Abstract

The invention relates to a PP-PA6 (polypropylene-polyamide 6) polymer alloy resin for spinning. A PP molecular chain and maleic anhydride molecular grafting process is adopted. As the maleic anhydride is prepared into a polymer, a solvent does not need to be used a carrier in the grafting reaction. The PP-PA6 polymer alloy resin is prepared from the following raw materials in percentage by weight: 1.2 to 1.8% of PP molecular chain and maleic anhydride molecular grafting polymer, 0.035 to 0.06% of initiator, 73.14 to 78% of PP resin and 20.14 to 25% of PA6 resin. The PP-PA6 polymer alloy resin has the advantages that the produced PP-PP6 polymer fiber is mainly used for earthwork engineering, net cage culturing, building safety nets, industrial filtering cloths, and the like; and meanwhile, along with the raising of the ratio of the PA6, the low-temperature shock-resistant performance, the anti-static performance, the pigmentation degree, the heat aging-resistant performance and the light aging-resistant performance are also improved, and the mechanical strength is improved.

Description

technical field [0001] The invention relates to a polymer material modification and polymer synthesis, in particular to a PP / PA-6 polymer alloy resin for spinning. Background technique [0002] Polypropylene (PP fiber) is a general-purpose fiber with an annual output of one million tons. Since PP resin has no polar groups and no chemically active groups, it is difficult to dye; light resistance, heat resistance, and high static electricity restrict the production of PP fibers. application and development. By blending and modifying high polymer with unobtained PP resin, the above-mentioned defects can be made up. However, when the content of the modified high polymer reaches 10%, it will be basically saturated. If the content continues to increase, it will appear rainy during spinning, making it difficult to form. Contents of the invention [0003] Based on the above deficiencies, the present invention mainly develops PP / PA-6 polymer alloys for spinning with polymer compa...
