Embodiment 1

[0049] The weight components of a halogen-free flame-retardant antistatic nylon 6 chip are:

[0050]

[0051]

[0052] The organophosphorous flame retardant is phosphite;

[0053] The composite antistatic agent is polyether ester amide and polyethylene oxide; the polyether ester amide:polyethylene oxide=1:2.

[0054] The stabilizer is a hindered amine stabilizer.

[0055] The preparation method of the halogen-free flame-retardant antistatic nylon 6 chip, such as figure 1 Said: The steps are as follows:

[0056] Step 010, pretreatment of hexapropionamide: vacuum-dry hexapropionamide for 1 hour, and the vacuum degree is 0.05kpa;

[0057] Step 020, adding a stabilizer to the pretreated hexapropionamide, mixing and stirring evenly to obtain a mixture a; the mixture a is placed in a reaction kettle for microwave heating, and the heating temperature is slowly heated to 200° C. for 3 hours to obtain Mixture b is cooled to room temperature; the mixture a can be heated evenly...

Embodiment 2

[0069] The difference between this embodiment and the first embodiment is that the organophosphorus flame retardant is phosphite and organophosphorus salt;

[0070] The composite antistatic agent is polyether ester amide and polyethylene oxide; the polyether ester amide:polyethylene oxide=1:3.

[0071] The stabilizer is a hypophosphite stabilizer.

Embodiment 3

[0073] The difference between this embodiment and the first and second embodiments is that the organophosphorus flame retardant is phosphite, organophosphorus salt and polymer phosphate;

[0074] The composite antistatic agent is an antistatic agent: polyether ester amide and polyethylene oxide; the polyether ester amide: polyethylene oxide = 1.5:2.

[0075] The stabilizers are hindered amine stabilizers and hypophosphite stabilizers.

Abstract

The invention provides halogen-free flame-retardant antistatic nylon 6, a preparation method of the halogen-free flame-retardant antistatic nylon 6 and a reactor for preparation of the halogen-free flame-retardant antistatic nylon 6. The halogen-free flame-retardant antistatic nylon 6 slice comprises the following components in parts by weight: 15 to 18 parts of an organophosphorus flame retardant, 1 to 2 parts of a composite antistatic agent, 3 to 5 parts of a flame retardant synergistic agent, 80 to 95 parts of hexanolactam, and 0.05 to 10 parts of a stabilizer. The upper half part of a reactor main body and a stirring zone are connected through a flange; a window is arranged in a side wall of the stirring zone; a control device is arranged on a side wall of the outer part of the reactor main body; a stirring device is arranged in the stirring zone inside the reactor main body, and comprises a reducer, a rotating shaft a and a stirring wheel; the reducer is arranged in any position outside the reactor main body; the rotating shaft a is connected with the reducer and located in a hemispherical plane part of the lower half part of the reactor, and the flame retardancy and antistatic properties of the nylon 6 slice are simultaneously improved through the centre of sphere, and can reach corresponding balance and increase the stirring area of the reactor.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a halogen-free flame-retardant antistatic nylon 6, a preparation method and a reaction kettle for preparation. Background technique [0002] Nylon 6 fiber has a series of excellent properties, but also has disadvantages, such as low modulus, poor light and heat resistance, easy aging, and poor antistatic properties. With the improvement of living standards, people are not completely satisfied with the warmth effect brought by traditional fibers, and are more pursuing functionalization, refinement, health and quality. Compared with foreign developed countries, there are very few new nylon fiber products with independent intellectual property rights in my country at present, and fewer varieties are actually used for industrialization. Secondly, the price of nylon fiber is higher than that of polyester fiber, and fiber series products must be positioned at the high-end level. , in ...
