Description

一种释香型抗菌抗病毒生态板及其制备方法 技术领域
本发明涉及人造板生产技术领域，特别是一种释香型抗菌抗病毒生态板及其制备方法。
背景技术
在生存需求得到充分满足的条件下，人民对健康绿色生活需求的呼声越来越高。室内环境是人类生存环境的重要组成部分，人的一生过半时间都在室内度过，因此，室内环境的舒适性、环保性与安全性与人类生存质量息息相关。
致病细菌及病毒会随空气流动进入室内，形成传染的风险。室内环境中大面积使用的家居产品则成为了细菌和病毒载体，因此，通过赋予室内家居产品抗菌抗病毒性能，建立安全、环保的抗菌抗病毒环境成为了现代家居产品发展的重要方向。同时，为提升室内环境舒适度，通过特定手段对家居产品赋香也成为了近年来家居产品研发的重要方向之一。目前，主流的抗菌或抗病毒家居产品多采用表面涂覆无机系助剂的方法的实现。此类方法具备良好的效果，但功能助剂使用量大，对环境敏感易变性，且易造成重金属污染。因此，用植物源助剂赋予家居产品抗菌抗病毒功能也成为了现阶段的研究开发热点。天然植物的根、茎、叶、花、果实、种子、木质部、树皮等生理部位的提取物具有多种活性成分，包括萜烯类、多酚类、黄酮类、脂肪酸、生物碱类等，具有广谱的抗病毒、抑菌杀菌功效，且部分提取物具有沁人心脾的香气，可用于室内增香。
生态板产品的功能赋予方法一直是业界研究热点，该产品与植物源功能助剂的复合主要通过将乳化或微胶囊包覆后的功能因子与浸渍用或胶合用树脂混合实现。然而，传统的天然植物提取物中释香成分易挥发，生态板生产过程中的高压、高温条件使得分布于板材结构表面的乳液或微胶囊壁材崩塌，导致释香因子瞬间挥发或游离，难以起到持久释香的效果。而具备抗菌杀毒作用的非挥发性成分与饰面纸或胶黏剂复合后多数被深埋于板材内部，难以有效迁移到板材表面发挥作用。
因此，本发明提出，以易挥发释香因子与难挥发抗菌抗病毒因子特性为依据，通过分步封装组合的手段使负载于装饰胶膜纸层中的功能因子适应生态板生产中的高温高压工艺过程，并实现香气的持久释放及高效抗菌抗病毒。
发明内容
本发明旨在解决植物源释香抗菌抗病毒因子与生态板生产工艺兼容性差的问题。为此，本发明提出了一种植物源释香因子与抗菌抗病毒功能因子分步封装在浸渍胶膜纸中的方法，显著提升了植物源功能因子对生态板生产工艺中的高温高压过程的适应性，减少了植物源功能因子的无效损失与过量使用，能实现生态板产品的持久抗病毒抑菌。
本发明的发明构思：本发明以植物源释香因子及抗菌抗病毒因子的挥发性和热稳定性差异为依据，将易挥发植物源抗菌因子用微胶囊包覆并填充于浸渍用纸骨架结构中，并以第一道氨基树脂实现第一级封装，随后利用第二道氨基树脂进行第二级封装，进而 保证植物源释香因子对生态板加工过程中的高温高压的适应性以及生态板使用过程中香气的缓释性。同时，仅在第二道氨基树脂中复合难挥发且具有一定热稳定性的植物源抗菌抗病毒因子，实现对空气中细菌与病毒的触杀。随后，将浸渍胶膜纸与环保基材及平衡层组装，进而制备出具备持久释香抗菌杀毒功能的环保生态板材。
