Abstract
一种光触媒水泥木丝板生产方法，将刨切成的竹木丝与水泥及水混匀，压成竹木丝板，再用浸泡或喷涂的方法披覆SiO2溶凝胶，干燥成膜后再用TiO2光触媒纳米溶凝胶浸泡或喷涂带有SiO2保护膜的竹木丝板，干燥后即成。本板可广泛应用于教学楼、居室、会议厅、戏剧院、音乐厅、播音室等建筑物的装潢，具有轻质、高强度、隔音、隔热、杀菌、消毒、防霉、除臭、净化空气、自洁防污、与空气接触的表面积大、木丝不易裂化破坏等优点。
Description
技术领域
本发明涉及一种用无机胶粘剂、竹木丝、光触媒浸喷剂为主要原料的具有杀菌、消毒、分解有害污染物、隔音、隔热功能的人造板及其生产方法。
背景技术
纳米级TiO2光触媒以其长效的杀菌、抑菌、除霉、除臭、净化空气、自洁防污性能，尤其是对经装潢的人居室内的游离甲醛、游离苯酚的分解净化，解决了长期来人们渴望得到解决的问题，因此，近年倍受世人关注，应用领域不断拓宽，技术创新层出不穷。经检索查新，在竹、木板体上结合TiO2光触媒浸喷剂直接覆于板体表面，无法克服光触媒在光反应中对有机板材的快速裂化破坏，影响板材的使用寿命；二是作为浸喷光触媒的基材的板体多为平面体，与空气接触的表面积小，光触媒的效能发挥欠充分，如CN2574897Y公开的“光触媒热固性树脂装饰板”，便是一例。
发明内容
针对现有技术的上述不足，本发明的目的是提供一种用竹、木丝制作的，使板体与空气接触的表面积更大的，TiO2光触媒不直接与板体接触，从而降低裂化破坏，提高使用寿命的，且具有杀菌、消毒、防霉、除臭、净化空气、隔音、隔热性能的光触媒水泥木丝板及其生产方法。
本发明采用的技术方案是：光触媒水泥木丝板生产方法包括如下步骤：
(1)用溶胶凝胶法制成二氧化硅溶凝胶备用；
(2)市售TiO2光触媒纳米溶凝胶备用；
(3)竹木丝板的制作：切丝机从单板中切得木丝或用刨丝机从竹、木材中刨得竹木丝，或从竹段中劈得竹丝，用硅酸盐水泥或镁水泥等，按灰木丝为0.5-3∶1的比例，加水拌均匀后，控制压力0.01-1MPa压成木丝板，整形后备用；
(4)将木丝板浸或喷上SiO2溶凝胶，干燥成膜后再浸或喷上TiO2光触媒纳米凝胶，干燥后即成。
所述的光触媒水泥木丝板生产方法制成的板，是由竹丝或木丝、水泥、SiO2溶凝胶、TiO2光触媒纳米溶凝胶组成，众竹或木丝上下纵横交错、杂乱重叠，叠合成网状结构，竹木丝条或板体表面由里及外为SiO2溶凝胶保护膜层、TiO2光触媒纳米溶凝胶层。
本发明的有益效果是：用竹木丝压成的板材，呈网状结构，因而省木材、轻质、高强度、隔音、隔热，在光触媒与木丝之间夹有SiO2保护膜，降低了光触媒在光反应时对木丝的裂化破坏，不影响竹木丝的使用寿命，并具有长效的杀菌、消毒、防霉、除臭、净化空气、自洁防污性能，尤其是分解净化室内装潢造成的游离甲醛、游离苯酚的性能，解决了人们长期渴望解决的问题。
具体实施方式
本发明下面结合实施例作进一步详述：SiO2溶凝胶采用溶胶凝胶方法制备，这是同行业普通技术人员熟知的，不细述。TiO2光触媒纳米溶凝胶可向北京求流环保技术科技有限公司求购；木、竹丝板的制作需经下列工序：原竹原木的预处理、刨丝或制成单板切丝、水泥木丝及水的配比、混合搅拌、铺装成型、压制、养护调湿、整形即成木(竹)丝板。
将木竹丝板先在SiO2溶凝胶池中浸泡30S，沥干后晾干或烘干成膜，披覆在竹木丝条或竹木丝板的表面上，晾干或烘干成膜，再在TiO2光触媒纳米溶凝胶池浸泡30S，或在板表面喷涂TiO2光触媒纳米溶凝胶，干后即成。
本光触媒水泥木丝板可广泛应用于教室、居室、会议厅、剧院、医院、音乐厅、转播室、机舱、车厢等建筑物和交通工具的装潢。
木丝、竹丝长60-500mm、厚0.2-1.5mm、宽0.3-4.0mm。
本申请材料中的SiO2溶凝胶、TiO2溶凝胶以无色透明的优选，文中凡提到木丝的，都包括竹丝，反之亦然；因本竹、木丝板是与无机的水泥搅匀压制的，竹木丝外包覆有水泥层而有所遮挡，光触媒对竹木丝的裂化破坏相应较轻，也可不采用SiO2保护膜层，直接一次性浸喷在竹木丝上，但相对而言，这应属改劣方案。

(4)将木丝板浸或喷上SiO2溶凝胶，干燥成膜后再浸或喷上TiO2光触媒纳米溶凝胶，干燥后即成。
