Abstract
The invention aims to provide a polyamide PA6 reinforced modified material without affecting material mechanical properties and with improved polyamide material mechanical properties and a preparationmethod thereof. The chemical and physical properties of polyamide PA6 are similar to those of nylon 66; however, the polyamide PA6 is lower in melting point and wide in process temperature range. Theimpact resistance and the solubility resistance of the polyamide PA6 are better than those of PA66, and the hygroscopicity is also stronger. As the multiple quality characteristics of a plastic partare affected by the hygroscopicity, when the polyamide PA6 is used for designing a product, the hygroscopicity needs to be fully considered. The polyamide PA6 reinforced modified material provided bythe invention has the benefit that the mechanical properties of the material are greatly improved, so that the material can be better applied.
Description
technical field [0001] The invention belongs to the technical field of nylon PA6 material production, which improves the mechanical properties of the polyamide material and produces products meeting social needs. Background technique [0002] The chemical and physical properties of polyamide PA6 are very similar to nylon 66, however, it has a lower melting point and a wide range of process temperatures. Its impact resistance and solvent resistance are better than PA66, but it is also more hygroscopic. Because many quality characteristics of plastic parts are affected by hygroscopicity, this should be fully taken into account when designing products using polyamide PA6. Contents of the invention [0003] The object of the present invention is to provide a polyamide PA6 reinforced modified material which does not affect the mechanical properties of the material and improves the mechanical properties of the polyamide material and a preparation method thereof. [0004] The p...
