Wear-resistant ceramic tile and preparation process thereof
The invention relates to the technical field of ceramic tiles, in particular to a wear-resistant ceramic tile and a preparation process thereof. The preparation process of the wear-resistant ceramic tile comprises the following steps: applying silica sol to a finished ceramic tile for at least two times; and baking the finished ceramic tile to which the silica sol is applied to obtain the wear-resistant ceramic tile. Silicate ester, silane, a catalyst and other raw materials are adopted, a hybrid SiO2 film is formed on the surface of the ceramic tile in a chemical self-assembly mode, redundant methyl groups are treated at the high temperature of 350-450 DEG C, meanwhile, SiO2 is slightly infiltrated to the surface of the ceramic tile through the high temperature, and the effect of stabilizing the wear-resisting grade of the tile surface is achieved. As the silica sol is applied to the surface of the ceramic tile at least twice, the formed hybrid Si-O-Si nano film layer does not influence the original color and texture of the ceramic tile, but can improve the permeability of the finished product tile, that is, compared with the original finished product tile, the obtained wear-resistant ceramic tile has the advantages that the glossiness and the light sensation are not changed, but the wear resistance is greatly improved.
本发明涉及瓷砖技术领域，尤其涉及一种耐磨瓷砖及其制备工艺。耐磨瓷砖的制备工艺，包括如下步骤：在成品瓷砖上施加至少两次硅溶胶；将施加有硅溶胶的所述成品瓷砖进行烘烤处理，得到所述耐磨瓷砖。采用硅酸酯、硅烷、催化剂等原料，通过化学自组装方式在瓷砖表面形成杂化SiO2膜，再通过350‑450℃的高温处理将多余的甲基基团，同时高温会使SiO2轻微的熔渗到瓷砖表面，达到稳定砖面耐磨等级的作用。由于至少在瓷砖的表面施加了2次硅溶胶，形成的杂化Si‑O‑Si纳米膜层并不会影响瓷砖原本的颜色及纹理，反而会提高成品砖的通透性，即，获得的耐磨瓷砖较于原始的成品砖光泽度和光感均不变，但耐磨性有大幅提升。
