Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1 and 2, the present invention mixes the carbon nanotubes with the epoxy resin a, and finally rubs them with hands for more than 30 minutes during the mixing process, and adds the epoxy resin B after the two are fully mixed, and the addition amount of the epoxy resin B is preferably half of that of the epoxy resin a, and then rubs them with hands for mixing, and the rubbing time is about 2 minutes, so as to obtain the nano carbon electrothermal glue 3. It should be noted that, in the carbon nanotube electrothermal glue 3, the weight percentage concentration of the carbon nanotubes is 4wt%, so that the electrical resistance of the carbon nanotube electrothermal glue 3 is about 0.193 ohm and has high viscosity, which is helpful for the carbon nanotube electrothermal glue 3 to adhere to other objects.
Referring to fig. 3, the relationship between the weight percentage concentration of the carbon nanotubes in the carbon nanotube electric heating glue 3 and the thermal diffusion rate is preferably 4wt% because the diffusion rate of the carbon nanotubes is similar to that of the carbon nanotubes 3wt% and 4wt%, but the higher the weight percentage concentration of the carbon nanotubes is, the higher the viscosity of the carbon nanotube electric heating glue is, so that the carbon nanotube electric heating glue can be bonded with other objects. Referring to fig. 4, it is a temperature curve diagram of the electric tracing cement body when it is heated when the weight percentage concentration of the carbon nanotube is 4wt%, and the dotted line in the diagram indicates that the electric heating glue 3 of the carbon nanotube is stopped from supplying power from the time of the dotted line, and it can be shown from the diagram that when the weight percentage concentration of the carbon nanotube is 4wt%, the temperature decrease rate of the electric tracing cement body gradually tends to be slow and has a heat preservation effect, so that the energy can be effectively saved.
After the carbon nanotube electric heating paste 3 is manufactured, a first glass fiber 2 is taken down and placed on the surface of the first aluminum plate 1, the carbon nanotube electric heating paste 3 is taken up and coated on the surface of the first glass fiber 2. After coating, two conducting strips 7 are taken, two conducting strips 7 are respectively placed on two opposite sides of the first glass fiber 2, after placing, the carbon nanotube electric heating glue 3 is taken up and coated on the conducting strips 7, the shape of the conducting strips 7 is preferably T-shaped, when the carbon nanotube electric heating glue 3 is coated, the coating is only coated on the transverse side of the T-shaped straight side, and then the coating is not coated, so that each conducting strip 7 is formed to have an electric connection end exposed. Then, a second glass fiber 4 and a second aluminum plate 5 are sequentially stacked on the surface of the carbon nanotube electric heating glue 3, after being placed, a weight is placed on the surface of the second aluminum plate 5, the whole is allowed to stand for 24 hours, and after the whole is solidified, an electric heating composite material can be obtained.
Then, the electric heating composite material can be coated with cement to manufacture a cement floor or a cement outer wall, and a power supply unit 8 is required to be electrically connected with each electrical connection end in the process until the cement is solidified to form a cement body. Then, a control unit 9 is connected to the power supply unit 8 and a temperature sensor 0 for information, the temperature sensor 0 is disposed indoors for measuring the indoor temperature, and the temperature sensor 0 is also required to detect the surface temperature of the carbon nanotube electric heating glue 2 for subsequent temperature control.
Before controlling the temperature, the user must first set the temperature of the control unit 9 to obtain a temperature setting value, and then the control unitThe unit 9 controls the output current of the power supply unit 8 according to the sensing result of the temperature sensor 0 and the temperature setting value. For example, when the control unit 9 determines that the indoor temperature is lower than the temperature set value, the power supply unit 8 is controlled to increase the output current value, otherwise, the power supply unit 8 is controlled to stop outputting the current. In addition, in order to achieve a finer and more precise temperature control, the control unit 9 detects the indoor temperature and the surface temperature of the carbon nanotube electric heating glue 3 according to the temperature detector 0, and then according to the formula:
obtaining an output current value I, and controlling the output current of the power supply unit 8 to be the same as the output current value; wherein K is the heat transfer coefficient of the cement floor, A is the area of the cement floor, T 1 Is the temperature default value, T 2 The surface temperature of the carbon nanotube electrothermal glue, R is the resistance of the carbon nanotube electrothermal glue, and L is the thickness of the cement body.
When this creation is used for the cement outer wall, can the in-process that the cement body was makeed a cell body is made to the cement body 6 inside, the cell body is connected the electric heat combined material, the inside water that is equipped with of cell body. Therefore, when the electric heating composite material generates heat, the water in the tank body can be heated at the same time. A sprinkling unit is used for pumping out the water in the tank body and then sprinkling the water towards the outer side of the cement body 6, so that the ice and snow on the outer side of the cement body 6 can be effectively cleared, and the indoor temperature can be further kept.
In summary, the present invention utilizes the carbon nanotubes with better thermal conductivity, and the epoxy resin with the advantages of corrosion resistance, good plasticity, better electrical insulation effect, good thermal stability, etc. when the electrical heating composite material is made by combining the glass fibers and the aluminum plate, not only the electrical heating composite material has better thermal conductivity, but also the temperature is reduced slowly when the power supply is stopped, so as to have the thermal insulation effect, thereby effectively saving energy.
