Problems solved by technology

[0003] Traditional antibacterial ceramics use nano-silver as an antibacterial agent. However, since it is easily clustered after being added to ceramic raw materials, the antibacterial effect is not good. Therefore, it is necessary to propose an antibacterial ceramic with good antibacterial effect and its preparation method.

preparation example Construction

[0025] The embodiment of the present invention also provides a preparation method of nano antibacterial tiles, including:

[0026] (1) Preparation of ceramic raw material powder: wash the ceramic raw material, pre-sinter, dry, pulverize, and pass through a 100-200 mesh sieve to obtain the ceramic raw material powder;

[0027] (2) Preparation of antibacterial agent: take silane coupling agent and add to nano silica sol, wherein, nano silica is 40-50% of the total weight of nano silica sol, stir for 30-50min, then add nano silver and neodymium oxide, stirred for 30-50 minutes, then added nano-titanium dioxide and cerium oxide, and stirred for another 30-50 minutes to obtain an antibacterial agent;

[0028] (3) Preparation of antibacterial ceramics: Add the antibacterial agent prepared in step (2) to the ceramic raw material powder prepared in step (1), wherein the antibacterial agent is 1-5% of the total weight of the ceramic raw material, ball mill after heating in a water bath...

Abstract

A nanometer antibacterial tile is disclosed and comprises ceramic raw materials and an antibacterial agent. The weight of the antibacterial agent is 1-5% of the total weight of the ceramic raw materials. The antibacterial agent is prepared from, by weight, 20-30 parts of nanometer silica sol, 2-3 parts of nano-silver, 1-2 parts of nanometer titanium oxide, 17-22 parts of a silane coupling agent, 2-3 parts of neodymium oxide and 1-2 parts of cerium oxide. The antibacterial agent comprising the nanometer silica sol, the nano-silver, the nanometer titanium oxide, the silane coupling agent, the neodymium oxide and the cerium oxide is added, wherein a cluster phenomenon between the nano-silver and the nanometer titanium oxide is effectively reduced through adopting the hydrosol of the nanometer silica as a carrier and adopting the silane coupling agent as a medium, the neodymium oxide and the cerium oxide which are rare earth oxides are introduced to activate antibacterial functions of the nano-silver and the nanometer titanium oxide, and the antibacterial functions of the nano-silver and the nanometer titanium oxide are effectively combined to achieve an excellent sterilization effect.

Description

technical field [0001] The invention relates to the technical field of tile preparation, in particular to a nano antibacterial tile and a preparation method thereof. Background technique [0002] Antibacterial ceramics is a new type of functional material that protects the environment. It is the product of the combination of antibacterial technology and ceramic technology. It maintains the original function and decorative effect of ceramic products while increasing the functions of disinfection, sterilization and chemical explanation. Therefore, it is widely used Used in all walks of life. [0003] Traditional antibacterial ceramics use nano-silver as an antibacterial agent. However, since it is easily clustered after being added to ceramic raw materials, the antibacterial effect is not good. Therefore, it is necessary to propose an antibacterial ceramic with good antibacterial effect and its preparation method. . [0004] The invention provides a nano antibacterial tile a...
