Preparation method of environment-friendly TPU stone-plastic floor
The invention discloses a preparation method of an environment-friendly TPU stone-plastic floor. The environment-friendly TPU stone-plastic floor is prepared by taking a TPU wear-resistant layer, a TPU color film and a TPU stone-plastic base material as structural materials through a direct hot pasting method. In the TPU stone-plastic base material, high-hardness TPU resin is adopted as a main body, and part of elastic TPU is added. The components of the floor do not contain any halogen or any plasticizer component, so that the odor and precipitation problems of a micromolecular plasticizer are avoided; the TPU floor is good in abrasion resistance, the abrasion resistance of the abrasion-resistant layer with the same thickness is three times that of a PVC floor, particularly, the floor adopts TPU resin with different hardness, a core structure adopts high-hardness TPU, the strength, rigidity, thermal expansion and other performance of the floor are effectively improved, a certain proportion of elastic TPU is added in an auxiliary mode, the toughness of a base material is improved, and the service life of the floor is prolonged. And the phenomena of breakage and cracking of the base material and the floor in the production process, corner damage of slotting and the like are reduced. The surface of the prepared floor is composed of the TPU transparent sheet and the color film, the elasticity of the TPU transparent sheet and the color film is better than that of PVC, the foot feeling is comfortable, a certain mute effect is achieved, and the deformation resistance of the surface of the floor is high.
本发明公开了一种环保TPU石塑地板的制备方法，以TPU耐磨层、TPU彩膜、TPU石塑基材为结构材料通过直接热贴法制备而成；TPU石塑基材中采用高硬度TPU树脂为主体，添加部分弹性TPU。地板成分中不含任何卤素，不含任何增塑剂成分，无需小分子增塑剂的气味和析出问题；且TPU地板耐磨性好，同厚度耐磨层耐磨性是PVC地板的3倍，尤其是地板采用不同硬度的TPU树脂，核心结构采用高硬度TPU，有效改善地板的强度、刚性以及热膨胀等性能，辅助添加一定比例的弹性TPU，增加基材的韧性，降低基材和地板在生产过程中的破损开裂以及开槽的坏角等现象。本发明制备的地板表面由TPU透明片、彩膜构成，该部分弹性较PVC好，脚感舒适，有一定的静音效果，地板表面抗变形能力高。
