Abstract

The invention provides a safe, healthy and environmentally-friendly conductive ink and a preparation method thereof. The conductive ink comprises, by weight, 5-20 parts of conductive carbon black, 30-40 parts of a natural polymeric water-based ink binder, 30-40 parts of water, 0-0.5 part of a humectant and 0-0.5 part of a preservative. The natural polymeric water-based ink binder and water are adopted as main components of the conductive ink, so the safety and the environmental protection of the conductive ink are ensured, the production cost of the conductive ink is reduced, and a problem that existing conductive inks cannot be applied to teaching as a teaching aid due to toxic components and high cost is effectively solved.

Description

technical field [0001] The invention relates to a safe, healthy and environment-friendly conductive ink and a preparation method thereof, in particular to a conductive ink used in classroom teaching and a preparation method thereof. Background technique [0002] Conductive ink is a paste ink made of conductive materials dispersed in a binder, commonly known as paste ink. Because it contains conductive materials, it has a certain degree of conductive properties and is widely used in industry. It is often used to print conductive points or conductive lines. However, conductive ink contains many components, and contains a large amount of toxic and harmful substances. At the same time, the production cost is high, and it is not suitable for physics teaching demonstrations and related experiments in schools that are used as teaching aids. Contents of the invention [0003] The invention provides a safe, healthy and environment-friendly conductive ink and a preparation method t...
