Alkaline polished TP cover plate glass cleaning agent

Abstract

The invention belongs to the field of cleaning materials, and particularly relates to an alkaline polished TP cover plate glass cleaning agent which comprises the following components in percentage by mass: 5-30% of inorganic alkali, 5-10% of organic alkali, 3-15% of a chelating agent, 1-10% of an efficient dispersing agent, 5-15% of an anionic fatty alcohol ether gemini surfactant, 1-5% of a bacteriostatic agent and 50-70% of deionized water. By adopting the anionic fatty alcohol ether gemini surfactant, silica gel offset printing attached to the surface of the glass subjected to screen printing can be softened and rolled away, the problem that a large amount of offset printing and silicone oil exist on the surface of the cleaned glass is effectively solved, and meanwhile the cleaning agent has a remarkable cleaning effect on grinding powder, polishing powder, oil stains, fingerprints and inorganic matter residues. The cleaning agent is especially suitable for cleaning engraving glass, AG glass and mobile phone optical glass, is good in component stability and small in smell, and has a good application prospect in a cleaning procedure after CMP (Chemical Mechanical Polishing).

Description

technical field [0001] The invention belongs to the technical field of cleaning materials, and in particular relates to a cleaning agent for TP cover glass after alkaline polishing. Background technique [0002] With the continuous innovation of real technology, real products are gradually developing in the direction of flatness, thinness, high definition, high resolution, and green environmental protection. In the production process of TP cover glass, in order to increase the surface stress of the glass so that the glass can achieve the effect of scratch resistance and impact resistance, the glass will be placed in a potassium nitrate solution at 170-400 ° C to let the sodium on the glass surface The ions are fully ion-exchanged with the potassium ions of the potassium nitrate solution. Because the volume of potassium ions is larger than that of sodium ions, the mutual extrusion of potassium ions forms a stress layer on the glass surface, thereby achieving the effect of gl...

Problems solved by technology

In this process, the silicone gasket used to absorb glass tends to leave obvious offset and silicone oil on the AG surface of the glass, which affects product quality and cannot meet the needs of downstream customers.

The current industry adopts pickling and organic solvent cleaning methods, the cleaning effect is relatively limited, the cost is also high, which affects the production efficiency, and may cause secondary pollution to the glass substrate
