Problems solved by technology

Although there are many types of PP modified materials of various grades on the market, the composite materials are not easy to process or the appearance of the products is poor due to fillings such as minerals and glass fibers, and many modified PP materials have complex formulas, making it difficult to take care of various types. Balance of performance; PP modified materials that can balance ordinary mechanical properties and have good aging resistance are relatively few, or a good balance of properties has been obtained, but the cost is high

Description

technical field [0001] The invention relates to the field of polypropylene modified materials, more particularly, to a mineral modified polypropylene composite material for vehicles and a preparation method thereof. Background technique [0002] With the development of the automobile industry, more and more automobile parts choose modified engineering plastics to replace metal parts, and more and more plastic varieties can be applied, such as PP (polypropylene), PA (nylon), ABS ( polyacrylonitrile-butadiene-styrene), PBT (polybutylene terephthalate), PET (polyethylene terephthalate), and the like. The application of plastics in automobiles has been developing for more than half a century, which has greatly promoted the lightweight development of automobiles, promoted energy conservation and emission reduction, and provided drivers with a good driving experience and riding comfort. [0003] In the development and application of many automotive plastics, PP materials have bee...
