Description
Technical Field
The invention belongs to the technical field of high polymer materials, and particularly relates to a vacuum glass bead/glass fiber mixed reinforced polypropylene material and a preparation method thereof.
Background
The polypropylene material has the advantages of light weight, good chemical resistance, high-frequency insulating property, small specific gravity, easy processing and forming, low price and the like, and is widely applied to the fields of automobile industry, electronic and electric industry, household appliances, textile and the like. Compared with the traditional automobile, the electric motor is a great trend of development of the automobile industry. For new energy automobiles, the weight of the power battery can reach hundreds of kilograms. Only by light weight, the weight of the expensive battery can be reduced, the cost of the vehicle can be reduced, and the market demand can be met. Related researches show that the endurance mileage can be increased by 10% -11% when the new energy automobile is reduced by 100 kg. It can also reduce battery cost by 20% and daily wear cost by 20%. Therefore, new energy automobiles are being developed toward weight reduction of the entire vehicle.
At present, glass fibers are generally used for filling reinforced polypropylene materials, so that the polypropylene materials are easy to generate a phenomenon of floating fibers, the appearance is influenced, and the mechanical properties are also reduced; in addition, the density of the glass fiber is high, so that the specific gravity of the filled and reinforced polypropylene material is high, and the development requirement of automobile weight reduction is not met.
Therefore, how to provide a vacuum glass bead/glass fiber mixed reinforced polypropylene material and a preparation method thereof so as to reduce the specific gravity of the polypropylene material is a technical problem which needs to be solved by the person skilled in the art.

In example 2, on the basis of the examples, a small amount of toughening agent is added, and the toughening effect is achieved after the content of the compatilizer exceeds a certain amount, so that the toughening efficiency is improved by using a toughening agent/compatilizer composite toughening method, the flexural modulus is partially lost because the rigidity of the material is reduced by adding the toughening agent, the other mechanical properties are obviously improved, the density is further reduced, the damage of external force to the vacuum glass beads in the extrusion and injection molding processes is reduced after adding a small amount of toughening agent, and the buffering effect is achieved, so that the tensile strength and the flexural strength of the material are improved.
