Flexible temperature-resistant printing magnetic membrane material and preparation method thereof

Abstract

The invention discloses a flexible temperature-resistant printing magnetic membrane material. The flexible temperature-resistant printing magnetic membrane material is composed of a printing PVC membrane layer, a PET membrane layer and a magnetic layer which are tightly connected in sequence, and is characterized in that the PET membrane is transparent, and the thickness of the PET membrane layeris 0.005-0.08 mm. The flexible temperature-resistant printing magnetic membrane material has the advantages that compared with a product of the same structure, the PET membrane becomes thinner, Latexprinting of the flexible printing magnetic membrane material can be still guaranteed, meanwhile, printing quality is improved, the flexibility of the product is guaranteed, a thickness space is provided for the magnetic layer, and accordingly the magnetic property of the product can be better exerted; the flexible temperature-resistant printing magnetic membrane material is high in generality, further suitable for curing of a weak solvent, a solvent and UV, and suitable for digital printing, air brush, offset print and others.

Description

technical field [0001] The invention relates to the field of magnetic materials, in particular to a flexible temperature-resistant printable magnetic diaphragm material and a preparation method thereof. Background technique [0002] The magnetic diaphragm material used in the printing industry, because of the combination of printable and magnetic functions, has brought an upgrade to the products in the advertising, decoration and other industries. The corresponding printing consumables must be suitable for UV, solvent, and weak solvent printing methods. However, with the emergence of latex printing in the printing industry, higher requirements are placed on printing consumables, because the curing temperature of latex inks is higher than that of conventional UV, solvent, and weak solvents, and printing consumables must adapt to this temperature resistance requirement. , while ensuring uniform printing quality, no ink smudges, no loss of flexibility to accommodate temperature...

AI Technical Summary

Problems solved by technology

[0006] It can be seen from the above that in the existing printing material technology, PET film is usually only used as a supporting component of the diaphragm material. As a skeleton material, its mechanical properties are fully utilized to achieve the stiffness of the product. There are also many PVC films in the prior art of printing consumables. Sheets and PET films are used in combination to take advantage of the thermal and mechanical properties of PET, but they generally solve the problem of weather resistance and meet the mechanical and thermal properties at the same time. In order to meet the requirements of latex printing, the instantaneous high temperature that needs to be met The usual method is to increase the overall thickness of the product, especially the thickness of the PET film to meet the challenges brought about by the temperature rise. It is considered that the PET film must have the necessary thickness, and the inertial thinking leads to no thinner. try
