摘　　要：厚度为0.55 mm的平板锂铝硅玻璃,在KNO_(3)/NaNO_(3)混合熔盐中进行第1步化学钢化(IOX1),以及在KNO_(3)/NaNO_(3)/CuSO_(4)混合熔盐中进行第2步化学钢化(IOX2),可获得强度高、透明度好、抑菌效果优良的铜基抗菌玻璃。研究不同质量分数的CuSO4对锂铝硅玻璃抗菌性能的影响,结果表明,当工艺条件为:第1步离子交换混盐质量比为w(KNO_(3))∶w(NaNO_(3))=50∶50、交换4 h,第2步离子交换混盐质量比为w(KNO_(3))∶w(NaNO_(3))∶w(CuSO_(4))=90∶5∶5、交换2.5 h,可获得表面应力值高于700 MPa、在可见光区透过率>90%、抗菌活性值R≥5的优质抗菌玻璃。Copper-base antibacterial glass with high strength,good transparency,and excellent antibacterial effect was prepared by dipping 0.55mm flat lithium aluminum silicate glass in a mixture of KNO_(3)/NaNO_(3) molten salt as the first step of chemical tempering(IOX1)and KNO_(3)/NaNO_(3)/CuSO_(4) mixed molten salt as the second step of chemical tempering(IOX2).The effect of different ratio of CuSO4 on the antibacterial properties of the glass was investigated.The results showed that the first step was to exchange in the mixed salt with mass ratio w(KNO_(3))∶w(NaNO_(3))was 50∶50 by soaking for 4 hours.In the second step,the mass ratio of mixed salt for ion exchange w(KNO_(3))∶w(NaNO_(3))∶w(CuSO_(4))was 90∶5∶5,and the soaking time was 2.5 hours.Under this process condition,the excellent antibacterial glass with a surface stress value more than 700 MPa,a transmittance of over 90%in the visible light region and an antibacterial activity value R≥5 can be obtained.
