Reason, it is difficult to directly react with tribromoneoamyl alcohol, cause it to be esterified further, and reduce the structure of functional groups of itself, it is difficult to
Ester exchange reaction is carried out with later stage esterification products；Prepared the trimesic acid methyl ester of methoxy group by methanol, utilize
Trimesic acid methyl ester and tribromoneoamyl alcohol carry out ester exchange reaction, prepare the fire retardant knot containing radical-scavenging function
Structure, in its flame retardant molecule structure, brominated amount is 45.14%, and in flame retardant molecule, benzene ring structure improves its one-tenth carbon further
Property, improve flame retardant effect, utilize the synergistic effect containing bromo functional groups and benzene ring structure, promote fire-retardant with become carbon effect, further
Strengthen thawing resistance energy；Containing the methoxy functional group that can carry out ester exchange reaction in molecule, in Exchange Ester Process, methanol is simultaneously
Little molecule, its boiling point is less than hydrone, and volatility is good, and saturated vapour pressure is far below vapour molecule, and therefore ester exchange is formed
Methanol is beneficial to the removing of polycondensation process small molecular, especially later stage segment and increases, and during viscosity increases, the removing of little molecule is tired
Difficult, it is difficult to reach segment propagation process；
Solid-phase tack producing is the main method of the high polymer preparing high molecular, passes through Solid State Tackifing Technique, it is achieved nylon is cut
The strand propagation process of sheet, simultaneously by using high temperature ester exchange reaction, enables solid-phase tack producing modifying agent faster time
Between realize ester exchange reaction, thus the thickening process of beneficially nylon, utilize fine vacuum to viscosify process simultaneously, make carboxylic in nylon molecules
Acid groups and amino carry out amide reaction, thus improve the molecular weight of nylon, the degree of polymerization of raising nylon, and due to nylon originally
The caprolactam of body residual would generally affect the molecular weight of polymer, hence with low-temperature high-vacuum technics of enhancing viscosity, increases with solid phase
Adhered modification agent and caprolactam ring-opening reaction, not only reduce content of monomer, also improve the degree of polymerization of nylon itself simultaneously, improves
Fiber and the intensity of fabric；
The preparation of second step modification of nylon fiber
Cut into slices as raw material with the modification of nylon that the first step obtains, with nano zine oxide as modifying agent, use melt blending to spin
Silk technique, uses hollow spinneret plate, extrudes through high pressure, and cross air blasting cools down, and oils, and stretches and winding prepares modification of nylon fibre
Dimension.
Modification of nylon fiber is owing to for hollow structure, therefore it has good thermal property.
The degree of hollowness of described nylon fiber is 35～45%.

3.45ppm transfers to 3.17ppm (b '), and therefore explanation tribromoneoamyl alcohol has carried out ester exchange reaction with trimesic acid methyl ester；
In collection of illustrative plates, methoxyl group own characteristic absorption peak c ' (δ is 3.89ppm), and c ' group characteristic peak correspondence hydrogen have been also detected that simultaneously
The ratio of the peak area that atom peak area is corresponding with b ' group characteristic peak is 3:1, the therefore corresponding hydrogen number ratio in functional group
For 3:1, existing tribromoneoamyl alcohol and trimesic acid methyl ester carry out the ester exchange reaction of 1:1 mol ratio；
Fig. 5 is the nuclear magnetic resonance of carbon collection of illustrative plates of prepared solid-phase tack producing modifying agent, also occurs in that tribromoneoamyl alcohol in collection of illustrative plates
The characteristic absorption peak of the flame-proof modifier of ester exchange reaction generation, wherein corresponding for d with f chemistry is carried out with trimesic acid methyl ester
Displacement respectively δ is that the feature of the methoxy functional group of trimesic acid methyl ester in 68.5ppm and 35.8ppm, and molecule is inhaled
Receipts peak yet suffers from, and correspondence chemistry peak value ratio with；The peak value ratio of the quaternary carbon atom in tribromo neopentyl oxygen ester
For 2:1, therefore illustrate that trimesic acid methyl ester and tribromoneoamyl alcohol have only carried out the reaction of 1:1.
