Problems solved by technology

[0006] 3. Low chroma of paper base coating
[0011] There are many kinds of chemicals used in thermal paper, but the research on adhesives for three-proof thermal paper is still blank. The key to the production of three-proof thermal paper is adhesives. At present, some thermal papers are produced using PVA modification, or other Adhesives, the product quality does not meet the requirements, resulting in a lot of waste

Abstract

The invention belongs to chemical materials in the field of new materials, in particular to an emulsion polymer adhesive used for waterproof, oil-proof and antifriction thermal sensitive paper. The emulsion polymer adhesive comprises the following components in percentage by weight: acrylamide, acrylic acid or methacrylic acid, butyl acrylate, methyl methacrylate, hydroxypropyl methacrylate, acrylonitrile and the like. The emulsion polymer adhesive used for the waterproof, oil-proof and antifriction thermal sensitive paper has the advantages of high viscosity stability, heat resistance, bonding strength, color sensitivity and waterproof, oil-proof and antifriction performance and capability of meeting the environmental protection requirement.

Description

technical field [0001] The invention belongs to chemical materials in the field of new materials, in particular to an emulsion polymer adhesive used for three-proof heat-sensitive paper. Background technique [0002] Thermal paper was industrialized in the 1970s by NCR Corporation of the United States. The world’s thermal paper is increasing at a rate of 20-25% per year, and its application fields are constantly expanding, except for some commercial and household thermal faxes. Outside the machine, more thermal paper is also widely used in word processors, printing records of medical testing and industrial testing, printing of cash automatic payment machines and portable terminal printers, receipt records of highways, taxis, etc., and the rapid development thermal labels and tickets. Three-proof thermal paper is mainly used for thermal labels (food packaging, logistics label paper), train tickets, movie tickets, lottery tickets, plane boarding passes, etc. Three-proof ther...
