Embodiment 1

[0019] A highly wear-resistant insulating paper tape, comprising an adhesive layer 1, a rubber layer 2, a paper layer 3 and a wear-resistant layer 4 that are laminated and compounded in sequence from top to bottom, wherein the thickness of the rubber layer 2 is 0.5mm, which is nitrile butadiene The mixed rubber layer obtained by mixing rubber and silicone rubber in a ratio of 3:1, nitrile rubber has excellent oil resistance, wear resistance, heat resistance and strong adhesion, but its disadvantage is poor low temperature resistance. The mixing of silicone rubber can effectively improve its low temperature performance; the paper layer 3 is kraft paper; the wear-resistant layer 4 is a glass fiber cloth layer with a thickness of 50 μm, and the glass fiber cloth layer and the paper layer are adhered to each other. The mixture is bonded together, and the adhesive used is the same as the composition of the adhesive layer 1 .

[0020] The components of the adhesive layer 1 are adhes...

Embodiment 2

[0022] The difference from Example 1 is that the thickness of the rubber layer 2 is 1.5 mm, wherein the mixing ratio of nitrile rubber and silicone rubber is 5:1; the thickness of the glass fiber cloth layer is 100 μm.

Abstract

The invention discloses a high wear-resisting insulation paper adhesive tape. The high wear-resisting insulation paper adhesive tape comprises a gel layer, a rubber layer, a paper layer and a wear-resisting layer which are orderly laminated and compounded from top to bottom, wherein the rubber layer is a mixed rubber layer of nitrile rubber and silicon rubber, the wear-resisting layer is a glass fiber cloth layer, and the glass fiber cloth layer is integrated with the paper layer through the bonding of an adhesive. The high wear-resisting insulation paper adhesive tape disclosed by the invention has the following advantages: 1) the mixed rubber layer of the nitrile rubber and the silicon rubber is adopted so that the adhesive tape has good heat resistance and cold resistance, and the proper working temperature range is -30 to 130 DEG C; 2) a layer of glass fiber cloth is adhered at outside of the paper layer so as to effectively improve the wear-resisting property of the adhesive tape. The adhesive tape disclosed by the invention has the advantages of being high-low temperature resistant, wear-resisting and high in strength, and can be widely applied to the fields such as transformers, vacuum electroplating and generator insulation and the like, and the use range is broadened.

Description

technical field [0001] The invention relates to the field of insulating tapes, in particular to a highly wear-resistant insulating paper tape. Background technique [0002] In the field of oil-type transformers, two insulating cardboards are bonded together by insulating tape, which has the characteristics of easy operation and can significantly improve work efficiency, and has been widely used in the industry. However, the existing insulating tapes used for the above-mentioned functions still have the following problems: 1. The high temperature resistance is insufficient, and it is easily deformed in the transformer oil higher than 105 ° C; 2. The paper layer is used as the base material, and the wear resistance is poor. easily damaged. SUMMARY OF THE INVENTION [0003] The main technical problem to be solved by the present invention is to provide a high wear-resistant insulating paper tape, which can solve the above problems existing in the existing insulating paper tap...
