Problems solved by technology

[0003] Chinese patent CN101633812A "An Elastic Texture Paint and Its Preparation Method" is mainly used for exterior wall decoration projects of public buildings and residential buildings. The elastic emulsion used is a compound method of silicon acrylic or pure acrylic, and heavy calcium of different specifications is used at the same time. Because the strength of heavy calcium is not as good as that of quartz sand, and the elasticity of the coating is too good, when it is applied to a wall with external insulation, the elongation rate caused by the temperature difference with the external insulation benzene board is

Example Embodiment

[0026] Example 1:

[0027] Special flexible texture coating for external thermal insulation wall, it is composed of raw materials with the following weight ratios:

[0028]

[0029] The method for preparing the above-mentioned coating is as follows: step 1, water, antifungal agent, preservative, dispersant, wetting agent, defoaming agent, titanium dioxide and heavy calcium are mixed together according to the above-mentioned mass percentages and dispersed at high speed, and are used for subsequent use. ;

[0030] In step 2, the emulsion, the quartz sand and the defoamer are mixed together according to the above-mentioned mass percentages, and added to the mixed solution prepared in the above-mentioned step 1, and stirred at a medium speed;

[0031] Step 3, mix cellulose and water according to the above-mentioned mass percentage, stir for 10-20 minutes, and stir to make a cellulose mixture, for subsequent use;

[0032] In step 4, the mixture obtained in the above-mentioned ...

Example Embodiment

[0047] Embodiment 2:

[0048] The weight ratio of each raw material is:

[0049]

[0050] Others are basically the same as those in the first embodiment, and are not repeated here.

Example Embodiment

[0051] Embodiment three:

[0052]

[0053] Others are basically the same as those in the first embodiment, and are not repeated here.

[0054] The present invention provides a complete organic combination of external thermal insulation and art paint for buildings. When using, first add a cationic sealing primer to the external thermal insulation system, a primer of the same color for the external wall, two flexible texture coatings, and finally a water-based fluorocarbon finish wall paint. Since the PH of the general external thermal insulation plastering mortar in the northern region is 12, the cationic sealing primer can ensure excellent water resistance, alkali resistance and salt resistance, and avoid the blooming and efflorescence of the coating. Water-based fluorocarbon finish wall paint can greatly improve the stain resistance of the paint, so that the building will still look brand new after a few years. The role of the same-color primer on the exterior wall is to ...

Abstract

The invention discloses a special flexible texture coating for an external heat insulating wall. The coating is characterized by: 1) mixing water, an antimildew agent, a preservative, a dispersing agent, a wetting agent, a antifoaming agent, titanium pigment and calcium carbonate according to a mass ratio, followed by carrying out high speed dispersion to provide a spare use; 2) then mixing an emulsion, quartz sand and the antifoaming agent according to a mass ratio, followed by being added to the prepared mixed solution from the step 1), then carrying out medium-speed stirring; 3) mixing cellulose and the water according to a mass ratio, and carrying out stirring to prepare a mixed material of the cellulose to provide a spare use; 4) adding the mixture prepared through medium-speed stirring to the mixed material of the cellulose to carry out stirring, such that the mixed material of the cellulose can provide uniform thickening effect; 5) carrying out a color treatment for the finished product from the step 4). The coating provided by the present invention has characteristics of free of crack, high cohesional strength, effective prevention from coating deterioration, good water resistance, excellent penetration resistance, excellent flexibility. With the coating provided by the present invention, the fine cracks can be filled so as to prolong a service life of the external heat insulating wall and effectively protect buildings.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a special flexible texture coating for external thermal insulation walls and a preparation method thereof. Background technique [0002] STUCCO (plaster) originated in Europe and the United States. At the beginning, cement was used as a binder. In order to avoid cracking, emulsion was used instead, which achieved the unity of artistic decoration and protection, and was applied to the protection of interior and exterior walls. After the 1990s, it became popular in Europe and America. It has recently become popular in China, mainly the brands of several foreign multinational companies. [0003] Chinese patent CN101633812A "An Elastic Texture Paint and Its Preparation Method" is mainly used for exterior wall decoration projects of public buildings and residential buildings. The elastic emulsion used is a compound method of silicon acrylic or pure acrylic, and heavy c...
