Self-cleaning antibacterial glazed ceramic tile and production technology thereof

Abstract

The invention discloses a self-cleaning antibacterial glazed ceramic tile. The self-cleaning antibacterial glazed ceramic tile comprises a ceramic tile embryo layer, an engobe layer, a patterning layer and an abrasion-proof layer, wherein the ceramic tile embryo layer is coated with the engobe layer, the patterning layer and the abrasion-proof layer from inside to outside in sequence, a nano ZnO antibacterial agent is added in basic materials of the engobe layer, the patterning layer and the abrasion-proof layer respectively, and three antibacterial layers are formed on the surface of the ceramic tile embryo layer. A production technology of the self-cleaning antibacterial glazed ceramic tile comprises the following steps that A, water is sprayed on the surface of a dry ceramic tile embryo; B, ball milling and pulping are conducted on ceramic engobe basic materials and the nano ZnO antibacterial agent, and the surface of the ceramic tile embryo is coated with the pulp; C, ball milling and pulping are conducted on ceramic glaze basic materials and the nano ZnO antibacterial agent, and the pulp is printed on the surface of the engobe layer; D, ball milling and pulping are conducted on abrasion-proof glaze basic materials and the nano ZnO antibacterial agent, and the surface of the patterning layer is coated with the pulp; E, the glazed ceramic tile is sent to a roller kiln to conduct firing. According to the self-cleaning antibacterial glazed ceramic tile and the production technology, the process is simple, the cost is low, practicability is high, the application range is wide, and the self-cleaning antibacterial glazed ceramic tile has an enduring and efficient sterilization effect and is abrasion-proof.

Description

technical field [0001] The invention relates to the field of architectural ceramic wall and floor tiles, in particular to a self-cleaning and antibacterial porcelain glazed tile and a manufacturing process thereof. Background technique [0002] Households, hotels, hospitals and other environments are prone to bacteria and molds due to humidity and darkness. These pathogenic bacteria affect people's health and even endanger their lives. With the development of society and the improvement of people's living standards, people's awareness of environmental protection is also increasing, especially in the purification of the home environment. Therefore, for the most common glazed tiles used in interior decoration, the surface is required to have antibacterial function, especially the anti-slip tiles used in wet kitchens and bathrooms, because the surface is mostly concave-convex, and the concave-convex corners are easier to clean. Breed and hide bacteria, but most of the ordinary...

Problems solved by technology

However, the fabric is complex and contains a lot of nano-antibacterial agents. In addition to the high cost, it will also affect the brick shape and the bending resistance of the brick. The transparent glaze protective layer on the surface can effectively reduce the wear of the nano-antibacterial layer, but it is also due to the protective layer. The coverage of the nano antibacterial layer leads to the weakening of the effect of the nano antibacterial layer
