for screen printing.Due to the strong adhesion of ink, will remove completely at short notice and not affect ground workpiece is also difficult problem place in industrial application.
Existing de-inking method mainly contains 1), Halogen, to remove containing benzene solvent: it is long that this method removes the time, and solvent evaporates amount is large, has very large detrimentally affect to the health of environment and operator; 2), soda boiling removes: this method energy consumption is high, and higher to the requirement of equipment, eliminates gradually; 3), common deinking agent removes: this deinking agent uses more now, ubiquitous problem is inflammable, needs to be heated to 80 DEG C ~ 90 DEG C during use, effective to individual layer ink (tusche), but poor to multilayer ink effect, the requirement of present glass deinking can not be met.
Summary of the invention
The object of the invention is for overcoming existing technical problem, a kind of energy-conserving and environment-protective, use range is wide, deinking efficiency is better glass deinking agent are provided.
The technique means that the present invention adopts is:
