Problems solved by technology

[0004] However, this kind of thermal paper has a common problem that most thermal printing papers have: poor color durability
Whether it is sunlight exposure during storage and transportation or sunlight exposure after printing and color development, it is easy to cause the problem of unclear color development or fading, which limits the use of this type of thermal paper

Abstract

The invention discloses sun-proof bacterium-inhibition thermo-sensitive paper. According to the technical scheme, the paper is characterized by comprising a raw paper layer, a thermosensitive color-change layer and a protection layer, the thermosensitive color-change layer is clamped between the raw paper layer and the protection layer, and sun-proof bacterium-inhibition layers are arranged on thefront and reverse faces of the raw paper layer; each sun-proof bacterium-inhibition layer is prepared from, by weight, 80-100 parts of an acrylate adhesive, 30-40 parts of a nano inorganic filler, 50-60 parts of an organic solvent, 5-8 parts of a sun-screening agent, 1-5 parts of an aloe extraction solution, 1-5 parts of an antioxidant and 1-3 parts of beewax; the organic solvent capable of dissolving beewax is selected as the solvent. The thermo-sensitive paper has the advantages of being excellent in sun-proof performance, capable of achieving a durable color after color development, good in bacterium-inhibition performance and wide in application range. The invention further correspondingly discloses a preparation method of the thermo-sensitive paper.

Description

technical field [0001] The invention relates to the technical field of heat-sensitive paper and its preparation, more specifically, it relates to a light-fast and antibacterial heat-sensitive paper and a preparation method thereof. Background technique [0002] Thermal paper is also known as thermal fax paper, thermal recording paper, thermal copy paper, and thermal copy paper in Taiwan. Thermal paper is a kind of processed paper. Its manufacturing principle is to coat a layer of "heat-sensitive paint" (heat-sensitive color-changing layer) on high-quality base paper, and make the "heat-sensitive paint" develop color through thermal printing to form text. or pattern. [0003] In the prior art, the authorized notification number is CN203487413U, which discloses a heat-sensitive paper, which includes a base paper and a heat-sensitive coating applied to the front of the base paper. The reverse side of the base paper is evenly coated with a paint layer, so that the front and bac...
