Preparation method of graphene umbrella cloth and graphene umbrella

Abstract

The application relates to the technical field of umbrella manufacturing, in particular to a preparation method of a graphene umbrella cloth and a graphene umbrella. The preparation method of the graphene umbrella cloth and the graphene umbrella are provided by adding a dispersant into a graphene solution and then performing ultrasonic oscillation, so that the compatibility of the graphene solution is improved. The preparation method of the graphene umbrella cloth and the graphene umbrella are as follows: S1, material preparation; S2, dispersion; S3, mixing; S4, padding; and S5, drying. In the process of manufacturing the graphene textile cloth, the graphene solution needs to be ultrasonically dispersed first, in order to accelerate the dispersion speed of the graphene solution, the dispersant is added for dispersion, and the dispersed graphene solution can be quickly compatible with the water-soluble polyurethane solution, so that the graphene textile cloth can be manufactured faster.

The ultrasonic oscillator was then started, and the ultrasonic time was 1-1.5 hours to obtain a dispersed graphene solution. S3, Mixed The graphene solution dispersed in S2 was added to a water-soluble polyurethane solution and mixed using a mixer at a temperature of 30-130 degrees Celsius for 20-30 minutes to obtain a graphene masking agent solution. S4, Rolling The fabric base of the umbrella is placed into the immersion tank of the immersion and padding machine, and the graphene masking agent solution is sprayed onto the fabric base of the umbrella. The immersion and padding process is carried out at 20-60 degrees and the immersion and padding time is 20-40 minutes to obtain the graphene textile fabric. S5, Drying The fabric base of the umbrella after being impregnated in S4 is dried at high temperature to obtain the graphene textile fabric finished product, which is the graphene umbrella textile fabric. The graphene umbrella fabric is used to prepare graphene umbrellas. The specific steps for making graphene umbrellas are as follows: B1. Making the umbrella ribs and leaves First, use the equipment to bend the umbrella ribs into an arc shape. Take a hollow tube with a diameter of 14-18mm and cut it into a length of 50-80cm to obtain an umbrella rib rod with a length of 50-80cm and a diameter of 14-18mm. B2. Assemble the umbrella handle and the central rod of the umbrella ribs. The umbrella handle is rotated and inserted into the lower end of the umbrella rib rod using assembly equipment. B3. Assemble the umbrella rib rod and umbrella rib leaves; B4. Sewing The cut umbrella fabric is pieced together and sewn onto the umbrella ribs to obtain the umbrella surface; B5. Assemble the umbrella top. Secure the top of the umbrella to the center of the top of the umbrella canopy; In step B2, the specific process for assembling the umbrella handle and the inner rod of the umbrella ribs is as follows: B2-1. Place the umbrella handle First, pull the pusher (8) to the right to compress the spring (9) and place the umbrella handle in the cavity inside the workbench (1). The leftmost umbrella handle is located inside the fixed frame (7). B2-2, Placement of umbrella ribs and central rods Insert the umbrella rib rod into the upper part of the fixing tube (3), and let the lower end of the umbrella rib rod pass out of the fixing tube (3). B2-3, Drive Parachute Handle The extension rod of the control cylinder (4) extends, causing the threaded rod (5) and the fixed frame (7) to move upward. Under the action of the threaded sleeve (6), the threaded rod (5) and the fixed frame (7) rotate. At the same time, the umbrella handle rotates and rises. The umbrella handle is screwed upward into the bottom end of the umbrella rib rod for assembly. B2-4, Material stop When the threaded rod (5) moves upward, it will drive the puller (13) to move upward and release the blocking frame (11). The blocking frame (11) will block the umbrella handle because the return spring (12) moves upward. B2-5, Loading Material When the telescopic rod of the cylinder (4) shortens, it causes the threaded rod (5) and the fixed frame (7) to move downward. The threaded rod (5) causes the pulling part (13) to move downward. The pulling part (13) then causes the blocking frame (11) to move downward and no longer block the umbrella handle. The pushing spring (9) then pushes the pushing part (8) to move to the left, thereby moving the umbrella handle to the left into the fixed frame (7) for automatic feeding.

2.
