Description
技术领域
本发明涉及物体表面消毒剂技术领域,尤其涉及一种长效自消杀物表消毒剂及其制备方法与应用。
背景技术
研究发现某些病毒在光滑物体表面,有可能存活达到5天,所以日常清洗消杀非常重要。同时,以空调为例,中央空调通风系统需严格进行清洗消毒,防止回风带来交叉污染。
另一方面,公共场所集中空调通风系统清洗规范和卫生管理条例明文规定:空调清洗和消杀作业后,细菌总数、真菌总数的去除率应不低于90%;根据相关部门规定:办公场所和公共场所必须保持通风,开启空调必须按照相关规定,每周进行清洗消毒作业,检测合格后方可投入使用。
但是,当前常规的消毒技术,包括酒精、含氯化合物、双氧水等都只有一次性消毒能力,当消毒剂挥发后消毒能力便消失。
因此,现有物表消毒技术还有待于改进和发展。
发明内容
鉴于上述现有技术的不足,本发明的目的在于提供一种长效自消杀物表消毒剂及其制备方法与应用,旨在解决现有物表消毒技术仅有一次性消毒能力,消毒剂挥发后消毒能力便消失的问题。
为了解决上述技术问题,本发明为解决上述技术问题所采用的技术方案如下:
一种长效自消杀物表消毒剂,其中,按重量百分比计,包括:
酒精85%-98%;
粘结剂0.5%-5%;
固体消杀材料0.5%-10%;
助剂0.1%-1%。
所述的长效自消杀物表消毒剂,其中,所述酒精为体积分数不低于75%的酒精。
所述的长效自消杀物表消毒剂,其中,所述粘结剂为PVA、PVB中的至少一种。
所述的长效自消杀物表消毒剂,其中,所述固体消杀材料为压电催化材料、纳米银颗粒、可见光催化材料、氧化亚铜、胍类消毒剂、季氨盐类、过硫酸纳中的一种或多种。
所述的长效自消杀物表消毒剂,其中,所述压电催化材料为CuO、ZnO、BaTiO3、MoS2中的一种或多种。
所述的长效自消杀物表消毒剂,其中,所述可见光催化材料为WO3、Ag3PO4、 BiVO4、g-C3N4、黑色TiO2、Bi2WO6、Bi2MoO6中的一种或多种。
所述的长效自消杀物表消毒剂,其中,所述助剂为分散剂。
所述的长效自消杀物表消毒剂,其中,所述助剂为偏磷酸钠。
一种如本发明上述方案所述的长效自消杀物表消毒剂的制备方法,其中,包括步骤:
向酒精中加入粘结剂,搅拌溶解;
加入固体消杀材料,搅拌至完全分散,封装,制得所述长效自消杀物表消毒剂。
一种如本发明上述方案所述的长效自消杀物表消毒剂用于对物体表面消毒的应用。
有益效果:本发明公开了一种长效自消杀物表消毒剂及其制备方法与应用,该长效自消杀物表消毒剂按重量百分比计,包括:酒精85%-98%;粘结剂0.5%-5%;固体消杀材料0.5%-10%;助剂0.1%-1%。采用本发明的长效自消杀物表消毒剂可以对空调等物体表面进行有效消毒,即使酒精挥发后,被喷涂的区域依然具有自消杀的能力,自消杀能力的寿命不低于1年。

具体实施方式
为使本发明的目的、技术方案及优点更加清楚、明确,以下参照附图并举实施例对本发明进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
还是以空调为例,当前常规的物体表面消毒技术,包括酒精、含氯化合物、双氧水等都只有一次性消毒能力,当消毒剂挥发后消毒能力便消失。
为了解决现有技术中的问题,本发明提供一种长效自消杀物表消毒剂,其中,按重量百分比计,包括:
酒精85%-98%;
粘结剂0.5%-5%;
固体消杀材料0.5%-10%;
助剂0.1%-1%。
具体地,本发明以酒精作为粘结剂和固体消杀材料的载体,当毒剂被喷射在空调滤网、盖板、风管上后,可对其进行有效消毒,酒精挥发后,固体消杀材料被粘结剂粘结在空调的表面,因配方中的固体消杀材料能够对其周围进行一定距离的消杀,从而使被喷涂的区域具有自消杀的能力,并且自消杀能力的寿命不低1年,同时酒精除了作为载体外,其自身也就有消毒能力,能够在所述消毒剂被喷射到空调滤网、盖板、风管上时,也能够起到一段时间的消毒能力。
在一些实施方式中,所述酒精为体积分数不低于75%的酒精,通过选用体积分数不低于75%的酒精能够大幅提高消毒剂对于空调等物体表面的消毒能力。
在一些实施方式中,所述粘结剂为PVA(聚乙烯醇)、PVB(聚乙烯醇缩丁醛酯)中的至少一种。
本实施例中优选PVB作为粘结剂,所述粘结剂主要是为了能够起到粘结作用,使消毒剂能够更好地粘结在空调表面上,并且即使消毒剂中的酒精挥发,也可通过粘结剂将固体消杀材料粘结在空调表面,从而继续维持被喷涂区域的自消杀能力。
在一些实施方式中,所述固体消杀材料为压电催化材料、纳米银颗粒、可见光催化材料、氧化亚铜中的一种或多种。
在一些实施方式中,所述压电催化材料为CuO、ZnO、BaTiO3、MoS2中的一种或多种。
压电催化是利用压电材料捕获机械能来驱动表面催化化学反应,压电催化产生活性氧成分(ROS)可以杀灭细菌和降解有机物。
在一些实施方式中,所述可见光催化材料为WO3、Ag3PO4、BiVO4、g-C3N4、黑色 TiO2、Bi2WO6、Bi2MoO6中的一种或多种。
在一些实施方式中,固体消杀材料还包括胍类消毒剂,季氨盐类,过硫酸纳等。

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例,仅在于说明本发明而决不限制本发明。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
实施例1固体消杀材料的制备:
本实施例中的固体消杀材料为氧化铜氧化锌复合压电催化材料,具体制备方法为:将2L浓度为36mg/ml的氢氧化钠溶液,升温至45℃,加入80g石油磺酸钾搅拌溶解均匀。配置2L 含60mg/ml硫酸铜、含60mg/ml硫酸锌的铜锌溶液。将铜锌溶液缓慢滴加至含十二烷基苯磺酸钠的氢氧化钠溶液中,滴加时长约1h。调节最终滴加后溶液pH为中性。升温至95℃反应0.5h。将反应产物反复离心清洗、晾干即得到氧化铜氧化锌复合压电催化材料。
制得的氧化铜氧化锌复合压电催化材料的电镜图片如图2所示,由图2可以看出,制得的氧化铜氧化锌复合压电自消杀材料中的氧化铜、氧化锌具有柱状针状复合异质结结构,其中氧化铜显柱状结构,氧化锌显针状结构。
实施例2长效自消杀物表消毒剂的制备:
将3g的PVB粉末溶于100ml的75%酒精,搅拌约30min完全溶解,加入2g实施例1中制得的氧化铜氧化锌复合压电催化材料,继续搅拌15分钟直至完全分散,封装得到长效自消杀物表消毒剂。
实施例3长效自消杀物表消毒剂喷涂后自消杀能力验证:
用实施例2配置的长效自消杀物表消毒剂对尼龙空调滤网进行喷洒,置于空气中室温下晾干。随后,采用抑菌圈实验测试尼龙空调滤网的自消杀能力。先取大肠杆菌培养液(约1.0 ×106CFU/ml)涂布在营养琼胶平板上,在板上分别放上2块喷洒后的尼龙空调网,在避光下,不经过任何处理,放入培养箱中经过24小时培养,取出测量其抑菌圈约为1.0cm。
具体实验图片可参照图3,由图3可以看出,喷洒后的尼龙空调网可对其材料周边产生自消杀功能。
实施例4长效自消杀物表消毒剂的长效自消杀能力检验:
将实施例2所配置的长效自消杀物表消毒剂,委托给第三方检测机构(例如中营质检科技股份有限公司)按照《消毒技术规范》(2002年版)进行检验,送检样品(物表消毒剂,批号为15220001)的pH值均值为8.17,经气相色谱法检测的乙醇含量为77.1%,且置54℃恒温恒湿箱储存14天后,送检样品的乙醇含量为75.2%,下降率为2.5%,试验结果符合《消毒技术规范》(2002年版)的要求,该产品贮存有效期可定为1年。
检验结论表明,送检样品(物表消毒剂,批号为15220001)对不锈钢基本无腐蚀,对碳钢中度腐蚀,对铝和铜基本无腐蚀;对金黄色葡萄球菌平均杀灭对数值≥5.00,对大肠杆菌平均杀灭对数值≥5.00,对铜绿假单胞菌平均杀灭对数值均≥5.00,对白色念珠菌平均杀灭对数值均≥4.00,对人工染菌物体表面上大肠杆菌的平均杀灭对数值≥3.00,均符合《消毒技术规范》(2002年版)的相关要求,消毒合格;D/E中和肉汤中和剂和产物可有效中和送检样品对金黄色葡萄球菌或白色念珠菌的抑制作用,且D/E中和肉汤中和剂和产物对受试菌(金黄色葡萄球菌或白色念珠菌)生长及培养无影响。
另外,毒理实验表明,送检样品(物表消毒剂,批号为15220001)采用经口毒性试验属实际无毒,采用家兔一次完整皮肤刺激试验属无刺激性,以及采用经口灌胃30h染毒法,用小鼠骨髓嗜多染红细胞微核试验呈阴性,均符合《消毒技术规范》(2002年版)的相关要求,无毒、无刺激性。
实施例5长效自消杀物表消毒剂的抗人体冠状病毒测试:
将实施例2所配置的长效自消杀物表消毒剂,委托给第三方检测机构(例如飞凡标准技术服务(苏州)有限公司)按照ISO 18184:2019Textiles Determination ofantiviral的检测依据和方法进行抗病毒活性试验HCoV-229E检测,将长效物表消毒剂(批号为15220001)喷涂后的空调滤网放置在54℃、相对湿度>75%的恒温箱内烘烤14天(等同老化1年)得到检测样品,并于放置前、后分别测定消毒剂杀菌有效成分含量,如图4所示,每次检测样品为三批,每批样品重复测两次,取其平均值;试验结果表明,长效物表消毒剂的抗病毒活性率大于99%。
综上所述,本发明公开了一种长效自消杀物表消毒剂,其按重量百分比计,包括:酒精75%-85%-98%;粘结剂0.5%-1%-2%-5%;固体消杀材料0.5%-1%-5%-10%;助剂 0.1%-0.5%-1%。采用本发明的长效自消杀物表消毒剂可以对空调、空气净化器、风扇等物体表面进行有效消毒,即使酒精挥发后,被喷涂的区域依然具有自消杀的能力,自消杀能力的寿命不低于1年。
