Abstract
The invention discloses a photosensitized oxidation delible ink composite. The composite mainly comprises the following components by weight percent: 3-6% of pigment, 40% of ethanol, 50% of water, 0.1% of CMC, 0.05% of APG, 0.05% of OP-10, 2-3% of glycerin, 0.1-1% of photosensitizer, 0.01% of preservative, 0.1-5% of fading resistant agent and a small amount of essence. The product of the invention is suitable for the ink used in whiteboard teachings and the writing practices of children. The photosensitized oxidation delible ink composite has the following characteristics: 1) the plant pigment is used as the main raw material for color development and is environmentally friendly and nontoxic, the dosage of the solid substance is low so that the dust pollution is hardly caused; 2) the ink can fade to colourless through photocatalytic oxidation so that children can write again without erasing, the ink has three colors, namely blue, purple and red; 3) the ink can fade in 1 minute, 5 minutes, 10 minutes, 30 minutes and one hour according to needs; and 4) the ink can be erased with water and fade to be a colorless substance.
Description
Affiliated technical field
The present invention relates to a kind of Photosensitized oxidation delible ink composite, be especially applicable to blank teaching and children's writing practising ink.
Background technology
Along with the development of multimedia teaching, as the supplementary white board marker of multimedia teaching, replace chalk to become writing implement conventional in teaching.Universal along with white board marker application, the performance of white board pen ink is also being updated and perfect.But because white board pen ink is black alcohol dissolubility ink, its composition mostly is organic amine compound and adheres on hand and have injury to be difficult for again washing off to skin, while clashing, have equally that dust pollutes the environment and teachers and students healthy.So skin easily clashes again and the white board pen ink of environmental protection becomes important research direction to study a kind of novel not injuring.
Summary of the invention
The present invention adopts the main color development raw material of the modified rear conduct of pigment extracting from the plants such as purple perilla, develops a kind of novel photosensitized oxidation fading ink, mainly contains indigo plant, purple, red three kinds of colors, can be used for pen for White board pen for teaching and children's writing practising.Novel photosensitized oxidation fading ink can self-discoloration under photochemical catalysis and air oxidation, need not clash and can write again.Its coloured material can be oxidized to colourless, nontoxic material, and its consumption is less does not almost have dust pollution.When water clashes, also can take off for colorless substance, clean, convenient, environmental protection again, be comparatively desirable blank ink.
The feature of Photosensitized oxidation delible ink composite of the present invention is: one, adopting plant pigments is main color development raw material environment-protecting asepsis, and solids consumption is less does not almost have dust pollution; Two, ink can photochemical catalytic oxidation takes off and can write for colourless need not clashing again, and has indigo plant, purple, red three kinds of colors; Three, can in 1 minute, 5 minutes, 10 minutes, 30 minutes and individual hour, fade as required; When four, water clashes, also can take off for colorless substance.
For achieving the above object, Photosensitized oxidation delible ink composite of the present invention, said composition is composed of the following components by mass percentage:
The step of preparation Photosensitized oxidation delible ink composite of the present invention is:
After adding dissolution with solvents in color development raw material, add respectively the more various auxiliary agents such as membrane-forming agent, tensio-active agent, sanitas, photosensitizers, spices.The add-on of research anti-fading agent, controls photosensitive fading time according to actual needs.Add wherein the anti-fading agent of different amounts to control fading time, can make the photosensitized oxidation fading ink fading in 1 minute, 5 minutes, 10 minutes, 30 minutes and one hour.
Embodiment
Below by embodiment, further illustrate the present invention.
Embodiment 1 blue ink composition of the present invention, said composition is composed of the following components by mass percentage:
Embodiment 2 purple composition for ink of the present invention, said composition is composed of the following components by mass percentage:
