Problems solved by technology

However, the odor of the modified polypropylene material is the result of the interaction of odors of various components; only by adding an adsorbent that absorbs a single odor to reduce the odor, the actual effect is limited, and the odor cannot be removed well; at the same time , the amount of fluoropolymer added is too much, which increases the production cost

Abstract

The invention relates to a low-odor scraping-resistant polypropylene material and a preparation method of the low-odor scraping-resistant polypropylene material and belongs to the technical field of polypropylene materials. In order to solve the technical problems that the odor of the polypropylene material in the prior art is difficult to eliminate, the odor can be eliminated only through aiming at a certain single ingredient, the scraping resistance is poor, and the production cost is high when fluorine-containing polymers are adopted for production. The invention provides the low-odor scraping-resistant polypropylene material and also provides the preparation method of the polypropylene material, wherein the polypropylene material comprises acrylic resin, nanometer silicon dioxide, ultra-fine talcum powder, odor eliminating agents, disperse lubricating agents, antioxidants and hindered amine light stabilizers, the method comprises material mixing and squeezing granulation steps, and the low-odor scraping-resistant polypropylene material is obtained. The polypropylene material provided by the invention has the advantages of low odor and scraping resistance. The product obtained from the material has the advantage that the performance such as tensile strength, bending strength, cantilever beam notch impact strength and delta L is high. The method has the advantages that the process is simple, the operation is easy, raw materials are easy to obtain, and the industrial production is favorably realized.
