The invention discloses a high-strength, high-modulus and low-shrinkage electroplating nylon material and a preparation method thereof. A material composition formula comprises the following components in percentage by weight: 23-75 percent of nylon resin, 5-10 percent of PA1335 5, 0-35 percent of glass fibers, 20-30 percent of filled minerals, 0-1 percent of a lubricating agent and 0-1 percent ofan antioxidant. The high-strength, high-modulus and low-shrinkage electroplating nylon material and the preparation method thereof have the benefits that 1, the invention provides electroplated nylon, the nylon material is endowed with the electroplating properties by adopting the filled mineral with a special size and weak alkalinity, and is outstanding in mechanical properties and excellent inelectroplating effect; 2, an electroplating system prepared according to the method is high in mechanical strength and overcomes the defect that a traditional glass fiber reinforcement system cannot be electroplated; in combination with the structure design, metals in parts such as door handles and mobile phone frames can be replaced, so that the purpose of reducing the weight is achieved.
