Abstract
The invention discloses a low-smell toughening polyamide (PA)6 material. The low-smell tougheningPA6 material comprises the following raw materials in part by weight: 60 to 95 parts of nylon 6 resin, 5 to 40 parts of polyolefin, 0.5 to 5 parts of maleic anhydride, 0.1 to 0.5 part of peroxide and 0.2 to 5 parts of other additive. By the preparation method, the processing step of preparing toughening polyamide (PA)6 material is simplified, namely the primary two steps are combined into one step, and the preparation of the toughening polyamide (PA)6 material is realized by controlling a processing temperature. The production cost is reduced by the method; the prepared toughening polyamide (PA)6 material is excellent in performance and low in smell, has a certain practicability and commercial value and can be applied in fields, such as vehicles, electronics/electrical appliances and the like.
Description
technical field [0001] The invention relates to a low-odor toughened PA6 material and a preparation method thereof, which can be applied to the fields of automobiles and electronics / electric appliances, and belongs to the technical field of polymer materials. Background technique [0002] Nylon 6 (PA6) engineering plastic has good comprehensive properties such as wear resistance, self-lubrication, self-extinguishing, oil resistance and corrosion resistance. Weapons and construction and other fields. However, nylon also has its own disadvantages, such as high water absorption, poor dimensional stability, and low impact performance. For this reason, people usually adopt the method of adding grafted elastomers (such as grafted ethylene-1-octene copolymer or grafted EPDM rubber, etc.) to nylon to achieve toughening of nylon materials. [0003] For example, the patent CN1161353A, the title of the invention patent application is "an impact modifier and its preparation method and...
