Embodiment 1

[0019] Embodiment 1: a kind of solar panel coating, it comprises: step 1, spray resin base layer; Step 2, heat preservation treatment; Step 3, spray heat-absorbing layer; Step 4, dry; Step 5, spray cured layer; Step 6 , Finished product.

[0020] Step 1. Spray the resin base layer: clean the surface of the solar collector plate, and then use a spraying machine to spray a 0.05-0.15mm thick resin base layer on the surface of the heat collector plate;

[0021] Step 2. Heat preservation treatment: place the heat collecting plate after spraying in the heat preservation workshop, with the sprayed surface of the heat collection plate facing up, and place it horizontally.

[0022] Step 3. Spray the heat-absorbing layer: Use a spraying machine to spray a 0.2-0.55mm thick heat-absorbing layer on the resin base of the heat collecting plate. The spraying is divided into multiple times. After spraying once, let it stand for 30-60 minutes, and then again For spraying, the total number of s...

Embodiment 2

[0032] Embodiment 2: a kind of solar panel coating, it comprises: step 1, spray resin base layer; Step 2, heat preservation treatment; Step 3, spray heat-absorbing layer; Step 4, dry; Step 5, spray cured layer; Step 6 , Finished product.

[0033] Step 1. Spray the resin base layer: clean the surface of the solar collector plate, and then use a spraying machine to spray a 0.15mm thick resin base layer on the surface of the heat collector plate;

[0034] Step 2. Insulation treatment: place the heat collecting plate after spraying in the heat preservation workshop, with the sprayed surface of the heat collection plate facing up, and place it horizontally. The temperature in the heat preservation workshop is 80°C, keep it warm for 5 hours, and then take it out and cool it to room temperature;

[0035] Step 3. Spray heat-absorbing layer: Use a spraying machine to spray a 0.55mm thick heat-absorbing layer on the resin base layer of the heat collecting plate. The spraying is divided ...

Embodiment 3

[0039] Example 3: The heating comparison between the present application and the prior art, the experimental group is Example 2, the control group 1 is vacuum tube solar energy, and the control group 2 is the prior art heat-absorbing plate solar energy, the test is the same day, no shading, heat absorption The plate area is equal, see Table 1.

[0040] Table 1

[0041] half day temperature temperature throughout the day test group 55℃ 69℃ Control group 1 49℃ 58℃ Control group 2 54℃ 67℃

[0042] Conclusion: From Table 1, it can be seen that the coating of this application is significantly better than the traditional vacuum tube type solar energy, and the heat absorbing plate type with the same structure, due to the difference in coating, the half-day temperature difference is 1 degree, and the whole day temperature difference is 2 degrees.

[0043] The invention has a reasonable structure and is easy to use. The heat absorbing layer adopts...

Abstract

The invention discloses a solar panel coating. The solar panel coating method comprises the following steps that step 1, a resin base layer is sprayed; step 2, heat preservation treatment is carried out; step 3, a heat absorption layer is sprayed; step 4, drying is carried out; step 5, a curing layer is sprayed; and step 6, a finished product is obtained. The heat absorption layer is made of graphene or a mixture of graphene and carbon powder, the heat absorption efficiency is maximized, and the technical problems that a solar panel in the prior art is poor in heat absorption effect and inconvenient to use are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of solar panels, and in particular relates to a solar panel coating. Background technique [0002] The solar energy is provided with an upper water collection pipe, a lower water collection pipe, and several heat collecting plates arranged vertically. When working, the heat collecting plate is placed obliquely in the open air to receive sunlight, absorb solar radiation energy and perform light-to-heat conversion. After the heat collecting plate conducts and heats the internal water or medium, hot water circulates in the pipe cavity of the heat collecting plate Ascent, it flows out from the outlet pipe above the heat collecting plate, and the water inlet pipe is continuously replenished with cold water to continue to circulate and flow in the discharge pipe cavity of the heat collecting plate for heating. [0003] The heat collecting plate is made of metal, and the surface is equipped with a heat-absorbing c...
