AI Technical Summary
Technical Problem
The existing light-shielding tape is prone to fingerprint shading problems during use, and the water-based polyurethane matrix material used is added with carbon black and additives, resulting in poor anti-friction performance and appearance of the coating.
Method used
采用由水性聚氨酯树脂制成的耐指纹哑光涂层,涂层中加入0.3~2%的PE型蜡粉,并通过设置涂层厚度为3~6μm,结合PET膜层、压敏胶层和离型膜层的设计,提升胶带的抗摩擦性能和美观度。
Benefits of technology
The matte and fingerprint resistance of the tape are achieved, while effectively improving the anti-friction performance and aesthetics, avoiding defects caused by excessive or excessive coating thickness.

Abstract
The utility model provides a fingerprint-resistant shading adhesive tape which comprises a release film layer, a pressure-sensitive adhesive layer, a PET (polyethylene terephthalate) film layer and a fingerprint-resistant matte coating which are sequentially arranged from top to bottom, the PET film layer is a black PET film layer, the fingerprint-resistant matte coating is a waterborne polyurethane coating, and the thickness of the waterborne polyurethane coating is 3-6 microns. According to the fingerprint-resistant shading adhesive tape provided by the utility model, the fingerprint-resistant matte coating is prepared from the waterborne polyurethane resin, so that after the fingerprint-resistant matte coating is coated, the fingerprint-resistant shading adhesive tape has the characteristics of matte and fingerprint resistance, and the thickness of the waterborne polyurethane resin coating is set to be 3-6 microns; the condition that the overall thickness of the fingerprint-resistant shading adhesive tape is increased due to the fact that the thickness of the coating is too small and the thickness of the coating is too large can be effectively avoided, the overall attractiveness of the fingerprint-resistant shading adhesive tape is improved, and the friction resistance of the fingerprint-resistant shading adhesive tape is effectively improved.
