Abstract

本申请公开了一种水敏变色涂料,包括松香250-290份,钼酸铵200-300份,草酸200-260份,1-氨基-2-苯酚-4-磺酸50-90份,亚硫酸1300-1700份,盐酸25-45份,甲醇600-700份,二氧化钛140-180份,由此,与水接触后,涂料由蓝色变成粉白色,提高了灵敏度。

Description

一种水敏变色涂料
技术领域
本发明涉及化学涂料,尤其涉及一种水敏变色涂料。
背景技术
水敏变色材料是变色材料的研究和应用领域的重要内容。目前,水敏变色材料的感湿有对液态水的,也有对空气中的水汽的。现在虽然发展了一些水敏材料,但就作用原理和应用情况都还存在一些不足,例如。很多变色材料含有对人体有害的有机物,另外就是现有的水敏变色材料的变色速度要么太快,要么过慢,这对于通过变色材料的变色来检测空气湿度变化是很困难的。
发明内容
本发明的目的提供一种水敏变色涂料,解决上述现有技术问题中的一个或者多个。
根据本发明的一个方面,提供一种水敏变色涂料,包括松香250-290份,钼酸铵200-300份,草酸200-260份,1-氨基-2-苯酚-4-磺酸50-90份,亚硫酸1300-1700份,盐酸25-45份,甲醇600-700份,二氧化钛140-180份。
生产时,先将钼酸铵、8/10份草酸和1-氨基-2-苯酚-4-磺酸加入由亚硫酸(8%)、盐酸(18%)组成的溶液中,搅拌反应,生成沉淀,分离。将沉淀物溶于由松香、剩余的草酸和甲醇所组成的溶液中溶解完全后,加入16份二氧化钛,充分调和均匀,过滤得到水敏变色涂料。
本发明与水接触后,涂料由蓝色变成粉白色,提高了灵敏度。
具体实施方式
实施例1:包括松香250份,钼酸铵200份,草酸200份,1-氨基-2-苯酚-4-磺酸50份,亚硫酸1300份,盐酸25份,甲醇600份,二氧化钛140份。
实施例2:包括松香270份,钼酸铵250份,草酸230份,1-氨基-2-苯酚-4-磺酸70份,亚硫酸1500份,盐酸35份,甲醇650份,二氧化钛160份。
实施例3:包括松香290份,钼酸铵300份,草酸60份,1-氨基-2-苯酚-4-磺酸90份,亚硫酸1700份,盐酸45份,甲醇700份,二氧化钛180份。
生产时,先将钼酸铵、8/10份草酸和1-氨基-2-苯酚-4-磺酸加入由亚硫酸(8%)、盐酸(18%)组成的溶液中,搅拌反应,生成沉淀,分离。将沉淀物溶于由松香、剩余的草酸和甲醇所组成的溶液中溶解完全后,加入16份二氧化钛,充分调和均匀,过滤得到水敏变色涂料。
综上所述,本发明与水接触后,涂料由蓝色变成粉白色,提高了灵敏度。
以上所述仅是本发明的一种实施方式,应当指出,对于本领域普通技术人员来说,在不脱离本发明创造构思的前提下,还可以做出若干相似的变形和改进,这些也应视为本发明的保护范围之内。
