Abstract

The invention provides a low-volatility modified polypropylene composite material, a preparation method and an application thereof. The low-volatility modified polypropylene composite material comprises the following components in parts by weight: 35-60 parts of low-flowability polypropylene, 40-60 parts of medium-flowability polypropylene, 0.4-0.8 parts of carbon black, 0-2 parts of an antioxidant, and 0-1 part of a lubricant. The invention provides a low-odor low-volatility environment-friendly product suitable for extrusion rolling production and applied to core layers of a luggage case anda carpet.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a low-volatility modified polypropylene composite material, a preparation method and an application thereof. Background technique [0002] At present, the three-layer composite carpet made of polypropylene material through extrusion calender is mostly used for interior carpet decoration of passenger cars, especially the trunk carpet and the left and right sides of the trunk. This kind of carpet is divided into three layers, the upper and lower layers are polypropylene non-woven felt, and the middle layer is a core layer of polypropylene material, which is mostly modified polypropylene material. Most of these core materials are made of single-extruded low-flow polypropylene materials, and some are made of low-flow modified polypropylene materials made of PP and mineral powder. The melt flow rate of the low-flow high-impact polypropylene material used by many extrusion...
