Abstract

The invention discloses a high-polarity polypropylene material and the application thereof as inner and outer decorative parts of an automobile. The material is prepared from the following components in percentage by weight: 50-89 polypropylene, 5-25 flexibilizer, 0-30 mineral filler, 5-15 polar additives, 0.2-3 age resister and 0-0.5 colorant, and the components are premixed and then are extruded out by a double-screw extruder to prepare particles, thereby preparing the high-polarity modified polypropylene material. The surface tension of the material is as high as 37 dyne / cm<2>, dope-binding strength is high, an automobile bumper formed by the material can be coated without being pretreated, and when being used for preparing the inner decorative part for the automobile, the material has good property of binding other materials.

Description

technical field

[0001] The invention belongs to the technical field of modified materials, and in particular relates to a polypropylene (PP) composite material with enhanced polarity and its application. Background technique

[0002] Plastic plays an irreplaceable role for other materials in terms of car aesthetics, comfort, safety, anti-corrosion, light weight and large design freedom. Among the many polymer materials used in automobiles, the development and application of modified PP materials in automobiles has always been the focus of the automobile industry and the plastics industry. Modified PP materials that meet the different functional requirements of various automotive parts can be obtained through various modification processing methods. In addition to its excellent cost performance, various toughened, filled and reinforced PP materials have been obtained in the major assembly systems of automobiles. widely used. At present, the amount of PP materials used in a ...
