Description
技术领域
本发明属于日化抗菌消毒剂技术领域，涉及一种释香型长效物理抗菌剂的制备方法。
背景技术
皮革产品，不论猪皮、牛皮还是野生动物的皮毛，不但易长霉而且总有一股难闻的气味；比如新购汽车座椅上的毛皮，经常散发不愉快又，的气味；还有橡胶制品；塑料制品也常带有一些异味，令人不舒服。现在，很多人喜欢养狗， 养猫，养宠物，宠物身上总是携带各种病菌和难闻的腥味。这就需要一种既能抗菌杀菌，又能散发香味，掩盖臭味的抗菌剂。
发明内容
为了克服现有技术的上述缺点，本发明提供一种释香型长效物理抗菌剂的制备方法，它在催化剂作用下发生酯交换反应，生成相应的酯类硅烷季铵盐，存放于醇类溶剂如乙醇、异丙醇，丙二醇等溶剂中，在使用过程中，遇到水、水汽，就发生水解作用，释放出带香味的醇，同时能杀灭或抑制各种细菌、真菌甚至病毒孳生蔓延。
本发明解决其技术问题所采用的技术方案是：一种释香型长效物理抗菌剂，它由含甲氧基的硅烷季铵盐、带芳香味的醇类在催化剂作用下发生酯交换反应，生成相应的酯类硅烷季铵盐并存放于醇类溶剂如乙醇、异丙醇，丙二醇中即可制得。
所述含甲氧基的硅烷季铵盐包括有三甲氧基硅丙基—N—十八烷基二甲基氯化铵、甲基二甲氧基硅丙基—N—十八烷基二甲基氯化铵，也包括乙氧基硅烷季铵盐如三乙氧基硅丙基—N—十八烷基二甲基氯化铵，甲基二乙氧基硅丙基—N—十八烷基二甲基氯化铵，季铵基上的烷基可以1-20个碳的烷基或芳烷基。
所述带芳香味的醇类包括苯乙醇、香叶醇、香芋醇、香草醇及芳樟醇。
所述催化剂为能进行酯化反应的酸性催化剂包括有硫酸、磺酸及烷基苯磺酸。
一种释香型长效物理抗菌剂的制备方法，其制备步骤是：
向存放有醇类溶剂或烷烃类溶剂或是芳烃溶剂的烧瓶中加入含甲氧基的硅烷季铵盐及带芳香味的醇类在催化剂作用下进行酯交换反应，将烧瓶温度控制在50～150℃，反应时间2～10小时，反应完成的程度通过分析酯交换反应放出的甲醇或乙醇的量来确定，或是反应后分离出硅烷季铵盐，再进行水解，分析释放出的香料醇的量来确定。
所述醇类溶剂为异丙醇或丙二醇。
本发明的积极效果是：它在催化剂作用下发生酯交换反应，生成相应的酯类硅烷季铵盐，存放于醇类溶剂如乙醇、异丙醇，丙二醇等溶剂中，在使用过程中，遇到水、水汽，就发生水解作用，释放出带香味的醇，同时能杀灭或抑制各种细菌、真菌甚至病毒孳生蔓延，能够应用在各种皮质产品、橡胶制品及塑料制品。

应用实施例二：
用做空调过滤网防霉释香剂，应用合成实例2的硅烷季铵盐以无水乙醇为溶剂，配成2%的喷剂，喷于空调过滤网上，固化后成防霉释香过滤网，使过滤空气的微生物大为降低，且散发出令人愉快的玫瑰香味。
应用实施例三：
用合成实例2的硅烷季铵盐用乙醇配成2%的喷剂，喷于內衣內裤上，人体出汗使硅烷季铵盐水解，释放出香味，同时抑菌，使体表微生物无法滋生。
本发明在催化剂作用下发生酯交换反应，生成相应的酯类硅烷季铵盐，存放于醇类溶剂如乙醇、异丙醇，丙二醇等溶剂中，在使用过程中，遇到水、水汽，就发生水解作用，释放出带香味的醇，同时能杀灭或抑制各种细菌、真菌甚至病毒孳生蔓延，能够应用在各种皮质产品、橡胶制品及塑料制品。
Claims (6)
1.一种释香型长效物理抗菌剂，其特征是：它由含甲氧基的硅烷季铵盐、带芳香味的醇类在催化剂作用下发生酯交换反应，生成相应的酯类硅烷季铵盐并存放于醇类溶剂如乙醇、异丙醇，丙二醇中即可制得。
2.一种如权利要求1所述释香型长效物理抗菌剂的制备方法，其制备步骤是：
向存放有醇类溶剂或烷烃类溶剂或是芳烃溶剂的烧瓶中加入含甲氧基的硅烷季铵盐及带芳香味的醇类在催化剂作用下进行酯交换反应，将烧瓶温度控制在50～150℃，反应时间2～10小时，反应完成的程度通过分析酯交换反应放出的甲醇或乙醇的量来确定，或是反应后分离出硅烷季铵盐，再进行水解，分析释放出的香料醇的量来确定。
3.如权利要求1所述释香型长效物理抗菌剂，其特征是：所述含甲氧基的硅烷季铵盐包括有三甲氧基硅丙基—N—十八烷基二甲基氯化铵、甲基二甲氧基硅丙基—N—十八烷基二甲基氯化铵，也包括乙氧基硅烷季铵盐如三乙氧基硅丙基—N—十八烷基二甲基氯化铵，甲基二乙氧基硅丙基—N—十八烷基二甲基氯化铵，季铵基上的烷基可以1-20个碳的烷基或芳烷基。
4.如权利要求1所述释香型长效物理抗菌剂，其特征是：所述带芳香味的醇类包括苯乙醇、香叶醇、香芋醇、香草醇及芳樟醇。
5.如权利要求1所述释香型长效物理抗菌剂，其特征是：所述催化剂为能进行酯化反应的酸性催化剂包括有硫酸、磺酸及烷基苯磺酸。
6.如权利要求1所述释香型长效物理抗菌剂，其特征是所述醇类溶剂为异丙醇或丙二醇。
