Problems solved by technology

[0003] At present, there is no adhesive specially designed for thermal paper coating on the market, and some ordinary acrylate emulsions or polyvinyl alcohol and other high molecular polymers are basically used. Although these polymers have a certain adhesive effect, However, it does not address some characteristics of thermal paper, such as thermal color development, color retention, temperature and humidity tolerance, etc.

Abstract

The invention relates to a coating adhesive for thermal copy paper, which consists of the following components: 65 parts of butyl acrylate, 6 parts of methyl acrylate, 15 parts of methyl methacrylate, 80 parts of styrene, 3 parts of hydroxyethyl acrylate 4 parts, glycidyl methacrylate 4 parts, acrylic acid 5 parts, methacrylic acid 6.5 parts, diacetone acrylamide 6 parts, adipate dihydrazide 4 parts, octamethylcyclotetrasiloxane 7 parts, methyl 2 parts of acryloxypropyl trimethoxysilane, 1.8 parts of allyloxy nonylphenol polyoxyethylene (10) ether monophosphoric acid, 3 parts of isomeric tridecyl alcohol polyoxyethylene ether (TO‑40), ten parts 0.03 parts of dialkyl mercaptan, 0.09 parts of ammonium bicarbonate, 0.35 parts of ammonium persulfate, 260 parts of deionized water, and 18 parts of ammonia water. The present invention adopts the step-by-step dropping method of pre-emulsified monomers, uses methacryloxypropyltrimethoxysilane to modify the acrylate emulsion with diacetone acrylamide as the crosslinking agent, and synthesizes acrylic acid through emulsion copolymerization. Ester‑silicone copolymer.

Description

technical field [0001] The invention relates to the technical field of formulation and preparation of a coating adhesive, in particular to a coating adhesive for heat-sensitive copy paper and a preparation method thereof. Background technique [0002] Thermal paper is specially used for printing on thermal printers and thermal fax machines. Its quality directly affects the printing quality and storage time, and even affects the service life of printers and fax machines. The coating of thermal paper contains color developer, dispersant, adhesive and other materials. Among them, the role of the adhesive is to improve the durability of the printing color, so that the printed image and text can be kept for a longer time, and it is not affected by the external environment such as temperature and humidity. [0003] There is no adhesive specially designed for thermal paper coating on the market, and some ordinary polymers such as acrylate emulsion or polyvinyl alcohol are basicall...
