The invention belongs to the technical field of indoor coatings, and relates to a plant interior wall paint capable of releasing negative oxygen ions and a preparation method thereof. The plant interior wall paint capable of releasing the negative oxygen ions comprises the following components in parts by weight: 15-25 parts of potato gum, 10-25 parts of sweet potato gum, 15-25 parts of kiwi fruit vine gum, 1-5 parts of peanut oil, 3-10 parts of milk, 2-6 parts of honey, 4-8 parts of nano titanium dioxide and 5-15 parts of negative oxygen ion powder. Wherein the potato gum and the sweet potato gum are respectively obtained by adding water into potatoes and sweet potatoes, mixing, cooking at high temperature and uniformly crushing; the negative oxygen ion powder is composite mineral powder capable of generating negative oxygen ions. The prepared plant interior wall paint can better release negative ions released by the negative oxygen ion powder. Compared with interior wall paint prepared from chemical raw materials, the interior wall paint prepared from the chemical raw materials has the same number of negative oxygen ions, and the negative oxygen ion powder and titanium dioxide added into the paint are less than 60% of the interior wall paint prepared from the chemical raw materials.

This invention relates to the field of coatings, specifically to a wear-resistant, formaldehyde-removing artistic coating and its preparation method. The coating, by weight, comprises: 45-55 parts of waterborne polyurethane-modified acrylic emulsion, 15-25 parts of silane-modified filler, 4-8 parts of supported formaldehyde-removing filler, 6-12 parts of pigment, 0.2-0.6 parts of dispersant, 0.1-0.4 parts of defoamer, 0.3-0.8 parts of thickener, 1-3 parts of film-forming aid, and 15-25 parts of deionized water. This invention achieves a balance between film hardness and toughness by using waterborne polyurethane-modified acrylic emulsion as the film-forming substance and combining it with silane-modified filler. The polyurethane segments provide excellent flexibility and resilience, the acrylic segments provide high hardness, and the silane-modified filler forms a strong chemical bond with the resin matrix through a silane coupling agent, improving the overall performance of the coating and extending its service life.
