Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of nano-type reinforced MC nylon composition and its preparation method in view of the characteristics of the widely used nylon plastics, which not only solves the problem of glass fiber exposure in the injection molding process of engineering plastics, but also improves the quality of the product. The appearance quality has improved the physical properties of the product, especially the bending strength has more than doubled that of ordinary reinforced plastics, which has improved the product to a new level and changed the pattern of some domestic manufacturers relying on imports

Embodiment 1

[0023] A nano-type reinforced MC nylon composition, which is obtained by blending the following main raw materials and extruding them at 215-250°C:

[0024]

[0025] The method for preparing the nanotype reinforced MC nylon composition of the present invention, its main steps are:

[0026] The first step, add 70g168, 70g1076, 350gEBS into the mixer and mix for 10 minutes, the resulting mixture is ready for use;

[0027] The second step is to dry the MC nylon slices at a temperature of 90°C for 6 hours;

[0028] The third step is to add 25Kg dried MC nylon chips, 10K glass fiber, the mixture obtained in the first step, 750g powdered polytetrafluoride and 65gKH560 into the extruder, and melt and extrude at 250°C to obtain the extrudate ;

[0029] The fourth step, the extrudate is cooled by water cooling;

[0030] The fifth step is dicing, grading, and packaging the finished product after cooling.

Abstract

A nano-type reinforced MC nylon composition, which is obtained by blending the following raw materials in percentage and extruding them at 215-250°C:.

Description

technical field [0001] The invention relates to the field of engineering plastics, in particular to a nanometer reinforced MC nylon composition. Background technique [0002] The peripheral parts of automobile engines are mainly heat-generating and vibrating parts, so the materials used must have high comprehensive performance. However, due to the poor dispersion and fluidity of glass fibers, there are obvious weld marks and flow marks on the surface of injection molded products, and there are even glass fibers. The phenomenon of fiber exposure seriously affects the appearance of the product. Nylon has the advantages of high strength, wear resistance, solvent resistance, good self-lubricating property and wide temperature range. It has outstanding chemical resistance and oil resistance. It is the most widely used variety among the five major engineering plastics. It is now widely used in various electronic and electrical equipment. and home appliances. Contents of the inv...
