Problems solved by technology

However, polyamide materials also have some defects: on the one hand, there are polar amide bonds in PA molecules, which are easy to absorb water, resulting in poor dimensional stability and reduced mechanical strength; on the other hand, the notched impact toughness of PA is poor, and under the condition of 1.80MPa The heat distortion temperature is low, these problems limit its application range
However, glass fibers tend to cause floating fibers on the surface of nylon materials, which increases the roughness, which is not conducive to the adhesion of the electroplating layer, and the electroplating effect becomes poor; the compatibility of inorganic minerals and polymer materials is poor, and the dispersion is not good, which limits its improvement. The electroplatability of nylon materials can play a role, and it may cause the impact resistance of nylon materials to decline

Abstract

The invention provides an electroplated nylon material and a preparation method thereof. The electroplated nylon material comprises the following components in parts by weight: 40-80 parts of polyamide, 10-50 parts of modified minerals and 10-30 parts of modified glass fibers, wherein the total parts by weight of polyamide, modified minerals and modified glass fibers are 100 parts; the modified mineral is a mineral of which the surface is bonded with a silane coupling agent and adsorbs rare earth ions; the modified glass fiber is glass fiber of which the surface is bridged with maleic anhydride grafted ultra-high molecular weight polyethylene through a silane coupling agent and which adsorbs rare earth ions. The electroplated nylon material is prepared by mixing the components and then carrying out melt extrusion by using an extruder. The electroplating nylon material provided by the invention has good electroplating performance, rigidity, heat resistance and impact toughness through synergistic cooperation of the modified minerals and the modified glass fibers.

Description

Technical field [0001] The invention belongs to the technical field of nylon materials, and relates to an electroplated nylon material and a preparation method thereof. Background technique [0002] Polyamide (PA) is commonly known as nylon. It is a linear polymer with a repeating unit amide bond (-CONH-) in the molecule. It can be formed by polycondensation of dibasic acid and diamine, or it can be polymerized by ring opening of amino acid caprolactam. Polyamide is an engineering plastic with excellent performance. It has good mechanical strength, self-lubricating performance, good wear resistance, shock absorption and noise reduction. It is widely used in machinery, automobiles, electrical appliances and other industries. However, polyamide materials also have some disadvantages: on the one hand, there are polar amide bonds in the PA molecules, which are easy to absorb water, resulting in poor dimensional stability and reduced mechanical strength; on the other hand, the notched...
