Problems solved by technology

[0002] At present, the existing architectural decorative coating technologies, including art coatings, texture coatings, real stone paints, and latex paints, all have the defects of low hardness on the coating surface and the coating surface cannot be polished; especially when it is necessary to make stone-like pattern textures Or when the texture is obvious, because the surface of the coating is not smooth, it is easy to attach dust and dirt, so that the surface of urban buildings will obviously appear pieces of stains after two or three years, seriously affecting the appearance of the city.

Embodiment 1

[0029] Embodiment 1. A decorative wall material of colored plaster with self-cleaning function.

[0030] The colored plaster decorative wall material with self-cleaning function provided in this embodiment contains the following four groups of raw materials in parts by weight: the first group: ① redispersible latex powder 8, ② cellulose ether 0.8, ③ defoamer 0.8 , ④ Lubricant 0.5, ⑤ Whisker 5; Group 2: ① Mica powder 6, ② White cement 5, ③ Sepiolite powder 3; Group 3: ① Titanium dioxide 3, ② Inorganic powder pigment, the dosage is based on the product The color requirements are determined; the fourth group: ①Quartz powder 25, ②Natural colored sand 25; In addition, an independently packaged commercially available silicone waterproofing agent for the building surface is provided, after the construction of the colored plaster decorative wall material with self-cleaning function Coated to its outer surface, the amount of silicone water repellent is determined according to its instr...

Embodiment 2

[0032] Embodiment 2, the preparation method of the colored plaster decorative wall material with self-cleaning function.

[0033] The preparation method provided in this embodiment comprises the following steps:

[0034]A. Prepare the color premix. In the first step, take titanium dioxide and add it to the high-speed centrifugal disperser for centrifugal dispersion. In the second step, add the inorganic powder pigment to the high-speed centrifugal disperser in the first step to disperse and mix well. The third step Take the same amount of titanium dioxide as the first step and add it to the high-speed centrifugal disperser in the second step to disperse and mix evenly, discharge and set aside; each step of operation is started and stirred for 3-5 minutes, and the speed of the dispersion shaft is 800r / min;

[0035] B. Handling of the first group of raw materials: Measure ①redispersible latex powder, ②cellulose ether, ③defoamer, ④lubricant, and ⑤whiskers as the first group of ra...

Embodiment 3

[0039] Embodiment 3, construction method of color plaster decorative wall material scraping coating.

[0040] Beating, this process is to complete the water fusion process of powder materials, with the ratio of powder: water = 1:0.6--1.0, first add 90% of the water into the beating container, and then add all the powder materials; use a portable Electric mixer, stirring for 5-8 minutes, standing still for 15-20 minutes, to complete the hydration and fusion process of the slurry, and adjust the performance of the slurry with 10% of the remaining water according to the actual situation on site;

[0041] Scrape the first coat of self-cleaning functional plaster decorative wall material slurry. When scraping, you can follow the general mortar scraping coating method. You can use metal spatulas, wooden spatulas, or plastic spatulas. The best solution is to use Metal spatula; the first pass of scraping is sufficient to achieve a smooth coating surface, with a thickness of 1-3mm;

Abstract

The invention discloses a preparation method of a colored plaster decorative wall material with a self-cleaning function. Firstly, redispersible latex powder, cellulose ether, an antifoaming agent, a lubricant and whiskers are added to a conical twin-screw mixer for mixing, then mica powder, white cement and sepiolite powder are added to the material obtained in the last step, and a pigment premix is added to the material obtained in the last step; quartz powder and natural colored sand are added to the material obtained in the last step, the material is mixed, and the wall material is prepared. A material formula is adopted, a classified even mixing preparation procedure is adopted particularly during preparation, and a good beneficial effect is realized. The plaster decorative wall material effectively overcomes the defects that the coating surface hardness of existing art paint, textured paint, stone-like paint, latex paint and the like is low and coating surfaces cannot be polished.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a colored plaster decorative wall material with self-cleaning function used on building exterior walls. Background technique [0002] At present, the existing architectural decorative coating technologies, including art coatings, texture coatings, real stone paints, and latex paints, all have the defects of low hardness on the coating surface and the coating surface cannot be polished; especially when it is necessary to make stone-like pattern textures Or when the effect of texture is obvious, because the surface of the coating is not smooth, it is easy to attach dust and dirt, which makes the surface of urban buildings obvious after two or three years. Stains will seriously affect the appearance of the city. Dust and dirt adhere to the decorative coating for a long time, and harmful substances such as carbon monoxide and sulfur dioxide penetrate into the interio...
