Abstract

The invention discloses a reinforced and toughened polypropylene plastic and a preparation method thereof. The reinforced and toughened polypropylene plastic comprise the following components in parts by weight: 70-90 parts of PP (Propene) resin, 5-15 parts of POE (Polyolefin Elastomer) resin and 5-15 parts of barium sulfate. Compared with the pure PP plastics, the reinforced and toughened polypropylene plastic is improved in tensile yield strength and has higher rigid strength; besides, the reinforced and toughened polypropylene plastic is greatly improved and has better toughness. The reinforced and toughened polypropylene plastic can be widely applied to the production of products such as household appliances, plastic pipes and automotive interior parts.

Description

technical field [0001] The invention relates to a plastic and a preparation method thereof, in particular to a reinforced and toughened polypropylene plastic and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials. [0003] The ability of a material to absorb energy and undergo plastic deformation before fracture. Contrary to brittleness, the material has a large deformation before fracture, and the fracture often presents an epitaxial deformation. This deformation cannot be recovered immediately, and its stress-strain relationship is nonlinear and consumes a large amount of fracture energy. Usually measured by the size of the impact strength. The better the toughness, the less likely brittle fracture wi...
