preparation example Construction

[0029] This embodiment provides a method for preparing durable flame-retardant graphene nylon fibers. Adding graphene to the flame-retardant coating can, on the one hand, adjust the viscosity of the system and improve the binding force between the inorganic flame retardant and the fiber. On the other hand, it improves the flame retardant effect of the fiber and also has an antistatic effect. The specific steps are as follows:

[0030] Step 1: Evenly mix 1-5 parts by weight of graphene, 5-10 parts by weight of flame retardant, 1-5 parts by weight of titanium dioxide, and 10-50 parts by weight of solvent, wherein figure 1 SEM image of graphene, figure 2 It is the scanning electron microscope image of titanium dioxide;

[0031] Step 2: Place the uniformly mixed raw materials in a mixing device, and add 10 to 50 parts by weight of epoxy resin to stir and disperse for 30 to 60 minutes to obtain a graphene composite flame retardant coating, such as image 3 SEM for flame retardan...

Embodiment 1

[0047] The preparation method of nylon fiber in the present embodiment, concrete steps are as follows:

[0048] Step 1: Evenly mix 5 parts by weight of graphene, 5 parts by weight of flame retardant, 3 parts by weight of titanium dioxide, and 30 parts by weight of solvent;

[0049] Step 2: Place the uniformly mixed raw materials in a ball mill, and add 10 parts by weight of epoxy resin to stir and disperse for 30 minutes to obtain a graphene composite flame-retardant coating, wherein the ball mill speed is 350rpm, and the ball-to-material ratio is 80:1;

[0050] Step 3: Dip the nylon fiber monofilament into the graphene composite coating, and pull it at a speed of 3m / s;

[0051] Step 4: Place the graphene flame-retardant composite fiber obtained in step 3 in a drying room to dry at a drying temperature of 130-160°C, then stretch and set it at a setting temperature of 190-240°C to obtain the required durable flame-retardant graphene nylon fiber.

Abstract

The invention discloses a preparation method of a durable flame-retardant graphene nylon fiber, which belongs to the field of fiber production and comprises the following steps: 1-5 parts by weight of graphene, 5-10 parts by weight of a flame retardant, 1-5 parts by weight of titanium White powder and 10-50 parts by weight of solvent are uniformly mixed; the uniformly mixed raw materials are placed in a mixing device, and 10-50 parts by weight of epoxy resin are added to stir and disperse for 30-60 minutes to obtain a graphene composite flame-retardant coating; nylon The fiber monofilament is immersed in the graphene composite coating and pulled at a speed of 1-3m / s; the graphene flame-retardant composite fiber obtained in step 3 is placed in a drying room for drying at a drying temperature of 130-160°C, and then stretched and shaped , and the setting temperature is 190-240°C to obtain the required durable flame-retardant graphene nylon fiber. The beneficial effects of the present invention are: by adding an appropriate amount of graphene into the coating, controlling the ratio of the three raw materials of graphite flame, flame retardant and titanium dioxide, effectively controlling the viscosity of the coating system and improving the binding force between the flame retardant and the fiber .

Description

technical field [0001] The invention relates to the field of fiber production, in particular to a preparation method of durable flame-retardant graphite-fired nylon fiber. Background technique [0002] The use of textiles is one of the important factors that constitute a fire threat. Treating textiles with flame-retardant methods is an important measure to reduce the risk of fire. Formulating timely, feasible and strict technical specifications is an important means to ensure the implementation of flame retardant measures. Combined with the flame-retardant requirements of textiles, the development and production of flame-retardant, low-smoke, and excellent flame-retardant protective equipment and supplies, and the strengthening of fire safety supervision and management can fundamentally prevent the fire threat of textiles and provide safety guarantees for people's lives and property. [0003] Graphene is a single-layer graphite sheet exfoliated from graphite. It has a two-...
