Abstract

The invention relates to a flame-resistant and uvioresistant polyester composite material and a method for preparing the same. The composite material is prepared by performing an esterification reaction on ethylene glycol, terephthalic acid, uvioresistant agent pulp and a flame retardant and then performing low-vacuum condensation polymerization and high-vacuum condensation polymerization, wherein the added amounts of the uvioresistant agent pulp and the flame retardant are between 0.1 and 20 weight percent and between 0.1 and 20 weight percent respectively; the esterification reaction is performed at the temperature of between 200 and 290 DEG C and under a pressure of between 0.1 and 0.6 MPa for 1 to 4 hours; the low-vacuum condensation polymerization is performed at the temperature of between 200 and 290 DEG C and under the pressure of between 100,000 and 500 Pa for 10 to 90 minutes; the high-vacuum condensation polymerization is performed at the temperature of between 250 and 300 DEG C and under the pressure of between 500 and 50 Pa for 1 to 4 hours; and the uvioresistant agent pulp consists of 5 to 30 weight percent of inorganic nano-oxide and the ethylene glycol. Flame-resistant and uvioresistant polyester fiber fabrics prepared from the material have flame resistance and uvioresistant effect.

Description

Technical field: [0001] The invention relates to a flame-retardant and anti-ultraviolet polyester composite material which is compounded with polyethylene terephthalate, an anti-ultraviolet agent and a flame retardant, and has flame-retardant and anti-ultraviolet effects, and a preparation method thereof. Background technique: [0002] Since the industrialization of polyester fiber in the early 1950s, it has been favored by people in the textile industry and consumers for its excellent properties such as high modulus, good resilience, good light resistance, good wear resistance, and good heat resistance. , the application field is expanding continuously, 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 become a serious social problem th...
