Problems solved by technology

[0002] The traditional reinforced PA6 is generally dispersed in the PA6 material by shearing long glass fibers. The reinforced PA6 glass fiber distribution produced by this method has no orientation, and in some places it will cause poor appearance and lack of performance; and this enhanced PA6 shows obvious brittleness in low temperature environment (-20 degrees), and the data decline is extremely obvious, which cannot meet the use conditions in low temperature environment

Abstract

The invention discloses a formula and preparation method of PA6. the formula of PA6 comprises 50-60 parts of PA6, 30 parts of short glass fiber 301CL, 0.2-1 part of antioxidant, 0.1-0.5 part of coupling agent, 0.5-1 part of lubricating agent, 8-20 parts of EPDM (Ethylene-Propylene-Diene Monomer) graft and 1-3 parts of other processing agents. The invention also discloses a preparation method of PA6. The preparation method of f PA6 comprises the following steps of: selecting PA6 material and baking; stirring the PAB raw material; then adding silicone oil and stirring for a period of time; then adding the antioxidant, the lubricating agent and the other processing agents and stirring for a period of time; adding the EPDM graft and stirring for a period of time and adding the short glass fiber 301CL to finally obtain the semiproduct of PA6; and extruding the prepared semiproduct, cooling and cutting into grains to finally obtain the finished product of PA6. The reinforced PA6 material prepared by the method provided by the invention has the advantages of good appearance, good performance and high yield; in addition, the reinforced PA6 material has good toughness at an extremely low temperature and can be used in a low-temperature environment.

Description

technical field [0001] The invention relates to a formulation of PA6 and a preparation method thereof. Background technique [0002] The traditional reinforced PA6 is generally dispersed in the PA6 material by shearing long glass fibers. The reinforced PA6 glass fiber distribution produced by this method has no orientation, and in some places it will cause poor appearance and lack of performance; and this enhanced PA6 shows obvious brittleness in low temperature environment (-20 degrees), and the data declines extremely obviously, which cannot meet the use conditions in low temperature environment. Contents of the invention [0003] The invention provides a formula of reinforced PA6 resistant to extremely low temperature and its production method. The prepared reinforced PA6 material not only has good appearance, good performance and high yield, but also can ensure good toughness under extremely low temperature and meet low temperature requirements. Use the environment. ...
