Background

With the increasing speed of urbanization, the urban surface is gradually covered by materials such as buildings and various concretes. The floor tile is a kind of ground decoration material, also called floor tile, and is made up by firing strong soil, and its specification is various, and its quality is strong, pressure-resisting and wear-resisting, and can resist moisture. Some of them are glazed, have decorative effect and are mostly used for the ground and floor of public buildings and civil buildings. The floor tiles have various colors and varieties and wide choice, can be divided into glazed tiles, full-bodied tiles, polished tiles, vitrified tiles and the like according to the materials, but have poor antiskid effect. According to statistics, the casualties caused by slip accidents in daily life are only second to car accidents, wherein children, old people, pregnant women and people with inconvenient actions are the most serious, so that ground slip prevention becomes a great problem of public safety. Although China has not yet made corresponding safety regulations to specify the anti-skid requirements of floor tiles, developed countries in Europe and America have made strict safety requirements, and floor tile products with anti-skid effects inevitably become the mainstream in the future along with the improvement of safety consciousness of people and the popularization of people-oriented ideas.

The anti-skid mechanism of the prior anti-skid floor tile mainly comprises the following two mechanisms, the first mechanism is to paint anti-skid agent on the surface of the finished floor tile, the anti-skid agent attached to the surface of the tile body is utilized to improve the friction coefficient, the surface of the tile body is made into a structure with macroscopic or microscopic concavo-convex unevenness, the mechanical interlocking effect generated by the structure and the sole under pressure is utilized to improve the friction coefficient, but the defects of the prior method are obvious, the method for painting anti-skid agent on the surface of the finished floor tile is practical, the anti-skid effect is ideal, but the painted anti-skid layer is gradually worn along with the prolonging of the service time, so that the anti-skid effect is lost, the anti-skid effect can be realized by manufacturing some macroscopic concavo-convex or lines on the surface of the tile body, but the decorative effect of the masonry; the second method adopts corrosive liquid to treat the surface of the finished brick, which can enhance the anti-skid effect but also destroy the beauty of the surface of the brick body, the technological process is complex, the treatment period is too long, the method is not suitable for the existing large-scale production technology, the main raw material of the prior anti-skid liquid product is oxalic acid, the method is extremely toxic, most importantly, the pollution to underground water is caused, only ground materials can be corroded when the anti-skid liquid is used, the anti-skid function can be realized, the anti-skid function has no permeation function, the anti-skid function is kept for a short time, generally for several months, but also the structure of the brick surface is damaged, so that the stain resistance of the floor tile surface is reduced, stains are easier to remain, and the floor tile is not easy to clean, but related products on the market and related patents in the prior art hardly have a formula which can improve the anti-skid coefficient of the surface of the floor tile on the premise of ensuring the cleaning power.
