Problems solved by technology

However, ordinary cellulose acetate butyrate mirror silver ink cannot meet the requirements of alcohol wipe resistance, and other resins need to be added to improve the alcohol wipe resistance of the ink, but it will inevitably reduce the imitation mirror effect of the ink, especially the added resin and acetic acid. When the compatibility of cellulose butyrate is not good, the imitation mirror effect of the ink will drop significantly
In addition, the direct mixing of cellulose acetate butyrate and acrylic resin will lead to poor cohesion of the paint film, resulting in a decrease in the alcohol wipe resistance of the paint film

The preparation method of the invention is simple, the condition is mild, the cost is low, and it is convenient for large-scale industrial production.

Description

technical field [0001] The invention relates to an alcohol-washing-resistant and high-temperature-resistant mirror silver resin and a preparation method thereof. Background technique [0002] Nitrocellulose and cellulose acetate butyrate have a good positioning effect of aluminum powder, which can make the aluminum powder particles regularly arranged in the paint film. Therefore, the imitation mirror ink made of nitrocellulose and cellulose acetate butyrate has good light reflectivity. These inks are usually used on various plastic hardware and electrical devices, and have good appearance effects. [0003] In some special occasions, the ink is also required to have alcohol wiping resistance and high temperature resistance. Since nitrocellulose will turn yellow at high temperature, and cellulose acetate can withstand high temperature, so the imitation mirror resin with high temperature resistance is usually Cellulose acetate modified resin. However, ordinary cellulose acet...
