Problems solved by technology

When the unprotected glass is cut or edged in the subsequent processing, the surface of the glass is easy to cause slight or severe scratches, and it takes a long time to polish it, which consumes a lot of polishing powder and cannot be polished. directly scrapped
The glass protected by peelable protective glue or protective film, although it can protect the glass to a certain extent in the subsequent processing process, the protective glue / protective film needs to be manually peeled off, and it is often easy to leave residual glue and in the process. The glass is scratched during the stripping operation, and the remaining glue is difficult to remove, the stripping operation consumes a lot of manpower, and the process efficiency is low

Embodiment 1

[0035] Embodiment 1: the synthesis of epoxy acrylic resin

[0036] Take 424g of epoxy resin (epoxy equivalent of 212), 130g of acrylic acid, 0.65g of hydroquinone, and 0.6g of benzylamine, add them into a three-necked flask, heat to 100°C, and react for 3 hours to obtain an acid value of less than 5mg(KOH) / The composition of g; at this time, cool down to 80°C, add 202g of phthalic anhydride, heat to 100°C after the phthalic anhydride dissolves, and react for 4 hours to obtain an epoxy acrylic resin with an acid value of 80-120mg (KOH) / g. Its chemical structural formula is as follows:

[0037]

[0038] Among them, R 2 for n≈4.5.

Embodiment 2

[0039] Embodiment 2: the synthesis of polyurethane acrylic resin

[0040] Take isophorone diisocyanate (IPDI) 300g, hydroxyethyl methacrylate (HEMA) 244.4g, hydroquinone 0.5g, dibutyltin oxide 0.1g, heat to 60°C for 3 hours, then add polyethylene Diol (PEG 300 ) of 284 g, continue to heat to 70° C. for 4 hours, and monitor the content of -NCO by infrared spectroscopy until the reaction of -NCO is complete to obtain the polyurethane acrylic resin. Its chemical structural formula is as follows:

[0041]

Embodiment 3

[0042] Embodiment 3: Preparation of UV-curable glass protection ink

[0043] Weigh each component according to the following weight percentage, disperse and mix each component and then grind to prepare the UV curing glass protection ink:

Abstract

The invention discloses a glass protecting ink and a preparation method thereof. The glass protecting ink comprises the following components in percentage by weight: 10%-30% of polyurethane acrylate, 5%-30% of epoxy acrylic resin, 5%-40% of phenolic resin, 20%-50% of acrylic monomer, 2%-10% of initiator, 1%-5% of adhesion promoter, 1%-5% of thixotropic agent, 0.5%-2% of dispersing agent, 0.2%-4% of surface active agent, 1%-5% of pigment and 10%-30% of filler. The glass protecting ink disclosed by the invention has a good glass protecting performance, is easy to strip, and is convenient to operate.

Description

technical field [0001] The invention relates to a glass protection ink and a preparation method thereof. Background technique [0002] In the traditional glass processing technology, the glass to be processed is usually in an unprotected state, or it is protected with a peelable protective glue or protective film. When the unprotected glass is cut or edged in the subsequent processing, the surface of the glass is easy to cause slight or severe scratches, and it takes a long time to polish it, which consumes a lot of polishing powder and cannot be polished. directly discarded. The glass protected by peelable protective glue or protective film, although it can protect the glass to a certain extent in the subsequent processing process, the protective glue / protective film needs to be manually peeled off, and it is often easy to leave residual glue and in the process. The glass is scratched during the stripping operation, and it is difficult to remove the excess glue. The strip...
