Embodiment 1

[0031] Weigh 10kg of M800A silver paste, 20kg of M800B silver paste and 25kg of M800C silver paste, stir and mix evenly to obtain conductive silver paste. Then the polyester resin of 44kg, the conductive silver paste of 55kg, the alcohol ether solvent of 8kg and the ethyl acetate of 3kg are stirred and mixed to obtain the high-gloss anti-stretch mirror silver ink.

[0032] Add 3kg of butyl acetate to the high-gloss anti-stretch mirror silver ink, stir evenly, and use screen printing (300 mesh screen) to print the high-gloss anti-stretch mirror silver ink with butyl acetate on the PC substrate After printing, place the semi-finished product at 20°C to 25°C for 25 minutes, then bake the semi-finished product at 80°C for 30 minutes to achieve surface dryness, and print the anti- Impact ink and high-temperature-resistant adhesive, so that the thickness of the ink on the PC substrate reaches 25 μm. After printing, it is baked and dried at 90 ° C for 60 minutes to achieve thorough d...

Embodiment 2

[0035] Weigh 6kg of M800A silver paste, 20kg of M800B silver paste and 30kg of M800C silver paste, stir and mix evenly to obtain conductive silver paste. Then, the polyester resin of 30kg, the conductive silver paste of 40kg, the alcohol ether solvent of 5kg and the ethyl acetate of 3kg were stirred and mixed uniformly to obtain the high-gloss anti-stretch mirror silver ink.

[0036] Add 3kg of butyl acetate to the high-gloss anti-stretch mirror silver ink, stir evenly, and print the high-gloss anti-stretch mirror silver ink with butyl acetate on the transparent PET substrate by screen printing (250 mesh screen) After printing, place the semi-finished product at 20°C to 25°C for 20 minutes, then bake the semi-finished product at 70°C for 40 minutes to dry the surface, and print in full on the surface of the dry high-gloss anti-stretch mirror silver ink The impact-resistant ink and high-temperature-resistant adhesive make the thickness of the ink on the PET substrate reach 20 μ...

Embodiment 3

[0039] Weigh 11kg of M800A silver paste, 22kg of M800B silver paste and 27.5kg of M800C silver paste, stir and mix evenly to obtain conductive silver paste. Then the polyester resin of 50kg, the conductive silver paste of 60kg, the alcohol ether solvent of 12kg and the ethyl acetate of 8kg are stirred and mixed uniformly to obtain the high-gloss anti-stretch mirror silver ink.

[0040] Add 10kg of butyl acetate to the high-gloss anti-stretch mirror silver ink, stir evenly, and use screen printing (350 mesh screen) to print the high-gloss anti-stretch mirror silver ink with butyl acetate on the transparent PET substrate After printing, place the semi-finished product at 20°C to 25°C for 30 minutes, then bake the semi-finished product at 85°C for 25 minutes to dry the surface, and print in full on the surface of the dry high-gloss anti-stretch mirror silver ink The impact-resistant ink and high-temperature-resistant adhesive make the thickness of the ink on the PET substrate rea...

Abstract

The invention relates to highlight stretch-proof mirror-like silver ink and a using method thereof. The highlight stretch-proof mirror-like silver ink is prepared from, by mass, 30-50 parts of polyvinyl acetate resin, 40-60 parts of conductive silver paste, 5-12 parts of an alcohol ether solvent and 3-8 parts of ethyl acetate. The tensile amplitude of the highlight tensile mirror-like silver ink reaches 3 microns, the brightness of the highlight tensile mirror-like silver ink reaches 87 or above, the highlight tensile mirror-like silver ink is good in printing adhesion and high in shielding performance on various PC, transparent PET and other materials, and an ink layer is not broken after injection molding.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a high-gloss anti-stretch mirror silver ink and a use method thereof. Background technique [0002] In recent years, printed products have penetrated into all social strata at an astonishing speed. In order to meet the individuation, diversification and flexibility of printed matter, the quality requirements are becoming more and more stringent. Facing the competition of label quality, production quality determines the competitive advantage of labels. At present, in the printing label industry, there are many products with screen printing mirror silver on the reverse side of transparent PC and PET materials, because some of these label products (such as mobile phone back covers, thin mold switches, etc.) need post-processing such as injection molding and stretching , the quality of its mirror effect determines the competitive advantage of the appearance of the product. If the print...
