| Abstract: |
| In order to solve the difficulty of cleaning membrane, high cost and strict requirement to environment for traditional coating, one kind of solvent strippable plastic was developed. This product not only is easy to strip, lowcost, without special requirement to the environment, but also has fine mechanical property and antiseptic property. Ethyl cellulose was used as the main film-forming material. Other ingredients, such as the auxiliary film-forming material, inhibitor, water-repellent, solvent and so on, were joined. The formulation was optimized through the orthogonal experiment. Tensile property experiment and rust preventing ability test were used separately to research the properties of solvent strippable plastic. The experiment indicates the following points Firstly, the strippable plastics have excellent tensile property, its tensile-strength reaches as high as 16. 3MPa; Secondly, the strippable plastics have the excellent rust resistance, the low-carbon steel and pure aluminum are sepatately placed for 472h, 528h and have not presented rust in the process of salt spray test; After being soaked separately in the running water for 480h, 5% H2S04 for 367h, 5% NaOH for 486h and 3% Nacl for 402h, the test piece has not presented the corrosion phenomena. |
