Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of anti-slip preparations, and particularly relates to an environment-friendly anti-fouling and anti-slip preparation and a preparation method thereof. Background Art
[0002] Although traditional concrete floors are suitable for a large number of floor projects in terms of hardness and anti-slip performance, in modern construction projects and interior decoration projects, due to the ugly appearance of concrete, easy mildew, and poor appearance caused by poor construction process control, it has gradually been replaced by smooth building materials such as marble, artificial stone, and terrazzo. However, when these smooth stone surfaces encounter water, a uniform water film will form on their surfaces, resulting in a decrease in the friction coefficient between the stone surface and the feet, making people very prone to slipping and falling.
[0003] Traditional anti-slip processes include anti-slip coatings, anti-slip mats, and making the surfaces of anti-slip tiles serrated or uneven. However, the applicability of anti-slip mats is not wide and they cannot be used in large-scale construction projects; applying an anti-slip agent on the surface of finished floor tiles can increase the friction coefficient by using the anti-slip agent attached to the brick surface, but the applied anti-slip layer will gradually be worn with the extension of the use time and the anti-slip performance will also disappear; treating floor tiles with a corrosive liquid can make the brick surface into a structure with uneven ups and downs, and use this structure and the suction cup effect generated by the sole under pressure to increase the friction coefficient and prevent slipping and falling, but the anti-slip agents on the market generally have poor penetration, and the uneven structure on the brick surface will become smooth again due to friction. Therefore, it is particularly important to develop a safe anti-slip preparation that can effectively increase the anti-slip coefficient of floor tiles. Summary of the Invention
