Problems solved by technology

[0003] There are obvious defects in this method: usually the range of peeling force that can be realized by a kind of latex is very narrow, and pressure-sensitive adhesives with various peeling force strength ranges are usually required during production, which requires a lot of glue to realize, making production The more complicated process is not conducive to large-scale production; the proportion of cross-linking components is closely related to the performance of pressure-sensitive adhesives in all aspects. Changing the proportion of cross-linking components will cause large fluctuations in the performance of pressure-sensitive adhesives, which is very unfavorable for product quality control

Abstract

The invention relates to a formula of acrylic acid emulsion blending pressure sensitive adhesive with continually adjustable stripping resistance. By mixing two kinds of emulsions with different stripping resistance ranges, and adding a cross-linking constituent with a fixed proportion is added, continuous adjustment of the stripping resistance is achieved in a range of 5-500g. With A as a low-viscosity range 5-30 g / 25 mm and B 500-1000 g / 25 mm as a high-viscosity range, the continuous adjustment of the stripping resistance a pressure sensitive adhesive in the range of 5-500g is achieved by blending.

Description

technical field [0001] The invention relates to an emulsion-type pressure-sensitive adhesive formula, in particular to a pressure-sensitive adhesive formula and a preparation method for blending acrylic emulsions with different peeling forces and continuously adjustable peeling force. Background technique [0002] At present, the peel strength of emulsion-type pressure-sensitive adhesives is mainly controlled by adjusting the proportion of cross-linking components. For example, latex A can obtain a peel strength of 5g-30g by adding different proportions of cross-linking components, and other ranges of peeling strength are required. The force is then implemented using Latex B. [0003] There are obvious defects in this method: usually the range of peeling force that can be realized by a kind of latex is very narrow, and pressure-sensitive adhesives with various peeling force strength ranges are usually required during production, which requires a lot of glue to realize, makin...
