A kind of preparation method of communication base station composite manhole cover, which comprises the steps of:
Step 1 stirs at 90-110 DEG C after weighing 40-95 parts of cyanate ester resins, 1-15 parts of plasticized modifier mixing
20-30min naturally cools to room temperature；
Proper amount of acetone solvent is added in the resin solution in step 1 and stirs evenly, adds 1-20 parts for step 2
Curing agent, 1-20 part reinforcing filler, 0.5-10 parts of low shrinkage additives, 0.01-2 parts of catalyst, 0.1-1 parts of lubricants, 0.01-
1 part of UV absorbent, 0.1-0.6 parts of antioxidant, 0.1-0.5 parts of pigment continue to stir 10-30min at room temperature, and it is pre- to obtain resin
Immersion liquid；
Step 3, the resin prepreg liquid that step 2 is obtained are coated in low-k fiber cloth, control fiber content
It is 5-60 parts, removes the acetone solvent in resin, obtain prepreg；
Prepreg is put into preheated inspection well cover mould, molded curing by step 4, obtains high wave-penetrating composite material basement
Well lid.
Present invention optimizes the production methods of well lid can be improved well lid by the cured well lid of integrated die
Integral hardness, it is not easy to break.
In step 1, cyanate ester resin and plasticized modifier are stirred using blender, and inflated in stirring.
By inflating the collision frequency that can increase between material, and then stirring efficiency is improved, shortens mixing time.
It is preferred that first fill air to stirring rate between 1.0-1.3, then inflated with nitrogen to stirring rate between 1.5-2.0.This is specially
Benefit is first filling air again by way of inflated with nitrogen, on the one hand, the dosage of nitrogen can be reduced, so that production cost is reduced, another party
Air is driven out of in later-stage utilization nitrogen, reduces oxygen content to a certain extent, slows down the oxidation rate of material by face.
The blender includes one for stirring the teeter chamber of raw material, and teeter chamber is the container of an opening upwards, container
Top is equipped with a head, and a rotatable agitating shaft is fixed on head, and agitating shaft connects a driving motor by conveyer system
Shaft, and rotated under the drive of driving motor；Agitating shaft is a hollow agitating shaft, and agitating shaft is in hollow tubular, hollow
The upper end opening of pipe, lower end are closed, and are provided with venthole on the side wall of hollow tube；It further include an air pump, the inlet end connection of air pump
Two air inlets of the gas outlet of one three-way valve, three-way valve are separately connected atmosphere and nitrogen gas tank；The outlet side of air pump is connected with one
The other end of gas-guide tube, gas-guide tube is protruded into hollow tube by opening.
This patent is creative to be opened in venthole on agitating shaft, can stir, inflate on one side on one side, achieve following anticipations
Less than technical effect:
1, under the action of agitating shaft centrifugal force, airflow direction is consistent with mixing direction, on the one hand, and stirring resistance is smaller,
Mixing speed is fast, and on the other hand, the mixability of gas and material is high, and nitrogen utilization rate is high；
2, venthole goes out the air-flow formed can play the buffer action of agitating shaft and material to a certain extent, can effectively keep away
Exempt from material to be sticked on agitating shaft, causes situation higher closer to shaft stirring extent, lower further away from shaft stirring extent, make
It stirs more uniform；
3, structure is simple, easy to clean, installation, maintenance.
The upper end of the agitating shaft is cased with first gear, and the first gear connects the second tooth by a transmission gear group
Wheel, the second gear cover in the shaft of driving motor.This patent selects gear as conveyer system, and power is big, and effect is good.
Can certainly should not transmission gear group, directly first gear, second gear are interlocked.To be further reduced component,
Reduce spoilage.
The three-way valve is solenoid valve, and air pump, driving motor, solenoid valve are all connected with a signal processing system, signal processing
System connects a sensor acquisition system, and sensor acquisition system includes a temperature sensor, and hollow tube is a Heat Conduction Material system
At hollow tube, hollow tube is against on the temperature-sensing element (device) of temperature sensor.
Because of the increase with mixing time, while being continuously increased, the temperature of material also rises because of friction stirring rate,
This patent can use the temperature that hollow tube obtains material, and signal processing system judges stirring extent according to temperature, so as to adjust
The working condition of solenoid valve, air pump, driving motor.
The aperture stretched out for agitating shaft can be set on head, the sensing element of temperature sensor is annular in shape, and fixed
In tapping, agitating shaft passes through sensing element, so that sensing element is contacted with agitating shaft, pad is equipped between sensing element and head
Circle, grinds sensing element to avoid the agitating shaft of quick rotation.Stirring extent is different, and the resistance that agitating shaft is subject to can also become
Change, stirring extent can also be judged according to the variation of resistance.It can certainly visually observe.
