The formaldehyde removal instrument with the efficient ventilation structure comprises a box body, a formaldehyde detector is fixedly installed on one side of the box body, two sets of through grooves are symmetrically formed in the position, below the formaldehyde detector, of the box body, air inlet fans are fixedly installed in the two sets of through grooves, and the air inlet fans are fixedly installed in the air inlet fans. First dustproof nets are arranged on the sides, located on the two sets of air inlet fans, of the two sets of through grooves correspondingly, a partition plate is fixedly installed in the box body, the box body is divided into a filtering cavity and a reaction cavity through the partition plate, and two sets of filtering plates are arranged in the filtering cavity; formaldehyde-containing gas in the outside is extracted into the filtering cavity through the two sets of air inlet fans, the aldehyde-containing gas is filtered through the two sets of filtering plates, formaldehyde in the air is preliminarily eliminated, the aldehyde-containing gas enters the reaction cavity through the multiple sets of ventilation pipes and reacts with a formaldehyde removal solution, the formaldehyde in the air can be thoroughly eliminated, and the formaldehyde removal effect is good. And the aldehyde removal effect is good.

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.
