Preferably, from type membrane one end fixedly connected with tear tape, tear tape with be the vertical state from the type membrane, the setting up of tear tape makes things convenient for constructor to tear off from the type membrane.

Preferably, the one end that the release liner was kept away from to the tear tape bonds with the backing fiberboard main part mutually, the tear tape surface is carved with the tear sign, and the tear sign be provided with do benefit to the guide constructor and find the tear tape fast.

In the technical scheme, the utility model provides a technological effect and advantage:

through set up splice and splice groove in the backing fiberboard main part to set up spacing arch and spacing recess respectively on splice and splice groove, splice can guide the backing fiberboard with the splice groove and splice each other, and make spacing arch and spacing recess joint each other together, improved the connection compactness between the backing fiberboard, be favorable to promoting the protection effect of backing fiberboard to the storage tank inner wall.
