Embodiment

[0009] Embodiment: first take silver powder and diluent and mix it into a special medium for later use, then weigh 5KG of the above-mentioned medium, 3.5KG of imported water-based color ink, and 1.5KG of viscous agent to prepare evenly for later use. Then through the gravure embossing technology of the production equipment, the silver paste is printed on the substrate, and then the imported temperature control system is equipped with a high-efficiency radiator. For the first heating and drying, the temperature is controlled at 120 degrees to prevent discoloration and deformation. Then it is sent to the second oven through a 3-meter-long conveyor belt, and the oil in the oil tank is circulated to the refueling drum through a high-efficiency circulating oil pump. The temperature is controlled at 200 degrees, and the product is shaped and strengthened again, so that the The peculiar smell is completely dissipated, making the product more three-dimensional and more stable. Accord...

Abstract

The invention discloses a silver paste transfer printing process. The silver paste transfer printing process comprises the following steps: step 1, silver paste containing colored ink is print-formed on a substrate through intaglio printing; step 2, the substrate is heated and shaped for the first time, wherein the temperature is controlled at 120+ / -0.5 DEG C; step3, the substrate which is heated and shaped for the first time is conveyed to a second drying oven to be shaped again, wherein the temperature is controlled at 200+ / -0.5 DEG C. As optimization, the silver paste containing the colored ink in the step 1 is formed by mixing raw materials including, by weight, 50 parts of a medium, 35 parts of imported colored ink, and 15 parts of pasting agents, wherein the medium is formed by mixing silver powder and a diluting solvent. The silver paste transfer printing process has the advantages that constituents of the silver paste are mixed in an optimized mode; meanwhile, the method of heating and shaping for two times is adopted, so that printed wallpaper is stronger in stereoscopic impression, better in stability, and not prone to discoloration and deformation; moreover, the steps are simple, easy to implement, and more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of printing and packaging, and in particular relates to a silver paste transfer printing process. Background technique [0002] Silver paste ink is a kind of aluminum powder ink. Aluminum powder ink is the most widely used and most diverse type of metal ink. It has a good metal effect and has a huge market demand. Aluminum powder has a good ability to reflect light, forms a good metal film in the ink, can reflect visible light, ultraviolet rays and infrared rays, and is silvery white when it reflects visible light, making it have good decorative and covering properties; the reflection of ultraviolet rays can be Protect the coating from ultraviolet damage and prolong the life of the coating; the reflection of infrared rays makes it have the thermal insulation performance of reflecting heat radiation. After nearly a century of continuous development, aluminum powder ink has become an important member of the m...
