| titleOfInvention | Glass fiber-reinforced polypropylene material with shallow shrinkage mark and low warpage as well as preparation method and application thereof |
| abstract | The invention discloses a glass fiber-reinforced polypropylene material with shallow shrinkage mark and low warpage as well as a preparation method and an application of the glass fiber-reinforced polypropylene material. The polypropylene material is prepared by using the following raw materials including 45-79% of polypropylene, 15-30% of chopped glass fiber, 1-20% of mineral fillers and 2-5% of grafted polypropylene, wherein the polypropylene includes high crystalline polypropylene as well as homopolymerized polypropylene and/or copolymerized polypropylene; the mineral fillers are one or more of barium sulfate, calcium carbonate or mica.The preparation method for preparing the glass fiber-reinforced polypropylene material provided by the invention uses the high crystalline polypropylene, the added chopped glass fiber and the mineral fillers for composite reinforcement and can effectively increase the cooling and curing rates of the material during the injection moulding process. The prepared product has the characteristics of shallow shrinkage mark, low warpage and high surface gloss, has the advantages of high flexural strength and modulus, good processability and low cost, can be used in household appliances and automotive industries, and can replace engineering plastic, and meet the requirements of high dimensional stability, high wrap and high mechanical properties of the parts. |
