Problems solved by technology

[0003] The preparation of thermal paper generally requires a protective layer on the surface. The protective layer provides a protective function for the surface of the thermal paper. The emulsion-type polyacrylate emulsion-type film-forming material is environmentally friendly, excellent in weather resistance and low carbon. and other characteristics, in recent years has been greatly developed, but the emulsion polyacrylate emulsion coating has not been applied on thermal paper

Abstract

The invention relates to the field of thermo-sensitive paper coating and a preparation method thereof. Provided is an emulsion type coating for thermo-sensitive paper, which comprises the following components in parts by weight: 25-30 parts of active acrylate monomer, 15-20 parts of ionic liquid modified carbon black, 5-8 parts of glass fibers, 1-3 parts of natural plant essential oil, 4-7 parts of carboxylic acid, 17-25 parts of pigment filler, 3-5 parts of a surfactant, 1-6 parts of a composite emulsifier and 12-20 parts of hydroxypropyl methyl cellulose. The emulsion type coating for thermo-sensitive paper has the advantages that VOC (volatile organic compounds) released by the emulsion type coating is less, pollution to human bodies and environments is reduced, and the emulsion type coating is long in storage time and easy to store.

Description

technical field [0001] The invention relates to the field of heat-sensitive paper paint and a preparation method thereof, in particular to an emulsion-type paint for heat-sensitive paper and a preparation method thereof. Background technique [0002] Thermal paper is a printing paper specially used for thermal printers and thermal fax machines. At present, thermal paper has been widely used in e-commerce, logistics labels, online reservation tickets, lottery tickets, handheld terminal vouchers, electronic invoices, automatic Parking tickets, train and subway bills, personalized handbook printing paper, etc. are all aspects of people's lives. [0003] The preparation of thermal paper generally requires a protective layer on the surface. The protective layer provides a protective function for the surface of the thermal paper. The emulsion-type polyacrylate emulsion-type film-forming material is environmentally friendly, excellent in weather resistance and low carbon. And othe...
