Abstract

The invention relates to a double-sided reinforced mica tape with films. The mica tape sequentially comprises a first organic film layer, a first adhesive layer, mica paper, a second adhesive layer and a second organic film layer from bottom to top. The double-sided reinforced mica tape with the films has the advantages that the double-sided reinforced mica tape is low in manufacturing cost, high in surface abrasion resistance, sufficient in strength and proper in elongation, and an insulating property of the mica paper cannot be destroyed even when the double-sided reinforced mica tape is burned; as tested by experiments, the tensile strength of the mica tape is higher than or equal to 30N, the breaking strength of the mica tape is higher than or equal to 100N, and the mica tape can be used for motors.

Description

technical field [0001] The invention belongs to the technical field of mica tape preparation, and in particular relates to a double-sided reinforced film mica tape and a preparation method thereof. Background technique [0002] Mica tape, also known as refractory mica tape, is a fire-resistant insulating material, which can be divided into: mica tape for motors and mica tape for cables. According to the structure, it is divided into: double-sided belt, single-sided belt, three-in-one belt, double-film belt, single-film belt, etc. [0003] The development of modern large and medium-sized high-voltage motor technology has put forward higher and higher requirements for the insulation performance of the motor. The operating temperature, rated power, capacitance and volume of the motor have increased significantly, and the insulation structure has to bear higher electrical stress, mechanical stress, thermal stress and environmental stress, and the working environment of the moto...
