Description

一种抑菌环保涂料
技术领域
    本发明涉及一种环保涂料，尤其涉及一种抑菌环保涂料。
背景技术
由于传统的涂料对自然环境和人体健康产生严重的影响，环保涂料逐渐成为研究的热点方向。目前国内外学者主要集中在水性涂料、粉末涂料、高固体份涂料的研发上。水性涂料以水为溶剂，来源广，但是固化周期长，能耗大；粉末涂料100%固体份，不使用溶剂，但是粉尘易造成空气污染，甚至是爆炸；高固体份涂料固体份含量在65%-85%，有机溶剂含量低，操作要求高且复杂，而且存在涂料粘度的问题。使用抑菌涂料可以实现环境无污染，特别是针对室内环境。常用的天然抑菌剂主要是壳聚糖，但是耐久性较差；有机胺类抑菌剂效果好，耐久性好，但是对环境有害；银系抑菌剂等无机抑菌剂成本昂贵。
发明内容
本发明的目的就是为了解决上述问题，提供一种抑菌环保涂料，它具有抑菌环保、拉伸性能好等优点。
为了实现上述目的，本发明采用如下技术方案：
一种抑菌环保涂料，包括壳聚糖、阿拉伯胶、大豆分离蛋白、肉桂精油、黄原胶、槐豆胶和水等原料，以壳聚糖为主要原料，结合水性涂料、高固体份涂料以及粉尘涂料的优点，结合微胶囊技术，经载体制备、微胶囊制备、涂料制备三步骤完成。
本发明的有益效果：利用本发明制得的抑菌环保涂料附着性好，拉伸性能优良，原料均为天然提取物或产物，绿色环保；壳聚糖是生物活性大分子，具有高分子化合物的共性，能吸水、保水、成膜等，成膜后机械强度良好。通过与大豆分离蛋白、黄原胶、槐豆胶复配能形成无毒、高效且拉伸性能好的涂料载体；以阿拉伯胶作为微胶囊的壁材，将肉桂精油进行包覆，形成粒径为1-l0um的微胶囊，缓释肉桂精油的抑菌作用。
具体实施方式
