preparation example 1

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

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

[0050] The preparation method of waterborne polyurethane environment-friendly primer comprises the following steps:

[0051] In step S1, 6.0kg of diatomaceous earth, 5kg of light calcium carbonate, 6kg of titanium dioxide, 2.8kg of ac...

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 in mass percentage: 25% water-based polyurethane, 2.0% Degussa non-ionic wetting and dispersing agent BREAK-THRU DA 646, 25% deionized water, 1.5% BASF 2190 defoamer, 2.5% Digo substrate wetting agent WET KL245, 3.0% Digo substrate wetting agent WET KL245, 1.5% Wante VANTEX-T, 4.5% polyacrylonitrile-based carbon fiber, 35% environmentally friendly filler. The environmentally friendly filler is composed of 10.5% of diatomite, 8.75% of light calcium carbonate, 10.5% of titanium dioxide, 4.9% of active manganese powder, and 0.35% of zinc oxide whiskers, accounting 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 water-based polyurethane environmental protection primer is prepared from the following raw materials in mass percentage: 25% water-based polyurethane, 2.0% Degussa non-ionic wetting and dispersing agent BREAK-THRU DA 646, 30% deionized water, 1.5% BASF 2190 defoamer, 2.5% Tego 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 filler is composed of 9% diatomite, 7.5% light calcium carbonate, 9% titanium dioxide, 4.2% active manganese powder, and 0.3% zinc oxide whisker, accounting for 9% of the total mass of the water-based polyurethane environmental protection primer.

Abstract

The invention relates to the technical field of wall decoration, in particular to a green and environment-friendly exterior wall surface decoration method. The green and environment-friendly exterior wall surface decoration method comprises the following steps that 1, concave positions of a wall surface are filled and leveled up with gypsum and polished till the wall surface is flat, the wall surface is coated with methyl vinyl silicone rubber in a blade coating mode, and after the methyl vinyl silicone rubber is cured, a rubber cross-linking agent is sprayed; 2, the wall surface is coated with waterborne polyurethane environment-friendly base coat in a blade coating mode, and after the waterborne polyurethane environment-friendly base coat is solidified to be in a gel state, a polyurethane cross-linking agent is sprayed; and 3, the wall surface is coated with water-based environment-friendly decorative finish coating in a blade coating mode, scrape leveling and natural drying are conducted. The external wall decoration surface obtained by adopting the external wall surface decoration method provided by the invention is low in VOC waste gas release amount, and can adsorb the VOC waste gas, so that the waiting period of house decoration is shortened.

Description

technical field [0001] The present application relates to the technical field of wall decoration, in particular to a green and environment-friendly exterior wall decoration method. Background technique [0002] The modern exterior wall decoration is mainly to paint the decorative paint for the purpose of beautifying the decoration on the base wall. The specific operation of exterior wall decoration is as follows: by choosing decorative paints of different colors, painting on the base wall, 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: firstly, the surface of the original wall is polished, and the depression is filled with gypsum; then the surface is scraped and coated with a layer of putty powder to adjust the surface flatness, and finally the corresponding decoration is applied. Paint, that is, to achieve the purpose of ...
