For that can further appreciate that the contents of the present invention, feature and effect, following embodiment explanation is hereby enumerated.
As shown in fig. 1, a kind of airstrainer that the embodiment of the present invention 1 provides, raw material includes following weight parts
Component: 30~40 parts of graphene, 35~55 parts of activated silica, 15~25 parts of clay, 5~10 parts of the hydrosol, nano silver powder 0.5~
2 parts.
Specifically, clay includes one of kaolin, montmorillonite, sepiolite or combination.
The preparation process of airstrainer, comprising the following steps:
Step S1: material is screened；
Step S2: mixed grinding is carried out to material；
Step S3: ultrasonic melt process is carried out to mixed material；
Step S4: the mixing material after melting is made by mud section by slip drying press；
Step S5: the extruding of mud section is injected into mold；
Step S6: coolant.
Specific preparation process is as described below:
In step S1: the diameter of selected graphene and activated silica is 10-15 nanometers.
In step S2: clay and nano silver powder are added in ball mill jointly and are ground, after being fully ground, by graphene,
Active carbon, clay, the hydrosol, nano-silver powder are mixed, and are sufficiently stirred.
In step S3: being warming up to 350 DEG C melts mixture, in melting process by ultrasonic agitation machine it is continual into
