Abstract

The invention belongs to the technical field of nylon materials, and particularly relates to a toughened nylon material and a preparation method thereof, and the toughened nylon material is prepared from the following components in parts by weight: 65-80 parts of PA66, 8-12 parts of a premixed toughening material, 5-8 parts of epoxy functionalized ethylene propylene rubber, 2-5 parts of maleic anhydride grafted polyethylene, 3-6 parts of talcum powder, 1-2 parts of a heat stabilizer, 0.5-1 part of a coupling agent and 0.5-1 part of an antioxidant. According to the invention, the premixed toughening material composed of the chopped carbon fiber, the caprolactam monomer, the SiC and the glass fiber is used for toughening the PA66, and the epoxy functionalized ethylene propylene rubber, the maleic anhydride grafted polyethylene and various additives are combined, so that the toughened PA66 has relatively high elongation at break and impact strength, the tensile strength, the bending strength and the tensile elastic modulus are relatively small, the toughness is high, meanwhile, the heat stability is high, the service life is long, the size stability is good, and compared with the prior art, the overall performance is obviously improved.

Description

technical field [0001] The invention relates to the technical field of nylon materials, in particular to a toughened nylon material and a preparation method thereof. Background technique [0002] Polyamide is usually called nylon, which is a high polymer containing repeating amide groups in the main chain of the polymer molecule, including ring-opening polymerization or polycondensation of monomers with amino and carboxyl groups, or diamines and dibasic acids are made by polycondensation reactions The resin has excellent thermal properties, mechanical properties, electrical insulation, corrosion resistance and other comprehensive properties, and is widely used in technical fields including automobiles, electronic devices, optical components, lenses, petrochemical windows, and nylon pipes. [0003] In order to improve the strength of the existing nylon materials in the preparation process, the elongation at break and the impact resistance of the nylon materials are reduced. ...
