Problems solved by technology

[0004] However, such containers made of flocking paper generally do not have antibacterial and insecticidal capabilities, so a large number of microorganisms or small insects will adhere to the surface of the paper cup during long-term use or storage and transportation. , so as to contaminate the hands of the user, so it may also cause health problems for the user

Abstract

The invention relates to flocking paper. The flocking paper comprises a paper base layer and a thermochromic pigment layer, wherein the thermochromic pigment layer is arranged on the paper base layer, a polyurethane layer is arranged on the thermochromic pigment layer, and the thermochromic pigment layer comprises color change powder, polysiloxane, sodium dodecylbenzenesulfonate, alphadrate, silica sol, polyethylene glycol and foaming microspheres. The polyethylene glycol has good intermiscibility, so that the polyethylene glycol can contribute to enabling components to be uniformly mixed together; besides, the sodium dodecylbenzenesulfonate and the alphadrate act synergistically, so that the deinsectization and sterilization effects of the thermochromic pigment layer can be effectively improved; in addition, the foaming microspheres can be decomposed into gas in a heating process, so that bulges can be generated on the surface of the thermochromic pigment layer, and further patterns are rich in stereoscopic impression; and the polysiloxane has favorable heat insulation effects, so that a consumer is not liable to scald when using a container made from the flocking paper.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a flocking paper, a preparation method thereof and a container made thereof. Background technique [0002] With the continuous improvement of people's living standards, people's needs for paper have not only stayed on the level of writing. Because the texture of paper is generally lighter and more hygienic, people use paper to hold various foods, so various paper containers have emerged as the times require. But at the same time, new problems arise. For example, when the temperature of the thing contained in the container is too high or too low, the user cannot directly distinguish it from the appearance, thus it is easy to cause burns or frostbite to the user. [0003] Therefore, in order to enable users to quickly identify the temperature of the container, some companies have coated the outer surface of the paper with temperature-sensitive pigments with foamed microspheres, and mad...
