Problems solved by technology

[0003] At present, there are no relevant standards for the technical requirements of the gloss uniformity of water-based polymer wall coating materials, and there is no testing method for the gloss uniformity of water-based polymer wall coating materials. Generally, large-scale simulated construction is only used to detect water-based polymers. Will the wall coating materials have obvious blooming phenomenon? This is inefficient, time-consuming, and material-intensive

Embodiment 1

[0053] Example 1 Water-based polymer wall coating material construction uniformity measurement (85 ° gloss difference ≤ 0.5)

[0054] Under the conditions of temperature 23°C±2°C and relative humidity 50%±5%, according to the above test method of gloss uniformity, respectively viewed from the front and side, and measured the first coat and the third coat 60° and 85° gloss as image 3 As shown in A, the first pass: (2.4,2.9), the third pass: (2.4,3.2).

[0055] Then carry out large-scale indoor construction tests on the samples. The tests are carried out according to conventional conditions and procedures. The results after construction are as follows from the side. image 3 Shown in B.

[0056] Judgment of results: From the gloss difference test results of this sample, it can be seen that the 85° difference between the first pass and the third pass is 0.3≤0.5, and the gloss is relatively uniform when viewed from the front and side. In the large-area construction test, viewe...

Abstract

The invention discloses a method for rapidly detecting the construction uniformity of a water-based polymer wall covering material. Specifically, the present invention simulates the construction uniformity of the waterborne polymer wall covering material by brushing the polymer wall covering material multiple times on the glass sheet, so as to quickly detect the construction uniformity of the coating, and can prevent the waterborne polymer wall covering from being coated. The problem of uneven gloss after the construction of the cladding material.

Description

technical field [0001] The invention relates to the field of coating detection, in particular, the invention relates to a method for rapidly detecting the construction uniformity of water-based polymer wall coating materials Background technique [0002] With the development of building water-based polymer wall coating materials, the use of water-based polymer wall coating materials is becoming more and more convenient, but it is often seen that the water-based polymer wall coating materials are used on the wall after construction Floating phenomenon occurs on the surface, such as uneven gloss of the paint film, that is, some places have higher gloss, and some places have lower gloss, especially in the overlapping areas of painting. The uneven gloss of the paint film may be caused by several reasons such as inconsistent porosity of the base layer, excessive dilution ratio, use of different batches of products, use of different construction tools, and uneven coating thickness...
