Description

Technical Field

[0001] The utility model relates to the technical field of para-aramid fibers, in particular to a reactor for para-aramid polymerization. Background Art

[0002] Para-aramid fiber is a high-performance fiber (PPTA for short) with excellent properties such as high strength and modulus, high temperature resistance, acid and alkali resistance and light weight. Its specific strength is 5-6 times that of steel wire, its specific modulus is 2-3 times that of steel wire or glass fiber, its toughness is twice that of steel wire, and its weight is only about 20% of that of steel wire. Therefore, it is widely used in civil and defense fields.

[0003] The synthesis of para-aramid fiber generally adopts highly active monomers terephthaloyl chloride (TPC) and para-phenylenediamine (PPD), which are obtained through condensation reaction. The melting point of TPC is above 80°C, and the temperature is usually kept at around 90°C, while PPD is kept at around 0°C. The polymerization of para-aramid fiber requires that terephthaloyl chloride (TPC) and para-phenylenediamine (PPD) can be mixed evenly in the shortest possible time.

[0004] The prior art patent document with publication number CN214439094U provides a mixer for para-aramid polymerization, which uses a necking port and an expansion port to limit the flow diameter of terephthaloyl chloride (TPC), so that it is accelerated and then sprayed outward evenly, and paraphenylenediamine (PPD) liquid is introduced from the bottom to make it flow evenly inward in the form of overflow to mix.

[0005] Although the above-mentioned prior art allows the accelerated terephthaloyl chloride (TPC) to impact the overflowing p-phenylenediamine (PPD) liquid for preliminary mixing, some of the liquids are still not mixed evenly, and the preliminary mixed liquids cannot be secondary mixed in a short time, which cannot meet people's needs. Therefore, we need a reactor for para-aramid polymerization. Utility Model Content
