PURPOSE:
To reduce the flammability of polyamide-6 products.
DESCRIPTION:
The anionic polymerization of e-caprolactam in the presence of organomodified montmorillonite leads to the formation of exfoliated nanocomposites. At the same time, a significant reduction (27-32%) of the combustibility of composite materials and a 2.5-fold increase in mechanical properties are achieved with the introduction of a smaller amount of filler (1%) compared to traditional fillers.
TECHNICAL CHARACTERISTICS:
With an effective ratio of components, e-caprolactam polymerization proceeds without an induction period and is completed in 3-4 minutes at 170 ± 5 ° C (according to the traditional technology of hydrolytic polymerization, the process lasts 16-20 hours).
Completion of the polymerization process is provided for in two options:
-
- obtaining granular material;
- receiving a finished product (blank).
ADVANTAGES:
There is no such technology in Ukraine. Similar products may be of interest to other states.
RECOMMENDED FIELD OF APPLICATION:
The developed composite materials can be used in almost all enterprises processing polyamides, as well as in enterprises producing parts from polyamides by machining a blank. These are enterprises of the aviation, shipbuilding, electrical, machine-building, food industries, instrument making, automobile and railway transport, civil and industrial construction, agriculture.
RESULTS OF THE RESEARCH:
Provides consistent results.
STAGE OF THE DEVELOPMENT READINESS:
Tested in trial operation.
TRANSFER OPPORTUNITY:
Collaborative industrialization.
NOVELTY:
1 patent of Ukraine.
