Description

A shellac cleaning agent

technical field

The invention relates to a shellac cleaning agent, which belongs to the field of cleaning agents.

technical background

The glass surface of mobile phone glass must be protected before etching and tempering. Due to different processes, the protection methods adopted are also different. Some use peelable blue glue, some use acid-resistant film, and some use light-curable shellac. Since shellac is directly dissolved in the cleaning process in the subsequent cleaning process, the process is relatively simple and is adopted by most enterprises. However, shellac is relatively harsh in the subsequent selection of cleaning agents. General cleaning agents have many defects during use, such as incomplete glue removal, residual glue on the surface, or glue agglomeration and sticking to the glass surface after glue removal, or unclean removal of oil stains on the glass surface, or corrosion on the glass surface, Causes scratches on the surface of the glass.

Contents of the invention

The object of the present invention is to provide a kind of cleaning agent that can satisfy shellac cleaning in view of the deficiencies of existing cleaning agents.

In order to achieve the above object, the present invention adopts the following technical solutions:

A shellac cleaning agent, its main component and dosage include: 5-15 parts of potassium hydroxide, 5-10 parts of EDTA-4Na, 20-40 parts of monoethanolamine, 3-10 parts of TX-10 phosphate, 1-10 parts of potassium carbonate 5 parts, 1-5 parts of sodium gluconate, 10 parts of low-foaming alkyl glycoside FC-393, and the rest of water.

The main components and dosage are preferably 10 parts of potassium hydroxide, 7 parts of EDTA-4Na, 30 parts of monoethanolamine, 5 parts of TX-10 phosphate, 3 parts of potassium carbonate, 2 parts of sodium gluconate, and 395 parts of low-foaming alkyl glycosides , the water balance.

The preparation method of described a kind of shellac cleaning agent, its steps are as follows:

1) First add monoethanolamine and TX-10 phosphate together and stir evenly, then add water and stir evenly.

2) Add EDTA-4Na, potassium carbonate, sodium gluconate and potassium hydroxide to the above mixture and stir well.

3) Add FC-39 and stir evenly to obtain a yellow liquid product.

The using method of described lac cleaning agent:

The lac cleaning agent of the present invention is prepared into a concentration of 5-10% with deionized water for use. Soak the glass that needs shellac removal in a tank filled with shellac cleaning agent, heat it to 70-80°C, and rinse it with clean water after the glue and oil stains on the glass are completely removed.

The present invention is a kind of lac cleaning agent, has following remarkable advantage compared with existing commercially available cleaning agent:

1. Strong glue removal ability, no residue and easy to rinse.

2. After the glue is removed, the glue will not be agglomerated or anti-sticky, and it will completely dissolve in the cleaning agent.

3. No corrosion to glass, high cleaning yield.
