Problems solved by technology

[0007] If the chemical formula of the heat-sensitive coating is unreasonable, the storage time of the printing paper will become very short. Good printing paper can be stored for 5 years after printing (at room temperature, avoiding direct sunlight), and now it can be stored for 10 years. Years of long-lasting thermal paper, but if the formulation of the thermal coating is not reasonable, it may only last for a few months

Abstract

The invention discloses a thermo-sensitive paper coating paint and a preparation method thereof and belongs to the technical field of thermo-sensitive coating and manufacturing. The thermo-sensitive paper coating paint is composed of a component A and a component B, wherein the component A is composed of, by weight part, 12-15 parts of glucose, 4-8 parts of natural liquorice essential oil, 5-8 parts of sodium bicarbonate, 12-14 parts of sodium gluconate, 4-7 parts of citric acid, 21-28 parts of calcium phosphate, 17-25 parts of talcum powder, 9-15 parts of titanium dioxide, 13-16 parts of trioctyl trimellitate and 12-20 parts of hydroxypropyl methyl cellulose. The preparation method of the thermo-sensitive paper coating paint comprises that an auxiliary detection and control integrated device in real time detects and compares the content of components of a mixture with set content of the components. The preparation method of the thermo-sensitive paper coating paint rationalizes preparation of the thermo-sensitive paper coating paint and further controls the content of the components during preparation to provide double guarantee for rationalization of the thermo-sensitive paper coating paint and accordingly greatly prolong the storage time of printed paper.

Description

technical field [0001] The invention relates to the technical field of heat-sensitive paper coatings and preparation methods thereof, and more specifically relates to a heat-sensitive paper coating coating and a preparation method thereof. Background technique [0002] Thermal paper: as a communication carrier for text and graphics on fax machines, that is, as fax paper; as recording materials in medical and measurement systems, such as electrocardiographic drawings, thermal instrument recording paper, etc.; printing paper used in Internet terminals; In terms of commercial activities, it is used to make trademarks, POS, etc., among which fax paper occupies the largest proportion. [0003] The production principle of thermal paper is to apply particle powder on the ordinary paper base, the composition is colorless dye phenol or other acidic substances, separated by thin film, under the condition of heating, the thin film melts, and the powder mixes to develop color reaction. ...
