Heat transfer printing colored tape for metal material and preparation method thereof

Abstract

The invention discloses a heat transfer printing colored tape for a metal material. The heat transfer printing colored tape comprises a tape base, an ink layer coated on one side of the tape base, and a heat resistant coating layer coated on the other side of the tape base; and the ink layer comprises the following raw materials in parts by weight: 35-38 parts of acrylic resins, 16-20 parts of epoxy resins, 31-34 parts of carnauba wax, 14-18 parts of lignite wax, 8-12 parts of tetra hydro phthalic anhydride, 17-20 parts of carbon black, 6-9 parts of sodium bentonite, 3-5 parts of montmorillonoid, 1-4 parts of aluminum phosphate, 4-6 parts of propylene glycol monomethyl ether, 1-2 parts of modified polyurea, and 1-5 parts of polydimethylsiloxane. The invention further discloses a preparation method of the heat transfer printing colored tape for the metal material. The heat transfer printing colored tape can clearly print on a metal printing medium, and widens the application range.

Description

technical field [0001] The invention relates to the technical field of thermal transfer ribbons, in particular to a thermal transfer ribbon for metal materials and a preparation method thereof. Background technique [0002] Thermal transfer ribbon is a necessary consumable material for thermal transfer printing, and it is also the core material that determines the quality of thermal transfer printing. Thermal transfer ribbon transfers the ink layer on the ribbon to the paper by combining heat and pressure. It is a kind of printing consumables on the market, which dissolves the ink on the ribbon with temperature and pressure, and then hot stamps the ink on the label. It is suitable for printing identification and marking information such as production date, batch number, weight, etc., and can realize clear printing of characters , The printed handwriting has the characteristics of clear, firm, scratch-resistant, and cooking-resistant. With the rapid development of my country...

Problems solved by technology

[0003] With the development of social needs and the updating of technology, the printing medium of thermal transfer method has developed from a single paper (plain paper, recycled paper, synthetic paper, envelope, label paper) to plastic (PET, PVC, PP, PE, etc.) , fibers, composite materials, cloth, ceramics, calendering materials, etc., but for metal materials (such as aluminum, magnesium aluminum alloy, tinplate, stainless steel), there is currently no applicable thermal transfer ribbon, because of its special properties, When printing with thermal transfer ribbon on the material, it is prone to problems such as poor adhesion, poor scratch resistance, unclear and complete patterns and characters
