Abstract

The invention discloses a medium-alkali glass fiber reinforced regenerated polypropylene composite material, which comprises the following components in parts by weight: 70-90 parts of polypropylene,10-30 parts of medium-alkali glass fibers and 0.5-3 parts of a stiffening nucleating agent. According to the invention, the regenerated polypropylene material is synergistically modified by the medium-alkali glass fiber with good toughness and low cost and the stiffening nucleating agent, and the prepared glass fiber reinforced regenerated polypropylene material has an excellent rigidity-toughnessbalanced performance, and can be used in reinforcing material parts needing nailing and bending. Meanwhile, the invention further discloses a preparation method and application of the medium-alkali glass fiber reinforced regenerated polypropylene composite material.

Description

technical field [0001] The invention relates to a polypropylene composite material and its preparation method and application, in particular to a medium-alkali glass fiber reinforced recycled polypropylene composite material and its preparation method and application. Background technique [0002] Polypropylene is widely used in home appliances, office furniture and auto parts due to its advantages of low density, high cost performance, non-toxic and tasteless, corrosion resistance and excellent comprehensive performance. However, polypropylene is relatively difficult to degrade, so with the development of industry, the amount of waste polypropylene is increasing year by year, and it is particularly important to recycle waste polypropylene. [0003] The performance of waste polypropylene materials has declined due to partial aging and degradation. Simple recycling and reuse cannot meet the needs of most products. Therefore, in order to make better use of recycled materials, ...
