Abstract

The invention relates to the technical field of polypropylene, in particular to a flame-retardant polypropylene with light specific gravity and impact resistance and a preparation method thereof. The flame-retardant polypropylene comprises 70-80 percent of polypropylene, 6-10 percent of flame retardant, 3-8 percent of antimony oxide, 5-8 percent of flexibilizer, 5-10 percent of antioxidant, 5-10 percent of antioxidant adjuvant and 5-10 percent of hexylene radical bis stearamide according to weight percentage. The flame-retardant polypropylene not only is light in specific gravity and resistant to impact, but also retards flame, greatly reduces the production cost of manufacturers while clearing away the potential fire hazard of plastic furniture, especially solves the technical difficulty of PP reactive flame retardant and flexibilizer with cooperativity and is at leading level at home and abroad. Proved by tests, the physical property can simultaneously meet the requirements of impact-resistant and fireproof UL94-V0 of plastic chairs.

Description

technical field [0001] The invention relates to the technical field of polypropylene, in particular to a flame-retardant polypropylene with light specific gravity and impact resistance and a preparation method thereof. Background technique [0002] Polypropylene, referred to as PP, is widely used in packaging, automobiles, home appliances and other fields because of its non-toxic, odorless and excellent physical and chemical properties. Especially in recent years, new modified additives and new mixing processes have improved the rigidity and toughness of polypropylene. With the changing requirements and improvements in various aspects such as room decoration, PP materials are increasingly used in many items in the market, especially in furniture, and PP material products are very popular. [0003] Due to the particularity of furniture, especially plastic chairs, people have relatively high requirements on the performance of its manufacturing materials; the production and te...
