Abstract

The invention discloses a nylon composite material filled with nano silicon nitride, belonging to the technical field of high polymer materials. The nylon composite material comprises the raw materials in parts by weight: 180-210 parts of nylon 66 resin, 70-85 parts of nylon 6 resin, 1.5-2.4 parts of coupling reagent, 70-95 parts of fille, 20-26 parts of nano silicon nitride, 0.6-1.0 part of antioxygen, 103-126 parts of glass fibre and 0.3-0.7 part of oleamide. The nylon composite material has the advantages that the surface is improved by adopting the oleamide for preventing the glass fibre from escaping to the outside so as to greatly inhibit water absorbing quality; and according to the test results of mechanical and physical properties, tensile strength is more than 170MPa, bending strength is more than 250MPa, cantilever notch impact strength is more than 24.5kj / m<2>, and a melt index is more than 18g / 10min.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a nylon composite material filled with nanometer silicon nitride. Background technique [0002] Nanomaterials are new materials developed in recent years. Nanoparticles have special scale effects and have been continuously applied to the modification of polymeric materials in recent years. Nylon material is a kind of plastic with excellent comprehensive performance, but due to its strong water absorption, poor creep resistance and unsatisfactory mechanical and physical properties, nylon material limits its application in special fields (such as vehicles). Therefore, it is of positive significance to develop a nylon material that can remedy these defects. For this reason, the applicant has made a beneficial attempt, and the technical solution to be introduced below is based on this premise. Contents of the invention [0003] The task of the present inventi...
