Description

一种防紫外线玻璃及其制备方法 技术领域
本发明涉及玻璃，尤其涉及一种防紫外线玻璃及其制备方法。
背景技术
玻璃：一种透明的半固体，半液体物质，在熔融时形成连续网络结构，冷却过程中粘度逐渐增大并硬化而不结晶的硅酸盐类非金属材料。普通玻璃化学氧化物的组成(Na2O·CaO·6SiO2)，主要成分是二氧化硅。广泛应用于建筑物，用来隔风透光，属于混合物。另有混入了某些金属的氧化物或者盐类而显现出颜色的有色玻璃，和通过特殊方法制得的钢化玻璃等。有时把一些透明的塑料(如聚甲基丙烯酸甲酯)也称作有机玻璃。
玻璃是一种无规则结构的非晶态固体(从微观上看，玻璃也是一种液体)，其分子不像晶体那样在空间具有长程有序的排列，而近似于液体那样具有短程有序。玻璃像固体一样保持特定的外形，不像液体那样随重力作用而流动。
玻璃态物质一般是由熔融体快速冷却而得到，从熔融态向玻璃态转变时，冷却过程中黏度急剧增大，质点来不及做有规则排列而形成晶体，没有释出结晶潜热，因此，玻璃态物质比结晶态物质含有较高的内能，其能量介于熔融态和结晶态之间，属于亚稳状态。从力学观点看，玻璃是一种不稳定的高能状态，比如存在低能量状态转化的趋势，即有析晶倾向，所以，玻璃是一种亚稳态固体材料。
玻璃生产的主要原料有玻璃形成体、玻璃调整物和玻璃中间体，其余为辅助原料。主要原料指引入玻璃形成网络的氧化物、中间体氧化物和网络外氧化物；辅助原料包括澄清剂、助熔剂、乳浊剂、着色剂、脱色剂、氧化剂和还原剂等。
传统的玻璃工艺配方简单，没有防紫外线的功能。
