Abstract

The invention relates to a low-odor low-VOC polypropylene composite material, a preparation device and a method thereof and belongs to the technical field of an organic polymer material. The material is prepared from polypropylene resin, filler, functional additive, processing heat stabilizer, processing lubricating agent and silicone oil at mass ratio of 55-97:(0-20):(0.5-20):(0.2-1):(0.1-2):(0.05-0.1). In the preparation process, water is taken as an extracting agent and is added through a water feeding port formed on an extruding machine, and meanwhile, the vacuum port position in the extruding machine is modified, so that the purpose of removing the harmful volatile organic compounds from the composite material in stages can be realized; vacuum extraction is adopted after the water extraction, so that the residue of the harmful volatile organic compounds in the composite material can be greatly reduced; the secondary pollution caused by the use of organic extraction agent can be avoided; the influence on the properties of the base material is reduced; and the low-cost, low-odor and low-VOC polypropylene composite material is finally prepared.

Description

technical field [0001] The invention belongs to the technical field of organic polymer materials, and in particular relates to a low-odor, low-VOC polypropylene composite material and a preparation device and method thereof. Background technique [0002] Due to the influence of polymerization process, catalysts, oxide residues and short-chain oligomers, polypropylene materials will release harmful volatile organic compounds (VOC) to varying degrees during high-temperature processing and use. At the same time, limited by its own performance, most of its strength, stability, processability, and functionality cannot meet the requirements of use, and cannot be directly used to produce plastic products. At present, it is generally used to improve its performance by adding functional additives, and commonly used functional additives, such as flame retardants, tougheners, coupling agents, lubricants, stabilizers and other materials, may bring some harmful VOC , and the smell is ab...
