Description

一种全兼容喷墨打印阻燃复合网格布及其制备方法
技术领域
本发明涉及广告喷绘材料领域，特别涉及一种全兼容喷墨打印阻燃复合网格布及其制备方法。
背景技术
广告喷绘网格布是广告喷绘材料的主要品种，其在广告行业的应用非常广泛。网格布还有个特点，网格布和单孔透差不多都是利用光学原理材料上布满小孔，然后在布上打印画面后在亮处的一面可以看到画面，在暗处的一面可以透过小孔看到布后面的景色，一般适用于外表为透明玻璃的商场之类，使人在商场外面只能看到商场外墙上的画面，在商场内部可以透过玻璃和网格布看到外面的景色。
现有广告喷绘网格布均由网格布和衬垫基材组成，其中网格布是广告图像载体，衬垫基材是为喷绘过程顺利走纸而设置的，同时衬垫基材还需具备较好的吸收网格布孔洞漏墨的能力，它不是最终使用产品的一部分，喷绘完成后，衬垫基材将从网格布上剥离。作为广告图像载体的网格布是具备均匀孔洞的透光效果，用于高楼墙体，一方面，从外侧可以有完整的广告画面，具备很好的广告宣传效果；另一方面，在内侧仍然有较好的透风、采光效果，网格布透风的特点对建筑物有良好的保护作用，也不会影响室内采光的效果。由于广告喷绘网格布逐步用于制作建筑物防护网、户内壁画、户内标牌、商场橱窗广告、商场吊幔广告等，这对传统广告喷绘网格布的阻燃性能提出了新的要求。
早期的广告网格布采用无纺布作为衬垫基材，近年来广告喷绘网格布逐步改用PE膜、PET膜、PVC膜等作为衬垫基材，膜的厚度一般为50～90μm，在制造成本中，无论无纺布衬垫基材还是各类衬垫膜均占了较大的比重，而最终将被剥离、去废，从而造成了较大的资源浪费。同时，现有各类衬垫膜虽然可以用于低端的溶剂、弱溶剂等打印，可以较好的吸收网格布孔洞漏过的溶剂型墨水；但是，由于欧美国家较为注重推广环保的Latex(水性乳胶墨水)打印，各类衬垫膜却不能吸收Latex水性乳胶墨水，衬垫基材上墨水不干会造成上层网格布打印图像堆墨、发花，均匀度、清晰度、分辨率明显下降。
如专利CN115354503A和专利CN114908581A公开的技术，现有广告喷绘网格布的打印涂层仍然是使用PVC糊树脂、有机溶剂、增塑剂、热稳定剂等制成，其制造过程的环保问题堪忧。同时，PVC最为常用的增塑剂是邻苯二甲酸二辛酯(DOP)或邻苯二甲酸二己酯(DEHP)，在人体内会形成的邻苯二甲酸盐类，不但会对人体激素产生影响，影响儿童发育，干扰荷尔蒙分泌，更能直接损害肝脏、肾等，有致癌风险。PVC常用的碱式铅盐、金属皂类、有机锡热稳定剂中则含有超限量的铅、镉、汞、锡重金属。受限于PVC类产品的不环保性能，现有PVC类的广告喷绘网格布对欧美国家出口大幅受限。
PVC类的广告喷绘网格布另一问题是耐候性差、加入过多助剂，使用半年即出现老化，涂层发黄，打印图像变色；涂层发脆，打印图像剥落。现有技术的广告喷绘网格布在长期使用过程中表现出较多现有技术的不足，大大限制了该类产品的发展与推广。
因此，亟需一种新的技术方案解决以上至少一个技术问题。

在其中一些实施方式中，水性树脂乳液包括水性丙烯酸乳液、水性聚氨酯乳液、乙烯-乙酸乙烯乳液、水性聚酰胺树脂、乙烯丙烯酸酯共聚物乳液、水性松香树脂和水性萜烯酚醛树脂中的至少1种。
进一步的，水性树脂乳液为水性丙烯酸乳液和乙烯-乙酸乙烯乳液，水性丙烯酸乳液和乙烯-乙酸乙烯乳液的重量比为(20-35)：(15-20)，最佳的，所述水性丙烯酸乳液和乙烯-乙酸乙烯(VAE)乳液的重量比为30：20。
在其中一些实施方式中，所述水性丙烯酸乳液的最低成膜温度为10～45℃。
进一步的，所述水性丙烯酸乳液的最低成膜温度为20～35℃；作为最低成膜温度为20～35℃的水性丙烯酸乳液的实例，包括但不限于江阴国联科技有限公司的GH9758、GH9728、GH9745，四川祥泰化工有限公司的AQ28B、AQ48B，山东君武化工的JW309。
所述江阴国联GH9758的最低成膜温度为32℃，所述江阴国联GH9728的最低成膜温度为21℃，所述江阴国联GH9745的最低成膜温度为26℃，所述四川祥泰AQ28B的最低成膜温度为20℃，所述四川祥泰AQ48B的最低成膜温度为34℃，所述山东君武JW309的最低成膜温度为23℃。

所述川维600的乙烯含量为24～28％，所述川维707的乙烯含量为21～25％，所述川维716的乙烯含量为16～20％，所述川维718的乙烯含量为18～23％，所述台湾大连DA101的乙烯含量为16～22％，所述台湾大连DA102的乙烯含量为20～26％，所述塞拉尼斯CP149的乙烯含量为22～24％。
本申请人专注于喷墨打印涂层1的开发，曾发明了多种喷墨打印涂层1的制备方法，水性丙烯酸树脂由于具有优良的最低成膜性、耐候性、黏结性能和打印性能等优点而被广泛应用于胶黏剂、涂料、造纸和印刷等行业中。但是，水性丙烯酸乳液的固含量普遍较低，多为35～45％，会影响涂层的固含量。由于本发明复合网格布是通过打印涂层1和基布层2浸扎涂布工艺结合制成，平幅浸轧机由轧车、轧液槽和传动装置等主要部分组成，给予织物肯定的轧余率,并使之均匀地分布于织物中,也称为轧液机。其主要技术目的是使织物轧液均匀和保持肯定的轧余率。为了获得较高的打印涂层1克重，当轧余率一定时，则需要提高打印涂料的固含量。为此，本发明添加一定比例的乙烯-乙酸乙烯(VAE)乳液，VAE乳液的固含量普遍较高，为55～60％。经过配合使用上述重量比的水性丙烯酸乳液和乙烯-乙酸乙烯(VAE)乳液，得到的打印涂层1的固含量超过50％。
在其中一些实施方式中，阻燃剂包括三氧化二锑、十溴二苯乙烷、十溴联苯醚、磷酸三甲苯酯、亚磷酸三苯酯、氢氧化镁、氢氧化铝、多聚磷酸铵、三聚氰胺磷酸盐、三聚氰胺尿酸盐、三聚氰胺焦磷酸盐、三聚氰胺、三异三聚氰酸酯、硼酸锌、季戊四醇中的至少1种。
在一些优选的实施方式中，所述阻燃剂为多聚磷酸铵、三聚氰胺尿酸盐和季戊四醇。
在一些优选的实施方式中，所述多聚磷酸铵、三聚氰胺尿酸盐和季戊四醇重量比为(10-20)：(5-10)：(5-10)。
进一步优选，所述多聚磷酸铵、三聚氰胺尿酸盐和季戊四醇重量比为15：5：5。
本发明采用有机、无机复合型P-C-N膨胀阻燃体系，其中，P-C-N膨胀阻燃体系以多聚磷酸铵为脱水剂、季戊四醇为成碳剂、三聚氰胺尿酸盐为发泡剂。膨胀型阻燃剂由三个部分组成：成碳剂、脱水剂、发泡剂等组成的。膨胀型防火涂料的特点是当涂层受热达到一定温度后即膨胀到10～100倍以上，这样在被涂面与火源之间形成海绵状碳化层，阻止热量向底材传导，同时产生不燃性气体，使可燃性底材的燃烧速度和燃烧温度明显降低，从而起到能阻止燃烧的发生。通过阻燃剂对打印涂层1改性，复合网格布大大提高了使用的安全性。
在其中一些实施方式中，颜料包括钛白粉、超细硅酸铝、硫酸钡、氧化锌、立德粉、锑白、超细碳酸钙、高岭土和滑石中的至少1种。
进一步的，颜料为超细硅酸铝和钛白粉，超细硅酸铝和钛白粉重量比为(1-3)：(10-15)，所述超细硅酸铝和钛白粉的重量比为3：12。
基布层2透光性高，需要打印涂层1具备一定的遮光性，才能满足体现产品网孔均匀，上色均匀，画面饱和度好的要求。经过测试，所用打印涂层1透光率应该达到50％的要求。因此，在打印涂层1中添加一定比例的颜料，以提高打印涂层1的遮盖力，超细硅酸铝和钛白粉配合，其干膜遮盖力明显提高，白度大幅度提高。超细硅酸铝的网格结构使乳液体系稍增稠，具有很好的悬浮性，并防止固体成分的沉底及表面分水现象的出现。超细硅酸铝使乳胶漆膜有很好的耐擦洗性、耐候性、另外能缩短表干时间。
在其中一些实施方式中，抗氧稳定剂包括有机亚磷酸酯类抗氧剂、受阻酚类抗氧剂、胺类抗氧剂、硫代酯类抗氧剂中的至少1种，所述抗氧稳定剂为硫代酯类抗氧剂，包括但不限于临沂三丰化工的SONOX DLTDP、SONOX DSTDP。
在其中一些实施方式中，基布层2的材质包括涤纶、丙纶、锦纶、氨纶、腈纶、超高分子量聚乙烯纤维、玻璃纤维中的至少1种。
本发明发现，为了获得大面积的户外广告，需要对复合网格布的边缘重叠并进行热合拼接、打孔悬挂；但现有PVC网格布的基布层2多为涤纶布，涤纶布的弯曲疲劳性、抗拉伸性和抗切割性都较为一般。PVC网格布悬挂在户外，受打孔悬挂拉伸力和户外大风拉扯等的影响，在热合拼接和打孔孔洞处经常出现拉伸撕裂的问题，直接导致了大面积户外广告的破损、更换，造成了极大的麻烦。本发明发现选用超高分子量聚乙烯线强度比凯芙拉约高出40％，比碳纤维高两倍，是目前强度较高的纤维；线密度比水轻，抗切割，表面光滑，摩擦系数低，不易起毛，断裂伸长率3.5％，弯曲疲劳性好，耐腐蚀性极强，抗辐射性好，在紫外线下稳定。超高分子量聚乙烯纤维为本发明的复合网格布提供了优异的物理使用性能：(1)高比强度、高比模量、比强度是同等截面钢丝的十多倍、比模量仅次于特级碳纤维。(2)纤维密度低、密度是0.97g/cm3。(3)断裂伸长低、断裂强度大、具有吸收能量的能力，因而具有抗冲击性和抗切割性。(4)抗紫外线辐射、耐候性佳、耐化学腐蚀、耐磨性、有较长的挠曲寿命。
在其中一些实施方式中，衬垫基材3为铜版纸。
进一步的，所述铜版纸的单位面积克重为100g/㎡。
本发明发现，现有各类衬垫膜虽然可以用于低端的溶剂、弱溶剂等打印，可以较好的吸收网格布孔洞漏过的溶剂型墨水；但是，由于欧美国家较为注重推广环保的Latex(水性乳胶墨水)打印，各类衬垫膜却不能吸收Latex水性乳胶墨水，衬垫基材3上墨水不干会造成上层网格布打印图像堆墨、晕染、发花，均匀度、清晰度、分辨率明显下降。本发明选用吸墨水和热合性能俱佳的铜版纸，作为具备一定吸水(吸水性墨水)能力的表面施胶纸，可以有效地吸收网格布孔洞漏过的各类墨水(包括溶剂型墨水、弱溶剂型墨水、UV墨水、Latex墨水等)，避免在高速打印过程中的墨水不干而导致网格布打印图像堆墨、晕染、发花，保证网格布广告画面有很高的均匀度、清晰度、分辨率。同时，从成本方面考虑，100g/㎡铜版纸的成本为0.55元/㎡，而常见PVC膜、PET膜、PP合成纸等的成本都高于1元/㎡。网格布与衬垫基材3热压时，选用的铜版纸的一个表面施胶，加热后具有一定的软度，可以更好的与网格布结合，并且铜版纸有较好的挺度，可使得网格布喷绘打印过程走纸更为顺利，不易刮擦喷头。
在其中一些实施方式中，打印涂层1干基涂布量为60～120g/㎡，基布层2的克重为60～100g/㎡，进一步的，打印涂层1干基涂布量为80～100g/㎡，基布层2的克重为65～85g/㎡，复合网格布的总克重为160～180g/㎡
本发明发现，当选用上述克重时，能够保证良好的户外打印效果，严格的涂刮工艺流程使高分子材料很好地融合到超高强的超高分子量聚乙烯纤维的基布上，使材料的色彩表现趋于完美。同时，基布层2提供高强度的抗撕裂性，较为适用于制作建筑物防护网、户内壁画、户内标牌、商场橱窗广告、商场吊幔广告等。同时，本发明选用比重较低的涂层材料和基布层2材料，在同等厚度条件下，本发明的产品(整体比重仅为0.88-0.93)质量较PVC网格布(比重≥1.6)下降35-45％，考虑到市场上的户外广告的面积可以达到200㎡，如果使用本发明的网格布，其重量约为32～36kg，而PVC网格布则为46～52kg。本发明的网格布易施工、便操作，网状结构使得广告媒体的安装省去了背板等配套设施，大大降低了成本投入。
本发明还提供一种全兼容喷墨打印阻燃复合网格布的制备方法，包括以下步骤：
S1、打印涂料的配制：先将颜料、分散剂与水充分搅拌、研磨，制成固含量为不小于65％的分散浆料，将分散浆液与水性树脂乳液充分搅拌均匀，并加入流平剂、消泡剂、抗氧稳定剂，继续搅拌一段时间后用滤网过滤，静置消泡,制得固含量大于50％的打印涂料，备用；
S2、网格布浸扎涂布：基布层2经过放卷后，浸透打印涂料，然后经过定量网纹扎辊压出多余涂料，再通过恒温烘箱烘干水分，保证浸扎施胶干基克重为80～100g/㎡，得到网格布，打印涂料完全浸润基布层2，形成的打印涂层1与基布层2的附着牢度极佳；
S3、衬垫基材3热压：选用合适的衬垫基材3，使用网带复合机，并采用耐高温网带压着网格布和衬垫基材3，使网格布和衬垫基材3与烘筒充分接触受热，烘筒加热至100～120℃，使得网格布与衬垫基材3贴合平整，得到复合网格布。

对比例1
本对比例提供了一种全兼容喷墨打印阻燃复合网格布，具体实施方式同实施例1，不同点在于，衬垫材料选用PVC膜。
对比例1制得的全兼容喷墨打印阻燃复合网格布，PVC膜不能吸收Latex水性乳胶墨水，PVC膜上墨水不干会造成上层网格布打印图像堆墨、晕染、发花，均匀度、清晰度、分辨率明显下降。测试方法同实施例1。
对比例2
本对比例提供了一种全兼容喷墨打印阻燃复合网格布，具体实施方式同实施例1，不同点在于，基布层2为涤纶纤维网格布。
对比例2制得的全兼容喷墨打印阻燃复合网格布，由于基布层2为涤纶布，涤纶布的弯曲疲劳性、抗拉伸性和抗切割性都较为一般。网格布悬挂在户外，受打孔悬挂拉伸力和户外大风拉扯等的影响，在热合拼接和打孔孔洞处经常出现拉伸撕裂的问题，直接导致了大面积户外广告的破损、更换。
对比例3
本对比例提供了一种全兼容喷墨打印阻燃复合网格布，具体实施方式同实施例1，不同点在于，打印涂层1配方中不添加阻燃剂。
对比例3制得的全兼容喷墨打印网格布，由于没有阻燃改性，在用于制作建筑物防护网、户内壁画、户内标牌、商场橱窗广告、商场吊幔广告等领域时，不能满足安全性要求。
对比例4
本对比例提供了一种全兼容喷墨打印阻燃复合网格布，具体实施方式同实施例1，不同点在于，全兼容喷墨打印阻燃复合网格布的制备步骤中，涂层涂布工艺改为表面刮涂工艺。
对比例4制得的全兼容喷墨打印阻燃复合网格布，涂层与基布的附着牢度一般，多次弯折、拉伸，有涂层碎屑掉落问题。
上述实施例仅仅是为清楚地说明本发明所作的描述，而并非对实施方式的限定，对于所属领域的技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无需也无法对所有的实施方式予以穷举，而由此所引申出的显而易见的变化或变动仍处于本发明的保护范围之中。
