Problems solved by technology

[0002] At present, the effects of beautifying agents and caulking agents are not ideal in terms of mildew prevention and environmental protection, because beautifying agents and caulking agents are used in the gaps of tiles, or edge sealing such as balcony toilets, such as bathrooms, living rooms, etc. Wait
These places are prone to water accumulation, or are often cleaned with a mop, and the humidity is relatively heavy. In addition, the air pollution is relatively heavy now, and the PM data soars, so it will mold and breed bacteria, which will bring a lot of trouble to people's lives.

Embodiment 1

[0021] Preparation of nano magnesium oxide modified chitosan antibacterial agent.

[0022] 1) Weigh MgCl 2 Dissolve in absolute ethanol, add PEG400 as dispersant. After mixing evenly, raise the temperature to 50-60°C, and slowly add a certain amount of ammonia-water-ethanol solution with a volume ratio of (1:1) dropwise under continuous magnetic stirring to form a white precipitate. After dripping, continue the heat preservation reaction for 1.5h, take it out, and let it stand at room temperature for aging. The precipitate was separated by filtration, and the filter cake was washed several times with water and ethanol respectively, and dried in vacuum at 60°C to obtain a white precursor. Finally, it was calcined at 500° C. for 1.5 h in an air atmosphere to obtain nano-magnesia powder.

[0023] 2) Add the nano-magnesia powder into absolute ethanol and stir evenly, ultrasonically disperse, the ultrasonic frequency is 40KHz, and the ultrasonic dispersion time is 15min, to form...

Abstract

The invention discloses a mold-proof anti-microbial tile joint mixture and a preparation method thereof. The method comprises the following steps: taking easily acquired and low-cost nanometer magnesium oxide and chitosan as raw materials; performing chemical preparation, modifying treatment, water-bath heating compound, ice water cooling, centrifugal separation and vacuum freeze drying, thereby acquiring a nanometer magnesium oxide modified chitosan compound antibacterial agent; using the nanometer magnesium oxide modified chitosan compound antibacterial agent for preparing a tile joint mixture. The tile joint mixture prepared according to the invention has the advantages of low cost and good sterilizing effect. The color of the nanometer magnesium oxide modified chitosan is light when the nanometer magnesium oxide modified chitosan is applied to the joint mixture, so that the color of the joint mixture is not influenced.

Description

technical field [0001] The invention relates to the technical field of tile grouts, in particular to a mildew-proof and antibacterial tile grout and a preparation method thereof. Background technique [0002] At present, the effects of beautifying agents and caulking agents are not ideal in terms of mildew prevention and environmental protection, because beautifying agents and caulking agents are used in the gaps of tiles, or edge sealing such as balcony toilets, such as bathrooms, living rooms, etc. Wait. These places are prone to water accumulation, or are often cleaned with a mop, and the humidity is relatively heavy. In addition, the air pollution is relatively heavy now, and the PM data soars, so mold and bacteria will grow, which will bring a lot of trouble to people's lives. [0003] There are many types of antibacterial agents, and the classification methods are also different. Antibacterial materials can be divided into inorganic, organic and biological antibacter...
