Abstract

The invention discloses a water-based inorganic liquid diatom coating and a preparation method thereof. Based on 100% of the total weight of the water-based inorganic liquid diatom coating, it comprises: modified silane solution 40-42%, diatomite 12-% 15%, negative ion material 0.5%-1%, pigment and filler 21%-23%, nano-anatase titanium dioxide 0.3-0.5%, dispersant 0.3%-0.5%, thickener 0.2-0.4%, water balance. The water-based inorganic liquid diatom coating of the invention has both the smooth and smooth feel of latex paint and the functions of ordinary diatom mud to purify air, automatically adjust air temperature and humidity, absorb sound and reduce noise, keep heat and heat insulation, and do not release harmful VOCs; The breathing diatom coating can avoid the growth of mold and mildew when the wall is in a humid environment for a long time without adding additional anti-mold additives; it also has the function of removing indoor formaldehyde and releasing negative ions, and the hardness of the paint film Up to 3‑4H, the scrubbing resistance is increased to more than 100,000 times, and the service life is long.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a water-based inorganic liquid diatom coating and a preparation method thereof. Background technique

[0002] Diatom mud is a natural environmental protection wall decoration material, which is used to replace wallpaper and latex paint. The main raw material of diatom mud is diatom mineral that has been formed for hundreds of millions of years-diatomite. Diatom mud itself does not have any Pollution, pure natural, the surface of its particles has countless tiny pores, the porosity is over 90%, and the specific surface area is as high as 65m 2 / g. It is this outstanding molecular sieve structure that makes diatom mud coatings have multiple functions such as air purification, automatic adjustment of air temperature and humidity, sound absorption and noise reduction, heat preservation and heat insulation, etc., which are incomparable to traditional coatings such as latex paint and...

Examples

Embodiment 1～4

[0042] Embodiments 1 to 4 relate to a kind of water-based inorganic environment-friendly negative ion blackboard paint respectively. The blackboard paint is a single-layer blackboard paint, and the blackboard paint includes the components shown in Table 1 based on the total mass of blackboard paint raw materials 100%. ; Wherein, the modified silane solution is a film-forming substance, which is prepared after hydrolysis and polymerization under acidic conditions by using the sol-gel method. Based on the total weight of the modified silane solution 100%, the content of the modified silane solution The specific composition is shown in Table 2.

[0043] The preparation method of the water-based inorganic environmental protection anion blackboard paint of embodiment 1~4 comprises the steps:

[0044] S1. Preparation of modified silane solution: mix methyltrimethoxysilane, dimethyldimethoxysilane, and ethyl orthosilicate, adjust the pH value to 2-3 with formic acid, add deionized wa...
