Abstract

The invention specifically relates to a nanoparticle-modified nylon material and a preparation method thereof, belonging to the technical field of high polymer materials. The nylon material is prepared from the following raw materials: 100 parts by weight of a nylon matrix, 2 to 6 parts by weight of nanometer silicon carbide, 4 to 10 parts by weight of nanometer silica, 0.3 to 1 part by weight of 3-aminopropyltriethoxysilane, 5 to 15 parts by weight of a phenolic resin, 3 to 10 parts by weight of a glass fiber and 1 to 10 parts by volume of a volatile solvent which is in the liquid state at normal temperature. The nanometer modified nylon material provided by the invention has obviously better tensile strength, compression strength, notch impact strength, thermal deformation temperature, friction coefficient, heat conductivity and water absorption compared with conventional products and has excellent application performance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a nylon material and a preparation method thereof. Background technique [0002] Traditional wear-resistant plates are generally metal materials. Metal products wear out quickly during use, have a short service life, and require heavy maintenance work. Metal materials are not easy to insert and rotate, and difficult to operate. Modified plastics are the focus of the development of high-tech materials in my country. Modified plastic products can not only achieve the strength properties of some steel materials, but also have the advantages of light weight, easy processing and molding, high toughness, high impact resistance, and wear resistance. Therefore, the current trend of "replacing steel with plastic" is emerging in many industries. [0003] Nylon (PA), also known as polyamide, has excellent physical and mechanical properties, and has the advantages of high stren...
