ZnO对ZnO-B2O3-SiO2玻璃结构和性能的影响毕业论文

 2021-06-08 00:19:14  

摘 要

在日常生活中,硼硅酸盐玻璃由于其良好的性能从而得到了广泛的应用,但是随着科学技术的快速发展,普通的硼硅酸盐玻璃已经不能满足在光电、核能、通信、航天航空等高端领域中的需求。基于这些领域的需求,具有良好性能的硼硅酸盐玻璃逐渐进入了人们的视线。锌硼硅玻璃是其中的一种,由于其易于存放和加工,熔点低,在封接材料领域、发光材料领域、光储存材料领域以及喷墨打印等领域的研究已得到关注。

论文主要研究ZnO的引入量变化对ZnO-B2O3-SiO2玻璃结构和性能的影响,以确定合适的ZnO引入量。通过红外光谱分析了ZnO-B2O3-SiO2玻璃在不同ZnO含量下的结构变化,测试了玻璃的热膨胀系数、转变温度、软化温度、高温接触角,探究ZnO-B2O3-SiO2玻璃在不同ZnO含量下结构与性能的变化。

研究结果表明:(1)随着ZnO含量的增加,玻璃结构中的[BO3]的数量不断增多,[BO4]的数量在不断减少;随着ZnO含量的增加,SiO2含量的减少,460cm-1处峰的强度逐渐减弱,这是由于SiO2量的减少使得[SiO4]的数量减少;而随着ZnO量的增加,[ZnO4]数量也增加,虽然其基团振动频率弱,但是由于其数量多,还是在A0样中检测到了[ZnO4]中的Zn-O振动峰。(2)热膨胀和DSC分析结果表明:随着玻璃中ZnO含量的增加,SiO2含量的减少,导致玻璃结构中[BO3]增多,[BO4]减少,[ZnO4]增多,[SiO4]减少,从而使得转变温度Tg和软化温度Tf都降低,降低趋势比较明显;由于[BO3]增多,[BO4]减少,[BO4]与硅氧网络的连接程度减弱,因此玻璃的热膨胀系数逐渐增大,而[ZnO4]数量增多且体积较[SiO4]体积大,也会导致热膨胀系数会增大。(3)超高温接触角的结果在一定程度上验证了热膨胀和DSC测定的玻璃软化点的数值结果,其间接证明了锌硼硅玻璃低熔点的性能。

本文的特色:在研究了ZnO含量对锌硼硅玻璃结构和性能的影响之后,还选取了性能较好的两组配方的玻璃做了玻璃粉和蓝色色料复合烧结性能测试,烧制结果表明玻璃粉能够在580℃熔化,且能在基底玻璃上形成透明的玻璃层。对涂覆层做了XRD、硬度、光泽度、耐酸碱等测试,结果表明,涂覆层烧结后依然为玻璃呈透明状,硬度较大,光泽度较差,耐酸性较差,耐碱性较好。

Abstract

In daily life, borosilicate glass which has been widely used due to its good performance, but with the rapid development of science and technology, Ordinary borosilicate glass cannot have satisfied in the field of photoelectricity, nuclear energy, communications, aerospace and other high-end requirements. Based on the requirement of these areas,the borosilicate glass come into the sight of people. Zinc borosilicate glass is one of them, because of its easy to storage and processing, low melting point,which in the field of sealing materials, luminescence materials, optical storage materials, and ink-jet printing areas' research has been focused on.

Paper mainly studies the impact of introduction of the ZnO variation on structure and properties of ZnO-B2O3-SiO2 glass, to determine the appropriate amount of ZnO. By infrared spectroscopy of ZnO-B2O3-SiO2 glass structure change under different ZnO content, testing the thermal expansion coefficient of glass transition temperature, soften temperature and high temperature contact Angle and chemical stability, and to explore the structure and performance of ZnO-B2O3-SiO2 glass under the different content of ZnO.

The results show that: (1) with the increase of ZnO content, glass structure of the growing number of [BO3], [BO4] in a decreasing number of; With the increase of ZnO content, SiO2 content decreases, the strength of the peak at 460 cm-1 gradually weakened, this is due to the amount of SiO2 reduction made [SiO4] to reduce the number of; And with the increment of ZnO, [ZnO4] quantity will increase, while the group vibration frequency is weak, but because of its quantity, or in A0 samples detected in [ZnO4] Zn-O vibration peak. (2) the thermal expansion and DSC analysis results show that with the increase of ZnO content in the glass, the reduce of the content of SiO2, which results in the glass structure [BO3], [BO4], [ZnO4], [SiO4] is reduced, so as to make the transition temperature Tg and softening temperature Tf are lower, reduce trend is obvious; Because [BO3], [BO4], [BO4] with the silica network connection degree reduced, therefore the thermal expansion coefficient of glass increases gradually, and [ZnO4] the rise in the Numbers and volume is [SiO4] volume is big, can also lead to thermal expansion coefficient increases. (3) the result of the contact Angle ultra high temperature to a certain extent, to verify the thermal expansion and the glass to softening point of the numerical results of DSC test, the indirect proof the performance of the low melting zinc borosilicate glass.

In this paper, after studying the ZnO content on the zinc borosilicate glass structure and properties, the influence of two groups of glass powder is also chosen the coating performance testing, firing results show that the glass beads to melt at 580 ℃, and can form a transparent glass layer on the substrate glass. XRD is carried out for the coating layer, hardness, gloss, resistance to acid and alkali, such as testing, results show that the coating layer is still after sintering glass is transparent, hardness, glossiness is poorer, poor resistance to acid, alkali resistance is better.
