Problems solved by technology

Traditional anti-scratch agents are mainly erucamide substances and high polysiloxane substances. These two types of substances have their own disadvantages such as heavy odor. When polypropylene composite materials are used in automotive interior parts, there will be impact Indoor environment VOC, odor and other issues

Abstract

The invention relates to a reinforced and scratch-resistant polypropylene material and a preparation method thereof, wherein the material is prepared from 70-95 parts of polypropylene, 30-5 parts of SiAlON, 0.1-0.5 part of a coupling agent, 0.1-1 part of a thermal stabilizer, 0-1 part of a lubricant, and 0-0.5 part of white oil, and the weight sum of the polypropylene and the SiAlON is 100 parts. According to the present invention, the one-dimensional beta-SiAlON adopted as the scratch-resistant agent is added to the polypropylene material so as to concurrently provide advantages of material scratch resistance enhancing and material strength increasing and overcome the disadvantage of the material scratch resistance reducing of the traditional reinforcing filling material; and the obtained reinforced and scratch-resistant polypropylene material is used in vehicle interior decoration materials, and does not have disadvantages of scratch-resistant agent precipitation, odor, appearance and the like compared to the traditional scratch-resistant agent adding material.

Description

technical field [0001] The invention relates to the technical field of polypropylene, in particular to a reinforced and scratch-resistant polypropylene material and a preparation method thereof. technical background [0002] Polypropylene material is widely used in interior and exterior parts of automobiles due to its advantages of low price and light weight. However, the scratch resistance of the polypropylene material itself is poor, especially the scratch resistance of the polypropylene material filled with talcum powder is even worse, and the material yields under the action of pressing force and sliding force or transverse (lateral) force, Ductile / brittle failure occurs resulting in scratches. In scratches, the uneven surface produces uneven light scattering and "scratch whitening", which limits the use of polypropylene materials in parts where scratch resistance is required. [0003] In order to solve this problem, a scratch-resistant agent is usually added to the po...
