Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard uses redrafted Law Amendment uses ISO 25179.2010 "Determination of adhesive pressure-sensitive adhesive water or alkali solubility."
This standard compared with ISO 25179.2010, the structural changes are as follows.
--- Added a chapter (Chapter 3)
--- Add one (7.7);
--- Chapter 9 is divided into two, respectively, 9.1 and 9.2;
--- Removed Appendix A
The main technical differences between this standard and ISO 25179.2010 and their reasons are as follows.
--- Normative references, this standard made a technical differences with the adjustment to adapt to China's national conditions, to adjust the situation focus
Reflected in Chapter 2 "Normative references", the specific adjustments are as follows.
● Added GB/T 22396 "pressure-sensitive adhesive terminology," easy to understand;
● Removed ISO 291, written directly in 7.7.
--- Added Chapter 3 terms and definitions, easy to understand.
--- In the choice of test substrate, according to domestic facts, an increase of PET and BOPP, delete kraft paper. To reduce the substrate pair
Interference with adhesive solubility (see 6.3).
--- Wet glue thickness modified to "about 25μm, may also be agreed by both parties" in order to meet the national conditions (see 7.2).
--- Removed Appendix A, the test report does not require separate appendix.

Determination of the solubility of pressure-sensitive adhesives
1 Scope
This standard specifies the method of determination of pressure-sensitive adhesive solubility.
This standard applies to pressure-sensitive adhesives in aqueous solution or alkaline solution solubility determination.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version applies to this article
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 22396 Pressure-sensitive adhesive terminology
3 Terms and definitions
GB/T 22396 defined terms and definitions apply to this document.
4 principle
The pressure-sensitive adhesive is coated on a substrate (such as PET, BOPP), after drying the solvent, a pressure-sensitive adhesive tape sample is made. In water or alkaline
The solution was shaken pressure-sensitive adhesive tape samples, testing the quality of the adhesive loss, measured its solubility.
5 device
5.1 shaker
Shaker used for shaking the sample bottle shaker can be heated to 40 ℃ ~ 80 ℃, the temperature difference is not greater than 2 ℃, and can control the shaking rate of
10r/min ~ 100r/min between. see picture 1.
