(1) 강화 플라스틱의 노화 방지 특성

폴리머의 노화 방지 특성은 서비스 수명과 환경, 특히 높은주의가 필요한 지표 인 농업용 플라스틱 및 플라스틱 건축 자재의 경우 직접적으로 영향을 미칩니다. 280 ~ 400nm 대역의 자외선은 폴리머의 분자 사슬을 깨뜨리고 재료를 노화시키지 않습니다. 과 같은 나노 산화물 알루미나 나노 분말, 산화 티탄 나노 분말, 실리콘 산화물 나노 분말 등은 적외선과 마이크로파에 대해 좋은 흡수 특성을 가지며 nano-sio2와 tio2를 적절히 혼합하여 다량의 자외선을 흡수 할 수있어 노화에 강합니다.

(2) Improve the processing properties of plastics
Some high-polymers such as ultra-high molecular weight polyethylene having a viscosity average molecular weight of 150 or more have excellent comprehensive performance, but because of their extremely high viscosity, molding processing is difficult, thereby limiting the promotion. Utilizing the small coefficient of friction between layers of layered silicate sheets, the ultra-high molecular weight polyethylene and the layered silicate are thoroughly mixed to form a nano rare earth/ultra high molecular weight polyethylene composite material, which can effectively reduce ultra high molecular weight poly The entanglement of the ethylene molecular chain reduces the viscosity and provides good lubrication, which greatly improves the processing properties.

(3) Improve the toughness and strength of plastics
The emergence of nanomaterials provides a new method and approach for plastic reinforcement and toughening modification. The small particle size dispersed phase has relatively few surface defects and many unpaired atoms. The ratio of the number of surface atoms to the total number of atoms of a nanoparticle increases sharply as the particle size becomes smaller. The crystal field environment and binding energy of the surface atom are different from those of the internal atom, and have great chemical activity. The atomization of the crystal field and the increase of the active surface atoms greatly increase the surface energy, so that it can be closely combined with the polymer substrate, and the compatibility is better. When subjected to an external force, the ions are not easily detached from the substrate, and the external stress that is received is better transmitted. At the same time, under the interaction of the stress field, more microcracks and plastic deformation will be generated inside the material, which can cause the substrate to yield and consume a large amount of impact energy, thereby achieving the purpose of simultaneously strengthening and toughening. Commonly used nano materials include nano silicon carbide, silicon carbide whiskers, nano alumina, multi-wall carbon nanotubes and the like.

(4) The addition of nanomaterials functionalizes plastics

Metal nanoparticles have heterogeneous nucleation and can induce the formation of certain crystal forms that impart toughness to the material. Filling the polypropylene with low-melting metal nanoparticles shows that it can act as a conductive channel and enhance and toughen in polypropylene, and its low melting point also improves the processing properties of the composite.
