Problems solved by technology

[0003] However, the current mica tapes on the market often have problems such as delamination of mica paper and glass fiber, glass fiber spinning, adhesive anti-adhesion, and mica tape sticking due to poor control of the actual amount of adhesive used; For the mica tape used as a reinforcing material, the organic film is carbonized at high temperature, resulting in poor temperature and electrical resistance, and cannot be used in high-end motors or cables; the glass fiber double-sided tape also has the problem of glass fiber stringing

Embodiment 1

[0020] Choose the quantitative product produced by Hubei Yunshui Technology Co., Ltd. as 120g / m 2 The calcined phlogopite paper, produced by Tongcheng Tongli Company, is 28g / m 2 The glass fiber cloth and the oily silicone release agent sly7458 produced by Dow Corning Company are used to compound the mica paper and the glass fiber cloth on the sizing machine, and after compounding, spray the above-mentioned diluted to 5% on the side of the mica paper The oil-based silicone sly7458 release agent, after drying in a multi-temperature oven, is wound to obtain a phlogopite paper embryo tape, and then cut and wound to make a 10,000-meter non-sticking refractory calcined phlogopite tape CP120G28A-1 .

Embodiment 2

[0022] Choose the quantitative product produced by Hubei Yunshui Technology Co., Ltd. as 120g / m 2 The calcined phlogopite paper, produced by Tongcheng Tongli Company, is 28g / m 2 The glass fiber cloth and the solvent-free SZ220 release agent produced by Guangzhou Chemical Co., Ltd. of the Chinese Academy of Sciences, the mica paper and the glass fiber cloth are first sizing and compounded on the sizing machine, and the above-mentioned solvent-free SZ220 is brushed on the side of the mica paper after compounding The release agent is dried in a multi-temperature section oven, then rolled to obtain a phlogopite paper embryo tape, and then cut and wound to make a 10,000-meter non-sticking refractory calcined phlogopite tape CP120G28A-2.

Embodiment 3

[0024] a. Preparation of release agent

[0025] Take 180 parts of organic silica gel, 6 parts of bismaleimide, 120 parts of high-viscosity methyl silicone oil, 4 parts of anchoring agent, 2 parts of antioxidant and 90 parts of toluene, mix well, and then drop 4 parts of platinum catalyst into it to obtain The release agent.

[0026] b. Choose the quantitative product produced by Hubei Yunshui Technology Co., Ltd. as 120g / m 2 The calcined phlogopite paper, produced by Tongcheng Tongli Company, is 28g / m 2 The glass fiber cloth of the present invention and the self-made release agent of the present invention, on the sizing machine, the mica paper and the glass fiber cloth are first carried out sizing and compounding, and after compounding, the self-made film of the present invention diluted to 5% solid content by toluene is applied on the side of the mica paper. After being dried in a multi-temperature oven, the phlogopite paper embryo tape is obtained by winding, and then cut ...

Abstract

The invention discloses a non-reverse-adhesion fire-resistant mica tape and a preparation method thereof. The non-reverse-adhesion fire-resistant mica tape comprises composite paper and a release agent adhered to the side edge of the composite paper, wherein the composite paper is obtained by bonding glass fiber cloth and mica paper through an adhesive surface. The non-reverse-adhesion fire-resistant mica tape can be used for middle-high-end cables and motor wrapping wires, and an excellent method for solving the problems of wire rising, reverse adhesion, wire adhesion, mica powder falling andthe like of a traditional common mica tape in the winding process is provided.

Description

technical field [0001] The invention relates to the field of mica tapes, in particular to a non-anti-sticking refractory mica tape and a preparation method thereof. Background technique [0002] Mica tape is a fire-resistant insulating material that can be used for motors and cables. It can be divided into double-sided tape, single-sided tape, three-in-one tape, single-film tape, double-film tape, etc. It is a high-performance insulating product with excellent Excellent high temperature resistance and combustion resistance are compounded by mica paper and reinforcing materials under the action of organic adhesives. [0003] However, the current mica tapes on the market often have problems such as delamination of mica paper and glass fiber, glass fiber spinning, adhesive anti-adhesion, and mica tape sticking due to poor control of the actual amount of adhesive used; For the mica tape used as a reinforcing material, the organic film is carbonized at high temperature, resultin...
