Problems solved by technology

[0004] The above scheme has the following defects: aluminum hydroxide, magnesium hydroxide and zinc borate all achieve flame retardant effects by forming glass bodies after hot melting for oxygen and heat insulation, that is, flame retardant is achieved through the condensed phase flame retardant mechanism, but the fiber The mechanism of combustion is extremely complicated. It is difficult to block the combustion process from the chain reaction of the essence of combustion, so that the smoldering time and the degree of fiber damage are relatively large.

Embodiment 1

[0040] Embodiment 1: A kind of flame-retardant polyester mother silk,

[0041] It is prepared from polyester fiber masterbatch and 2,4,6-tribromophenyl zinc borate. The polyester fiber masterbatch is polyethylene terephthalate masterbatch, 2,4,6-tribromophenyl zinc borate is made from 2,4,6-tribromophenylboronic acid and zinc oxide, 2,4 , The mass ratio of 6-tribromophenylboronic acid to zinc oxide is 3:1. The specific components and their corresponding dosages used in the flame-retardant polyester mother silk are shown in Table 1.

[0042] The above-mentioned flame-retardant polyester mother silk is prepared by the following process:

[0043]S1: Weigh 15kg of 2,4,6-tribromophenylboronic acid and dissolve it in 8L of ethanol, then add 5kg of zinc oxide to the system, heat at 95°C and condense to reflux, react for 10 hours and filter while hot A solid crystal was obtained, which was washed with water to obtain 2,4,6-tribromophenyl zinc borate.

[0044] S2: Weigh the amount ...

Embodiment 2-5

[0047] Embodiment 2-5: a kind of flame-retardant polyester mother silk,

[0048] The difference from Example 1 is that the amounts of polyester fiber masterbatch and 2,4,6-tribromophenyl zinc borate are different, and the specific amounts are shown in Table 1 below.

Embodiment 6

[0049] Embodiment 6: A kind of flame-retardant polyester mother silk,

[0050] The difference from Example 1 is that the raw material also includes 40 kg of phosphoric acid ester, and the phosphoric acid ester is specifically selected from tricresyl phosphate.

[0051] Prepared by the following process:

[0052] S1: Weigh 15kg of 2,4,6-tribromophenylboronic acid and dissolve it in 8L of ethanol, then add 5kg of zinc oxide to the system, heat at 95°C and condense to reflux, react for 10 hours and filter while hot Obtain solid crystals, and obtain 2,4,6-tribromophenyl zinc borate after washing with water;

[0053] S2: Weigh the amount of 2,4,6-tribromophenyl zinc borate in Table 1, mix it with polyethylene terephthalate masterbatch in a stirring tank, and then send the mixture into the screw for extrusion In the machine, the mixture is heated and melted at a temperature of 300°C;

[0054] S3: Spinning the melt-mixed mixture through a spinneret, and obtaining primary fibers af...

Abstract

The invention relates to the technical field of spinning, and particularly discloses flame-retardant terylene main yarn and a preparation process thereof. The flame-retardant terylene main yarn is mainly prepared from the following raw materials in parts by mass of 40-50 parts of polyester fiber master batch, 3-8 parts of 2, 4, 6-tribromo phenyl zinc borate, 30-50 parts of phosphate ester and 0.5-1 part of a penetrant. The preparation process of the flame-retardant terylene main yarn comprises the following steps of carrying out melt blending on a flame-retardant alloying agent and the polyester fiber master batch, carrying out extrusion spinning to obtain nascent fibers, and carrying out after-treatment on the nascent fibers by using the phosphate ester and the penetrant to obtain the flame-retardant terylene main yarn. The flame-retardant terylene main yarn provided by the invention can perform flame retardance from a condensed phase and a gas phase in various modes during combustion, and has an excellent flame-retardant effect.

Description

technical field [0001] The present application relates to the technical field of spinning, in particular to a flame-retardant polyester mother filament and a preparation process thereof. Background technique [0002] Flame-retardant fiber, also known as flame-retardant fiber, refers to the fiber that only smolders in the flame, does not generate flame itself, and smolders and extinguishes itself when it leaves the flame. It is widely used in clothing, home furnishing, decoration, non-woven fabrics and fillings. [0003] For example, a Chinese patent with the authorized announcement number CN101265620B discloses a blended flame-retardant polyester industrial filament and its production process. The blended flame-retardant polyester industrial filament contains flame retardant masterbatches, flame retardant masterbatch The mass percentage distribution of granules and polyester masterbatches is as follows: polyethylene terephthalate: 90-95%; inorganic flame retardant masterbatc...
