摘要：【中文】本发明公开了一种不变形不透底抗开裂单面同步对纹装饰薄板的制作方法，包括如下步骤：基材锯边；基材和模板砂光；同步钢板安装；自动喷雾装置安装调试；同步对纹定位热压；背面雾化处理；定型养生；修边打托。本发明通过材料的选择和处理，定位热压、雾化处理、定型修边等工艺方法将装饰纸压贴在超薄高密度纤维板上，解决了超薄高密度纤维板高温短时单面压贴后变形的技术难题。获得的装饰薄板对纹精准度高，美观大方，装饰效果好，耐磨耐划，环保健康；本发明制作工艺简单，制得的产品抗开裂，无色差不透底，厚度薄重量轻且不变形，运输方便，还可以与胶合板、细木工板和实木齿接板等各种基材复贴形成高档装饰板材，应用前景广阔。 【EN】The invention discloses a method for manufacturing a deformation-free, bottom-impermeable and crack-resistant single-side synchronous grain-aligned decorative sheet, which comprises the following steps: sawing edges of the base material; sanding the base material and the template; installing a synchronous steel plate; installing and debugging the automatic spraying device; synchronously aligning grains, positioning and hot pressing; back atomization treatment; shaping and preserving health; trimming and supporting. The invention presses and attaches the decorative paper on the ultrathin high-density fiberboard through the technical methods of material selection and treatment, positioning hot pressing, atomization treatment, shaping and trimming and the like, thereby solving the technical problem of deformation of the ultrathin high-density fiberboard after high-temperature short-time single-side pressing and attaching. The obtained decorative sheet has high grain aligning precision, attractive and elegant appearance, good decorative effect, wear resistance, scratch resistance, environmental protection and health; the invention has simple manufacturing process, the manufactured product has the advantages of cracking resistance, no color difference, no transparent bottom, thin thickness, light weight, no deformation and convenient transportation, and can be re-pasted with various base materials such as plywood, a block board, a solid wood tooth joint board and the like to form a high-grade decorative plate, thereby having wide application prospect.
