Description
Technical Field
The invention relates to a functional polypropylene material and a preparation method thereof, in particular to a scratch-resistant and sticky-resistant polypropylene composite material and a preparation method thereof, belonging to the technical field of polypropylene.
Background
The polypropylene is a plastic variety with the largest usage amount and the fastest development speed in the plastic for vehicles due to the characteristics of small density, high cost performance, excellent heat resistance, easy molding and processing and the like. However, the conventional polypropylene has a limitation in the application in the automobile industry due to its high shrinkage rate and low modulus, and can meet basic performance requirements after being subjected to filling and toughening modification, but this also causes the scratch resistance to be reduced, and limits the application in the automobile interior materials. Theoretically, the scratch resistance of the surface of the polypropylene material can be improved by two ways, wherein one way is to reduce the friction coefficient of the surface of the polypropylene material by adding a lubricant (a scratch resistance auxiliary agent) and the like; secondly, the surface hardness of the polypropylene material is increased by adding a nucleating agent or selecting polypropylene with higher isotacticity, but the method also causes the loss of the toughness of the material while improving the hardness of the material, and is rarely adopted. At present, scratch resistance of polypropylene composite materials is improved mainly by blending and adding scratch-resistant auxiliary agents in the market, the used scratch-resistant auxiliary agents are mostly small-molecular lubricants such as amides, silicones and the like, and the method mainly has the following defects: (1) the selected lubricant has small molecular weight, and is easy to separate out in the long-term use process of the material to cause the surface of a product to be sticky; (2) the selected lubricant has poor compatibility with the polypropylene material, and is easy to separate out in the use process of the material, so that the stress whitening phenomenon is generated to influence the use performance of the material. For example, patent CN101787159A discloses a scratch-resistant material special for automotive upholstery and a preparation method thereof, which adopts an amide lubricant added with small molecules to reduce the surface friction coefficient of the material, thereby improving the scratch resistance of the polypropylene material.
Therefore, in order to endow the polypropylene composite material for the vehicle with good scratch resistance, the selection of the scratch assistant and the improvement of the surface hardness of the material as much as possible (on the premise of not damaging the toughness of the material) are both important. The ultra-high molecular weight polyethylene as a high molecular compound has super wear resistance, surface self-lubricating property and good compatibility with a polypropylene material, has good improvement effect on the mechanical properties such as scratch resistance, impact toughness and the like of the polypropylene material when added into the polypropylene composite material, does not generate phenomena such as separation and stickiness and the like the traditional scratch assistant, and has incomparable advantages in performance compared with the traditional scratch assistant. In addition, the novel functional talcum powder with the needle-like structure is newly developed by experts of inorganic minerals such as talcum powder and the like aiming at improving the scraping performance of the polypropylene composite material for vehicles in recent years. The functional talcum powder has a special needle-shaped structure, so that the surface hardness of the polypropylene composite material can be effectively improved, the scratch resistance of the polypropylene composite material is well promoted, and the amount of a scratch-resistant auxiliary agent can be partially replaced or reduced.
