Description
技术领域Technical field
本发明涉及一种挤压涂布头的改进，尤其是一种接触式涂布唇结构及其挤压涂布头。The invention relates to an improvement of an extrusion coating head, in particular to a contact coating lip structure and an extrusion coating head thereof.
背景技术Background technique
现有的湿料挤压涂布，如锂电池电极材料的涂布，分为非接触式涂布和接触式涂布两大类。所谓非接触式涂布是指涂布头悬在基材上方，浆料从涂布头的狭缝被挤压出来后，靠自由落体的方式落到基材上，非接触式涂布具有涂布精度高（涂布精度包括但不限于厚度，均匀性等指标）的优点，其缺点是非接触式涂布只能在有背辊的情况下才可能涂布，无背辊时是无法涂布的。Existing wet material extrusion coating, such as coating of lithium battery electrode materials, is divided into two categories: non-contact coating and contact coating. The so-called non-contact coating means that the coating head is suspended above the substrate, the slurry is squeezed out of the slit of the coating head, and then falls on the substrate by free falling. The non-contact coating has coating The advantage of high cloth accuracy (including but not limited to thickness, uniformity and other indicators). The disadvantage is that non-contact coating can only be applied with a back roller, and it cannot be applied without a back roller. of.
所谓接触式涂布（如图1所示）是指挤压涂布头的一侧涂布唇100的唇部较另一侧涂布唇（200）的唇部长，其具有长的唇部的涂布唇100与基材300相接触，浆料从涂布头的狭缝400被挤压出来后，顺着较长的涂布唇100的唇部110外侧面流到基材300上被带走，形成涂布层。接触式涂布头由于浆料从涂布头的狭缝被挤压出来后是顺着较长的唇部外侧面流到基材上的，一直以来，受较长的唇部外侧面的表面光洁度，以及涂布唇的材料等因素的影响，其涂布精度没有非接触式的涂布精度高。但是，它的优点是可以在无背辊的情况下实现涂布。The so-called contact coating (as shown in FIG. 1) refers to that the lip portion of the coating lip 100 on one side of the extrusion coating head is longer than the lip portion of the coating lip (200) on the other side. The coating lip 100 is in contact with the substrate 300. After the slurry is squeezed out from the slit 400 of the coating head, it flows along the outer surface of the lip 110 of the longer coating lip 100 to the substrate 300 and is taped. Walk to form a coating layer. Because the contact coating head is squeezed out from the slit of the coating head, it flows along the outer surface of the longer lip to the substrate. The coating accuracy is not as high as the non-contact coating accuracy due to factors such as the finish and the material of the coating lip. However, it has the advantage that it can be applied without a back-up roll.
所在，现状是要想涂布精度高，就要采用非接触式涂布方式与背辊配合使用；但是，有些情况下，如受空间的限制无法安装背辊时，只能牺牲质量选择接触式涂布。Where it is, the status quo is to use a non-contact coating method with the back roll to achieve high coating accuracy; however, in some cases, if the back roll cannot be installed due to space constraints, the quality can only be sacrificed for the contact Coated.
