Problems solved by technology

But the above-mentioned two-component beauty joint agent has no bactericidal and antibacterial effect
[0007] In addition, the existing water-based beautifying agent has good waterproof performance, but it is easy to evaporate after construction, resulting in serious collapse after curing, and bubbles and cavities appear, which affect the overall aesthetics
And the life span is only 2 to 5 years

Description

technical field [0001] The invention belongs to the technical field of beautifying agents, and in particular relates to an environment-friendly anti-mold and antibacterial beautifying agent. Background technique [0002] The World Health Organization survey shows that indoor biological pollution is gradually devouring people's health. When pets play in the house, the shed hair and parasitic mites will enter the ground crevices at the same time. In addition, the food debris scattered on the ground will also fall into the cracks of the ground during cleaning and become the ration of microorganisms. These indoor microorganisms will spread viruses and bacteria. At the same time, it cannot be ignored that after four or five months, the surface of the gap is easy to turn black and moldy, and the blackening of the brick gap will breed bacteria, produce peculiar smell, affect the environment, and endanger human health. risk. [0003] Therefore, in the decoration process, in order ...
