Description

Technical Field

[0001] The present invention relates to the technical field of insulating agent preparation, and specifically relates to a nano-scale high-weather-resistant insulating agent and its preparation equipment. Background Art

[0002] The main raw materials of insulating agents include resins, fillers, modifiers, auxiliaries, curing agents, etc. Insulating agents are widely used in the fields of electronics, electricity, machinery, and construction. In the power industry, insulating agents can be used to make isolation materials for electrical equipment, cable joints, and lead terminals; in machining, they are used for surface anti-corrosion and bonding of metal parts; in the construction field, they are used to make waterproof materials and floor materials, etc.

[0003] A Chinese invention patent with the publication number CN118122185A discloses an epoxy resin composite insulating adhesive preparation device and process, which is applied in the technical field of insulating adhesive preparation. In the present invention, by setting a bracket in cooperation with a preparation tank, it is convenient to pour the preparation tank along the bracket to pour out the internal materials. The set top cover in cooperation with the mixing shaft can facilitate the stirring action through the stirring blades. When in use, the materials are put into the interior of the preparation tank. The first driving motor can drive the mixing shaft to rotate to drive the stirring blades to rotate inside the preparation tank. The set second driving motor drives the rotating shaft and the push-pull rod to rotate along the sliding sleeve through a crankshaft, which can facilitate the reciprocating movement through the push-pull rod, and at the same time drive the sliding rod to move along the inner side of the movable groove, so as to drive the outer shaft connected thereto to be pulled accordingly, and drive the stirring blades to move vertically through the spring reset, achieving the effect of reducing the stirring dead angle in the preparation tank.

[0004] In addition, during the process of mixing polysilazane resin and epoxy resin in ethyl acetate, the resin particles themselves have a certain surface energy, and there are interaction forces such as van der Waals forces between the particles. When the particles approach each other, these interaction forces will cause them to tend to aggregate together and form lumps. Moreover, factors such as the irregular shape and rough surface of the particles will increase the contact area between the particles, further enhancing this aggregation trend. At the same time, when the stirring intensity is insufficient and the stirring method is inappropriate, insufficient shear force cannot be provided to disperse the particles, resulting in the particles being easily collided with each other and aggregated together to form lumps, and thus the material particles cannot be mixed evenly. In addition, during the process of dissolving polysilazane resin and epoxy resin in ethyl acetate, long-term stirring is required. Since the temperature of the solution will increase during the process of dissolving polysilazane resin and epoxy resin in ethyl acetate and during the stirring process of the stirrer, it is easy to cause the evaporation rate of ethyl acetate to accelerate, affecting the content of ethyl acetate. Therefore, the epoxy resin composite insulating adhesive preparation device and process disclosed in Chinese invention patent CN118122185A cannot prevent the aggregation of material particles and also cannot promote the solubility of polysilazane resin and epoxy resin in ethyl acetate.

[0057] Step 4: Add porous hollow particles, and continue to stir through the processing device to obtain the nano-scale highly weather-resistant insulating agent.

[0058] Example 2:

[0059] Refer to the attached Figures 1 to 12 As shown, a nano-scale highly weather-resistant insulating agent and its preparation equipment include a driving unit 100, including a processing table 101 and a transmission mechanism 102 arranged on the processing table 101;

[0060] A processing unit 200, including a detector 201 arranged on the processing table 101, there is an electrical connection relationship between the detector 201 and an external control device, and a stirring mechanism 202 arranged on the processing table 101; and,

[0061] A feeding unit 300, including a feeding plate one 301 symmetrically and fixedly connected to the processing table 101, a cover plate 302 clamped at the top end of the inner cavity of the feeding plate one 301, and a feeding mechanism 303 arranged at the bottom of the feeding plate one 301.

[0062] Furthermore, the transmission mechanism 102 includes a processing box 102a fixedly connected to the bottom end of the processing table 101.

A sliding groove 202f is formed inside the moving rod 202d. A first sliding rod 202g is slidably connected to the inside of the sliding groove 202f. A sealing strip is provided at the connection between the first sliding rod 202g and the moving rod 202d. The size of the sliding groove 202f is adapted to the size of the first sliding rod 202g. Both ends of a first spring 202h are fixedly connected to the first spring 202h. The two ends of the first spring 202h are respectively fixedly connected to the sliding groove 202f and the first sliding rod 202g. Folding plates 202i are fixedly connected between the two stirring paddles 202e in a circular array.

[0065] It should be noted that: two scraping grooves are symmetrically opened on the outer wall of the stirring block 202b, and the outer ends of the scraping grooves are provided with beveled edges, so that the stirring block 202b can fit into the cylindrical groove opened inside the processing box 102a. Through the beveled edges at the outer ends of the scraping grooves, the particles attached to the surface of the cylindrical groove can be scraped off, and the scraped particles can be introduced into the inner side of the stirring block 202b for stirring.

[0066] Furthermore, the feeding mechanism 303 includes a groove 303a opened inside the feeding plate 1 301, the groove 303a is in the shape of a trapezoid with a wide top and a narrow bottom, the bottom of the groove 303a is penetrated by a sliding rod 303b which is slidably connected, the sliding rod 303b penetrates and slides on the top of the processing table 101, the top of the sliding rod 303b is fixedly connected with a shielding block 303c, the size of the shielding block 303c is adapted to the size of the groove 303a, the top of the inner side of the processing table 101 is slidably connected with a slide plate 303d, the bottom end of the sliding rod 303b is sleeved with a spring 303e, and the two ends of the spring 303e are respectively fixed to the slide plate 303d and the processing table 101 The slide plate 303d is connected with a 303f in the middle of the lower surface, and 303f is in contact with the connecting rod 102i. A 303g is fixedly connected through the outer wall of the feeding plate 1 301, and a feeding plate 2 303h is fixedly connected through the outer wall of the processing box 102a. The bottom end of 303g is fixedly connected to the inside of the feeding plate 2 303h, and the baffle 303i is symmetrically fixedly connected to the lower surface of the inner cavity of the feeding plate 2 303h. The top end of the connecting rod 102i is rotatably connected to the hinged plate 1 303j, the bottom end of the hinged plate 1 303j is rotatably connected to the hinged plate 2 303k, and the bottom end of the hinged plate 2 303k is rotatably connected to the piston plate 303l.

[0067] It should be noted that: limiting grooves are symmetrically provided on the inner wall of the feeding plate 303h, and two protrusions are symmetrically arranged on the outer wall of the piston plate 303l. The protrusions slide inside the limiting grooves, so that the piston plate 303l slides inside the feeding plate 303h. By sliding the protrusions inside the limiting grooves, the piston plate 303l can open and close the feeding port of the feeding plate 303h.

[0068] The following is the working process and principle of the above embodiment:

[0069] The initial state is as follows: the bottom end of the connecting rod 102e is below the processing box 102a, the folding plate 202i is in an uncontracted state, the spring 202h is in an unstretched state, the sliding rod 2 303b is in an uncompressed state, and the outer wall of the blocking block 303c is not in contact with the groove 2 303a.

[0070] The working steps are as follows:

[0071] The operator first puts ethyl acetate into the interior of the processing box 102a through the baffle 303i. Subsequently, the cover plate 302 is opened and polysilazane resin particles and epoxy resin particles are respectively put in. Finally, the operator controls the output end of the processing box 102a to start working through an external control device, so that the processing box 102a drives the first drive rod 102d to rotate, and the first drive rod 102d drives the first linkage rod 102e and the second drive rod 102f to rotate synchronously.

[0072] During the rotation of the first linkage rod 102e, the bottom end of the first linkage rod 102e rotates outside the processing box 102a with the second drive rod 102f as the axis, causing the top end of the first linkage rod 102e to move up and down reciprocally. The first linkage rod 102e drives the first fixing plate 102g and the hinge block 102h to move up and down reciprocally. Furthermore, the hinge block 102h drives one end of the second linkage rod 102i rotatably connected thereto to move synchronously, causing the second linkage rod 102i to start rotating with the support rod 102j as the axis. The end of the second linkage rod 102i away from the hinge block 102h drives the hinge plate one 303j rotatably connected thereto to move synchronously, causing the hinge plate one 303j to drive the hinge plate two 303k to move synchronously. Furthermore, the hinge plate two 303k drives the piston plate 303l to slide reciprocally inside the second feeding plate 303h. As a result, the piston plate 303l intermittently closes the feeding port of the second feeding plate 303h. By intermittently blocking the feeding port of the second feeding plate 303h with the piston plate 303l, the temperature of the reaction of polysilazane resin and epoxy resin in the ethyl acetate solution can be released, preventing the problem of accelerated volatilization of ethyl acetate due to too high a temperature of the solution, and improving the utilization rate of ethyl acetate.

[0073] Meanwhile, during the rotation of the second linkage rod 102i around the support rod 102j as the axis, the second linkage rod 102i repeatedly contacts 303f, causing 303f to drive the slide plate 303d to reciprocate up and down on the inner wall of the processing table 101. The slide plate 303d drives the second slide rod 303b to reciprocate up and down inside the processing table 101 and the first feeding plate 301, thereby causing the slide plate 303d to repeatedly squeeze the second spring 303e. Further, the second slide rod 303b drives the shielding block 303c to move synchronously inside the second groove 303a, causing the shielding block 303c to intermittently block the second groove 303a during the movement. When the shielding block 303c moves to a position where the second groove 303a is no longer blocked, the particles inside the second groove 303a slide downward through the gap between the shielding block 303c and the second groove 303a and enter the inside of 303g. Then, the particles enter the second feeding plate 303h through 303g and finally fall onto the side of the baffle 303i away from the second hinge plate 303k respectively, and then slide into the inside of the processing box 102a through the inclined angle for processing. In addition, the detector 201 detects the volume of solution particles inside the processing box 102a and controls the rotation speed of the processing box 102a and the feeding frequency, avoiding the problem of a large amount of material particles being put in at one time and preventing the problem of agglomeration when the material particles cannot be quickly dissolved.

[0074] During the rotation of the first transmission rod 102d driving the second transmission rod 102f, the second transmission rod 102f drives the cross 202a and the stirring block 202b to rotate synchronously inside the processing box 102a. The cross 202a drives the first fixed rod 202c to rotate synchronously, the first fixed rod 202c drives the first slide rod 202g engaged with it to rotate synchronously, the first fixed rod 202c drives the moving rod 202d to rotate synchronously, and the moving rod 202d drives the stirring paddle 202e to rotate. During the rotation of the stirring paddle 202e, under the impact of the solution, it moves towards the middle on the outer walls of the first fixed rod 202c and the first slide rod 202g, causing the stirring paddle 202e to drive the folding plate 202i to contract. By stirring the solution inside the processing box 102a with the stirring paddle 202e, the dissolution rate of polysilazane resin and epoxy resin in ethyl acetate solution can be accelerated. By compressing the folding plate 202i, the cutting distance between the cutting positions of the folding plate 202i is changed, enabling the folding plate 202i to effectively cut polyblock particles of different volumes and preventing the polyblock particles from being too large in volume to affect the preparation efficiency of the insulating agent.
