Description
Technical field
The present invention relates to a kind of manufacturing methods of special-shaped mica part, in particular to it is Celsius that a kind of operating temperature reaches 500
The manufacturing method of degree and 1000 degrees Celsius of special-shaped mica part.
Background technique
Using mica as abnormity mica part made of substrate, due to good resistance to compression, anti-folding, anti-corrosion, shock resistance and
Thunder-lightning, arc protection, height insulation, low temperature resistant (- 60 DEG C) are hereinafter, 250 DEG C of high temperature resistant equal excellent performances, are widely used in navigating
It, aviation, military project, nuclear power, radar electrical power trans mission/distribution system, lightning protection electrical engineering and submarine, automobile, shipbuilding, super-pressure transmission net etc.
High-tech applications.With the fast development of new and high technology, application field can more extensively.
This special-shaped mica part of prior art manufacture is molten through dry exclusion with individual mica paper dipping organic siliconresin
It is overlapped one by one after agent by thickness requirement (usually hundreds of Zhang Naizhi numbers thousand are opened), is sent into hot press the compacting passed through about 24 hours
Process is made the plate for manufacturing special-shaped mica part, then plate is cut into polygon block by outer dimension, is then added by machine
Work center carries out multiple programs and fabricates, and there are many deficiencies for this manufacturing method, mainly:
1, process is complicated and period length, waste of raw materials are big, and manufacturing cost is high；
2, plate is to open single layer mica paper by hundreds of Zhang Naizhi numbers thousand to suppress, and is easily layered in processing, any one adds
Work process all can make part rejection to preceding cutting most abandoning due to layering；
3, binder is organic siliconresin, and long-term operating temperature is of limited application less than 250 DEG C.
It is especially different to high temperature resistant in order to adapt to demand of the modern science and technology to high-temperature insulation material of high speed development
The demand of shape mica part, the manufacturing method for providing a kind of special-shaped mica part are particularly important.
Summary of the invention
The object of the present invention is to provide a kind of manufacturing method of special-shaped mica part, processing week simple with manufacturing process
Phase is short, will not be layered, be broken in process, high yield rate, the advantages that loss is few.The present invention is opposite due to forming solidification temperature
It is low, not only save the excellent performance of conventional machining process product obtained, and long-term operating temperature can be improved to 500~
1000 DEG C or more.
The invention discloses a kind of manufacturing methods of special-shaped mica part, are at normal temperature pressed and molded blank, wherein adopt
With water-soluble binder, curing process is completed by tunnel type baking oven, solidification temperature is less than 250 DEG C, curing process of the invention
Disposably to be completed by time, temperature in tunnel type baking oven by intelligent control, can continuity continuous productive process, since solidification temperature is small
