Abstract

The invention discloses super-nylon 66 alloy prepared by an in-situ reactive compatibilization method and a preparation method thereof, and the preparation method is used for improving the compatibility of nylon 66 and POE (poly ortho ester), and preparing the super-nylon 66 alloy with high toughness, low temperature resistance and low water absorption rate. The super-nylon 66 alloy comprises the following compounds in parts by weight: 55 to 95 parts of nylon 66, 5 to 45 parts of POE, 0.01 to 1 part of initiating agent, and 0.1 to 4 parts of maleic anhydride, wherein the initiating agent is organic peroxide. The super-nylon 66 alloy provided by the invention has excellent comprehensive performance, in particular high notch impact strength, excellent low temperature impact resistance and low water absorption rate; and the product can be used in producing various automobile parts, mechanical parts, electronic appliances, package materials and the like with high toughness, abrasion resistance and excellent self-lubrication performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a method for preparing a nylon 66 alloy with high toughness, low temperature resistance and low water absorption by using an in-situ reaction compatibilization method. Background technique [0002] Polyamide, also known as nylon (PA), is the basic resin with the widest application, the largest variety, the largest output, and excellent comprehensive performance among the five general-purpose engineering plastics. PA66 is a translucent or opaque milky white crystalline polymer. It has the advantages of high strength, wear resistance, solvent resistance and wide temperature range. It is widely used in automobile manufacturing, mechanical equipment, electronic appliances, medical equipment and precision instruments. However, due to the characteristics of strong polarity, PA66 has the disadvantages of strong hygroscopicity, poor dimensional stability, and low notched impact stren...
