Problems solved by technology

[0003] Due to the above-mentioned advantages of diatom mud coating, it is widely used in the market at present. However, due to the characteristics of diatom mud itself, when the wall surface coated with diatom mud is contaminated with pollutants, it is difficult to clean the wall with conventional cleaning methods. If you wash it directly with a wet towel or clean water, it will directly damage the wall coated with diatom mud and cause losses.

[0020] 51.5‰ microsilica powder enhances the scrub resistance of diatom mud;

[0021] 52‰ of quartz powder, improve the actual construction of diatom mud;

[0022] 1.13‰ retarder, the above-mentioned retarder contains A group retarder and B group retarder, the above-mentioned group A retarder is 0.47‰ citric acid, B group retarder is 0.66‰ sodium gluconate; The value range of the above group A retarder is 0.39‰~0.49‰, and the value range of the above group B retarder is 0.59‰~0.67‰; the function of the above citric acid is to delay the initial setting and final setting. Infl...

Embodiment approach 2

[0030] Embodiment 2: This embodiment is basically the same as Embodiment 1. The difference is that 1.6‰~2.2‰ wood fiber is added to the original formula to further improve water retention and increase the workability of diatom mud. The specific formula is as follows:

[0031] 300‰ of sulphoaluminate cement;

[0032] 514‰ diatomite;

[0033] 49‰ silicon powder;

[0034] 50‰ of talcum powder;

[0035] 1.03‰ retarder, the above-mentioned retarder contains A group retarder and B group retarder, the above-mentioned group A retarder is 0.41‰ tartaric acid, and B group retarder is 0.62‰ sodium gluconate; among them, The value range of the above group A retarder is 0.39‰~0.49‰, and the value range of the above group B retarder is 0.59‰~0.67‰;

[0036] 2‰ wood fiber;

[0037] 8.6‰ of hydroxypropyl methylcellulose ether;

[0038] 30‰ of dispersible latex powder;

[0039] 15.87‰ magnesium aluminum silicate;

[0040] 29.5‰ negative ion release agent.

Embodiment approach 3

[0041] Embodiment 3: This embodiment is basically the same as Embodiment 1, the difference is that 2.8‰~4.1‰ of titanium dioxide is added to the original formula, which can degrade formaldehyde in diatom mud. The specific formula is as follows:

[0042] 317.5‰ of sulphoaluminate cement;

[0043] 499.5‰ diatomite;

[0044] 50.5‰ silicon powder;

[0045] 48.5‰ of kaolin;

[0046] 1.1‰ retarder, the above-mentioned retarder includes A group retarder and B group retarder, the above-mentioned group A retarder is 0.41‰ tartaric acid, and B group retarder is 0.62‰ sodium gluconate; among them, The value range of the above group A retarder is 0.39‰~0.49‰, and the value range of the above group B retarder is 0.59‰~0.67‰;

[0047] 6.6‰ of hydroxypropyl methylcellulose ether;

[0048] 28.5‰ of dispersible latex powder;

[0049] 15.8‰ of bentonite;

[0050] 3.5‰ titanium dioxide;

[0051] 28.5‰ negative ion release agent.

Abstract

The invention belongs to the technical field of coatings and particularly relates to scrubbing-resistant diatom mud. After being stained with pollutants, an existing diatom mud wall surface is difficult to be cleaned by virtue of a conventional cleaning method, the wall surface coated with diatom mud is directly damaged when being directly cleaned with wet towels or clean water, and the loss is caused. The scrubbing-resistant diatom mud is prepared by the steps of stirring 28%-33% of sulphate aluminium cement, 47.5%-53% of diatomite, 4.5%-5.5% of silica power, 4.8%-5.5% of a filling material,0.098%-0.116% of a retarder, 0.65%-0.93% of cellulose ether, 2.67%-3.31% of dispersible latex powder, 1.37%-1.72% of a lubricating agent and 2.83%-3.21% of an anion releasing agent in percentage by weight at a speed of 80r / min-100r / min for above 20 minutes. Except the functions of conventional diatom mud, the scrubbing-resistant diatom mud further has the functions of resisting saltpetering, shrinkage crack, scrubbing and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a scrub-resistant diatom mud. Background technique [0002] Diatom mud (English: Diatom mud) is an environmentally friendly decorative wall material for interior walls with diatomite as the main raw material. , Sterilization and deodorization and other functions. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, but also functional. It is a new generation of interior decoration materials that replace wallpaper and latex paint. [0003] Due to the above-mentioned advantages of diatom mud coating, it is widely used in the market at present. However, due to the characteristics of diatom mud itself, when the wall surface coated with diatom mud is contaminated with pollutants, it is difficult to clean the wall with conventional cleaning methods. If you wash it directly with a wet towel or clean water, it will directly damage the wall surfac...
