A kind of high fade resistance polypropylene-graphene color masterbatch and preparation method thereof

Abstract

The invention discloses a polypropylene-graphene color master batch with a high fading resistance and a preparation method thereof. The raw materials of the color master batch comprise graphene oxide, polypropylene, sodium sterate, acrylamide, an antioxidant, dibutyl phthalate, calcium silicate, a promoter, N,N-dimethylethanolamine and poly(ethyleneglycol p-phthalate). The preparation method comprises firstly adding graphene oxide into water to form a suspension, then successively adding acrylamide and ethanol into the suspension, performing stirring, adding dibutyl phthalate and N,N-dimethylethanolamine, performing heating for reaction, then adding the promoter, performing boiling, steaming an obtained mixture to dry, mixing the dried material, polypropylene, sodium stearate, the antioxidant, calcium silicate and poly(ethyleneglycol p-phthalate), performing grinding, and performing extrusion granulation on the ground material, so as to obtain the polypropylene-graphene color master batch with the high fading resistance. By modifying graphene, the heat resistance, light fastness and oxidation resistance of graphene are enhanced, and also the prepared color master batch is good in dispersibility, good in color reappearance and excellent in color fading resistance.

Description

technical field [0001] The invention belongs to the technical field of synthetic fibers, and in particular relates to a high-fading-resistant polypropylene-graphene color masterbatch and a preparation method thereof. Background technique [0002] Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. Polypropylene fine denier long fibers have good luster, soft hand feeling, good drapability and low density. They are suitable for the knitting industry. Ideal material for high-end sportswear, T-shirts and more. However, due to the poor colorability and low light fastness of polypropylene, it is difficult to develop in clothing materials, and its output only accounts for about 10% of the output of polypropylene fibers, and most of them are mixed with other fibers.

Problems solved by technology

However, due to the poor colorability and light fastness of polypropylene, it is difficult to develop in clothing materials, and its output only accounts for about 10% of the output of polypropylene fibers, and most of them are mixed with other fibers.

[0003] The defect that polypropylene is not easy to color and color retention is determined by its molecular structure: first, there are no polar groups in the molecular chain, and there is no affinity for the colorant, so the relationship between the colorant and the matrix resin is only physical. Second, there are unstable tertiary carbon atoms in the molecular chain, which are easy to break bonds under the action of light, oxygen, and heat, destroying the original structure of polypropylene and colorants, resulting in fading of the product and mechanical damage. reduced performance
