Description
纳米聚丙烯组合物 技术领域 Nano-polypropylene composition
本发明属于聚丙烯技术领域, 尤其涉及一种改进的纳米聚丙烯组合物。 The invention belongs to the field of polypropylene technology, and in particular to an improved nano-polypropylene composition.
背景技术 Background technique
聚丙烯的结晶度高, 结构规整, 因而具有优良的力学性能。 但在室温和低温下, 由 于本身的分子结构规整度高, 所以冲击强度较差。 聚丙烯最突出的性能就是抗弯曲疲劳 性。聚丙烯具有良好的耐热性, 制品能在 10CTC以上温度进行消毒灭菌, 在不受外力的条 件下, 150°C也不变形。 脆化温度为 -35°C, 在低于 -35°C会发生脆化, 耐寒性不如聚乙烯。 聚丙烯的化学稳定性很好, 除能被浓硫酸、 浓硝酸侵蚀外, 对其它各种化学试剂都比较 稳定; 但低分子量的脂肪烃、 芳香烃和氯化烃等能使聚丙烯软化和溶胀, 同时它的化学 稳定性随结晶度的增加还有所提高, 所以聚丙烯适合制作各种化工管道和配件, 防腐蚀 效果良好。 聚丙烯的高频绝缘性能优良, 由于它几乎不吸水, 故绝缘性能不受湿度的影 响。 它有较高的介电系数, 且随温度的上升, 可以用来制作受热的电气绝缘制品。 它的 击穿电压也很高, 适合用作电气配件等。 抗电压、 耐电弧性好, 但静电度高, 与铜接触 易老化。 聚丙烯对紫外线很敏感, 加入氧化锌、 硫代二丙酸二月桂酯、 碳黑或类似的乳 白填料等可以改善其耐老化性能。传统通用级的 PP存在很多缺点,如强度低,收縮率大, 易翘曲, 耐温差, 耐化学性和光稳定性差等诸多缺陷。 但传统的 PP也有透明性好, 价格 低廉的有点, 主要应用在一些大众的日常用品上, 特别是可进行后续的改性造粒加工。 发明内容 Polypropylene has high crystallinity and regular structure, and thus has excellent mechanical properties. However, at room temperature and low temperature, the impact strength is poor due to the high degree of molecular structure regularity. The most outstanding property of polypropylene is its resistance to bending fatigue. Polypropylene has good heat resistance, and the product can be sterilized at a temperature above 10CTC, and it is not deformed at 150 °C under the condition of no external force. The embrittlement temperature is -35 ° C, embrittlement occurs below -35 ° C, and the cold resistance is not as good as polyethylene. Polypropylene has good chemical stability, and it is stable to various other chemicals except for concentrated sulfuric acid and concentrated nitric acid. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften polypropylene and Swelling, and its chemical stability is also improved with the increase of crystallinity, so polypropylene is suitable for making various chemical pipes and fittings with good anti-corrosion effect. Polypropylene has excellent high-frequency insulation properties, and since it hardly absorbs water, the insulation properties are not affected by humidity. It has a high dielectric constant and can be used to make heated electrical insulation products as temperature rises. It also has a high breakdown voltage and is suitable for use as an electrical accessory. It has good resistance to voltage and arc resistance, but it has high static electricity and is easily aged in contact with copper.
