Abstract

The invention relates to a method for preparing flame-retardant luminous polyethylene glycol terephthalate. The flame-retardant luminous polyethylene glycol terephthalate is prepared from 0.1 to 20 weight percent of radiant agent, 0.1 to 20 weight percent of fire retardant and the balance of the polyethylene glycol terephthalate, wherein in an esterification reaction, the temperature is between 200 and 290 DEG C and the pressure is between 0.1 and 0.5 MPa; in a low-vacuum polycondensation reaction, the temperature is between 200 and 290 DEG C and the pressure is between 500 and 100,000 Pa; in a high-vacuum polycondensation reaction, the temperature is between 250 and 300 DEG C and the pressure is between 50 and 500Pa; the radiant agent accounts for 5 to 30 percent of the weight of slurry; the grain diameter of the radiant agent is between 1 nm and 1 micron; and the radiant agent with the grain diameter more than 760 nm accounts for 5 percent of the total weight of the radiant agent. The fiber fabric of the flame-retardant luminous polyethylene glycol terephthalate prepared from the composite materials has fire-retardant and luminous effects and is used for fire-fighting working clothes, marine working clothes and camping tents.

Description

Technical field: [0001] The invention relates to a polyethylene terephthalate (PET) composite material, in particular to a PET composite material with flame-retardant and luminescent effects and a preparation method which is composited by PET, a luminescent agent and a flame retardant. Background technique: [0002] Since the industrialization of polyethylene terephthalate fiber in the early 1950s, it has been favored by people in the textile industry for its excellent properties such as high modulus, good resilience, good light resistance, good wear resistance, and good heat resistance. The favor of consumers and the welcome of consumers, the application field is constantly expanding, and the demand is gradually increasing. The widespread use of synthetic fibers has played an important role in the development of the national economy, but its flammability has brought serious harm to human society. Therefore, the production of flame-retardant textiles to prevent fires has be...
