Description
技术领域
本发明涉及热敏电阻领域,具体涉及一种热敏电阻器介质材料及其制备方法。
背景技术
近年,要求电子元件适应表面贴装,具有负温度特性的负温度系数热敏电阻也在开展片式化。现有的片式负温度系数热敏电阻使用温度范围主要在-40℃-125℃之间,端电极表面镀有锡层,以便在焊接电路过程中,可以采用回流焊工艺焊接在电路中。随着技术的发展,一些较高温度场合使用的负温度系数热敏电阻也出现了片式化需求,如激光打印机机头的温度控制需要在200℃-300℃温度范围内稳定使用的片式负温度系数热敏电阻。现有的片式负温度系数热敏电阻已不适用。首先,现有片式负温度系数热敏电阻的设计使用温度范围为-40℃-125℃,超过这一温度范围使用时,其常温阻值会随着使用时间产生较大的漂移,通常会超出10%。其次,在这个温度下,这种现有的负温度系数热敏电阻端电极的锡层容易融化,导致热敏电阻脱落而在电路中失去作用。
发明内容
针对现有技术的不足,本发明提供了一种热敏电阻器介质材料及其制备方法,能够提高使用寿命,成本低,使用效果显著。
为实现以上目的,本发明通过以下技术方案予以实现:
本发明提供了一种热敏电阻器介质材料,由以下重量份数的原料制备而成:BaTiO3:80-85份、Sb2O3:10-20份、Co2O3:5-12份、SrCO3:1-9份、MnO2:2-6份、Cr2O3:2-8份、SnO2:3-5份、SiO2:2-10份、CeO2:2-10份、ZrO2:2-8份、Y2O3:3-10份;
其制备方法为:
(1)首先按照重量份数称取Sb2O3、Co2O3、SrCO3、MnO2、Cr2O3、SnO2、SiO2、CeO2、ZrO2、Y2O3各组分原料,得到混合物料A,加入到重量为混合物料A 3倍的纯水中,并加入铵盐分散剂,所添加的铵盐分散剂的重量为混合物料A的0.8-1%;然后在球磨机中球磨2-3h,得到添加剂料浆;
(2)将主成分原料BaTiO3加入添加剂料浆中,搅拌至混合均匀,然后加入陶瓷粘结剂和聚乙烯醇溶液,混合均匀后得到喷雾料浆;
(3)采用离心式喷雾干燥塔将步骤(2)所得的喷雾料浆喷雾干燥,得到粉料;
(4)将步骤(3)所得的粉料通过干压方式成型,压制成坯体;
(5)将步骤(4)所得的坯体经排胶后,在温度为1000-1100℃的条件下烧结一段时间,获得热敏电阻器介质材料。
优选的,由以下重量份数的原料制备而成:BaTiO3:81-84份、Sb2O3:12-18份、Co2O3:6-11份、SrCO3:2-8份、MnO2:4-5份、Cr2O3:3-6份、SnO2:3-5份、SiO2:3-9份、CeO2:4-8份、ZrO2:3-5份、Y2O3:6-8份。
优选的,由以下重量份数的原料制备而成:BaTiO3:84份、Sb2O3:14份、Co2O3:6份、SrCO3:3份、MnO2:4份、Cr2O3:3份、SnO2:3份、SiO2:3份、CeO2:4份、ZrO2:4份、Y2O3:6份。
优选的,由以下重量份数的原料制备而成:BaTiO3:81份、Sb2O3:12份、Co2O3:10份、SrCO3:5份、MnO2:4份、Cr2O3:3份、SnO2:3份、SiO2:4份、CeO2:6份、ZrO2:3份、Y2O3:6份。
优选的,所述的制备方法步骤(3)中陶瓷粘结剂的量为主成分原料BaTiO3的5%。
优选的,所述的制备方法步骤(3)中烧结时间为5-7h。
本发明有益效果:
本发明的热敏电阻器介质材料,开机时热敏电阻为冷态低阻,通电后在电流作用下升温、阻值迅速提高,因它串在消磁线圈回路工作,所以消磁线圈就是开机瞬间有大的交流工作电流(消磁)很快由于热敏电阻的阻值增大(几十至数百千欧),消磁线圈中的工作电流几乎为零(相当于开路,不工作了,即消磁线圈只在冷态开机瞬间工作);其具有耐压高、残余电流小、功率低、使用安全、可靠性高、寿命长等特点。
