Method for testing rain imprint of real stone paint of outer wall

Abstract

The invention relates to the technical field of real stone paint quality detection, in particular to a method for testing rain imprint of real stone paint of an outer wall. The method comprises the following steps: coating a putty layer on the wall body in batches, after putty maintenance, coating primer once in a rolling manner, and transversely fixing the primer on the primer layer at intervals of 23-27 cm in the longitudinal direction by using separation strips of 8-12 mm so that a test area is divided into a plurality of transverse grids; spraying a real stone paint sample to be detected on the primer of the transverse lattice to obtain a real stone paint film sample; wetting the real stone paint film sample to ensure that the surface of the real stone paint film sample is moist; arranging a water drainage pipe on the upper side of the wall body, wherein a water drainage hole is formed in the water drainage pipe, so that water in the water drainage pipe flows down from the top of the wall body through the water drainage hole; and after moisture on the surface of the real stone paint film sample volatilizes, determining the grade. According to the invention, any one kind of outer wall real stone paint can be subjected to low-cost and scientific detection according to needs, and the rain mark resistance of the outer wall real stone paint can be rapidly evaluated.

Description

technical field

[0001] The invention relates to the technical field of real stone paint quality detection, in particular to a method for testing rain marks of real stone paint on exterior walls. Background technique

[0002] Real stone paint is a kind of imitation stone paint prepared from various natural colored sands, emulsions for architectural coatings and various additives. The decorative effect is similar to marble and granite. It has the characteristics of environmental protection, strong adhesion, light fading, etc., and is easy to construct, easy to dry and save time. It has been rapidly developed and applied in my country, and has become one of the leading coating materials in the decoration of building exterior walls in my country.

[0003] There are many problems in the use of real stone paint. The rain mark phenomenon is a paint problem often encountered in the decoration process of real stone paint on exterior walls, and it has become a typical industry difficul...

[0054] Such as figure 1 Shown: The test method for testing the rain marks of real stone paint, the specific steps are:

[0055] S1 putty layer: choose 2m 2 For the outer wall body 7 (180cm×111cm), scrape a layer of anti-cracking rough putty on the outer wall body 7 to obtain a rough putty layer, the thickness of the thick putty layer is 2mm, dry and maintain for 2 days; then continue to scrape a layer of outer wall The fine-bottomed putty for the wall project obtains a fine sub-layer, the thickness of which is 1mm, and continues to dry and cure for 7 days;

[0056] S2 Wall division: Evenly roll coat a layer of textured real stone paint special primer on the delicate sub-layer, and the coating rate is 0.12kg / m 2 , dry and maintain for 6 hours under the condition of no rain after rolling coating; after the primer is dry, use 10mm wide adhesive tape 4 to fix horizontally on the primer on the wall 7 at intervals of 25cm in the longitudinal direction to obtain several horizontal gr...

[0070] Such as figure 1 Shown: The test method for testing the rain marks of real stone paint, the specific steps are:

[0071] S1 putty layer: select 4m 2 For the outer wall body 7 (250cm×160cm), scrape a layer of anti-cracking rough putty on the outer wall body 7 to obtain a rough putty layer. The fine-bottomed putty for wall engineering obtains a fine sub-layer, the thickness of which is 1.5mm, and continues to dry and cure for 6 days;

[0072] S2 Wall division: evenly roll coat a layer of special primer for textured real stone paint on the delicate sub-layer, and the coating rate is 0.15kg / m 2 , dry and maintain for 7 hours under the condition of no rain after roller coating; after the primer is dry, use 12mm wide adhesive tape 4 to fix horizontally on the primer on the wall 7 at an interval of 27cm in the vertical direction to obtain several horizontal grids 5, in which the primer is rolled The construction tool is a 4-inch short wool little finger roller core, and it ...
