| titleOfInvention | A kind of black polyamide thin film and its preparation process |
| abstract | The invention discloses a kind of black polyamide thin film and its preparation process, include the following steps：1) black paste is prepared：Surface conditioning agent is mixed with carbon black, absolute ethyl alcohol and deionized water, is stirred, baking handles to obtain the modified carbon black in surface, black paste then is made in the modified carbon black in surface and dimethylacetylamide；2) prepared by black polyamic acid resin：Black paste prepared by step 1) is added in polyamic acid resin solution, stirs and heats obtained black polyamic acid resin；3) prepared by black polyamide thin film：For the black polyamic acid resin that step 2) is obtained after defoaming, black polyamide thin film is made in salivation, stretching, high temperature imidization.Using the black polyamide thin film of modified carbon black pigment preparation, its tensile strength improves 40%, and elongation improves 30%, it is seen that light transmission rate reduces 40%. |
