Description

Technical Field

[0001] The invention relates to the technical field of UV curing glue sols, in particular to a sol for UV curing glue on glass surfaces. Background Art

[0002] UV-curable adhesive is a type of adhesive that cures and hardens through ultraviolet (UV) radiation. It is primarily composed of a photoinitiator, monomers, and polymers. Under UV radiation, the photoinitiator absorbs UV light and releases free radicals or cations, which in turn initiate the polymerization reaction of the monomers and polymers in the adhesive, causing it to cure rapidly.

[0003] UV-curing adhesives typically have very strong adhesion after curing, making them difficult to remove during the glass recycling process. This is because the molecular structure of UV-curing adhesives forms a strong polymer network under ultraviolet light, making them difficult to decompose. When recycling glass, if there is residual UV adhesive on the glass surface, it can complicate the recycling process and require additional cleaning and decomposition steps. Therefore, for better glass recycling, UV-curing adhesive sols are required.

[0004] The UV curing sols currently on the market have the following disadvantages:

[0005] 1. Most of them can only dissolve UV glue that has not been formally hardened. They cannot dissolve UV glue that has been formally cured, or the dissolution speed is slow and requires more than dozens of hours of soaking;

[0006] 2. Most of them are alkaline, with a pH greater than 10. They are corrosive to the glass itself during the soaking process and will destroy the smoothness of the surface;

[0007] 3. Since there are many manufacturers of UV glue, different manufacturers' UV glue has different characteristics. The existing solvents have poor compatibility. Different solvents are required for different glues, and the scope of use is narrow.

[0008] Based on the above problems, the present application proposes a sol for UV curing adhesive on glass surface. Summary of the Invention

[0009] The purpose of the present invention is to provide a sol agent for UV curing adhesive on glass surface to solve the problems in the above background technology.

[0010] To achieve the above object, the present invention provides the following technical solution: a sol for UV curing adhesive on glass surface, comprising the following components in parts by mass:

[0011] 65-90 parts of ethanol, 1-3 parts of surfactant, 0.9-2.2 parts of corrosion inhibitor, 0.5-1.2 parts of thickener, 1-3 parts of limonene, 2-5 parts of glycerol, 6-15 parts of vegetable oil, 3-6 parts of alkyl glycoside, and 1.5-3 parts of gamma-butyrolactone.

[0012] Preferably, the surfactant is one or more of alkyl-free phenol, polyoxyethylene-polyoxypropylene block copolymer or polyether-modified silicone.

[0013] Preferably, the sustained-release agent is one or more of benzotriazole, methylbenzotriazole or sodium silicate.

[0014] Preferably, the thickener is one or more of silicon dioxide, bentonite, and acrylate.

[0019] The present invention provides a sol for UV curing adhesive on glass surface. The obtained product is neutral and does not corrode the glass after long-term immersion. The glass after debonding can be directly put into use, reducing the loss of repair. The invention has good dissolving ability for common glues on the market and is more versatile. The service life is extended and no replacement is required. It only needs to be added when the solution is insufficient, reducing replacement. DETAILED DESCRIPTION

[0046] The role of the surfactant in the present invention is to reduce the surface tension of the glue, improve the coating effect, and make the glue layer evenly distributed. In addition, it helps to disperse the various components in the glue and prevent stratification. The corrosion inhibitor is used to prevent the glass surface from being corroded in the glue, and can protect the surface to avoid the production of corrosive products due to long-term contact or reaction. The thickener is used to adjust the viscosity of the glue to give it appropriate fluidity and workability so that it does not sag during coating, while ensuring the thickness and consistency of the glue layer. Limonene is a natural solvent that is often used to improve the odor of the formula and has certain solubility properties for certain components of UV curing glue. In addition, limonene is also a slight synergist that helps to improve the fluidity and gloss of the glue. Glycerin has a skin protection function to avoid irritation to human skin during use. Vegetable oil has a certain dissolving effect on UV curing glue and is green and environmentally friendly.

[0049] In summary, the product produced by the present invention is neutral and can completely remove UV-curing adhesive from glass surfaces without causing scratches, facilitating glass recycling. Furthermore, it can dissolve a variety of common commercially available adhesives, making it more versatile. Furthermore, it has a longer service life and does not require replacement, requiring only replenishment when the solution is insufficient, thus reducing replacement times.
