Description
技术领域technical field
本发明属于高韧聚合物共混物合金的制备技术领域。The invention belongs to the technical field of preparation of high toughness polymer blend alloys.
背景技术Background technique
聚碳酸酯(Polycarbonate,PC)是一种分子链中含有碳酸酯基的聚合物，包括脂肪族、脂肪族-芳香族以及芳香族PC材料。而芳香族聚碳酸酯中的双酚A型聚碳酸酯由于具有较好的机械性能，高的热变形温度、良好的抗蠕变性、尺寸稳定性以及良好的电绝缘性能，在工程材料领域得到了广泛的应用。但由于双酚A型聚碳酸酯本身对缺口比较敏感、缺口冲击强度低；虽然可以通过改性来改善其缺点，但双酚A型聚碳酸酯与其他聚合物共混时相容性较差，因此其应用受到了限制。因此双酚A型聚碳酸酯材料的冲击性能，提高材料的韧性是目前急需解决的问题。Polycarbonate (Polycarbonate, PC) is a polymer containing carbonate groups in the molecular chain, including aliphatic, aliphatic-aromatic and aromatic PC materials. The bisphenol A polycarbonate in the aromatic polycarbonate has good mechanical properties, high heat distortion temperature, good creep resistance, dimensional stability and good electrical insulation performance, and is widely used in the field of engineering materials. Has been widely used. However, because bisphenol A polycarbonate itself is sensitive to notches and has low notched impact strength; although its shortcomings can be improved by modification, bisphenol A polycarbonate has poor compatibility when blended with other polymers , so its application is limited. Therefore, the impact performance of bisphenol A polycarbonate material and improving the toughness of the material are urgent problems to be solved at present.
目前，改性方法主要分为两种，一种是依靠大分子主链、支链或侧链结构的变化实现改性，虽然经化学改性的PC改性效果较好，但是改性过程可操作性小，并且成本较高，因此应用相对较少。其次可利用不同组分之间的物理作用(如吸附、络合或氢键等作用)以及整个组分本身的形态变化来达到改性目的。对双酚A型聚碳酸酯的物理改性方法主要包括，填充改性和聚合物共混物两种。为了改善双酚A型聚碳酸酯某一方面的性能或者降低其生产成本，多数情况下会向双酚A型聚碳酸酯中添加比例不同的无机粉体或纤维等填充剂进行改性，其中玻璃纤维的应用最为广泛。与纯双酚A型聚碳酸酯相比，玻璃纤维增强双酚A型聚碳酸酯具有强度高，刚性大，耐应力开裂性好，耐热性高和电性能好等优点，但是玻璃纤维增强双酚A型聚碳酸酯在刚性、强度提高的同时，冲击强度显著下降。另一方面，随着纳米技术的发展，纳米复合技术已经成为双酚A型聚碳酸酯的新型改性方法。为了改善双酚A型聚碳酸酯的性能，可将其与一些无机填料，如二氧化硅、氧化锌、蒙脱土、碳纳米管、炭黑、粘土等进行复合，从而使机械性能、电学性能、热性能等得到改善，但是这往往依赖于纳米填料的分散以及与基体之间的相互作用，因此冲击强度的改善较为有限。与另一种聚合物共混也是提高双酚A型聚碳酸酯冲击韧性的有利手段，可以提高材料的抗冲击性能；但简单的共混物材料物理和力学性能不稳定，制品易出现相分离，低温抗冲击性能较差。At present, the modification methods are mainly divided into two types. One is to rely on changes in the structure of the main chain, branch chain or side chain of the macromolecule to achieve modification. Although the modification effect of chemically modified PC is better, the modification process can be The operability is small and the cost is high, so there are relatively few applications. Secondly, the physical interaction between different components (such as adsorption, complexation or hydrogen bonding, etc.) and the morphological change of the entire component itself can be used to achieve the purpose of modification. The physical modification methods of bisphenol A polycarbonate mainly include filling modification and polymer blending. In order to improve the performance of a certain aspect of bisphenol A polycarbonate or reduce its production cost, in most cases, fillers such as inorganic powders or fibers in different proportions will be added to bisphenol A polycarbonate for modification. Fiberglass is the most widely used. Compared with pure bisphenol A polycarbonate, glass fiber reinforced bisphenol A polycarbonate has the advantages of high strength, high rigidity, good stress crack resistance, high heat resistance and good electrical properties, but glass fiber reinforced While the rigidity and strength of bisphenol A polycarbonate are improved, the impact strength is significantly reduced. On the other hand, with the development of nanotechnology, nanocomposite technology has become a new modification method of bisphenol A polycarbonate. In order to improve the performance of bisphenol A polycarbonate, it can be compounded with some inorganic fillers, such as silicon dioxide, zinc oxide, montmorillonite, carbon nanotubes, carbon black, clay, etc., so that the mechanical properties, electrical properties Performance, thermal properties, etc. are improved, but this often depends on the dispersion of nanofillers and the interaction with the matrix, so the improvement in impact strength is relatively limited. Blending with another polymer is also a favorable means to improve the impact toughness of bisphenol A polycarbonate, which can improve the impact resistance of the material; but the physical and mechanical properties of the simple blend material are unstable, and the product is prone to phase separation , low temperature impact resistance is poor.

Due to the high strength of carbon nanotubes, the π-π interaction between carbon nanotubes and bisphenol A polycarbonate is beneficial to improve the tensile properties of the alloy. At the same time, the selective uniform dispersion of carbon nanotubes in the bisphenol A polycarbonate matrix changes the phase domain size of bisphenol A polycarbonate, increases the phase domain of bisphenol A polycarbonate, and also has It is beneficial to the improvement of the impact performance of the alloy. Secondly, through the compatibilization effect of the compatibilizer on the incompatible bisphenol A polycarbonate and the modified polymer, the combination of the modified polymer and the bisphenol A polycarbonate is strengthened, and the toughness and tensile strength of the material are improved again. extensibility.

Experiments have proved that after adding carbon nanotubes and compatibilizer at the same time, the impact strength of bisphenol A polycarbonate/polylactic acid mixture alloy at room temperature From 13.4kJ/m 2 the maximum can be increased to 87.1kJ/m 2 , while the impact strength at low temperature (0°C) can be increased from 7.5kJ/m 2 to 40.0kJ/m 2 . And its tensile strength changes Small range.
