Abstract
本发明提供一种固体洁厕剂及制备方法，所述固体洁厕剂由聚乙二醇200、聚乙二醇4000、十二烷基苯磺酸钠、淀粉、硫酸钠、柠檬酸、色素、卡松、香精制备而成。制备方法是：反应釜加热升温至约90℃；边搅拌边加入聚乙二醇200、聚乙二醇4000、十二烷基苯磺酸钠、硫酸钠、淀粉、柠檬酸，冷却降温至约60℃后加色素、卡松、香精，得到混合物，混合物灌装、凝固即得成品。本发明有效成分含量高达45.5％，可强力清除脏污，有效防止黄垢、尿垢、水垢附着在马桶壁，对尿垢和尿碱尤为有效。本发明抑菌效果好：对细菌、病毒、真菌等有良好杀灭作用。此外，本发明还具有成本低，使用时间长的优点。
Description
技术领域
本发明属于日用化工领域，具体涉及一种固体洁厕剂及制备方法。
背景技术
抽水马桶自发明至今，为人类文明卫生进步做出突出贡献，在当今世界上，抽水马桶已被公认为"卫生水准的量尺"。随着社会的发展，城市化水平越来越高，城镇居住条件日益改善，抽水马桶已经普遍使用。极大方便人们生活的同时，也需要人们对其清洁卫生有足够的重视。因为马桶是排泄脏物的通道，在使用过程中容易积垢，且容易滋生细菌和产生异味，如果不做好清洗工作，很有可能成为威胁健康的罪魁祸首，引发诸多疾病，尤其是肠道疾病。故需要经常对马桶进行清洁除垢，例如用洁厕剂刷洗等。但这需要花费许多时间和精力，尤其对于上班族来说，工作繁忙，时间较少，需要更便捷的清洁除菌方式。
洁厕块或固体杀菌除臭剂是目前使用较为广泛的一种厕盆清洁剂，具有杀菌、除臭、清洗、防垢等多种功能，属自动清洗类。使用方法是，将洁厕块放入水箱中，缓慢溶解，释放杀菌剂、清洁剂，其中的有效成分随着每次冲厕时进入马桶，能够有效除垢、除味，达到保持厕盆洁净光亮、清洁杀菌，且除异味留清香的目的。洁厕块由于使用简单(直接投入水箱即可)、使用时间长(小小一块，可以长达数周)，更换标志显著(无色时提示需要添加)，且长期使用对器具及管道均无腐蚀性，因此，洁厕块越来越被人们接受并使用，市场应用广泛。
目前，市面上常用的洁厕块产品种类多，但是普遍存在使用周期短，残渣挂壁严重，尿垢难以清洗，易受潮变质等问题。因此，面对洁厕块或固体洁厕剂的广泛的市场需求，需要进一步改进提升产品的品质。
发明内容
本发明目的在于克服现有技术的不足，提供一种固体洁厕剂及制备方法，本发明洁厕剂适用于便盆清洁，具有清洁、除垢、抑菌、除味、增香等效果。
本发明技术方案如下，一种固体洁厕剂，按重量百分比计：聚乙二醇200 8％～12％，聚乙二醇4000 20％～30％，十二烷基苯磺酸钠10％～20％，淀粉15％～20％，硫酸钠15％～25％，柠檬酸5％～10％，色素1％～5％，卡松0.02％～0.1％，香精0.8％～1％。
优选地，本发明固体洁厕剂，按重量百分比计：聚乙二醇200 10％，聚乙二醇400025％，十二烷基苯磺酸钠15％，淀粉18％，硫酸钠20％，柠檬酸8％，色素3％，卡松0.05％，香精0.95％。
所述色素为本领域常用色素，包括但不限于：亮蓝色素、靛蓝色素、苋菜红色素、胭脂红色素、柠檬黄色素、日落黄色素其中的一种或几种；优选为亮蓝色素。
所述香精为本领域常用香精，例如花香型香精、非花香型香精、果香型香精；包括但不限于：柠檬香精、金桔香精、甜橙香精、薰衣草香精、松木香精、青苹果香精、玫瑰香精、菊花香精其中的一种或几种。
本发明固体洁厕剂组方是经过反复试验得出的，组方虽简单，然效果显著。本发明采用聚乙二醇200做溶剂，它无毒，无刺激，具有优良的分散性，粘结性，和其他组分有良好的相溶性。聚乙二醇4000作为凝固剂，与聚乙二醇200协同使用，起到调节产品的硬度、粘度的作用。十二烷基苯磺酸钠是一种阴离子型表面活性剂，其清洁去污力强，泡沫丰富，并且它对酸、碱，硬水性质稳定，生物降解性高，对环境污染性小，且价格低廉。淀粉在加热条件下糊化，起到粘合剂的作用，且取材容易。柠檬酸一方面可以调节产品的酸碱度，使其呈弱酸性，可以有效去除尿垢，预防尿碱的形成；另一方面，柠檬酸的加入还可以使淀粉凝胶的强度增加。
本发明固体洁厕剂的制备方法是：
(1)按用量称取各组分；反应釜加热升温至88℃～92℃，边搅拌边加入聚乙二醇200、聚乙二醇4000、十二烷基苯磺酸钠、硫酸钠、淀粉、柠檬酸，冷却降温至62℃～66℃后加色素、卡松、香精，得到混合物。
(2)反应釜和灌装设备保持恒温62℃～66℃，将混合物灌装、凝固即得成品。
使用时，将固体洁厕剂放入马桶水箱中即可。
本发明固体洁厕剂具有如下有益效果：
1、有效成分含量高，清洁去污力强：本发明有效成分含量高达45.5％，可强力清除脏污，有效防止黄垢、尿垢、水垢附着在马桶壁，本产品呈弱酸性，对尿垢和尿碱尤为有效。
2、抑菌效果好：对各种病毒、真菌、细菌及细菌繁殖体(例如芽孢)等有良好杀灭作用。
3、除异味：能够快捷消除卫生间臭味、异味，同时可散发自然清新的气味。
4、本发明组方简单、选料科学，与现有产品相比还具有成本更低、使用时间更长、对环境更友好的优点。常温下使用时间长达2～6个月。

试验例一、各实施例制备的样品理化指标检测
表1实施例1-4产品理化指标
其中，
有效物含量检测方法是：取试样5g(精确至0.001g)，重量记为M，加入约15ml蒸馏水搅拌至溶解，再加入50ml无水乙醇，搅拌至溶解完全。静置24h后用倾斜法过滤，清液尽量排干净，不溶物尽可能留在烧杯中，重复萃取过滤3次。将盛有含有少量乙醇和不溶物的烧杯(烧杯重量记为M0)置于沸水浴中，使乙醇蒸发完全，置于105℃烘箱中干燥1h，移入干燥器中，冷却称重,记为M1。计算方法：有效物含量X％＝(M1-M0)/M×100％。
稳定性检测：称取试样2份各100g，分别置于广口玻璃瓶中，一份于(50±1)℃的保温箱中放置24h，另一份于-(10±1)℃的冰箱中放置24h，取出恢复至室温后观察。
使用周期计算方法：分别将不同重量的固体洁厕块成品放入常规马桶水箱中，正常使用，测试使用周期。
结果表明：150克固体洁厕块成品常温下(25℃)可以用2个月，冲水达600-800次；330克固体洁厕块成品可以用6个月，冲水达1800-2000次。
试验例2、抑菌试验
从马桶内壁采集样本，平均分成四份，用本发明固体洁厕剂溶液处理样本，处理前后比较结果见表2：
表2本发明固体洁厕剂处理前后的菌落总数比较(cfu/cm2)
| 处理前(菌落总数) | 处理后(菌落总数) | 除菌率 | |
| 实施例1样品 | 920 | 17 | 98.2％ |
| 实施例2样品 | 922 | 20 | 97.8％ |
| 实施例3样品 | 919 | 16 | 98.3％ |
| 实施例4样品 | 920 | 19 | 97.9％ |
试验例3、毒性及刺激性试验
