Problems solved by technology

The weakly polar part of the compatibilizer molecule is mainly combined with the polypropylene matrix through van der Waals force and other non-covalent bonds, and its binding force is relatively weak, which has a limited effect on improving the mechanical properties and heat resistance of the alloy.

Abstract

The invention discloses a polypropylene / polyamide alloy as well as a preparation method and an application thereof, and relates to the technical field of high polymer materials. The polypropylene / polyamide alloy is prepared from the following components in parts by weight: 41.3 to 74.3 parts of polypropylene, 15 to 55 parts of polyamide and 3 to 10 parts of a compatilizer, the structural formula of the compatilizer is shown in the specification, n is an integer between 0 and 8, and R is alkyl or alkoxy. The material with the structure is selected as the compatilizer, so that the mechanical property and the heat resistance of the polypropylene / polyamide alloy are greatly improved, and the polypropylene / polyamide alloy is applicable to the fields of automobiles, household appliances, electric tools and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polypropylene / polyamide alloy and its preparation method and application. Background technique [0002] Polypropylene has the advantages of low density, low price, low water absorption and easy processing. It is widely used in industries such as automobiles, home appliances and electric tools. However, compared with polyamide and other engineering plastics, polypropylene also has the disadvantages of low mechanical properties and insufficient heat resistance, so it is difficult to apply to some fields that require high mechanical properties and heat resistance, such as the peripheral application of automobile engines. In order to overcome the inherent shortcomings of polypropylene, blending polypropylene and polyamide to prepare alloys is an ideal solution. However, polypropylene and polyamide belong to weak polar polymers and strong polar polymers respectively, and ...
