Problems solved by technology

[0004] The inventors of the present invention have found in the long-term research and development process that when the thermal paper printing environment (such as temperature, printing length, etc.) changes, some chemical substances (such as leuco dyes, Color developer, etc.) will accumulate on the print head of the thermal printer, and in severe cases, it will cause damage to the print head and reduce the service life of the thermal printer

Embodiment 1

[0027] A. Provide the original base paper;

[0028] B. Preparation of heat-sensitive paper primer coating solution: under high-speed stirring conditions, mix 82g of light calcium carbonate, plastic pigment and silicon dioxide with a mass ratio of 2:2:1, 18g of polyvinyl alcohol, and 257g of water Mix evenly, thereby the quality that obtains primer coating accounts for the primer coating solution that the total mass of primer coating solution is 28%;

[0029] C. Using a coating machine, apply 7.2g / m on the surface of base paper 2 The coating amount of the primer coating solution is applied, and the primer layer is formed after drying;

[0030] D. Preparation of heat-sensitive paper surface coating solution: (1) Preparation of the first mixed solution: 40 g of 2,4 diphenylsulfone phenol, 4.5 g of polyvinyl alcohol, and 67 g of water are mixed to prepare the first mixed solution with a mass fraction of 40%. A mixed solution, and then ground in a wet grinder until the solid part...

Embodiment 2

[0033] A. Provide the original base paper;

[0034] B. Preparation of heat-sensitive paper primer coating solution: under high-speed stirring conditions, mix 90 g of a mixture of calcined kaolin and plastic pigments with a mass ratio of 1:1, 10 g of polyvinyl alcohol, and 213 g of water to obtain a primer layer The quality of the paint accounts for the primer coating solution that is 32% of the total mass of the primer coating solution;

[0035] C. Using a coating machine, apply 8.0g / m on the surface of base paper 2 The coating amount of the primer coating solution is applied, and the primer layer is formed after drying;

Abstract

The invention discloses a heat sensitive paper top coating paint, a heat sensitive paper paint and a heat sensitive paper. The heat sensitive paper top coating paint comprises a first filler, wherein the first filler comprises light calcium carbonate of which the oil absorption value is greater than or equal to a threshold. According to the above manner, the embodiments provided by the invention can relieve the accumulation of printing heads of a thermal printer when the heat sensitive paper printing environment is changed.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a heat-sensitive paper surface coating paint, heat-sensitive paper paint and heat-sensitive paper. Background technique [0002] In recent years, the use of thermal paper has become more and more extensive, and the demand for use has also increased year by year. From common cash register receipts, freight logistics labels, food labels and metering labels for different applications in supermarkets, to transportation bills, lottery paper for high-end applications, etc., hot paper can be seen in more and more places. Use of sensitive paper. [0003] When printing on thermal paper, you need to use the matching thermal printer. The working principle of the thermal printer is: the printing head of the thermal printer is equipped with a heating element. When the heating element passes a certain current, it will quickly generate high temperature. When the top coat of the paper meet...
