Abstract

The invention discloses an antimony oxide master batch special for flame-retardant non-woven fabric, which comprises the following raw materials by weight: 75%-93% of antimony oxide, 4%-15% of polypropylene resin, 1%-1.5% of a hyperdispersant, 0.4%-0.7% of trimethyl octadecyl ammonium bromide, 0.5%-3% of stearate, 0.3%-5% of a novel toughening auxiliary agent, and 0.1%-2% of zinc glutarate. The antimony oxide master batch is prepared through the steps of raw material weighing, premixing, re-stirring, melting, plasticizing, granulating, drying and the like. By implementing the innovative formula and the processing technology, the molding problem of the high melt mass flow rate type polypropylene resin applied to preparation of the antimony oxide master batch taking the polypropylene resin as the carrier can be effectively solved, and the production quality problems of mold sticking, particle breaking, particle connection and the like in particle cutting are solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of flame retardant preparation, and in particular relates to antimony oxide masterbatch special for flame retardant non-woven fabrics and a preparation method thereof. 【Background technique】 [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. New fiber products with soft, breathable and planar structure. The non-woven fabric made of polypropylene resin as the main raw material has a specific gravity of only 0.9, which is only three-fifths of the finished cotton non-woven fabric. It is bulky, feels good, and has excellent comprehensive properties. Wide range of applications. [0003] The main raw material of non-woven fabrics is high polymer, and high polym...
