Description

低VOCs释放的水性漆树脂膜饰面实木复合地板及其制备方法
技术领域
本发明涉及实木复合地板的生产加工技术领域，尤其涉及一种具有低VOCs释放的水性漆树脂膜饰面实木复合地板及其制备方法。
背景技术
木地板是一种常用的地面装饰材料，主要品种包括强化木地板、实木复合地板、实木地板、浸渍纸层压板饰面多层实木复合地板。随着国家房地产全装修交付政策的实施，实木复合地板销量始终处于增长的态势，然而，由于其表面使用的是珍贵阔叶树种，在可持续发展方面面临诸多瓶颈，例如：(1)世界上主要的木材供应国均出台了相应的森林保护法规，导致阔叶材的资源供应趋紧，价格上涨；(2)天然木皮存在死节、活节等缺陷，而且早晚材之间存在色差，批次间存在色差，给修色涂饰造成困难；(3)由于其材质本身的差异性，导致加工过程效率低、难以规避劳动密集型的加工方式。
而近年来兴起的以PP、PVC等树脂膜作为贴面材料的地板，则能很好的避免上述问题，产品本身零甲醛，环保性能卓越，抗拉伸、抗寒能力强，能适应极端气候而不开裂，受到了消费者的青睐。目前，已有树脂膜地板相关研究报告，如在申请号为CN201910276596.0的专利公开了一种PP膜贴面复合地板的制造方法，提出了自上而下的PP膜表层、无醛胶黏剂层以及多层基材层的制造方法；在申请号为CN201810876577.7的专利公开了一种双组份结构的实木复合地板，提出了面层为PVC地板，通过双组份的异氰酸酯粘合底层胶合板。树脂膜一般存在硬度差、耐划伤差、与木质基材难粘接等问题，直接通过双组份的异氰酸酯将PVC地板与基材粘合存在强度不够的问题。且生产、运输过程中树脂膜表面不可避免的会产生一些擦伤、刮痕等缺陷，若能在树脂膜表面涂覆一层漆膜，既能遮盖其缺陷、形成保护，又能进一步提升其装饰效果。
水性漆技术已经在木质家具领域得到推广应用，水性漆相对于溶剂型涂料而言，是以水为稀释剂，不含可挥发有机化合物，对环境污染小。由于水性漆固含量不高，水性漆在固化成膜前需要烘干设备进行干燥除水，否则将影响成膜后漆膜的性能，这就导致能耗增加、生产时间延长、生产成本增加。应用于树脂膜地板必须解决漆膜硬度低、耐磨性差等问题。因此，非常有必要开发一种专用于树脂膜贴面地板的高固含水性UV漆。
发明内容
为了解决上述的技术问题，克服现有技术中的不足，本发明提供一种低VOCs释放的水性漆树脂膜饰面实木复合地板及其制备方法，包括水性漆面层、树脂膜装饰层、多层基材层及背板，由上至下依次为水性漆面层、树脂膜装饰层、多层基材层及背板。该制备方法包括以下步骤：
一、制备水性UV面漆
所述水性UV面漆固体含量≥80％，由60～90份水性超支化聚氨酯丙烯酸酯树脂、2～4份水性光引发剂、2～4份醇醚类成膜助剂、0.2～2份增稠剂、0.05～0.5份流平剂、0.2～1.5份润湿消泡剂、2～20份去离子水组成。
二、制备树脂膜装饰层
对PVC、PP等树脂膜表面、背面进行等离子、电晕或EB电子溅射处理，即得树脂膜装饰层。
三、制备低VOCs释放的水性漆树脂膜饰面实木复合地板
1)在桉木单板表面涂布胶水，按实木复合地板用多层胶合板每层纵横交错组坯，经冷压、热压后制成多层基材层；
2)多层基材层经平衡后，下表面涂布胶水粘合背板，组坯后经冷压、热压后制成基板；
3)基板经养生、开片、砂光、开槽加工后，上表面涂布熔融状态下的PUR热熔胶，粘合步骤二制得的树脂膜装饰层，冷压后形成半成品树脂膜贴面的实木复合地板；
4)在半成品树脂膜表面涂布步骤一制得的水性UV面漆，直接进行UV固化，制得低VOCs释放的水性漆树脂膜饰面实木复合地板。
作为上述方案的进一步描述，所述步骤一中水性UV面漆的制备方法为：
在反应釜中加入60～90份水性超支化聚氨酯丙烯酸酯，以1500～2500r高速分散下，将2～4份水性光引发剂、2～4份醇醚类成膜助剂、0.2～2份增稠剂、0.05～0.5份流平剂、0.2～1.5份润湿消泡剂、2～20份去离子水，搅拌20～40min，至各组分分散均匀且无油缩。
作为优选，所述步骤一中水性超支化聚氨酯丙烯酸酯为高官能度的聚氨酯丙烯酸酯，包括博兴科技的B-912、B-910A2、B-919B，长兴化学的6195-100、6196-100等中的一种或多种。
作为优选，所述步骤一中水性光引发剂为自由基I型光引发剂1173，光引发剂的作用是引发超支化聚氨酯丙烯酸酯树脂交联，增加涂膜的交联密度，进而增加硬度。
作为优选，所述步骤一中醇醚类成膜助剂为乙二醇丁醚、丙二醇甲醚、丙二醇乙醚、二丙二甲醇单甲醚、二丙二醇单丁醚、二丙二醇正丁醚中的一种或多种。
作为优选，所述步骤一中增稠剂为聚氨酯增稠剂，目的是为了改善和增加其黏度。
作为优选，所述步骤一中流平剂为聚醚改性聚二甲基硅氧烷，目的是为了改善涂膜表面的平整度、提高涂膜的平滑性。
作为优选，所述步骤一中润湿消泡剂为改性蓖麻油，目的是为了降低体系的表面张力、有效提高涂料在各种低表面能塑料基材的润湿性能，同时有效消除气泡、防止涂膜缩孔。
作为优选，所述步骤二中树脂膜厚度为0.1～2mm，包括面层、印刷层和树脂膜底片组成的复合层，对其表面、背面进行等离子或EB电子溅射处理目的是增加其表面粗糙度和反应活性，有利于提高水性UV面漆涂饰漆膜在其表面的附着力。
作为优选，所述步骤三中基材层所用材料为桉木单板，厚度为1.0～3.0mm；背板所用材料为榉木，厚度为0.6～3mm。
作为上述方案的进一步描述，步骤三中所用胶水为无醛大豆胶，胶水涂布量为200～300g/m2，工艺条件冷压时间1h、单位压力7～11kg/cm2，热压温度125℃、(70+25)s/mm、单位压力7～11kg/cm2后制成。PUR热熔胶涂布量为150～250g/m2，工艺条件冷压时间1～5min、单位压力5～10kg/cm2、放置12～24h。
本发明的另一个目的在于提供一种高固含水性UV面漆，该水性漆通过以下制备方法获得：
在反应釜中加入60～90份水性超支化聚氨酯丙烯酸酯树脂，以1500～2500r高速分散下，将2～4份水性光引发剂、2～4份醇醚类成膜助剂、0.2～2份增稠剂、0.05～0.5份流平剂、0.2～1.5份润湿消泡剂、2～20份去离子水，搅拌20～40min，至各组分分散均匀且无油缩。
本发明的有益效果是：
1、本发明提供了一种专用于树脂膜贴面地板的高固含水性UV面漆，相对于油性漆，更加环保、低VOCs释放，不但提升了树脂膜贴面地板的装饰效果，而且生产工艺相对简单、不用进行红外烘干可直接UV固化，所制得的地板漆膜附着力、硬度、耐划伤、表面耐磨等性能优异。
2、本发明在树脂膜表面、背面预先进行等离子、电晕或EB电子溅射处理，在表面涂饰本发明提供的高固含水性UV面漆，解决了树脂膜表面性能差的问题；背面使用PUR热熔胶很好地解决了树脂膜与木材粘结不强的问题。

实施例2
对实施例1中的步骤三生产工艺均不变，改变部分如下：
一、水性UV面漆的制备
在反应釜中加入80Kg水性超支化聚氨酯丙烯酸酯树脂(长兴化学6196-100)，以2000r高速分散下，将3Kg 1173、3Kg二丙二醇正丁醚、1.5Kg聚氨酯增稠剂(罗门哈斯RM-12W)、0.13Kg聚醚改性聚二甲基硅氧烷、1.1Kg改性蓖麻油(森昌泰和科技H-854)、10Kg去离子水，搅拌30min，至各组分分散均匀且无油缩。
二、树脂膜装饰层的制备
对PP树脂膜表面、背面进行EB电子溅射处理，即得树脂膜装饰层。
对比例1
对实施例1中的步骤二、三生产工艺均不变，仅采用市售固体含量41.1％的无穷花水性漆替代水性UV面漆制备水性漆树脂膜贴面的实木复合地板。
对比例2
对实施例1中的步骤二、三生产工艺均不变，仅采用市售油性漆替代水性UV面漆制备树脂膜贴面的实木复合地板。
对比例3
对实施例1中的步骤一、三生产工艺均不变，省略步骤二生产工艺，制备低VOCs水性漆树脂膜贴无醛实木复合地板。
对比例4
对实施例1中的步骤一、二、三生产工艺不变，仅采用双组份的异氰酸酯替代PUR热熔胶制备水性漆树脂膜贴面的实木复合地板。
按照GB/T 17657-2013、HJ 571-2010中的检测方法，检测实施例与对比例获得的地板的理化性能，结果见下表1所示。
表1
Figure BDA0002774499960000051
从实施例1与对比例1、对比例2中的数据可看出，对比例1中采用市售低固含水性漆时，测得的漆膜硬度为3B、漆膜附着力为2级、表面耐磨不合格、TVOC为0.09mg/m3·h，对比例2中采用油性漆时，测得的漆膜硬度为H、漆膜附着力为1级、表面耐磨合格、TVOC为0.18mg/m3·h，而采用本发明提供的高固含水性UV面漆的实施例1，测得的漆膜硬度为H、漆膜附着力为0级、表面耐磨合格、TVOC为0.06mg/m3·h，检测结果明显优于对比例1、对比例2；从实施例1与对比例3中的数据可看出，当对树脂膜不进行等离子处理时，测得的漆膜附着力为1级、浸渍剥离不合格(树脂膜与基板粘结处开胶)、耐剥离力明显降低，而经过等离子处理的实施例1，由于增加了树脂膜表面粗糙度和反应活性，使得漆膜附着力提升至0级、浸渍剥离合格、耐剥离力显著增加；从实施例1与对比例4中的数据可看出，采用双组份的异氰酸酯替代PUR热熔胶制备树脂膜贴面的实木复合地板，测得的浸渍剥离不合格(树脂膜与基板粘结处开胶)、耐剥离力明显降低、TVOC为0.14mg/m3·h，而采用PUR热熔胶制备树脂膜贴面的实木复合地板，测得的浸渍剥离合格、耐剥离力显著增加、TVOC为0.06mg/m3·h。本发明制得的低VOCs水性漆树脂膜贴面的实木复合地板，有效解决了水性漆与树脂膜附着力差、树脂膜与木材粘结不强的问题，较普通实木复合地板，拥有低VOCs释放、无醛环保、表面性能和力学强度良好的特点。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
