Problems solved by technology

[0003] During the rainy season in coastal areas and the south, due to the high air humidity, smooth surfaces such as indoor walls tend to accumulate a large amount of moisture or even reach the level of running water. When the indoor ventilation is not good, it is easy to cause peculiar smell on the walls or even mildew, hair growth, discoloration, and pink. The body loosens and falls off, thus limiting the scope of use of diatom mud
Moreover, natural diatom mud cannot decompose harmful gases in the room, and does not have the functions of antibacterial, air purification, smoke absorption, air temperature and humidity adjustment, etc.
The diatom mud wall paint currently used in the market, when encountering the rainy weather in the south, because the air humidity is too high and lasts for a long time, it is easy to cause the diatom mud wall to have peculiar smell or even mildew, hair growth, discoloration, softening and loosening , falling off; due to low hardness, it is easy to soften and fall off, and it is easy to be damaged at the corner (external corner); it is difficult to attach to protrusions such as lines during the construction process

preparation example Construction

[0019] The embodiment of the present invention discloses a preparation method of diatom mud wall paint, comprising the following steps: adding diatomite, nanometer titanium dioxide and dicalcium silicate to the zinc nitrate solution, adjusting the pH value of the solution to 4-6, and React at 60-80°C, suction filter, dry, and grind to obtain a powder mixture; add dispersant, surfactant, defoamer, pigment and water to the powder mixture, and stir to obtain a diatom mud wall top coat.

[0020] The diatom mud wall paint prepared by the invention has multiple functions such as automatically adjusting air humidity, purifying air, absorbing and decomposing chemical substances that cause human allergies, eliminating peculiar smell, treating indoor formaldehyde gas, absorbing smoke, preventing mold and mites, and the like. It can gradually strengthen the hardness of wall paint by gradually absorbing moisture in the air.

[0021] In the present invention, the nano-titanium dioxide add...

Embodiment 1

[0038] Prepare a 0.2mol / L zinc nitrate solution in advance, add 300-500 mesh diatomite, nano-titanium dioxide and dicalcium silicate (dicalcium silicate: zinc nitrate solution = 30% weight ratio) under stirring conditions; adjust the solution The pH value is 5; the reaction is heated and stirred at 60-80°C for more than 1 hour, filtered with water, dried, and ground to obtain a powdery mixture of diatom mud wall paint. When using, add dispersant, defoamer, surfactant and a certain proportion of water to the above powdery mixture, stir well and smear it on the wall; water spray test for more than 2 hours; there is no softening feeling when touched by hands, and no feeling of softening when kicked. Deformed, no footprints.

[0039] The weight ratio of described nano titanium dioxide and zinc nitrate solution is 1:10; The weight ratio of described diatomite and zinc nitrate solution is 3:10; The dispersant, surfactant, defoamer and diatom mud wall The volume ratio of the top coa...

Embodiment 2

[0042] Prepare a 0.2mol / L zinc nitrate solution in advance, add 300-500 mesh diatomite, nano-titanium dioxide and dicalcium silicate (dicalcium silicate: zinc nitrate solution = 10% weight ratio) under stirring conditions; adjust the solution The pH value is 5; the reaction is heated and stirred at 60-80°C for more than 1 hour, filtered with water, dried, and ground to obtain a powdery mixture of diatom mud wall paint. When in use, add dispersant, defoamer, surfactant and a certain proportion of water to the above powder mixture, stir well and apply it on the wall; use a shower to sprinkle water, 0.5 kg per square meter, and there is no softening feeling when touched by hand. Kicking slightly deformed.

[0043] The weight ratio of described nano titanium dioxide and zinc nitrate solution is 1:10; The weight ratio of described diatomite and zinc nitrate solution is 3:10; The dispersant, surfactant, defoamer and diatom mud wall The volume ratio of the top coat is 3:0.5:3:100. ...

Abstract

The invention provides diatom ooze wall paint and a preparation method thereof; the preparation method comprises: adding diatom ooze, nano titania and dicalcium silicate into zinc nitrate solution, adjusting pH of the solution to 4-6, allowing reacting at 60-80 DEG C, performing suction filtering, drying, and grinding to obtain powdery mixture; adding a dispersant, a surfactant, a defoaming agent, a pigment and water into the powdery mixture, and stirring to obtain the diatom ooze wall paint. The hardness of the diatom ooze wall paint prepared by the preparation method can be increased gradually by gradual water absorption, and a wall can also be protected from mildews, hairiness, powder loosening and dropping, and other problems due to excessive air humidity.

Description

technical field [0001] The invention relates to the technical field of wall paint, in particular to a diatom mud wall paint and a preparation method thereof. Background technique [0002] Diatom mud wall paint is called "breathable environmental protection functional wall material", which has the characteristics of sound insulation and noise reduction, air absorption, fire resistance and durability. The main raw material of diatom mud wall paint is natural inorganic mineral diatom mud, which has a natural porous structure, can absorb moisture and gas in the air, and has a certain bonding and film-forming effect. [0003] During the rainy season in coastal areas and the south, due to the high air humidity, smooth surfaces such as indoor walls tend to accumulate a large amount of moisture or even reach the level of running water. When the indoor ventilation is not good, it is easy to cause peculiar smell on the walls or even mildew, hair growth, discoloration, and pink. The b...
