Abstract
The present invention provides a kind of preparation method of high pressure vacuum gate spool, fiberglass base fabric and epoxy resin are 1 by weight:Evacuation process is poured into a mould after 1 1.5 mixing；The high pressure vacuum gate spool can prevent the corrosion of SF6 gases for a long time, can continue to keep high-voltage performance for a long time；The preparation method of the high pressure vacuum gate spool, simple for process, the product obtained does not have any stomata; partial discharge can be reduced, the corrosion of SF6 gases can be prevented for a long time, can continue to keep high-voltage performance for a long time; belong to the essential product of high pressure industry, be suitble to the needs of scale industrial production.
Description
Technical field
The present invention relates to high pressure vacuum gate spool production field, especially a kind of preparation method of high pressure vacuum gate spool.
Background technology
Vacuum casting is the method that the molten steel of melting in an atmosphere is injected in the indoor ingot mould of vacuum to ingot of casting,
Also it is vacuum-casting.Vacuum casting method is that product mold is placed in vacuum tank, is decompressed to 133Pa, and liquid sizing material is poured with vacuum
Device injection model is noted, is then sulfided into product.Vacuum casting is not easy to carry air secretly, suitable for the higher product of quality requirement.Very
Empty gate spool is essential utensil in vacuum casting technique, so it is high to its corrosion resistance and high-voltage performance requirement.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of preparation method of high pressure vacuum gate spool.
In order to solve the above technical problems, the technical scheme is that：
A kind of high pressure vacuum gate spool, is made of fiberglass base fabric and epoxy resin, the fiberglass base fabric and asphalt mixtures modified by epoxy resin
The weight ratio of fat is 1:1-1.5.
Preferably, the weight ratio of above-mentioned high pressure vacuum gate spool, the fiberglass base fabric and epoxy resin is 1:1.2.
The preparation method of above-mentioned high pressure vacuum gate spool, is as follows：
(1) obtain fiberglass base fabric by prescription amount and epoxy resin is spare；
(2) after fiberglass base fabric and epoxy resin being mixed by evacuation process casting complete to get.
The beneficial effects of the invention are as follows：
The preparation method of above-mentioned high pressure vacuum gate spool, simple for process, the product obtained does not have any stomata, can drop
Low partial discharge can prevent the corrosion of SF6 gases for a long time, can continue to keep high-voltage performance for a long time, it is essential to belong to high pressure industry
Product is suitble to the needs of scale industrial production.
Specific embodiment
Technical solution of the present invention is further described with reference to specific embodiment.
Embodiment 1
A kind of high pressure vacuum gate spool is made of fiberglass base fabric (glass-fiber-fabric) and epoxy resin, the fiberglass base fabric
Weight ratio with epoxy resin is 1:1.2.
The preparation method of above-mentioned high pressure vacuum gate spool, is as follows：
(1) obtain fiberglass base fabric by prescription amount and epoxy resin is spare；
(2) after fiberglass base fabric and epoxy resin being mixed by evacuation process casting complete to get.After testing, institute
High pressure vacuum cast pipe surface without any stomata, be immersed in 10%NaOH 7 days without blistering or corrosion phenomenon.
The above-mentioned detailed description carried out with reference to embodiment to a kind of preparation method of high pressure vacuum gate spool, is illustrative
Rather than it is limited, can include several embodiments according to limited scope, therefore not depart from overall structure of the invention
Change and modification under thinking, should belong within protection scope of the present invention.
