High-strength wear-resistant aluminum veneer and preparation method thereof
The invention relates to the technical field of decorative materials, in particular to a high-strength wear-resistant aluminum veneer and a preparation method thereof. In order to improve the strength and wear resistance of the aluminum veneer, the wear-resistant polyurethane emulsion with wear-resistant and corrosion-resistant functions is prepared, nano silicon dioxide is introduced into the wear-resistant polyurethane emulsion to serve as a reinforcing material, the nano silicon dioxide is modified, and fluorine and aldimine groups are introduced to the surface of the nano silicon dioxide, so that the wear resistance of the aluminum veneer is improved. The compatibility and the crosslinking property of the nano silicon dioxide and the polyurethane are improved; the wear resistance of a coating formed by drying the wear-resistant polyurethane emulsion is improved; therefore, direct contact between the aluminum single plate blank body and the outside is avoided, abrasion and corrosion of the aluminum single plate caused by the external environment are avoided, the use performance of the aluminum single plate is improved, and the durability of the coating outdoors is kept.
本发明涉及装饰材料技术领域，具体为一种高强度耐磨铝单板及其制备方法；本发明为了提升铝单板的强度与耐磨性能，制备了具有耐磨耐腐蚀功能的耐磨聚氨酯乳液，并在其中引入了纳米二氧化硅作为增强材料，并且本发明还对纳米二氧化硅做了改性处理，在其表面引入了氟元素与醛亚胺基团，改善了纳米二氧化硅与聚氨酯的相容性与交联性提升耐磨聚氨酯乳液干燥后构成的涂层的耐磨性能；从而避免了铝单板坯体直接与外界的接触，避免了外界环境对铝单板的磨损以及腐蚀，提高了铝单板的使用性能，保持涂层在户外的耐久性。
