Waterproof electronic paper and making method thereof

The invention discloses a piece of waterproof electronic paper. The waterproof electronic paper comprises electronic paper, a waterproof coating and an electronic paper substrate, wherein the electronic paper substrate has the shape same as that of the electronic paper; the electronic paper substrate is of a box body structure; the upper end of the box body is open; the electronic paper is arranged in a cavity of the box body; the cavity of the box body is filled with the waterproof coating. The waterproof electronic paper has the technical effects that the electronic paper product is excellent in waterproof performance, the display performance of the electronic paper product cannot be influenced even if the electronic paper product is boiled at high temperature (of 100DEG C) for a long time (10 hours), and the electronic paper product can meet the strict requirement of a client on the service environment of the product. Moreover, waterproof glue selected by the invention has high transparency (the light transmittance is greater than 90 percent), is stable in chemical properties, and cannot chemically react with the electronic paper due to long-time contact with the electronic paper, and abnormal display of the electronic paper is avoided; the waterproof electronic paper is high in physical stability, and can well protect the electronic paper product against water vapor when the electronic paper product is in contact with the external environment for a long time, so that the service life of the electronic paper is greatly prolonged.
