Abstract

The invention belongs to the field of thermo-sensitive paper, particularly relates to a preparation method of a composite hollow reflecting layer. According to the invention, polypropylene hollow microspheres are used as hollow spheres and polyfunctional polyhedral oligomeric silsesquioxane is used as an adhesive connecting agent to form the composite hollow reflecting layer; and the preparation method is also provided. The problems that the heat stability of the surface of the reflecting layer is poor and printing ink is prone to being gelatinized are solved, a cage type frame structure of the cage type polysilsesquioxane is utilized, side face loss of heat is reduced, and the definition of the printing ink is improved.

Description

technical field [0001] The invention belongs to the field of heat-sensitive paper, and in particular relates to a preparation method of a composite hollow reflective layer. Background technique [0002] Thermal paper is widely used in food, logistics, lottery, medical and other industries in China. The printing principle of thermal paper is that the leuco dye is converted into a colored dye through the transfer of heat. In order to make full use of heat, thermal paper will use heat insulating material to ensure the effective use of heat, so as to ensure the fineness of printing. At present, ordinary hollow ball insulation material is used for heat utilization in the bottom layer, but the thermal stability of the surface of the reflective layer is poor, resulting in blurred ink edges after printing. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a composite hollow reflective layer, which solves the problem of poo...
