[0008]

[0009] The kaolin is calcined kaolin with a mesh size of 5000. When working, cloves and camphor are used to drive away termites and rats by their smell, effectively protecting the normal operation of the cable. At the same time, the kaolin has a certain flame retardancy, which can prevent the cable from catching fire quickly when a fire occurs, and has a certain delay effect. At the same time, 10% cypermethrin emulsifiable concentrate is mixed in the sheath layer, which can kill some insects that are not sensitive to odors, further protecting the cable.

[0010] A method for preparing an ant-proof flame-retardant cable, which is suitable for preparing the above-mentioned sheath layer, and the preparation method is as follows:

[0011] S1: First, low-density polyethylene, zinc stearate, modified polyurethane elastomer, light calcium carbonate and antioxidant are sequentially placed into the barrel of the mixer through the feed port, the motor is turned on, the upper and lower materials are tumbled by the stirring of the arc plate, and the mixture is mixed and stirred for 30-50 minutes to obtain a mixture A;

[0012] S2: Put cloves, camphor and kaolin into the barrel through the feed port in sequence, and stir for 10-20 minutes to obtain a mixture B;

[0013] S3: Then 10% cypermethrin emulsifiable concentrate is slowly poured in from the feed port, stirred for 5-10 minutes, and then the block is moved upward to allow the barrel material to flow out from the discharge port to obtain a mixture C;

[0014] S4: Add the mixture C into an internal mixer for internal mixing, set the material temperature to 170° C.-180° C., and internal mix for 8-10 minutes to obtain a blend D, and then put the blend D into a twin-screw extruder for extrusion and coating on the water-blocking layer to form a sheath layer.

[0015] Preferably, the mixer includes a barrel body; a motor is fixedly connected to the top of the barrel body; a first rotating shaft is provided at the output end of the motor, and the first rotating shaft extends into the barrel body; a group of stirring columns are rotatably connected on the shaft located in the barrel body; the stirring columns are arranged tilted downward, and a first gear is fixedly connected to the stirring columns; a group of annular blocks are fixedly connected to the barrel body; a first inclined surface begins to be provided on the side wall of the annular block; the first inclined surface and the stirring column are parallel to each other; the top of the annular block is an arc surface; a pair of symmetrically distributed feeding ports are provided at the top of the barrel body; a first rack is fixedly connected to the first inclined surface; the first rack and the first gear are meshed with each other; in the prior art, when materials are mixed through a mixing device, a stirring rod is generally used for stirring, but when the stirring rod is stirred, a straight plate is generally used for stirring the materials horizontally, which will cause the materials to be unable to turn up and down, which will cause the materials to be more obviously stratified, affecting the mixing quality, and at the same time, when the straight plate is used for stirring, there is a gap between the upper and lower straight plates.

[0056] like Figure 4 , Fig. 9 and Fig.10 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a discharge port 53 is provided at the bottom end of the barrel body 1; a lead screw 55 is fixedly connected to the bottom end of the first rotating shaft 12; the lead screw 55 is connected to a stopper 54 through a lead screw nut pair; the cross-sections of the discharge port 53 and the stopper 54 are inverted cones; an annular groove 56 is provided at the bottom end of the stopper 54; a fixing rod 62 is fixedly connected to the side wall of the discharge port 53; the fixing rod 62 is slidably connected in the annular groove 56; a pair of second slide grooves 59 are provided in the inner ring wall of the annular groove 56; a second concave groove 59 is provided on the fixing rod 62 Groove 57; a magnetic block 58 is fixedly connected to the bottom of the second groove 57 through a spring; an electromagnetic layer 6 is fixedly connected to the bottom of the second slide groove 59; when the electromagnetic layer 6 is energized, the electromagnetic layer 6 and the magnetic block 58 attract each other; during operation, when discharging is required, the electromagnetic layer 6 is energized, and then the magnetic block 58 is allowed to enter the second slide groove 59, and then the screw is rotated to move the block 54 upward to allow the material to be discharged. At the same time, the electromagnetic layer 6 can be used to control the upward movement distance of the block 54, thereby controlling the discharging rate. The operation is simple and convenient, avoiding manual opening of the material, and can also effectively control the discharging rate.

[0057] Working principle: After the material is put into the barrel body 1 through the feed port 18, the motor 11 is started, and the motor 11 drives the first rotating shaft 12 to rotate. The rotation of the first rotating shaft 12 drives the stirring column 13. When the stirring column 13 rotates, the first gear 17 and the first rack 16 are meshed with each other, thereby driving the stirring column 13 to rotate around the first rotating shaft 12 while rotating. At the same time, because the stirring column 13 is tilted downward, the material can be fully tumbled up and down, and the material can be mixed evenly up and down. The up and down tumbling action can be used to stir the material in the barrel body 1 in an all-round way to avoid the occurrence of stirring dead corners, which can not only improve the quality and efficiency of stirring, but also further stir The comprehensiveness of the invention can save the mixing time of the materials while ensuring the mixing quality. At the same time, the first inclined surface is arranged downward, which can facilitate the meshing of the first gear 17 and the first rack 16. The top of the annular block 15 is arranged as an arc surface, which can effectively avoid the feeding of the materials and avoid the residue of the materials. The first through groove 2 is arranged, and the filaments 21 are arranged in the first through groove 2. The rigidity and toughness of the filaments 21 can be used to conveniently stir the materials while breaking the lumps and agglomerations of the materials by using the filaments 21, so as to ensure the mixing efficiency of the materials. At the same time, it can also avoid the large force area of ​​the arc plate 14 body, which affects the stirring and slapping of the materials. In terms of ensuring the effect of the up and down rolling of the arc plate 14, the force is reduced. The force area can increase the impact force, and the position of the first through groove 2 is filled with the filament 21 to further stir the material; a corrugated groove 22 is provided on the outer plate of the arc plate 14, and a cutting blade 23 is provided in the corrugated groove 22. When the arc plate 14 rotates, the arc plate 14 will be used to hit the material, and the material will flow to both sides of the arc plate 14 while rolling. When it flows to the position of the outer wall of the arc plate 14, it will enter the groove of the corrugated groove 22, and then the mixed material will be cut by the cutting action of the cutting blade 23 to ensure the crushing effect; when the stirring column 13 rotates around the first rotating shaft 12, the pushing ball 42 will contact the semicircular ball 43 at this time, and then push the pushing ball 42 to the first groove 4 direction, and then a group of balls 32 will be pulled by the first elastic rope 34, and then the planes of the balls 32 and the baffle 44 will collide with each other, and at the same time, the arc block 33 will be pushed toward the arc groove 31 to extend the cutting blade 23, and then when the semi-circular balls 43 and the pushing balls 42 are staggered, the moving column 41 will move outward under the action of the spring, and then drive a group of balls 32 to move through the second thin rope 36, so that the balls 32 and the inner concave surface of the baffle 44 collide with each other, and the arc block 33 drives the cutting blade 23 to contract, and then the cutting blade 23 moves back and forth, and at the same time, the back and forth collision of the balls 32 and the baffle 44 is used to avoid fine and broken materials attached to the arc plate 14, so as to ensure the neatness of the arc plate 14;When the ball 32 moves back and forth in the arc cavity 3, it will drive the slide post 61 to move back and forth in the first slide groove 52. The slide post 61 will contact the elastic sheet 5 and then collide with it. At the same time, the elastic sheet 5 is Y-shaped, and the slide post 61 can collide with the elastic sheet 5 back and forth. The elastic sheet 5 is provided with a convex block 51, which can increase the local vibration of the elastic sheet 5. When the elastic sheet 5 vibrates, the vibration force can be transmitted to the filament 21. The vibration of the filament 21 can increase the cutting force of the filament 21, and can also perform self-cleaning treatment on the filament 21; when it is necessary to discharge the material, the electromagnetic layer 6 is energized, and then the magnetic block 58 is allowed to enter the second slide groove 59, and then the screw rod is rotated to move the block 54 upward, so that the material can be discharged. At the same time, the electromagnetic layer 6 can be used to control the upward movement distance of the block 54, thereby controlling the discharge rate. The operation is simple and convenient, avoiding manual opening of the material, and can also effectively control the discharge rate. ;
