Problems solved by technology

[0003] The existing mica tape is generally made of mica paper and glass fiber made of natural mica. The mica paper has very good high temperature resistance and combustion resistance, but the mica paper is easy to absorb water and has poor moisture resistance. It is in a humid environment for a long time. It is easy to absorb water and deteriorate. In order to solve this technical problem, ordinary epoxy resin is usually used to participate in the filling in the prior art, but the compatibility between ordinary epoxy resin and mica paper is poor. In the actual use process It is easy to generate heat, causing energy damage, and the flame retardancy is greatly reduced

Abstract

The invention discloses a high-strength heat-resisting mica tape production technology. The high-strength heat-resisting mica tape production technology comprises the following steps that mica paper is reinforced, a liquid reinforced raw material is prepared, the upper surface and the lower surface of the mica paper are sprayed, the mica paper is dried, cooled and wound after spraying is completed, and the reinforced mica paper is obtained; turning and gluing are carried out, and the upper surface and the lower surface of the reinforced mica paper are coated with binding agents; a manufacturing layer is bonded, and glass fiber cloth is attached to the upper surface and the lower surface of the mica paper to obtain a semi-finished mica tape; drying is carried out, and the semi-finished micatape is placed into an oven for drying; and winding is carried out after cooling, the wound mica tape blank is divided and cut into a band shape and is wound through a dividing and cutting machine, and the high-strength heat-resisting mica tape is obtained. According to the high-strength heat-resisting mica tape production technology, the mica tape manufactured by adopting the technology has highstrength and high combustion performance, has better humidity resistance at the same time, and can be in humid environments for a long time and cannot be corroded and go bad.

Description

technical field [0001] The invention relates to the field of mica tape manufacturing, in particular to a production process for high-strength heat-resistant mica tape. Background technique [0002] Mica tape, also known as refractory mica tape, is made by (mica tape machine). It is a kind of fire-resistant insulating material. 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. According to mica, it can be divided into: synthetic mica tape, phlogopite mica tape, and muscovite tape. Mica tape for fire-resistant safety cables is a high-performance mica insulation product with excellent high temperature resistance and combustion resistance. [0003] The existing mica tape is generally made of mica paper and glass fiber made of natural mica. The mica paper has very good high temperature resistance and combustion resistance, but the mica paper is easy to absorb water and has poor moist...
