Mites are small animals belonging to the class of the arthropoda arachnids, generally about 0.5 mm in size, and some species of mites, which are only 0.1 mm in size, live in the hair follicles of humans and the skin of animals. More than 50000 mites are found in the world, and modern medical research shows that the mites are closely related to human health. Some mites can suck blood to bite people, so that the mites can damage the skin of a human body and cause skin diseases such as red swelling, inflammation and the like. In addition, mites are widely distributed in dark corners, carpets, mattresses, pillows, sofas, air conditioners and the like in homes and offices, wherein dust mites are most widely distributed and most affected, and dead bodies, secretions and excretions of the mites are all allergen sources, so that people can have diseases such as allergic dermatitis, asthma, bronchitis, nephritis, allergic rhinitis and the like, and the human health is seriously harmed. The ceramic tile is one of the most widely used building materials in modern household building materials, and if the surface of the ceramic tile is subjected to functional treatment, the mite-preventing and mite-removing effect is obtained, and the living sanitary conditions of residents can be greatly improved.

The technical scheme adopted by the invention is as follows: the anti-mite and mite-killing ceramic tile is composed of a ceramic tile body and an anti-mite and mite-killing slow-release film layer, wherein the anti-mite and mite-killing slow-release film layer is formed by atomizing an anti-mite and mite-killing emulsion, spraying the atomized anti-mite and mite-killing emulsion on the ceramic tile body, drying and curing the atomized anti-mite and mite-killing emulsion, and the raw material components of the anti-mite and mite-killing emulsion comprise 5-15% of an anti-mite and mite-killing effective substance, 3-12% of a film forming agent, 2-5% of an emulsifying agent, 0.5-2% of an antifouling agent, 0.2-0.5% of a preservative and the balance of.

Specifically, the ceramic tile body has the characteristic of smooth surface, the adhesion force of the surface treatment liquid with the mite preventing and removing effect on the market to the surface of the ceramic tile body is poor, and a film layer with a slow release effect cannot be formed on the ceramic tile body. According to the invention, the emulsifier is introduced to fully emulsify the oil-soluble anti-mite and mite-killing effective substance, the preservative is added to greatly improve the stability of the emulsified anti-mite and mite-killing effective substance, and the anti-mite and mite-killing emulsion is prepared by the film-forming agent and the water, so that the anti-mite and mite-killing emulsion can form an anti-mite and mite-killing slow-release film layer with strong adhesive force on the surface of a smooth ceramic tile. In addition, the anti-fouling agent is also introduced into the anti-mite and mite-killing emulsion, and the characteristic that the anti-fouling agent can resist common stains and water invasion in life is utilized, so that the condition that the anti-mite and mite-killing effect of a film layer is reduced due to stain coverage is effectively avoided, the effect durability of the anti-mite and mite-killing slow-release film layer is further enhanced, and the anti-mite and mite-killing and anti-fouling and antibacterial effects of the finally prepared ceramic tile are more durable.

As a further improvement of the above embodiment, the anti-mite and anti-mite effective substance is at least one selected from the group consisting of limonene oxide, citral, cinnamaldehyde, eucalyptol, menthol, thymol, citronellal, geranyl acetate, benzyl benzoate, linalool, caryophyllene and nerol acetate.
