一种耐刮油画布及其生产方法
技术领域
本发明涉及油画布领域，具体涉及一种耐刮油画布及其生产方法。
背景技术
现有的油画布包括基材和涂层，基材是以纤维素和蛋白质等天然高分子化合物为原料，经化学加工制成高分子浓缩液，然后经纺丝和后处理而制成纺织纤维，再编制成的基布；涂层是将天然石粉、PVC混合搅拌成的浆料于基布上涂布形成；使用时先将基布有涂层一面喷绘打画后摆放在需要的位置。然而该种传统油画布的耐刮性能难以满足要求。
发明内容
针对上述问题，本发明提供了一种耐刮油画布，其能解决现有的油画布耐刮性能难以满足要求的技术问题。
其技术方案是这样的，一种耐刮油画布，其包括依次设置的基材、吸墨内层、吸墨中层和吸墨表层，其特征在于:
所述吸墨内层包括按重量份计的以下原料，水性丙烯酸乳液35份，天然石粉18份；
所述吸墨中层包括按重量份计的以下原料，醋酸乙烯乳液30份，天然石粉16份，聚乙烯醇4份；
所述吸墨表层包括按重量份计的以下原料，水性丙烯酸乳液35份，天然石粉18份，聚乙烯醇6.5份、滑石粉12份、环氧改性硅油10份、聚酰胺2份。
进一步的，所述天然石粉的粒径为5μm~8μm，所述滑石粉粒径为3μm~5μm。
进一步的，所述基材为化纤编织布。
本发明还提供了上述耐刮油画布的生产方法，包括以下步骤：
S1、将所述吸墨内层的各原料按照配比混匀后升温至60℃搅拌5分钟，形成的浆料以35g/m2-50 g/m2的干胶克重均匀的涂布在基材上，形成吸墨内层，并进行烘干处理；
S2、将所述吸墨中层的各原料按照配比混匀后升温至68℃搅拌5分钟，形成的浆料以35g/m2-50 g/m2的干胶克重均匀的涂布在吸墨内层上，形成吸墨中层，并进行烘干处理；
S3、将所述吸墨表层的各原料按照配比混匀后升温至110℃搅拌3分钟，形成的浆料以35 g/m2-50 g/m2的干胶克重均匀的涂布在吸墨中层上，形成吸墨表层，并进行烘干处理，得到成品。
进一步的，步骤S1、S2和S3中，烘干处理的具体操作为，以25m/min-30m/min的速度通过温度为80℃-110℃的烘箱。
本发明的耐刮油画布，吸墨表层由水性丙烯酸乳液、天然石粉、聚乙烯醇、滑石粉、环氧改性硅油和聚酰胺的混合浆料制得，并且对各组分的配比进行了调配，进而获得耐刮吸墨表层；吸墨内侧由水性丙烯酸乳液和天然石粉的混合浆料制得，吸墨中层由醋酸乙烯乳液、天然石粉和聚乙烯醇的混合浆料制得，具有较佳的吸墨性能，确保喷绘效果。
附图说明
图1为本发明的结构示意图。
具体实施方式
如图1所示，一种耐刮油画布，其包括依次设置的基材1、吸墨内层2、吸墨中层3和吸墨表层4；
基材1为化纤编织布；
吸墨内层2包括按重量份计的以下原料，水性丙烯酸乳液35份，天然石粉18份；
吸墨中层3包括按重量份计的以下原料，醋酸乙烯乳液30份，天然石粉16份，聚乙烯醇4份；
吸墨表层4包括按重量份计的以下原料，水性丙烯酸乳液35份，天然石粉18份，聚乙烯醇6.5份、滑石粉12份、环氧改性硅油10份、聚酰胺2份；
天然石粉的粒径为5μm~8μm，滑石粉粒径为3μm~5μm。
本发明还提供了上述耐刮油画布的生产方法，包括以下步骤：
S1、将吸墨内层的各原料按照配比混匀后升温至60℃搅拌5分钟，形成的浆料以35 g/m2-50 g/m2的干胶克重均匀的涂布在基材上，形成吸墨内层，并以25m/min-30m/min的速度通过温度为80℃-110℃的烘箱进行烘干处理；
S2、将吸墨中层的各原料按照配比混匀后升温至68℃搅拌5分钟，形成的浆料以35 g/m2-50 g/m2的干胶克重均匀的涂布在吸墨内层上，形成吸墨中层，并以25m/min-30m/min的速度通过温度为80℃-110℃的烘箱进行烘干处理；
S3、将吸墨表层的各原料按照配比混匀后升温至110℃搅拌3分钟，形成的浆料以35 g/m2-50 g/m2的干胶克重均匀的涂布在吸墨中层上，形成吸墨表层，并以25m/min-30m/min的速度通过温度为80℃-110℃的烘箱进行烘干处理，得到成品。
其中，上述生产方法中，浆料涂布的干胶克重越大，涂层越厚，烘干时速度需要降低、温度升高；原料混合时，可根据情况添加5份~15份去离子水。
本发明生产的耐刮油画布，相较于市面传统喷绘油画布，不仅耐刮性能好，而且具有较佳的吸墨性能，确保喷绘效果。
