Problems solved by technology

However, due to the addition of glass fiber and compatibilizer, the polypropylene material has a certain degree of water absorption, especially after being used in washing machines and small household appliances for a long time, the polypropylene material is easy to absorb water and stain, and it is easier to breed bacteria Mildew, etc., greatly limit the selection and application of polypropylene materials
[0003] So far, it has not been found to fundamentally change the polarity of the surface of glass fiber reinforced polypropylene materials by analyzing the defects of glass fiber reinforced polypropylene materials for water absorption and staining, thereby improving the hydrophobic properties and antibacterial and antibacterial properties of glass fiber reinforced polypropylene materials. Relevant literature reports of mildew, thus limiting the application field and application level of glass fiber reinforced polypropylene materials

[0050] Examples 1-13 and Comparative Examples 1-5: Preparation of Glass Fiber Reinforced Polypropylene Composition

[0051] According to the ratio in Table 1, polypropylene, compatibilizer, highly hydrophobic additives, antibacterial agents and / or heat stabilizers and / or other additives are passed through a twin-screw extruder with an aspect ratio of 36-40:1 Melt, mix and disperse at 200°C-230°C, add glass fiber from the side feeding port, extrude and granulate to obtain a glass fiber reinforced polypropylene composition; the resulting glass fiber reinforced polypropylene composition is tested for its hydrophobicity after sample preparation The specific test data are shown in Table 1.

Abstract

The invention discloses a glass fiber reinforced polypropylene composition and a preparation method thereof. The glass fiber reinforced polypropylene composition comprises the following components in parts by weight: 41-92 parts of polypropylene, 5-40 parts of glass fiber, 1-10 parts of a compatibilizer, 0.1-10 parts of a high hydrophobic additive and 0.05-1 part of an antibacterial agent. A specific content of the high hydrophobic additive and the antibacterial agent are selected to be added into the glass fiber reinforced polypropylene composition formula, the polarity of the surface of the glass fiber reinforced polypropylene composition can be changed fundamentally, the hydrophobic performance of the glass fiber reinforced polypropylene composition is greatly improved, the antibacterial performance and the mildewproof performance of the glass fiber reinforced polypropylene composition are improved, the glass fiber reinforced polypropylene composition has very high self-cleaning property, the application field of a glass fiber reinforced polypropylene material is greatly widened, and the application level of the glass fiber reinforced polypropylene material is improved.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a glass fiber reinforced polypropylene composition and a preparation method thereof. Background technique [0002] Polypropylene, as a general-purpose plastic, has entered every corner of daily life. The polypropylene material modified by glass fiber has replaced engineering plastics in some applications due to its good rigidity. However, due to the addition of glass fiber and compatibilizer, the polypropylene material has a certain degree of water absorption, especially after being used in washing machines and small household appliances for a long time, the polypropylene material is easy to absorb water and stain, and it is easier to breed bacteria Mildew, etc., greatly limit the selection and application of polypropylene materials. [0003] So far, it has not been found to fundamentally change the polarity of the surface of glass fiber reinforced polypropylene mate...
