Abstract

The invention relates to engineering plastic and in particular relates to a reinforced and modified PA (Polyamide)6 composite material. The reinforced and modified PA6 composite material comprises the following components in parts by weight: 55-75 parts of PA6, 8-14 parts of glass fiber, 3-7 parts of MgO, 2-5 parts of dispersing agent, 1-2 parts of cross-linking agent and 0.1-0.5 part of antioxidant. The glass fiber adopted by the reinforced and modified PA6 composite material can be used for reinforcing the effect of the PA6, the MgO can be used for improving thermal deformation resistance capability of the PA6 to keep good dimension stability; and meanwhile, due to the lubricating and reinforcing effects of the nanometer particles. the wear resistance of the PA6 can be remarkably improved. The reinforced and modified PA6 composite material can be used for solving the problem that the PA6 in the prior art has defects in mechanical strength and wear resistance.

Description

technical field [0001] The invention relates to engineering plastics, in particular to a reinforced modified PA6 composite material. Background technique [0002] Polyamide (PA, commonly known as nylon) is a general-purpose engineering plastic with a long history and a wide range of uses. It has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, and the coefficient of friction Low, has a certain flame retardancy, and is easy to process. There are many varieties of PA, including PA6, PA66, PA46, PA610, PA612, PAl2, etc., as well as many new varieties such as semi-aromatic nylon and special nylon developed in recent years. Due to the different chemical structures of various nylons, their properties are also different. For PA6, it has a strong price advantage compared with PA46, PAl2 and other varieties, but it cannot meet the development requirements of related industries in terms of mech...
