Soft PP flame retardant with ultrahigh fluidity

The invention discloses a soft PP flame retardant with ultrahigh fluidity. The soft PP flame retardant is prepared from 40-90% by mass of a base resin, 2-40% of a flame retardant, 1-30% of polar cooling master batches, 0.05-1% by mass of an antioxidant, 0.2-5% by mass of a dispersant, 0.1-1% by mass of a UV absorbent and 0.1-1% by mass of a light stabilizer. The soft PP flame retardant has low hardness, a good hand feeling, a low processing temperature, a narrow molecular weight distribution range, spinning easiness, good toughness, no precipitation, aging resistance, excellent mechanical properties, good adhesion to polyester, polyethylene and polypropylene, short consumption time, high production efficiency, production convenience, industrial production feasibility and good application prospect in a PP flame-retardant non-woven fabric. 本发明公开了种柔软且具有超高流动性PP阻燃料，按质量百分比计，由以下组分混合制成：基体树脂A 40-90％，阻燃剂2-40％，极性降温母粒1-30％，抗氧剂0.05-1％，分散剂0.2-5％，紫外吸收剂0.1-1％，光稳定剂0.1-1％。本发明硬度低、手感好、加工温度低、分子量分布窄易纺丝、韧性佳、无析出、耐老化、力学性能优良，与聚酯、聚乙烯、聚
