Instead, due to the characteristics of their natural ingredients, they may add a natural beauty to tiles. Plant-based preservatives can also give tiles better air permeability, help evaporate moisture inside tiles, and prevent deformation and damage caused by moisture accumulation; finally, the application of plant-based preservatives can also enhance the sensory experience of tiles. Due to its natural origin, it may bring a gentler and more natural touch and smell to tiles, thereby improving the comfort and satisfaction of users. In short, the introduction of plant-based preservatives not only enhances the practical performance of tiles, but also improves the overall quality and market value of the product, bringing a richer and more positive use experience to tile producers and consumers.

[0161] In the present invention, through the use of imitation stone materials, the surface of the ceramic tile can present a texture and gloss similar to that of natural stone, thereby improving the aesthetics and decorative effect of the product and meeting the consumer's demand for high-end decorative materials. The surface of the imitation stone ceramic tile has been specially treated and has strong pollution resistance, is easy to clean and maintain, and reduces the maintenance cost in daily use. The materials and production technologies used in the preparation process may be more environmentally friendly and reduce the burden on the environment. At the same time, the durability of the ceramic tile also means a lower replacement frequency, thereby saving resources. Imitation stone ceramic tiles can be produced in a variety of colors and textures to meet different design styles and personalized needs, providing designers with more creative space. Ceramic tiles with stone texture usually have good thermal stability, are not easy to expand and contract due to temperature changes, and are suitable for indoor and outdoor laying under various climatic conditions.
