[0003] Regarding spray-free polymer materials, Chinese Patent Publication No. CN105504646A disclosed a spray-free scratch-resistant polypropylene composite material for automobile bumpers and its preparation method on April 2, 2016. The scratch-resistant agent used in it It is oleic acid amide, which is easy to produce sticky surface, which is not conducive to maintaining the scratch resistance effect for a long time, and the scratch resistance agent is a small molecular substance, which is easy to produce volatile gas and affect the odor performance of the material
In the case of more and more stringent automobile odor requirements, the odor requirements of materials are also getting higher and higher, and the materials prepared by this preparation method cannot meet the odor requirements
Chinese patent CN201210036011.6 disclosed on July 18, 2012 a non-spraying polypropylene composition with paint glossy metallic texture and its preparation method. The patent did not select the corresponding additives to solve the compatibility problem, which would easily lead to poly Acrylic composition has flow marks, tiger skin patterns, and poor scratch resistance
Patent CN201310670823.0 disclosed on April 2, 2014 a spray-free scratch-resistant polypropylene composite material for automotive interior parts and its preparation method. This patent does not involve the antistatic performance of the material, which is easy to absorb dust. Decorative materials are less comfortable due to electrostatic effects in dry air environments

Abstract

The invention discloses a spray-coating-free scraping-resistant polypropylene material for an automobile and a preparation method thereof. The polypropylene material is prepared from the following rawmaterials in parts by weight: 50 to 85 parts of high crystalline polypropylene, 10 to 22 parts of calcium carbonate, 5 to 10 parts of toughening agents of vinyl-octene copolymers, 1 to 4 parts of organosilicon scratch-resistant agents, 0.5 to 4 parts of aluminum pigments, 0.1 to 0.5 part of organic phosphate nucleating agents, 0.3 to 0.8 part of coupling agents of alkyl modified polysiloxane, 0.2to 0.8 part of hindered amine light stabilizers, 0.2 to 0.8 part of antioxidants and 0.3 to 0.8 part of antistatic agents. The spray-coating-free scraping-resistant polypropylene material has the advantages that the long-time scraping-resistant effect is good; the metal luster effect is relatively good; the dimension stability is higher; the production process is simple; the production cost is low; the environment is protected.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a spray-free scratch-resistant polypropylene material for automobiles, and also relates to a preparation method of the spray-free scratch-resistant polypropylene material for automobiles. Background technique [0002] With the continuous development of the automobile industry, new materials and new technologies are constantly being applied and promoted, and modified polypropylene materials for automobiles are also constantly being improved and innovated. Polypropylene material is generally not resistant to scratches, and its surface hardness is low. It is easy to be bumped and scratched during use, which affects its appearance quality. At present, some parts of the interior and exterior of automobiles are usually sprayed with paint to achieve a beautiful appearance, but the paint spraying process is cumbersome, which will have a great impact on the environment and individuals, ...
