Further as such scheme is improved, and the granularity of the mica powder is less than 30 μm.
Further as such scheme is improved, and the mica powder, graphene in composite material need to be pre-mixed, described
Technology for premixing is：By mica powder be placed on humidity space in be stirred continuously, allow mica powder moisture content 12~15% it
Between, then add graphene and form pre- powder, pre- powder is stirred so as to form standby powder.
Further as such scheme is improved, and the composite material needs to complete within two hours to prepare before use, it is made
Standby process is as follows：After pre- powder is mixed into polyethylene, with baked and banked up with earth less than 90 degrees Celsius 0.5~1.5 it is small when.
Further as such scheme is improved, and tube body includes functional layer and heat-resistant layer from inside to outside.
Further as such scheme is improved, and heat-resistant layer, the mica powder content of the heat-resistant layer is the mica of functional layer
More than one times of powder content.
Further as such scheme is improved, and heat-resistant layer is so manufactured, will under outer surface of tube body molten condition
Mica powder is sprayed on outer surface of tube body.
The beneficial effects of the invention are as follows：A kind of mica powder, graphene composite and flexible pipe, including tube body, the material of the tube body
Matter is composite material, and the composite-material formula includes polyethylene, mica powder, graphene.Due to having mica powder and graphene
Common synergism, allow the present invention flexible pipe have high electrical insulating property, antiacid caustic corrosion, elasticity, toughness and sliding,
The small characteristic of heat-resistant sound-insulation, thermal coefficient of expansion.The present invention is used for oil, the conveying of gas.

Under can be with combination of interactions.
With reference to Fig. 1, this is the embodiment of the present invention, specifically：
A kind of mica powder, graphene composite and flexible pipe, including tube body, the material of the tube body is composite material, described multiple
Condensation material formula includes polyethylene, mica powder, graphene.Due to there is the common synergism of mica powder and graphene, this hair is allowed
Bright flexible pipe has high electrical insulating property, antiacid caustic corrosion, elasticity, toughness and sliding, heat-resistant sound-insulation, thermal coefficient of expansion
Small characteristic.
The granularity of the mica powder of the present embodiment is less than 30 μm.It can be perfectly adhered on graphene, so that micanite
Black alkene, reaches the effect of high electrical insulating property.
In order to realize mica powder attachment good on graphene, mica powder, graphene in composite material need into
Row premixing, the technology for premixing are：Mica powder is placed in the space of humidity and is stirred continuously, allows the moisture content of mica powder
Between 12~15%, then add graphene and form pre- powder, pre- powder is stirred so as to form standby powder.
The composite material needs to complete within two hours to prepare before use, its preparation process is as follows：Pre- powder is mixed into poly-
After ethene, with baked and banked up with earth less than 90 degrees Celsius 0.5~1.5 it is small when, so can guarantee that mica powder, the graphene of pre- powder in storage
Attachment state, and be dried before use, avoid the problem that bubble and decreasing insulating occurs in tube body.
In order to improve insulation performance, tube body includes functional layer 1 and heat-resistant layer 2 from inside to outside.Heat-resistant layer 2, the heat-resistant layer 2
