Embodiment 1
[0011] Embodiment 1, a kind of polyimide dry-process spinning oil, is made up of the raw material of following proportion by weight, is made up of the raw material of following proportion by weight, 36 parts of simethicone oil, 13 parts of refined mineral oil 5 parts, 5 parts of sorbitan monooleate polyoxyethylene ether, 7 parts of lauryl phosphate diethanolamine salt, 10 parts of potassium cetyl phosphate, and 15 parts of fatty alcohol polyoxyethylene ether. Mix simethicone and refined mineral oil evenly, heat up to 40°C, add sorbitan monooleate polyoxyethylene ether, stir for 30 minutes, heat up to 60°C, add cetyl potassium phosphate and fatty alcohol Stir polyoxyethylene ether for 20 minutes, cool down to 40°C, add dodecyl phosphate diethanolamine salt, continue stirring for 40 minutes, then cool to 25°C to obtain polyimide dry spinning oil.
[0012] Embodiment 1 is compared with the polyimide dry spinning oil agent imported from Japan, and the measured data of the oil agen...

Abstract
The invention relates to a dry-process polyimide spinning oil which is prepared from the following raw materials in parts by weight: 30 to 60 parts of simethicone, 10 to 30 parts of refined mineral oil, 3 to 9 parts of sorbitan tristearate polyoxyethylene ether, 5 to 10 parts of dodecyl phosphate diethanolamine salt, 8 to 14 parts of hexadecyl potassium phosphate and 10 to 20 parts of fatty alcohol-polyoxyethylene ether. The dry-process polyimide spinning oil prepared from the simethicone, the refined mineral oil, sorbitan tristearate polyoxyethylene ether, the dodecyl phosphate diethanolamine salt, hexadecyl potassium phosphate and fatty alcohol-polyoxyethylene ether is reasonable in formula, good in application effect and low in production cost; and in addition, the problems that fibers cannot be easily unwound and fiber bundles cannot be well gathered due to large static electricity among the fibers and the like are solved well.
Description
technical field [0001] The invention relates to a spinning finish, in particular to a polyimide dry spinning finish. Background technique [0002] Polyimide fiber has excellent thermal stability, radiation resistance, non-combustibility, and good mechanical properties. It can be used for a long time under extremely harsh environmental conditions such as high temperature, radiation, and high corrosion. Since the 1990s, It is increasingly widely used in high-temperature filter materials. [0003] At present, the production of polyimide fiber is mainly concentrated in foreign countries and the process route is wet spinning. The polyimide fiber produced by dry process is the first development at home and abroad, and it is still in the initial stage of development and production. There is no special purpose in China. spinning finish. Therefore, there is an urgent need to develop a polyimide dry spinning finish with low production cost, excellent antistatic properties and stable...
