聚丙烯改性材料

聚丙烯物理改性

在混合和混合过程中，向聚丙烯（PP）基体中添加有机或无机添加剂，以获得性能优异的PP复合材料，主要包括：填充改性、共混改性等。（1）填充改性在PP成型过程中，向聚合物中填充硅酸盐、碳酸钙、二氧化硅、纤维素、玻璃纤维等填料，以提高PP的耐热性，降低成本，增加刚性，减少成型收缩。然而，PP的冲击强度和延伸率会相应降低

共混改性

将聚丙烯（PP）与聚乙烯、工程塑料、热塑性弹性体或橡胶等共混，以达到改善PP性能的改性方法。共混改性在内混机、开式磨机、挤出机等加工设备中完成。工艺易于调整，生产周期短，而且成本很低。它可以改善PP的着色性、加工性、抗静电性和耐冲击性等多种性能

增强改性塑料中加入纤维材料可以显著提高塑料材料的强度，因此被称为增强改性。大径厚比的材料可以显著提高塑料材料的弯曲模量（刚度），这也可以称为增强改性

PP modified material

PP physical modification

In the process of mixing and mixing, organic or inorganic additives are added to the polypropylene (PP) matrix to obtain PP composite materials with excellent performance, which mainly include: filling modification, blending modification, etc.

(1) Filling modification

In the PP molding process, fillers such as silicate, calcium carbonate, silicon dioxide, cellulose, glass fiber, etc. are filled into the polymer to improve the heat resistance of PP, reduce costs, increase rigidity, and reduce molding shrinkage. However, the impact strength and elongation of PP will decrease accordingly.

(2) Blending modification

Blending polypropylene (PP) with polyethylene, engineering plastics, thermoplastic elastomers or rubber, etc., to achieve a modification method to improve the performance of PP. Blending modification is completed in processing equipment such as internal mixers, open mills, extruders, etc. The process is easy to adjust, the production cycle is short, and the cost is low. It can improve the coloring, processability, antistatic and resistance of PP. Various properties such as impact.

(3) Enhanced modification

The addition of fibrous materials to plastics can significantly increase the strength of plastic materials, so it is called enhanced modification. Materials with a large diameter-to-thickness ratio can significantly increase the flexural modulus (rigidity) of plastic materials, which can also be called enhanced modification.
