Abstract

The invention discloses a low-viscosity waterborne paper adhesive tape and a preparation method thereof. The adhesive tape at least comprises a paper base material layer, a surface treatment layer anda pressure sensitive adhesive layer arranged on one side of the paper base material layer at least, wherein the paper base material layer takes a paper material as a main material; the surface treatment layer is formed on at least part of the surface of the paper base material layer and is used for providing the hydrophobic capacity; the pressure sensitive adhesive layer is formed on at least part of the surface of the surface treatment layer and/or the paper base material layer and is used for providing viscosity. The adhesive tape disclosed by the invention has the characteristics of beingstrong in temperature resistance, low in peeling force, good in pasting effect, comfortable in removal hand feeling and the like.

Description

technical field [0001] The invention relates to a low-viscosity water-based paper tape and a preparation method thereof, in particular to a low-viscosity water-based paper tape suitable for paper surfaces, latex paint walls and the like and a preparation method thereof. Background technique [0002] The low-adhesive tape uses masking paper or Japanese paper as the base material. After being coated with pressure-sensitive adhesive glue, it has excellent holding power, is easy to adhere to various surfaces, and is easy to remove. will cause damage. It is suitable for sticking to paper surface, latex paint wall, etc., and used as a mask. [0003] This kind of tape has low viscosity and soft product. It has good adhesion and masking properties to most smooth surfaces, bends or corners. It has good workability and low work intensity. It can be removed quickly after use without leaving any glue residue. . [0004] Traditional washi tape has high viscosity. When it comes to bond...
