Preparation method of TPU floor with good dimensional stability
The invention relates to the technical field of floors, in particular to a preparation method of a TPU floor with good dimensional stability. The TPU floor sequentially comprises a TPU embryonic membrane, a carbon fiber screen cloth composite layer and a PVC bottom layer from top to bottom. The preparation method of the TPU floor includes the steps that 1, the TPU embryonic membrane is prepared; the carbon fiber screen cloth composite layer is prepared; and the PVC bottom layer is prepared; and 2, the obtained TPU embryonic membrane, the obtained carbon fiber screen cloth composite layer and the obtained PVC bottom layer are attached together in a hot pressing manner, and the TPU floor with good dimensional stability is prepared. The preparation method has the beneficial effects that colored paste of the obtained TPU floor comprises carboxyl butadiene-acrylonitrile rubber and chlorinated polyethylene, and the peel strength between carbon fiber screen cloth and the TPU embryonic membrane is improved. Diisocyanate and oligomer dihydric alcohol are added into the TPU embryonic membrane, the machinability of the TPU embryonic membrane is improved, the TPU embryonic membrane can be better attached to the carbon fiber screen cloth composite layer in a fused manner, and peeling is avoided.
本发明涉及地板技术领域，具体涉及一种尺寸稳定性好的TPU地板的制备方法，所述TPU地板从上到下依次包括：TPU胚膜、碳纤维网布复合层和PVC底层；所述TPU地板的制备方法包括：步骤1：制备TPU胚膜；制备碳纤维网布复合层；制备PVC底层；步骤2：将所得TPU胚膜、碳纤维网布复合层和PVC底层热压贴合在一起制成尺寸稳定性好的TPU地板。本本发明的有益效果在于：本发明所得TPU地板的有色糊剂包括羧基丁腈橡胶和氯化聚乙烯，提高碳纤维网布与TPU胚膜之间的剥离强度。所述TPU胚膜中添加二异氰酸酯、低聚物二元醇，使其加工性能得到改善，可以较好的与碳纤维网布复合层熔融贴合，不剥离。
