Problems solved by technology

The current society pays more and more attention to safety. In the field of electronics and electronics, only good flame retardancy can no longer meet the needs of users for safety. Some users need these products to be extinguished quickly at extremely high temperatures. , and further requires no ignition, no open flame and less smoke
At present, for various reasons, developed countries such as Europe/Japan have imposed various restrictions o

Example Embodiment

[0009] The first embodiment provides a halogen-free high glow wire ignition temperature flame-retardant nylon 6, which is composed of the following ingredients in a weight ratio: nylon 6: 72.9%; halogen-free nitrogen and phosphorus flame retardant: 20%; halogen-free auxiliary resistance Burning agent: 3%; heat stabilizer: 2.5%; coupling agent: 0.3%; antioxidant: 0.6%; other additives: 0.7%.

[0010] Dry the nylon 6 at 90 degrees for 3-4 hours first, and then weigh the dried nylon 6, heat stabilizer, coupling agent, antioxidant and other additives in proportion to the mixer. Mix at medium and low speed for 10 minutes. The mixer adopts low speed mixing. The gap between the mixing blade and the cylinder wall should be less than 0.5 cm. The mixing effect of the raw and auxiliary materials should be visually consistent with all particles and powders, without obvious clumps or agglomeration; The diameter ratio twin-screw extruder is set at a speed not higher than 200 rpm under the cond...

Abstract

The invention relates to an organic macromolecular composite material, in particular to a halogen-free high glowing filament ignition temperature flame-retardant nylon 6 and a manufacturing process thereof. The flame-retardant nylon 6 consists of the following components in percentage by weight: 55 to 80 percent of nylon 6, 5 to 30 percent of halogen-free nitrogen phosphor series flame retardant, 1 to 6 percent of halogen-free auxiliary flame retardant, 1 to 5 percent of thermal stability, 0.1 to 0.9 percent of coupling agent, 0.3 to 0.8 percent of antioxidant and 0.1 to 5.5 percent of other auxiliary agents. The halogen-free high glowing filament ignition temperature flame-retardant nylon 6 and the manufacturing process thereof are characterized in that the flame-retardant nylon 6 is environment-friendly and halogen-free, increases the characteristic of high glowing filament ignition temperature based on good maintenance of comprehensive mechanical property and halogen-free fireproof flame retardancy, is convenient to produce and purchase and is produced by totally adopting domestic raw and auxiliary materials, additives and production equipment; and the production cost and the raw material cost are greatly reduced so as to effectively improve the comprehensive competitive power of flame-retardant nylon 6.

Description

technical field [0001] The invention relates to an organic polymer composite material, in particular to a halogen-free high glow wire ignition temperature flame-retardant nylon 6 and a preparation method thereof. Background technique [0002] Nylon 6 is one of the most widely used engineering plastics. Its amide group is polar and has a strong hydrogen bond in its structure, which makes nylon 6 have a high melting point and good physical and mechanical properties. And wear resistance and self-lubricating properties, these comprehensive characteristics are not available in other plastics. However, the flame retardancy of pure nylon 6 is not good enough, which limits the application of nylon 6, which in turn reduces the material selection room for design engineers in downstream industries. Therefore, research on composite flame retardant modification of nylon 6 has been carried out. The current society pays more and more attention to safety. In the field of electronics and e...
