Description

一种涂层网布及其涂层的涂覆工艺
技术领域
本发明涉及网布的涂层领域，尤其涉及一种涂层网布及其涂层的涂覆工艺。
背景技术
具有网孔的织物即网布，目前为提高网布的耐磨性常常在网布上涂覆耐磨涂层，而目前的涂层网布的手感较差，且不易于清洗，网布涂覆耐磨涂层后虽然耐磨性得到提高，但是涂层网布的耐磨涂层将网布的网孔封堵，使得涂层网布的透气性却明显降低。
鉴于此，本发明人针对上述问题进行深入研究，遂有本案产生。
发明内容
鉴于现有技术的不足，本发明的目的在于提供一种透气性好，涂层具有皮质感，手感好，易于清洁的涂层网布。
本发明的另一目的在于提供一种涂层网布的涂覆工艺。
为了实现上述目的，本发明采用如下技术方案：
一种涂层网布，包括具有网孔层的网布，所述网孔层上设有若干个网孔，所述网孔层上涂覆有耐磨材料层，所述耐磨材料层上具有若干个透气孔，各所述透气孔与各所述网孔一一对应，所述耐磨材料层的厚度为15C-30C，所述耐磨材料层的组份包括热熔粉、聚氨酯、硅PU以及环己酮，各组分的重量比如下：
Figure BDA0002502056090000011
所述耐磨材料层上还贴附有透气性良好的七彩镭射膜，所述七彩镭射膜上贴附有透气性良好的反光膜，所述七彩镭射膜和所述反光膜的厚度均为10C。
所述网布为三明治网布，所述三明治网布包括底部的针织底层、中部的中空纱线层和上部的具有提花网孔的网孔层。
一种如上所述的涂层网布的涂层的涂覆工艺，包括以下步骤：
步骤一：将组成所述耐磨材料层的材料混合成复合材料，所述耐磨材料层的组份包括热熔粉、聚氨酯、硅PU以及环己酮，各组分的重量份中，所述聚氨酯为100份，所述热熔粉为12-17份、所述硅PU为35-45份，所述环己酮为12-17份，混合后加热形成浆料，加热温度为80℃-120℃；
步骤二：将所述浆料涂覆至光膜上，所述浆料的厚度为15C-30C，将所述网布的所述网孔层对准所述光膜上涂覆有所述浆料的面，将所述网布覆盖在所述光膜上，使得所述网布与所述光膜相粘合，形成粗制涂层网布；
步骤三：使用平板平压步骤二中的所述粗制涂层网布，使得所述浆料与所述网孔层充分结合，所述平板对所述网布的压强为600Pa-1000Pa，平压时间为10s-20s；
步骤四：将步骤三中平压后的所述粗制涂层网布再使用滚轮滚压，滚轮的重量为50kg-120kg，滚动滚动速度为100m/h；
步骤五：将步骤四中滚压后的所述粗制涂层网布转移至流水线烘箱中热烘，使得所述网孔层与所述浆料进一步结合，并将所述浆料烘干，流水线烘箱的温度为80℃-130℃，热烘时间为2s-10s；
步骤六：将步骤五中热烘后的所述粗制涂层网布表面的所述光膜撕去，使得所述光膜上与网孔对应处的所述浆料留在光膜上，所述网孔层上形成具有若干个所述透气孔的所述耐磨材料层，各所述透气孔与各所述网孔一一对应，从而得到涂层网布。
将步骤六中得到的所述涂层网布放置入贴膜机中贴附七彩镭射膜，所述七彩镭射膜贴附在所述耐磨材料层上，所述涂层网布贴附所述七彩镭射后再次放置入所述贴膜机中贴附反光膜，所述反光膜贴附在所述七彩镭射膜上，所述反光膜以及所述七彩镭射膜均具有良好的透气性且厚度均为10C。
所述反光膜为PE反光膜，所述七彩镭射膜为PE七彩镭射膜。
所述光膜为硅油纸、PE光膜、PET离型膜或CCK离型膜。
采用本发明的技术方案后，涂层网布的耐磨材料层的组份包括热熔粉、聚氨酯、硅PU以及环己酮，制成的耐磨材料层具有皮质感，手感好，易于清洗，耐磨损；由于耐磨材料层具有若干个透气孔，且各透气孔与网孔层的各网孔一一对应，使得涂层网布保持了网布原有的良好透气性。
涂层网布采用本发明的涂覆工艺后，涂覆工艺简单快捷，耐磨材料层与网孔层的结合性好，各透气孔与各网孔一一对应，保留了网布的透气性良好的优点。

具体实施方式
下面结合附图和具体实施例对本发明做进一步的说明，需要说明的是本发明中C为本领域公知，1C等于0.01mm。
如图1所示的一种涂层网布，包括网布，网布为公知常见的三明治网布，三明治网布包括底部的针织底层11、中部的中空纱线层12和上部的具有提花网孔的网孔层13。网孔层13上的提花网孔具有若干个，网孔层上涂覆有耐磨材料层2。耐磨材料层2上具有若干个透气孔，耐磨材料层2上的各透气孔与网孔层13的提花网孔一一对应，使得三明治网布涂覆耐磨材料层2后保持了良好的透气性；耐磨材料涂层的厚度为15C-30C；耐磨材料层2的主要组份包括热熔粉、聚氨酯、硅PU以及环己酮，以聚氨酯的重量份为100份为例，热熔粉的重量份为16份，硅PU的重量份为40份，环己酮的重量份为16份，按如上所述组份组成的耐磨材料层2，不仅增加了三明治网布的耐磨性，还使得三明治网布具有皮革感，质感好，易于清洗。
由上可知，采用如上所述的技术方案后，耐磨材料层2具有皮质感，手感好，且易于清洗，耐磨性好；耐磨材料层2上的各透气孔与网孔层13的提花网孔一一对应，涂覆耐磨材料层2后的三明治网布保持了良好的透气性。
优选的，耐磨材料层2表面还贴附有透气性良好的PE七彩镭射膜3，PE七彩镭射膜3的表面贴附有PE反光膜4，PE七彩镭射膜3和PE反光膜4的厚度为10C。由于PE七彩镭射膜3和PE反光膜4的厚度较薄，且透气性良好，因此PE七彩镭射膜3和PE反光膜4增加了涂层网布的美感的同时保持了涂层网布的良好透气性。
一种涂层网布的涂覆工艺，本实施例中，网布为如上所述的三明治网布，网布的长度为1.4m，宽度为1m，所使用的设备包括混合搅拌机、加热筒以及涂层机，混合搅拌机、加热筒和涂层机均为公知常用的设备，涂层机包括流水作业的浆料涂覆工序段、平板压合工序段、滚轮滚压工序段以及流水线烘箱工序段，涂覆工艺包括以下步骤：
步骤一：将组成耐磨材料层2的各组分材料放入混合搅拌机中混合成复合材料，复合材料的主要组份包括热熔粉、聚氨酯、硅PU以及环己酮，以聚氨酯的重量份为100份为例，其余组分中，热熔粉的重量份为16份、硅PU的重量份为40份，环己酮的重量份为16份；混合后的复合材料加入加热筒中加热，加热温度为80℃-120℃，加热后形成浆料；
步骤二：将浆料输送至涂层机中，并在涂层机的涂覆工序段放入光膜，光膜采用公知常用的材料制成，本实施例中，光膜为PET离型膜，所使用的PET离型膜足够大，保证所使用的三明治网布能够放置入PET离型膜中不露出，光膜放置完毕后，使用涂层机将浆料涂覆在光膜上，浆料的厚度为20C，涂覆后将三明治网布覆盖在光膜上，网孔层13对准涂覆有浆料的面，使得三明治网布与光膜相粘合，形成粗制涂层网布；
步骤三：将步骤二中所得的粗制涂层网布输送至平板压合工序段，使用平板平压三明治网布，使得浆料与网孔层13充分结合，本实施例中，平板的压力参数为100kg，平板平压时间为15s；
步骤四：将步骤三中平压后的粗制涂层网布输送至滚轮滚压工序段，使用滚轮滚压三明治网布，滚轮的压力为110kg，滚动滚动速度为100m/h；
步骤五：将步骤四中滚压后的粗制涂层网布输送至流水线烘箱工序段中热烘，使得三明治网布与浆料进一步结合，浆料烘干，流水线烘箱的温度为90℃，流水线烘箱的长度为2m，三明治网布通过流水线烘箱的时间为8s；
步骤六：将步骤五中热烘后的粗制涂层网布取出并撕去PET离型膜，PET离型膜上与各网孔对应处的浆料残留在PET离型膜上，网孔层上形成具有若干个透气孔的耐磨材料层2，各透气孔与各网孔一一对应，从而得到涂层网布；
步骤七：将步骤六所得的涂层网布放入贴膜机中，在耐磨材料层2的表面贴附PE七彩镭射膜3，贴附PE七彩镭射后取出；再放入贴膜机中，在PE七彩镭射的表面贴附PE反光膜4，PE反光膜4以及PE七彩镭射膜3均具有良好的透气性且厚度均为10C。
由上可知，采用本实施例的涂覆工艺，三明治网布在涂层机中涂覆耐磨材料层2，整个涂覆过程流水作业，生产效率高；涂覆工艺简单快捷，耐磨材料层2与网孔层13的结合性好，各透气孔与各网孔一一对应，保留了网布的透气性良好的优点。
所述实施例和图式并非限定本发明专利的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明专利的专利范畴。
