Abstract

The invention discloses super-permeable pressure sensitive adhesive and a preparation method thereof, and belongs to the technical field of adhesive. The super-permeable pressure sensitive adhesive comprises main materials, deionized water, emulsifying agent, ammonium hydrogen carbonate, ammonium persulfate, tertiary butyl, rongalite, defoaming agent and thickening agent. The preparation method comprises the following steps of: preparing emulsion; adding the ammonium hydrogen carbonate, the ammonium persulfate and the emulsion at a heating stage; and adding the tertiary butyl, the rongalite, the defoaming agent and the thickening agent at a cooling state, and mixing the materials uniformly to obtain the super-permeable pressure sensitive adhesive. Compared with the conventional pressure sensitive adhesive, the super-permeable pressure sensitive adhesive has the advantages that: the haze of the super-permeable pressure sensitive adhesive is reduced by over 50 percent, the initial viscosity and the enduring viscosity of the super-permeable pressure sensitive adhesive are improved by over 20 percent, and the super-permeable pressure sensitive adhesive has transparent color, has no mixed color and is suitable to be combined with a film to prepare an adhesive tape. The preparation method for the super-permeable pressure sensitive adhesive has simple process, is convenient for operation, and is suitable for large-scale industrialized production.

Description

technical field [0001] The invention belongs to the technical field of glue, and in particular relates to a super-permeable pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the quality requirements of products are getting higher and higher, especially the appearance is also paying more and more attention. The existing pressure-sensitive adhesives generally have a relatively large haze, and they tend to turn yellow after a long time, and the appearance of the adhesive tape is not very transparent after being made into an adhesive tape. There is an urgent need for an adhesive tape with a beautiful appearance, good transparency and no yellowing on the market. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to design and provide a technical solution for a super-permeable pressure-sensitive adhesive and its p...
