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

[0037] Embodiment 1. A white plaster decorative wall material with self-cleaning function.

[0038]The white 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 whiskers 5; the second group: ① mica powder 6, ②, white cement 5, ③ sepiolite powder 3; the third group: ① titanium dioxide 3; the fourth group: ① quartz powder 25, ②Quartz sand 25; In addition, an independently packaged commercially available silicone waterproofing agent for building surfaces is provided, which is applied to the outer surface of the white plaster decorative wall material after construction, and the dosage of the silicone waterproofing agent is determined according to its instruction manual. Wherein, in the first group of raw materials, the redispersible latex powder is water-soluble polyv...

Embodiment 2

[0039] Embodiment 2, the preparation method of the white plaster decorative wall material with self-cleaning function.

[0040] The preparation method provided in this embodiment comprises the following steps:

[0041] ⑴. Measure the following raw materials: ①Redispersible latex powder, ②Cellulose ether, ③Defoamer, ④Lubricant, ⑤Whiskers as the first group of raw materials; add the first group of raw materials to the cone in sequence In the double-helix mixer, during the feeding and stirring process, each raw material is added to start the mixing and stirring operation; the double helix of the conical double-helix mixer includes autopropagation and revolution, and its autorotation power is 5.5kw, and the speed is 60r / min. Power 5.5kw, speed 7r / min;

[0042] ⑵. Measure the following raw materials: ① mica powder, ② white cement, ③ sepiolite powder as the second group of raw materials; add the second group of raw materials to the materials obtained in step ⑴ according to the orde...

Embodiment 3

[0047] Embodiment 3, construction method of scraping coating of white plaster decorative wall material.

[0048] 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;

[0049] 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 white stucco decorative wall material with a self-cleaning function. The preparation method comprises the following steps: firstly adding redispersible latex powder, cellulose ether, a defoaming agent, a lubricating agent and crystal whisker into a conical twin-screw mixer, mixing and stirring, then adding mica powder, white cement and sepiolite powder into the material obtained in the former step, and then adding titanium dioxide into the material obtained in the former step; then adding quartz powder and quartz sand into the material obtained in the former step, stirring and mixing to obtain the white stucco decorative wall material. A material formula adopted by the invention, and especially a grading uniformly-mixing preparation procedure adopted during preparation, have good beneficial effects: the stucco decorative wall material effectively overcomes the defects that the conventional artistic paint, texture paint, real-stone paint, latex paint and the like have low hardness of coating surfaces and the coating surfaces cannot be polished.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a white 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 interior ...
