Problems solved by technology

[0010] People have done a lot of work on PLA blending modification [1~4]. The use of polypropylene / polylactic acid (PP / PLA) blending can reduce the amount of polypropylene and reduce environmental pollution, and can keep the product in good condition. Mechanical properties. However, the compatibility between polar PLA and non-polar PP is poor. The literature [Carboxylated PP and PLA Blending] selected carboxylated PP and PLA blends, hoping to improve the compatibility of the two
However, the research and patents of industrialized PP / PLA blended composite materials and PP / PLA blended composite fibers have not been reported.

Abstract

The invention relates to a nano zinc oxide / polypropylene / polylactic acid composite fiber material; the components thereof comprise nano zinc oxide, polypropylene and polylactic acid, with the weight percentage of 0.1 to 20: 80 to 99.9; and the preparation thereof comprises the following steps: (1) nano zinc oxide powder is arranged in a special transmission device of a plasma treatment device for carrying out modification treatment to the nano zinc oxide powder; (2) the nano zinc oxide powder prepared by plasma treatment is mixed with polypropylene / polylactic acid powder or polypropylene / polylactic acid slices according to the proportion of 0.1 to 20 percent, a double screw extruder or a single screw extruder is used for mixing the materials, and melting mixing is carried out at 180 to 260 DEG C to obtain nano zinc oxide / polypropylene / polylactic acid composite slices; and (3) the slices are treated with spinning to obtain the nano zinc oxide / polypropylene / polylactic acid composite fiber material. The composite fibers produced by the method have good spinnability and high fiber-forming strength, and is characterized by controlled conductivity, heat conduction, antistatic and biodegradation.

Description

Technical field [0001] The invention belongs to the field of composite fibers and their preparation, and particularly relates to a nano zinc oxide / polypropylene / polylactic acid composite fiber material and a preparation method thereof. Background technique [0002] Nano-zinc oxide is a new type of high-functional fine inorganic product facing the 21st century, with a particle size ranging from 1 to 100 nanometers, also known as ultra-fine zinc oxide. Due to the miniaturization of particle size and the sharp increase in specific surface area, nano-zinc oxide produces surface effects, small size effects and macro-quantum tunneling effects that its bulk materials do not have. At the same time, it has photochemical effects and better shielding. UV performance, its UV shielding rate is as high as 98%; in addition, zinc oxide also has a series of unique properties such as antibacterial, antibacterial, deodorization, and enzyme resistance. Therefore, nano-zinc oxide has special properti...
