Embodiment

[0125] The technical problem to be solved by the invention is: the selection of adhesion pre-testing test material and the setting of various technical indicators and parameters.

[0126] In order to solve the above-mentioned technical problems, the technical solution provided by the present invention is: prepare a set of double-layer composite adhesive tape and set various technical indicators and parameters.

[0127] Such as figure 1 As shown, the adhesion test composite tape is composed of three parts: the base tape, the surface tape and the backing paper.

[0128] 1. Base tape Y 1 , acting like a layer of latex paint film, its characteristics must have:

[0129] 1. The adhesive force of the adhesive tape (adhesion between the adhesive and the substrate) is the same as that of the tested latex paint. The size of the adhesion of the tested latex paint can use the pull-off test to measure the maximum strength when it is pulled apart.

Abstract

The invention provides a base fastness detection material before coating. The material is an adhesive force testing composite adhesive tape, wherein the composite adhesive tape comprises a base adhesive tape Y1, a surface adhesive tape Y2 and bottom paper, wherein the adhesive force and peel strength of the base adhesive tape Y1 are the same as the adhesive force and peel strength between the coated latex paint and base respectively; the adhesive force and peel strength of the surface adhesive tape Y2 are lower than the adhesive force and peel strength between the coated latex paint and base respectively; the bottom paper, the base adhesive tape Y1 and the surface adhesive tape Y2 are sequentially arranged outwards from the base material; adhesives are arranged among the base adhesive tape Y1, the surface adhesive tape Y2 and the bottom paper. The invention also provides a base fastness detection method before coating.

Description

technical field [0001] The invention relates to a material for on-site detection of the firmness of a base layer before latex paint is applied, and the adhesion ability between the latex paint and the base layer can be predicted through the detection result. Background technique [0002] The firmness, density and surface state of the base layer will have a great influence on the adhesion of the coating film after painting. Therefore, before painting, the surface of the pre-coated base is generally treated, but whether the pre-treated base meets the coating conditions, whether it can maintain sufficient bonding force with the coating film, and will not cause poor adhesion such as peeling and peeling off. . There have been no good tools and materials for a long time, and more rely on the experience of basic inspection personnel. [0003] Therefore, this area lacks a kind of convenient, simple and intuitive material, which can solve the pre-inspection of the actual base layer...
