Problems solved by technology

However, its poor flame retardant performance affects its scope of use. With the increase of society's requirements for flame retardant materials, its flame retardant modification has always been a hot spot.
At the same time, although polyester melt droplets can take away part of the heat from the polymer substrate, which is beneficial to the flame retardancy of polyester, the melt droplets have brought more serious disasters: on the one hand, the melt droplets may cause the flame to spread to other places, causing Larger fires; on the other hand, it is easy to cause secondary injuries including scalds and burns

Embodiment 1

[0021] Step 1. Fabric pretreatment: In order to have good adhesion between the flame retardant additive and the polyester fabric, the polyester fabric must be clean and free of dirt, so the polyester fabric should be pretreated before flame retardant treatment. The pretreatment solution contains sodium hydroxide, penetrant and surfactant. Put the polyester fabric into an appropriate pretreatment solution, boil it at 90°C for 30 minutes, take it out, wash it with clean water, and dry it for later use.

[0022] Step 2, preparation of flame retardant:

[0023]

[0024] Measure a certain amount of EG, and slightly excess. Add the materials into the reactor that has been washed, and react for 3 hours while maintaining the internal temperature at 150°C. Judge whether the pre-esterification is completed according to the amount of esterified water and the temperature at the top of the fractionating column; a certain amount of PTA, stabilizer TMP, toner Co(CH 3 COO) 2 4H2O, poly...

[0034]

[0035]

[0036] Measure a certain amount of EG, and slightly excess. Add the materials into the reactor that has been washed, and react for 3 hours while maintaining the internal temperature at 150°C. According to the amount of esterified water and the temperature at the top of the fractionating column, it is judged whether the pre-esterification is completed; after the pre-esterification is completed, a certain a...

Embodiment 3

[0044] Step 1. Fabric pretreatment: In order to have good adhesion between the flame retardant additive and the polyester fabric, the polyester fabric must be clean and free of dirt, so the polyester fabric should be pretreated before flame retardant treatment. The pretreatment solution contains sodium hydroxide, penetrant and surfactant. Put the polyester fabric into an appropriate pretreatment solution, boil it at 90°C for 30 minutes, take it out, wash it with clean water, and dry it for later use.

[0045] Step 2, preparation of flame retardant:

[0046]

[0047] Measure a certain amount of EG, and slightly excess. Add the materials into the reactor that has been washed, and react for 3 hours while maintaining the internal temperature at 150°C. Judge whether the pre-esterification is completed according to the amount of esterified water and the temperature at the top of the fractionating column; a certain amount of PTA, stabilizer TMP, toner Co(CH 3 COO) 2 4H2O, poly...

Abstract

The invention relates to the technical field of functional fiber production, in particular to a flame retardant and a method for preparing flame-retardant polyester by using the flame retardant. The flame-retardant polyester is prepared through the steps of fabric pretreatment, flame retardant preparation, a padding process and a coating process. The flame retardant is prepared from 10-20 parts ofPET, 5-10 parts of CEPPA, 10-20 parts of EG, 5-10 parts of PTA, 2-5 parts of TMP, 3-6 parts of Sb2O3, 6-10 parts of Co(CH3COO)2.4H2O, 2-5 parts of GMA, 2-5 parts of BP, 5-10 parts of NaOH and 5-20 parts of CH3COCH3. Compared with the prior art, the method has the advantages that the operation is simple, the requirement on the proficiency degree of personnel operation is not high, the labor cost is saved, and the flame-retardant polyester fabric has a self-extinguishing effect, is green and environment-friendly, small in environment pollution, incapable of producing molten drips at high temperature and incapable of causing secondary damage.

Description

technical field [0001] The invention relates to the technical field of functional fiber production, in particular to a flame retardant and a method for preparing flame retardant polyester by using the flame retardant. Background technique [0002] With the advancement of human civilization and the rapid development of society, the factors that induce fires are also increasing, the frequency of fires is also increasing, and the consequences of fires are more serious, causing more and more harm to human society. At present, more than 20,000 fires occur every day on average in the world, and nearly 1,000 people die in fires every day on average. According to statistics, the average annual fire loss in my country in the 1970s was less than 250 million yuan, and the average annual fire loss in the 1980s was less than 320 million yuan. In the 1990s, especially since 1993, about 40,000 fires have occurred in my country every year, killing more than 2,000 people and injuring 3,000-...
