Cinnamic acid: polycaprolactam "fire" without burning
Polycaprolactam has excellent and balanced mechanical properties and is suitable for various processing methods such as spinning, injection molding, extrusion, and blow molding. It is widely used in the fields of synthetic fibers and engineering plastics. It is mainly used to manufacture tire cords, fishing nets, cables, and poly Caprolactam parachutes, etc., and civilian fabrics, such as clothing, socks, etc., are also widely used in the manufacture of large gears, turbines, bushings, rollers, rings, gaskets, universal joint shaft sliders, etc. Performance of mechanical parts, as well as oil storage tanks.
Polycaprolactam has poor flame retardancy and often requires the addition of flame retardant additives. In particular, polycaprolactam has good fluidity in the molten state, but the polycaprolactam fluidity needs to be further improved in order to produce some products having a complicated shape or thin walls. More importantly, polycaprolactam is a polar polymer and has strong adhesion to metals. Polycaprolactam containing no lubricant can make it difficult to release the product. Therefore, injection grade polycaprolactam special materials contain lubricant/release agent. However, the key to the selection of polycaprolactam lubricant is how to achieve the desired lubrication/demolition effect while avoiding the adverse effects of lubricants on other important properties of polycaprolactam such as non-flammability.
Higher fatty alcohols, higher fatty acids and their esters are very effective for mold release. Adding about 0.2% will reduce the flame retardancy of polycaprolactam from UL94 (flammability rating test)-V2 to HB, which cannot meet the flame retardancy of polyamide products. The most basic requirement of sex. An effective way to solve this type of problem is to avoid the use of a single type of lubricant. After continuous research, the experts found that stearyl-zinc stearate-cinnamic acid tri-component lubricant was used to increase the flame retardancy from UL94-V2 to V1 while maintaining the effect of stearyl alcohol release. In addition, the melting point of the combination lubricant is only about 100°C, and the fluidity in the molten state is good.
Experts further found that the addition of cinnamic acid as a flame-retardant additive to polycaprolactam also greatly improves the flame-retardant properties of polycaprolactam. In the words of a marketing expert, the polycaprolactam products with cinnamic acid-based flame retardant additives will be more popular with consumers, and sales will be even more fiery.
