Abstract

The invention relates to a hydrogen-sensitive discoloration detection adhesive tape, and a preparation method and application thereof, concretely relates to a self-adhesive tape, concretely relates toa self-adhesive tape capable of generating color change under hydrogen contact, and further relates to a preparation method and an application method of the self-adhesive tape. The self-adhesive tapeis intrinsically safe, simple and convenient to fix, and simple and visual in a visual representation mode, the position of a leakage point can be indicated through local discoloration, the defects that the positioning capability of a pressure loss hydrogen leakage detection leakage detection point is limited and tiny leakage is difficult to find are overcome, the defect that electronic hydrogendetection equipment is high in layout cost is overcome, a common hydrogen leakage detection method is supplemented, the time cost for finding the leakage position after leakage occurs is greatly reduced, the emergency response is improved, and extremely high application and popularization value is achieved.

Description

technical field

[0001] The invention relates to a hydrogen-sensitive color-changing detection tape and its preparation method and application, in particular to a self-adhesive tape, in particular to a self-adhesive tape that can change color when exposed to hydrogen, and to a self-adhesive tape The preparation method of the adhesive tape and the method of use. Background technique

[0002] With the development of hydrogen production and hydrogen storage technology, hydrogen energy has developed into the most potential clean energy in the 21st century. The product of its high combustion calorific value is water, the cleanest energy. Widely sourced and renewable. However, the explosion limit of hydrogen is wide, ranging from 4% to 75%, and a strong explosion can occur when it encounters an open flame. At the same time, the hydrogen molecule is very small, and it is very easy to leak during production, transportation and storage. Therefore, in the storage and transportation...
