preparation example 1

[0048] The water-based polyurethane environmental protection primer is prepared from the following raw materials by mass percentage: 25% water-based polyurethane, 2.0% Degussa non-ionic wetting and dispersing agent BREAK-THRU DA 646, 40% deionized water, 1.5% % of BASF 2190 defoamer, 2.5% of Digao substrate wetting agent WET KL245, 3.0% of alcohol ester Twelve, 1.5% of VANTEX-T, 4.5% of polyacrylonitrile-based carbon fiber, 20% of environmentally friendly fillers .

[0049] The environmental protection filler is composed of diatomite, 5% of light calcium carbonate, 6% of titanium dioxide, 2.8% of active manganese powder, and 0.2% of zinc oxide whiskers, which account for 6% of the total mass of the water-based polyurethane environmental protection primer.

[0050] The preparation method of water-based polyurethane environmental protection primer comprises the following steps:

[0051] Step S1, 6.0kg of diatomaceous earth, 5kg of light calcium carbonate, 6kg of titanium dioxid...

preparation example 2

[0055] The difference between Preparation Example 2 and Preparation Example 1 is that the water-based polyurethane environmental protection primer is prepared from the following raw materials by mass percentage: 25% water-based polyurethane, 2.0% Degussa nonionic wetting and dispersing agent BREAK-THRU DA 646, 25% deionized water, 1.5% BASF 2190 defoamer, 2.5% Digao substrate wetting agent WET KL245, 3.0% Digao substrate wetting agent WET KL245, 1.5% VANTEX-T, 4.5% polyacrylonitrile-based carbon fiber, 35% environmentally friendly filler. The environmental protection filler is composed of diatomite, 8.75% light calcium carbonate, 10.5% titanium dioxide, 4.9% active manganese powder, and 0.35% zinc oxide whiskers, which account for 10.5% of the total mass of the water-based polyurethane environmental protection primer.

preparation example 3

[0057] The difference between Preparation Example 3 and Preparation Example 1 is that the waterborne polyurethane environmental protection primer is prepared from the following raw materials by mass percentage: 25% water-based polyurethane, 2.0% Degussa nonionic wetting and dispersing agent BREAK-THRU DA 646, 30% deionized water, 1.5% BASF 2190 defoamer, 2.5% Digao substrate wetting agent WET KL245, 3.0% alcohol ester Twelve, 1.5% VANTEX-T, 4.5% Polyacrylonitrile-based carbon fiber, 30% environmentally friendly filler. The environmental protection filler is composed of diatomite, 7.5% light calcium carbonate, 9% titanium dioxide, 4.2% active manganese powder, and 0.3% zinc oxide whiskers, which account for 9% of the total mass of the water-based polyurethane environmental protection primer.

Abstract

The application relates to the technical field of wall decoration, in particular to a green and environment-friendly exterior wall decoration method. A green and environment-friendly exterior wall decoration method, comprising the following steps: Step 1, filling the depressions on the wall with gypsum, polishing until the wall is smooth, scraping and coating methyl vinyl silicone rubber on the wall, and spraying rubber cross-linking after it is cured Step 2, scrape the water-based polyurethane environmental protection primer on the wall, wait for it to solidify into a gel state, spray polyurethane crosslinking agent; step 3, scrape the water-based environmental protection decorative surface coating on the wall, scrape it flat, and dry naturally . The exterior wall decoration surface obtained by adopting the exterior wall surface decoration method provided in the present application has a low VOC waste gas emission, can absorb VOC waste gas itself, and shortens the waiting period for house decoration.

Description

technical field [0001] The present application relates to the technical field of wall decoration, and in particular, to a method for decorating a green and environment-friendly exterior wall. Background technique [0002] The modern exterior wall decoration is mainly to paint the base wall with decorative paint for the purpose of beautification and decoration. The specific operation of exterior wall decoration is as follows: by selecting decorative paints of different colors, painting them on the base wall, and forming corresponding patterns on the base wall, so as to play the role of decoration and beautification. [0003] At present, the most common decoration method in the field of building decoration is: first, the surface of the original wall is polished, and the depressions are filled with gypsum; then the surface is scraped and coated with a layer of putty powder, the surface flatness is adjusted, and finally the corresponding decoration is applied. Paint, that is, t...
