Problems solved by technology

Generally, UV glue with good adhesion to PET is often added with some viscosity-increasing components to increase its adhesion to PET, which is easy to cause corrosion to the conductive circuit of the breathing lamp.
Document CN108130037A discloses an adhesive for bonding non-surface-treated PET. Its components include: 40-70 parts of silicone-modified polyurethane acrylate oligomer, 10-30 parts of acrylate monomer, and 20 parts of tackifier -40 parts, 1-5 parts of photoinitiator, 1-5 parts of filler, 0.1-3 parts of functional additives, which mainly use tackifier to play a bonding effect on PET corrosion, and also cause conductive lines corroded

The UV-curable black glue composition includes the following components in parts by weight: 30-60 parts of polyurethane acrylate oligomer, 20-70 parts of large molecular weight acrylate monomer, and 1-5 parts of epoxy resin , 1-5 parts of photoinitiator, 0.2-4 parts of carbon black.

Description

technical field [0001] The invention relates to an ultraviolet light-curable black glue composition for a keyboard breathing lamp and an application thereof. Background technique [0002] With the development of society, computer keyboards are becoming more and more gorgeous in appearance, mainly because there are a lot of breathing lights on the keyboard. On the one hand, it is to show individuality and be different; backlighting. The breathing light can also help users recognize the numbers on the keyboard in low light. However, there are also many production-related problems, such as the cost will increase a lot and the power consumption will increase. The most important problem is the scattering of light, which greatly affects the effect of the breathing lamp. The solution is to put a circle of shading glue around the breathing lamp so that the light can be concentrated in one direction. The base of the breathing lamp is generally made of PET material, which is a hig...
