Abstract

The invention discloses odorless environment-friendly dried diatom ooze powder and a preparation method thereof. The dried diatom ooze powder comprises the following components in parts by mass: 3-7 parts of odorless redispersible latex powder, 20-40 parts of diatomite, 1-6 parts of nanometer titania, 1-30 parts of titanium dioxide, 10-35 parts of ash-calcium, 10-30 parts of coarse whiting, 5-45 parts of quartz powder, 10-30 parts of kaolin, 0.3-1 part of hydroxy propyl methyl cellulose and 0.1-0.5 part of starch ether. The components are uniformly mixed to obtain the odorless environment-friendly dried diatom ooze powder. According to the odorless environment-friendly dried diatom ooze powder disclosed by the invention, the odorless redispersible latex powder is added to serve as a main adhesive substance and achieves a synergistic effect with the other components, so that the dried diatom ooze powder is odorless, has extremely low harmful substance content, and has high adhesive property, excellent low-temperature film-forming performance and the like.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to an odorless and environment-friendly dry powder diatom mud and a preparation method thereof. Background technique [0002] With the rapid development of society, people have higher and higher requirements for the environmental protection performance of decoration. Art paint, wallpaper, latex paint, etc. can meet the aesthetic requirements, but the pollution of indoor air is relatively serious, which will affect the body and mind of the human body. Health, so diatom mud came into being. [0003] Diatom mud (Diatom mud) is a kind of interior wall environmental protection decorative wall material with diatomite as the main raw material. Sterilization and deodorization functions. [0004] However, the current diatom mud has many problems, such as strong odor before and after construction, high formaldehyde content, poor bonding performance, and prone to p...
