Abstract
The invention discloses a scratch-resistant easy-to-wipe flame-retardant polypropylene composition for a converter. The polypropylene composition comprises the following components in parts by weight:80-100 parts of co-polypropylene, 40 to 60 parts of homo-polypropylene, 10 to 15 parts of 2,4,6-tribromophenyl methyl heptenoic acid ester, 3 to 5 parts of Sb2O3, 2 to 3 parts of boron-doped heteroatom polysiloxane, and 2 to 5 parts of oligomerization degree polysiloxane. According to the invention, through selection of specific raw materials, the problem that flame retardance is influenced by high degradation rate of polysiloxane in an acid environment of a flame retardant is solved, and the problem that polypropylene material is easy to wipe and resistant to scraping of soft cleaning articles is solved.
Description
technical field [0001] The invention relates to a scratch-resistant and easy-to-wipe flame-retardant polypropylene composition for a converter, which belongs to the field of composite materials. Background technique [0002] Power converters are widely used electrical accessories in daily life, with a large production volume and diverse application scenarios, reaching 200-300 million units per year. With the improvement of people's living standards, the application requirements in special scenarios are gradually subdivided, such as kitchens and other scenes with a lot of oil stains or other dusty scenes, users not only require basic requirements such as flame retardancy, heat resistance, and ease of use. , Ease of cleaning with a cleaning cloth has gradually become one of the key indicators. While it is easy to clean with soft cleaning products, it also needs to not affect the aesthetics of its surface, which requires the material to have a certain degree of scratch resista...
