Technical Field
The invention relates to the field of glass cleaning, in particular to an acidic cleaning agent and a preparation method and application thereof.
Background
In the production process of a glass element, in order to reduce the roughness of the glass surface, the surface of the glass needs to be polished. The surface of the glass is usually polished by using polishing powder during the polishing process, and a part of the polishing powder remains on the surface of the glass after polishing. On one hand, the polishing powder particles remained on the surface of the glass element can corrode the surface of the glass element, for example, the polishing powder particles remained on the optical glass element after precision polishing are one of the key factors influencing the laser irradiation damage resistance of the element; on the other hand, after the glass component is assembled on the electronic product, the polishing powder remained on the surface of the glass component can seriously affect the stability and reliability of the electronic product, and even lead to the failure of the electronic product.
For the polishing powder remained on the glass, an alkaline cleaning agent mainly comprising strong alkali or an acidic cleaning agent mainly comprising acid is generally adopted in the traditional technology; both of them use acid or alkali to provide the pH value system needed by the cleaning agent, and the purpose of cleaning the polishing powder is achieved through the matching of other auxiliary agents. However, electronic glass components are mainly made of high-alumina silicate, the main component of the electronic glass components is silicon dioxide, and the traditional alkaline cleaning agent can cause glass corrosion due to too strong alkalinity, so that poor phenomena such as haze, scratch, blue and the like can occur; in the traditional acidic cleaning agent, the surface active agent, the dispersing agent and other auxiliaries are added into an acidic system, so that the polishing powder on the surface of the glass is cleaned, the inspection qualification rate of the cleaned glass reaches more than 98% under a three-wave lamp, but the problem of low removal efficiency of the polishing powder exists.
Therefore, how to provide the cleaning agent with high cleaning efficiency and small damage to glass has great significance.

Advantageous effects
In the acid cleaning agent, organic acid, inorganic acid and pH buffering agent in specific proportion are adopted for matching to provide a specific acid cleaning environment, and in the acid environment, polishing powder shows strong oxidizing property; meanwhile, the reducing agent with a specific ratio is added, so that the polishing powder rapidly reacts with the reducing agent in a specific acid environment, and the polishing powder can be rapidly treated by coordinating the components with the specific ratio through the wetting and dispersing effects of the chelating agent and the surfactant with the specific ratio, and the glass is not damaged.

Detailed Description
In order that the invention may be more fully understood, a more particular description of the invention will now be rendered by reference to specific embodiments thereof that are illustrated in the appended drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
One embodiment of the present invention provides an acidic cleaning agent, which comprises the following components: 5 to 20 percent of organic acid, 3 to 10 percent of inorganic acid, 5 to 30 percent of reducing agent, 1 to 8 percent of pH buffering agent, 1 to 8 percent of surfactant, 1 to 5 percent of chelating agent and the balance of water.
In the acid cleaning agent, organic acid, inorganic acid and pH buffering agent in specific proportion are adopted for matching to provide a specific acid cleaning environment, and the polishing powder shows strong oxidizing property in the acid environment; meanwhile, the reducing agent with a specific ratio is added, so that the polishing powder rapidly reacts with the reducing agent in a specific acid environment, and the polishing powder can be rapidly treated by coordinating the components with the specific ratio through the wetting and dispersing effects of the chelating agent and the surfactant with the specific ratio, and the glass is not damaged.
In some embodiments, the organic acid is present in an amount of 10 to 15% by weight.
Too high a ratio of the organic acid adversely affects the performance of the surfactant and other auxiliaries, while too low a ratio thereof is consumed rapidly during the cleaning process, thereby failing to provide a specific acidic environment and reducing the cleaning efficiency of the polishing powder.
The organic acid includes carboxyl (-COOH), sulfonic acid (-SO)3H) Sulfinic acids, organophosphonic acids, and the like, including but not limited to: acetic acid, propionic acid, butyric acid, succinic acid, benzoic acid, oxalic acid, tartaric acid, citric acid, hydroxyethylidene diphosphonic acid and 2, 4-dimethylbenzenesulfonic acid.
In some embodiments, the organic acid is selected from one or more of citric acid, oxalic acid, hydroxyethylidene diphosphonic acid and 2, 4-dimethyl benzene sulfonic acid.
Preferably, the organic acid is at least one selected from the group consisting of citric acid and hydroxyethylidene diphosphonic acid.
In some embodiments, the inorganic acid is 3 to 5% by weight.
The inorganic acid is used for supplementing the hydrogen ion concentration in the acidic cleaning agent system, so that the acidic cleaning can maintain a specific acidic environment; too high a proportion of the inorganic acid may adversely affect the surface activity and other additives, and too low a proportion may result in failure to maintain a specific acidic environment for acidic cleaning, and thus the cleaning efficiency of the polishing powder may be lowered.
In some embodiments, the inorganic acid is selected from one or more of sulfuric acid, phosphoric acid, nitric acid, and boric acid.
Preferably, the inorganic acid is at least one selected from the group consisting of sulfuric acid and phosphoric acid.
In some embodiments, the pH buffer is 3% to 5% by weight.
The pH buffering agent can adjust the pH value of an acid cleaning agent system, so that the acid cleaning can maintain a specific acid environment, and when the polishing powder on the glass is cleaned, the reducing agent can be ensured to react with the polishing powder in time, so that the polishing powder on the surface of the glass can be treated very quickly, and the glass is not damaged.
In some embodiments, the pH buffer is selected from one or more of sodium citrate, sodium gluconate, and glycine.
Preferably, the pH buffering agent is selected from glycine.
In some embodiments, the pH value of the acidic cleaning agent is 0.5-4.
Organic acid, inorganic acid and pH buffering agent in specific proportion are adopted for matching to provide a specific acid cleaning environment, and the polishing powder shows strong oxidizing property in the acid environment; meanwhile, the reducing agent with a specific ratio is added, so that the polishing powder and the reducing agent quickly undergo chemical reaction in a specific acid environment, and the cleaning efficiency of the polishing powder is improved.
In some embodiments, the reducing agent is 15 to 30% by mass.
The acidic cleaning agent provided by the invention provides a characteristic acidic environment, the polishing powder shows strong oxidizing property, the reducing agent with a specific proportion is added, so that the polishing powder and the reducing agent quickly generate chemical reaction in the specific acidic environment, the proportion of the reducing agent is too low, and the cleaning efficiency of the polishing powder is reduced. When the mass percent of the reducing agent is 15-30%, the cleaning efficiency of the polishing powder can be further improved.
In some embodiments, the reducing agent is selected from one or more of hydrogen peroxide, ferrous sulfate, thiourea and ascorbic acid.
Preferably, the reducing agent is one or two selected from thiourea and ascorbic acid.
In the characteristic acid environment provided by the acid cleaning agent, one or two of thiourea and ascorbic acid are used as reducing agents and react with the polishing powder more quickly, so that the cleaning efficiency of the polishing powder can be further improved.
In some embodiments, the chelating agent is 2 to 4% by mass.
In some embodiments, the chelating agent is selected from one or more of sodium citrate, ethylenediaminetetraacetic acid (EDTA), sodium gluconate, and nitrilotriacetic acid.
Preferably, the chelating agent is one or more selected from Ethylene Diamine Tetraacetic Acid (EDTA), sodium gluconate, and nitrilotriacetic acid.
In some embodiments, the surfactant is 2% to 5% by weight.
The chelating agent has a dispersing function, the surfactant has a wetting and dispersing function, and the surface tension of the acidic cleaning agent can be further reduced, so that the contact area of the acidic cleaning agent and the residual polishing powder on the surface of the glass is increased, and meanwhile, the product of the chemical reaction of the polishing powder and the reducing agent in a specific acidic environment is dispersed in the acidic cleaning agent, so that the polishing powder on the surface of the glass can be very quickly treated, and the glass is not damaged.
