Problems solved by technology

[0007] In view of the properties of POSS and graphene, the purpose of adding POSS and graphene to the fiber is to play the functions of POSS and graphene at the same time, but adding these two materials to the fiber separately will only play their own roles, and even hinder each other.

Abstract

The invention relates to the field of modified polypropylene fibers, in particular to a modified polypropylene fiber and a preparing method. The preparing method includes the steps that graphene oxideand sulfydryl alkylamine react, and sulfydryl-modified graphene oxide is obtained; the sulfydryl-modified graphene oxide and vinyl POSS are subjected to a sulfydryl-alkene click chemical reaction, and vinyl-POSS-modified graphene oxide is obtained; the vinyl-POSS-modified graphene oxide and alkyl sulfhydryl are subjected to a sulfydryl-alkene click chemical reaction, then the graphene oxide is reduced, and a POSS / graphene composite material is obtained; the POSS / graphene composite material is added into polypropylene granules, melting granulation is conducted, and modified polypropylene master granules are obtained; the modified polypropylene master granules and polypropylene granules are subjected to melt spinning, and the modified polypropylene fiber is obtained. The modified polypropylene fiber obtained with the method has the good conductivity, thermal conductivity, fire resistance and mechanical property, and can be applied to spinning.

Description

technical field [0001] The invention relates to the field of modified polypropylene fibers, in particular to a modified polypropylene fiber and a preparation method. Background technique [0002] Cage polysilsesquioxane, referred to as POSS, has a general structural formula (RSiO 1.5 ) n , is an inorganic core composed of silicon-oxygen skeletons connected alternately by Si-O, and the group R connected to the Si atom at its vertex is a reactive or inert group. The three-dimensional size of POSS is between 1.3nm, the distance between Si atoms is 0.5nm, and the distance between R groups is 1.5nm, which belongs to nano-compounds. POSS is often added to polymers as an additive, so that the heat resistance, mechanical properties, processability and flame retardancy of the modified polymer can be effectively improved. [0003] The Chinese invention application patent with publication number CN101724982A discloses a POSS modified polypropylene melt-blown nonwoven fabric and its ...
