Embodiment 1

[0041] A kind of scratch-resistant thermal paper, its manufacturing steps are as follows:

[0042] (1) The composition and preparation method of the pre-coat:

[0043] 100 parts of light calcium carbonate and 20 parts of styrene-butadiene latex are mixed under high-speed stirring to form a coating solution with a solid content of 30%; use a coating machine to coat the base paper layer, and the coating amount is 9g / m 2 ;

[0044] (2) Preparation components and production methods of the chromogenic layer:

[0045] Component A: 40 parts of oxidant bisphenol A, 3 parts of polyvinyl alcohol, mixed to prepare a mixed solution with a concentration of 40%, and ground to a mixed solution of 0.3 to 1.5 microns in a wet grinder;

[0046] Component B: 40 parts of sensitizer 1, 2-diphenoxyethane, 3 parts of polyvinyl alcohol, mixed to prepare a mixed solution with a concentration of 35%, and ground to a mixed solution of 0.2-1.7 microns in a wet grinder;

[0047] Component C: 40 parts o...

Embodiment 2

[0053] A method for manufacturing scratch-resistant thermal paper, the steps are as follows:

[0054] (1) The composition and preparation method of the pre-coat:

[0055] A filler silica, 100 parts of calcined kaolin, and A adhesive styrene acrylic resin 25 parts are mixed under high-speed stirring to form a coating solution with a solid content of 40%; use a coater to coat the base paper layer, and the coating amount 9g / m 2 ;

Abstract

The invention discloses an anti-scraping thermo-sensitive paper which comprises a raw paper layer, a pre-coating layer, a coloring layer, an anti-scraping layer and a protecting layer, wherein the raw paper layer, the raw paper layer is coated with the pre-coating layer, the coloring layer, the anti-scraping layer and the protecting layer. The invention provides a manufacturing method for the anti-scraping thermo-sensitive paper. The thermo-sensitive paper provided by the invention has the anti-scraping layer, so that the thermo-sensitive paper is not colored under the condition of repeated scraping with external force and the interference on normal word identification caused by unnecessary image-text shown due to the scraping with external force is avoided.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a scratch-resistant thermal paper. Background technique [0002] Recently, the use of thermal paper has become more and more widespread, especially in the increasingly developed logistics industry. With the advantages of convenience, speed and high utilization rate, thermal paper is gradually replacing carbonless copying paper and becoming the mainstream of the market. At present, the quality of conventional thermal label paper generally focuses on printing performance and storage performance, and less attention is paid to the scratch resistance of paper. However, as a logistics label, objects will inevitably collide and rub during the delivery process. If the paper is not scratch-resistant, it will develop color after the heat-sensitive surface is scratched, and the graphics and barcode information cannot be recognized. , affecting the normal distribution of logistics. ...
