Embodiment 1

[0017] A plant-based ink for painting, which is made from the following ingredients in parts by weight: plant color paste 15, polyphenol grape seed oil 18.2, modified chitosan 3, water-soluble acrylic resin 8.5, trimethylolpropane 1.2, Glycerin 5, water 20.5.

[0018] Further, the method for preparing the plant color paste is: pulverizing plant raw materials to a 150-mesh sieve to obtain plant raw material powder, adding the plant raw material powder to an aqueous solution of octylphenol polyoxyethylene ether 6 times its mass, and then The aqueous solution of octylphenol polyoxyethylene ether is 10% absolute ethanol, heated to 80°C, stirred at 1500r / min for 2 hours, then pressurized to 2.5MPa, kept for 1.5 hours, and then pressure is released and vacuum is applied. Heat to 100°C, stir at 3000r / min for 40min, then filter, repeat the extraction of the filter residue 3 times, combine the filtrate 4 times, and concentrate to 30% of the original volume of the filtrate to obtain vegeta...

Abstract

The invention discloses plant based printing ink for painting, and relates to the technical field of painting ink. The printing ink is prepared from: plant color paste, polyphenol grape seed oil, modified chitosan, water soluble acrylic resin, trihydroxymethyl propane, glycerin, and water. The plant based printing ink has good painting capability, is bright in color and high in color concentration, is free of separation of an ink layer, and has excellent anti-wearing performance, is free of adhesion, can form clear and full patterns, is good in water resistance, has stable property in the presence of acid, has good softness, is heat-resistant, anti-freezing and chemical-resistant, is toxic-free and odorless, and can effectively prevent health and safety of painting students.

Description

Technical field [0001] The invention belongs to the technical field of inks, and specifically relates to a plant-based ink for painting. Background technique [0002] In order to make the painting more colorful, it is necessary to use ink to color the painting. Ink is a viscous colloidal fluid that is uniformly mixed by pigments, binders and additives and then rolled repeatedly. Most of the existing inks for student paintings are inks made of chemical pigments, and long-term use will cause greater harm to the students' bodies. How to prepare a more environmentally friendly ink to protect the health of students is a technical problem that needs to be solved. Summary of the invention [0003] The purpose of the present invention is to provide a plant-based ink for painting in view of the existing problems. [0004] The present invention is realized through the following technical solutions: [0005] A plant-based ink for painting, which is made from the following ingredients in parts ...
