Embodiment 1
[0017] Embodiment 1: An environmentally friendly and fade-controllable ink, including the following raw materials in parts by mass: 15 parts of pure water, 70 parts of ethanol, 20 parts of colorant, 20 parts of sodium alginate, 20 parts of sodium carbonate, 205 parts of sodium acetate, 5 parts of gum arabic, 5 parts of film forming agent, 1 part of active agent, 1 part of glycerin, 1 part of essence.
[0018] A preparation method of environmentally friendly fade controllable ink, comprising the following steps:
[0019] S1: Dissolve an appropriate amount of sodium alginate, sodium carbonate and sodium acetate in purified water, add ethanol, and stir to obtain an alkaline liquid. The preparation method of the alkaline liquid is: add sodium alginate, sodium carbonate and sodium acetate into the reaction kettle , add purified water at the same time, react in a high-speed homogenizer at 12000-14000rpm for 1-2 minutes, then add ethanol and continue stirring for 4-12 hours to obtain...

Abstract
The invention discloses a process method for preparing environment-friendly color fading controllable ink, relates to the technical field of pure cotton fabrics, and aims to solve the problem that the existing mosquito repelling pure cotton fabric in the background technology cannot keep a long-term effective mosquito repelling effect, the the following scheme is put forward: the environment-friendly color fading controllable ink is prepared from the following raw materials in parts by mass: 15-20 parts of purified water, 70-80 parts of ethanol, 20-30 parts of a coloring agent, 20-25 parts of sodium alginate, 20-25 parts of sodium carbonate, 20-25 parts of sodium acetate, 5-10 parts of Arabic gum, 5-10 parts of a film-forming agent, 1-5 parts of an active agent, 1-5 parts of glycerin and 1-5 parts of essence. When the ink is used, the aroma enhancing function of the essence can greatly reduce the smell of the original ink, so that the ink is more comfortable for people to use, and in the aspect of materials, the raw materials are simple, the cost is low, the ink is easy to prepare, the property is stable, the preparation method is simple, and the prepared ink is bright in handwriting and smooth in writing when being used; and the color can be erased and faded by using a nearly half-wet eraser or soft cloth.
Description
technical field [0001] The invention relates to the technical field of environmentally friendly inks, in particular to a process for preparing environmentally friendly and fade-controllable inks. Background technique [0002] The recycling of waste paper has increasingly become an important environmental protection topic. If the used paper can be reused, the waste of paper can be greatly reduced. In order to solve this problem, a kind of fadeable ink has been invented in the prior art. After writing on paper, it will disappear automatically within a few minutes to a few hours, which is convenient for reusing paper, and plays the role of saving and environmental protection. [0003] The existing inks that can fade and disappear have low smoothness when writing, and poor user experience. After repeated use, the fading effect is getting worse and worse, and the durability is not good. It can be seen from this that based on the deficiencies in the prior art, it is possible to p...
