Embodiment 1

[0021] A waterproof and environment-friendly ink prepared from the following raw materials in parts by weight: 100 parts of fermented liquid, 10 parts of carbon black, 0.5 part of γ-polyglutamic acid, 2 parts of sodium secondary alkylsulfonate, and 0.5 part of musk;

[0022] Described fermented liquid is prepared by following steps:

[0023] 1) inserting Aureobasidium pullulans on the slant of PDA medium, and culturing at a constant temperature of 28° C. for 6 hours to obtain activated Aureobasidium pullulans;

[0024] 2) Shake flask culture: sterilize the seed medium at 115°C for 30min, and distribute it into 300mL Erlenmeyer flasks, 50ml / bottle; take a ring of activated Aureobasidium pullulans and insert it into the seed medium. Under the condition of rotating speed of 170r / min, the shaker was cultivated for 12h to obtain the seed solution;

[0025] The composition of the seed medium is: potato 200g / L, glucose 20g / L, pH 7.0.

[0026] 3) Fermentation culture: Sterilize the ...

Abstract

The invention discloses waterproof and environment-friendly ink which is prepared from the following raw materials in parts by weight: 100 parts of fermentation liquor, 10-20 parts of carbon black, 0.2-0.5 parts of gamma-polyglutamic acid, 0.5-2 parts of a dispersing agent and 0.5-2 parts of a preservative. The invention further discloses a preparation method of the waterproof and environment-friendly ink. The waterproof and environment-friendly ink and the preparation method thereof disclosed by the invention have the benefits that in the waterproof environment-friendly ink prepared by the invention, as the proportion of the fermentation liquid to other materials is reasonable, a large quantity of other chemical substances like a brightening agent, an adhesive, a surface active agent, a stabilizing agent, a wetting agent, a color protection agent and an oxidizing agent is reduced, so that the ink toxicity is significantly reduced, and the harm to a human body and the pollution to the environment are reduced; meanwhile, the waterproof environment-friendly ink is bright in ink trace and smooth in writing, can effectively prevent water and resist corrosion to enable the ink to keep bright and not to fade for a long term, and is low in cost, thereby being environment-friendly ink suitable for production and application.

Description

technical field [0001] This patent relates to writing materials, and relates to a waterproof and environment-friendly ink and a preparation method thereof. Background technique [0002] As one of the four treasures of the study, ink is also an essential element of calligraphy and traditional Chinese painting, which shows its importance. In the preparation process of traditional ink, a large amount of chemical substances are used to make the ink have certain toxicity, and the smell is also relatively pungent, and there will be some sediment, which will affect the fluency to a certain extent. At the same time, traditional ink often has poor water resistance, especially when soaked in rain, the handwriting will smudge, making it difficult to read. The existence of these shortcomings of traditional Chinese ink has resulted in many document records not being circulated. [0003] Aureobasidium pullulans, also known as Aureobasidium pullulans and Aureobasidium pullulans, can be u...
