Problems solved by technology

The method of simply using fillers to increase the gloss of the material can improve the gloss to a certain extent, but at the same time it will reduce the mechanical properties (such as toughness) and fluidity of the material, and cannot be used for products with thin walls and complex structures.

Abstract

The invention relates to a high-liquidity high-glossiness flame retardant toughened polypropylene material and a preparation method thereof. The material comprises the following components in parts by weight: 100 parts of polypropylene, 5-10 parts of a toughening agent, 1-5 parts of graft, 10-20 parts of high-glossiness barium sulfate, 10-14 parts of a flame retardant, 5-7 parts of an auxiliary flame retardant, 0.05-0.2 part of a nucleating agent, 0.2-0.4 part of an antioxidant, 0.2-0.4 part of a surface treating agent, 0.2-0.5 part of a dispersing lubricant and 0.03 part of a fluorescent whitening agent. The preparation method comprises the following steps: firstly, mixing the surface treating agent, the dispersing lubricant, the high-glossiness barium sulfate, the flame retardant and the auxiliary flame retardant; then, mixing the polypropylene, the toughening agent, the graft, the nucleating agent, the antioxidant and the fluorescent whitening agent with the mixture; and finally, extruding and pelletizing. The material prepared by the preparation method disclosed by the invention has high glossiness, high impact, high liquidity and flame resistance, and is suitable for requirements of household appliances; meanwhile, compared with the acrylonitrile-butadiene-styrene copolymer, the high-liquidity high-glossiness flame retardant toughened polypropylene material is low in price.

Description

technical field [0001] The invention relates to a polypropylene material and a preparation method, in particular to a high-flow, high-light, flame-retardant and toughened polypropylene material and a preparation method thereof. Background technique [0002] As one of the five general-purpose materials, polypropylene has excellent comprehensive performance, good chemical stability and relatively low price. Its use is constantly expanding, and it currently occupies a certain seat in the field of daily electrical appliances. High-gloss polypropylene, as the most ideal material to replace acrylonitrile-butadiene-styrene copolymer high-gloss products, has aroused people's interest and extensive research. At present, this type of modified polypropylene abroad is widely used in daily household appliances such as microwave ovens, electric water heaters, and rice cookers. Generally, modified polypropylene for household appliances has flame retardant requirements, and flame retar...
