Definitions

  • the invention relates to a green and environmentally friendly new material, and in particular to a synergistic antibacterial and mildew-proof agent and a preparation method thereof.
  • Metal ions such as silver, copper and zinc attach to the cell wall membrane. Their strong adsorption force allows them to penetrate the cell wall and enter the bacterial cells.
  • the metal ions destroy the proteins in the bacterial cells and change their helical structure (the -NH2 , -SH and -COOH groups on the proteins can react with most heavy metal ions).
  • the proteins lose their activity, making the bacterial cells unable to divide and regenerate (the active center of the protein-enzyme is mainly composed of amino, hydroxyl, sulfhydryl and carboxyl groups, so most enzymes can be inhibited by heavy metal ions), thereby killing the bacteria.
  • the antibacterial agent carriers mainly include porous ion exchange materials such as zeolite, montmorillonite, silica, zirconium phosphate, etc., which improve the heat resistance, dissolution, migration and other problems of inorganic metal ion antibacterial agents.
  • the main shortcomings are poor dispersibility in polymer systems such as plastics, rubber and textiles, slow antibacterial effect, and inability to eliminate viruses as quickly as organic antibacterial agents.
  • the inhibitory effect on spore fungi and plum fungi is weak.
  • the mechanism of action of quaternary ammonium salt fungicides is mainly that positively charged cations adsorb negatively charged bacteria and aggregate on the cell wall, producing a chamber barrier effect, resulting in bacterial growth inhibition and death; at the same time, its hydrophobic group interacts with the hydrophilic group of bacteria, changes the permeability of the membrane, and then lyses, destroys the cell structure, and causes cell dissolution and death. It has high efficiency, low toxicity, is not easily affected by pH changes, has long-lasting bactericidal activity, has a strong stripping effect on the mucus layer, has stable chemical properties, good dispersion and corrosion inhibition, and has the characteristics of algaecide and flocculation. It is widely used internationally.
  • ordinary quaternary ammonium salts have low chemical activity and basically exist in a free state when used. They are relatively toxic and irritating. When used as an antibacterial agent on textiles, they are dissolution-type, easy to wash off, and easy to enrich on the human body surface. Long-term use is prone to cause lesions.
  • the first technical purpose of the present invention is to provide a synergistic antibacterial and antifungal agent that can effectively solve the dissolution and thermal stability problems of quaternary ammonium antibacterial agents.
  • the second technical purpose of the present invention is to provide a method for preparing a synergistic antibacterial and antifungal agent.

  • the antibacterial and mildew-proof agent of the present invention effectively solves the dissolution and thermal stability problems of quaternary ammonium salt antibacterial agents and the dispersibility problems of inorganic antibacterial agents, and has a wider antibacterial spectrum than existing inorganic antibacterial agents and quaternary ammonium salt antibacterial agents.
  • the present invention effectively solves the thermal stability and dispersibility problems, mainly because zeolite has a complete crystal structure and is tightly combined with the loaded ions, thereby improving the original thermal stability. When dissolved in water, water molecules can surround the ions, so that the ions are no longer combined with the skeleton on the crystal, thereby improving the dispersibility.
  • a method for preparing a synergistic antibacterial and antifungal agent comprises the following preparation steps:
  • the surface of the carrier is modified by using an organic silicon quaternary ammonium salt containing an alkoxy group.
  • the alkoxy group reacts with the hydroxyl group on the surface of the carrier to form a Si-O bond, so that the quaternary ammonium salt is firmly bonded to the carrier.
  • the porous cationic ion exchange carrier containing surface hydroxyl groups is used to load silver, copper and zinc metal ions, specifically comprising: adding 200-30 parts by weight of silver nitrate or copper sulfate solution to 100 parts by weight of zeolite, dispersing at high speed, reacting at a temperature of 70-80° C., and reacting at normal pressure for 1.5-2.5 hours.
  • the use of a porous cationic ion exchange carrier containing surface hydroxyl groups to load silver, copper and zinc metal ions specifically includes: adding 250 parts by weight of silver nitrate or copper sulfate solution to 100 parts by weight of zeolite, reacting at a temperature of 75° C. and reacting at normal pressure for 2 hours.
  • the method of surface modification with alkoxy-containing organosilicon quaternary ammonium salt specifically comprises: adding 5-15 parts by weight of organic quaternary ammonium salt solution to 100 parts by weight of zeolite, dispersing at high speed, reacting at a temperature of 70-80° C., and reacting at normal pressure for 1.5-2.5 hours.

Description

一种协效抗菌防霉剂及其制备方法 技术领域
本发明涉及一种绿色环保新材,特别涉及一种协效抗菌防霉剂及其制备方法。
背景技术
银铜锌等金属离子附着在细胞壁膜上,强大的吸附力使其穿破细胞壁,进入细菌细胞内部,金属离子对细菌细胞内的蛋白质进行破坏,改变其螺旋结构(蛋白质上的-NH 2基,-SH基和-COOH基可与大部分的重金属离子反应),蛋白质丧失了活性,导致细菌细胞无法进行***再生的能力(蛋白质-酶的活性中心主要是由氨基、羟基、巯基和羧基组成的,因而大部分的酶都可以被重金属离子抑制),达到杀死细菌的效果。
银、铜、锌离子不稳定,容易溶出和迁移,造成健康和环境问题,并影响抗菌的持久性。目前市场上无机纳米抗菌剂主要采用载体加以改善,抗菌剂载体主要有沸石、蒙脱石、二氧化硅、磷酸锆等多孔离子交换材料,提高了无机金属离子抗菌剂的耐热、溶出、迁移等问题,目前存在的不足主要有在聚合物体系如塑料、橡胶及纺织上分散性较差,抑菌的迟效性,不能像有机抗菌剂那般迅速消灭病毒,对孢子菌、梅菌的抑制效果较弱。
季铵盐杀菌剂的作用机理主要是带正电荷的阳离子吸附带负电的细菌体并聚集在细胞壁上,产生室阻效应,导致细菌生长受抑而死亡;同时其疏水基与细菌的亲水基作用,改变膜的通透性,继而发生溶胞作用,破坏细胞结构,引起细胞的溶解和死亡。具有高效、低毒、不易受pH值变化的影响、持续时间长的杀菌活性,且对粘液层有较强的剥离作用、化学性能稳定、分散及缓蚀作用较好,还具有灭藻、絮凝等特点,在国际上使用广泛。但是,普通季铵盐化学活性较低,应用时基本以游离态存在,毒性相对较大,刺激性也强,将其作为抗菌剂应用在纺织品上是溶出型的,易洗脱,且易在人体表面富集,长期使用易产生病变。
发明内容
