Embodiment 1

[0045] A dry powder coating with attapulgite minerals added, comprising the following raw material components in parts by weight:

[0046] 512 parts of heavy calcium, 100 parts of attapulgite, 350 parts of white Portland cement (or gray for cool color), 1 part of retarder, 35 parts of titanium dioxide, 2 parts of thickening and water-retaining agent.

[0047] The above-mentioned preparation method of the dry powder coating with attapulgite minerals includes the following steps:

[0048] 1) The traditional attapulgite raw ore can be used after drying, grinding and sieving. It can also be washed, flotation, impurity removal, air-dried or calcined to enhance activity, and after grinding to 350 mesh or more, then The purity of attapulgite, suspension and adsorption are greatly improved, and it has excellent and unique film-forming properties. Fine and smooth. If whiteness requirements are required, high whiteness attapulgite or activated clay can be used as raw material, which c...

Embodiment 2

[0054] A dry powder coating with attapulgite minerals added, comprising the following raw material components in parts by weight:

[0055] It is basically the same as the above-mentioned Example 1, except that the original mass fractions are not equal. In this example, modified raw material bentonite is added to increase the smoothness of construction. The quality of each component is respectively:

[0056] 250 parts of ordinary Portland cement, 416 parts of heavy calcium, 300 parts of attapulgite, 3 parts of thickening and water-retaining agent, 30 parts of bentonite, and 1 part of retarder.

[0057] The above-mentioned preparation method of the dry powder coating with attapulgite minerals includes the following steps:

[0058] 1) The traditional attapulgite raw ore can be used after drying, grinding and sieving. It can also be washed, flotation, impurity removal, air-dried or calcined to enhance activity, and after grinding to 350 mesh or more, then The purity of attapulgi...

Embodiment 3

[0064] A dry powder coating with attapulgite minerals added, comprising the following raw material components in parts by weight:

[0065] It is basically the same as the above-mentioned Example 1, except that the difference in mass fraction between the components increases the concave-convex content to increase the fineness of the coating and the functionality of adsorption and dehumidification. The components are respectively:

[0066] 400 parts of ordinary Portland cement, 400 parts of attapulgite, 3 parts of thickening and water-retaining agent, 120 parts of heavy calcium filler, and 30 parts of light calcium. 1 part of retarder, 46 parts of attapulgite.

[0067] The above-mentioned preparation method of the dry powder coating with attapulgite minerals includes the following steps:

[0068] 1) The traditional attapulgite raw ore can be used after drying, grinding and sieving. It can also be washed, flotation, impurity removal, air-dried or calcined to enhance activity, an...

Abstract

The invention discloses dry powder coating added with attapulgite mineral and a preparation method thereof. On the basis that the total weight of the dry powder coating is 1000 parts, the dry powder coating is prepared from the following raw material components in parts by weight: 150 to 400 parts of portland cement, 50 to 500 parts of attapulgite, 5 to 50 parts of soluble aluminium salt, 2 to 7 parts of thickening water-retaining agent, 1 to 3 parts of retarder; 0 to 30 parts of color paste, and 450 to 550 parts of filler. The dry powder coating added with the attapulgite mineral adopts the attapulgite as a new-style internal filler, and the attapulgite has better adsorption capacity, and unique dispersibility, plasticity and viscous force, is heat-resistant and low in shrinkage rate after drying, and has no flocculation and no precipitation during suspension.

Description

technical field [0001] The invention relates to a coating, which belongs to the technical field of interior decoration materials, in particular to a dry powder coating added with attapulgite minerals and a preparation method thereof. Background technique [0002] The general interior decoration is ordinary rolling lime milk, which is an ancient, cheap and healthy traditional paint. [0003] For modern decoration, a putty powder (heavy calcium and talcum powder) is generally blended with 107 or 108 construction glue, plastered, and then rolled with latex paint, which is convenient and fast. For wallpaper decoration materials, apply adhesive on the putty wall surface, and spread paper with gorgeous patterns such as patterns and pictures. Cloth decoration materials are the same as wallpaper, the latter is mainly made of nylon, hemp and other fabrics. Various diatomite ash-calcium powders are used as the main material. Diatom mud is the main body of environmental protection an...
