Referring to fig. 2, after the copper foils are laid in a staggered manner, the horizontal copper foils are parallel to each other, the vertical copper foils are parallel to each other, and the horizontal copper foils are perpendicular to the vertical copper foils. Two adjacent horizontal copper foils and two adjacent vertical copper foils are staggered to form a square copper foil unit, and the distance between two adjacent horizontal copper foils or between two adjacent vertical copper foils can be 1.5-2.5m, and is preferably 2 m.
The primer used for the antistatic primer layer 13 in the environment-friendly antistatic terrace 10 is antistatic paint. The raw materials of the antistatic paint comprise a first raw material and a second raw material, wherein the weight ratio of the first raw material to the second raw material is (20-40): 60-80. Specifically, the weight ratio of the first raw material to the second raw material may be 20: 80 or 30: 70 or 40: 60.
wherein, the first raw material can comprise the following components in a weight ratio of 60-80: 0.1-0.5: 5.1-10.5: 9-34.8 of waterborne epoxy curing agent, dispersant, conductive agent and deionized water.

The aqueous epoxy curing agent may be a PM-119 type amino-terminated epoxy curing agent available from Munjuga. The epoxy resin cured by the curing agent has high adhesive force and good coating performance and corrosion resistance.
Preferably, the amino-terminated epoxy curing agent has a solid content of 47-49%, a pH value of 6.5-7.5, and a viscosity of 1400-2100 MPa.S. In addition, the content of active hydrogen in the amine-based closed-end epoxy curing agent in the embodiment can be 20-25 wt%.

Preferably, the conductive carbon nanotubes are preferably single-walled carbon nanotube suspensions. In particular, the conductive carbon nanotubes can form a conductive 3D network between active material particles at very low concentrations, enhancing the electrode structure and improving the stability of the antistatic paint. In addition, the conductive carbon nanotubes can also improve the adhesion of the antistatic paint by combining with other particles contained in the antistatic paint, reducing the amount of binder.
When the conductive agent contains both conductive carbon black and conductive carbon nanotubes, the weight ratio of conductive carbon black to conductive carbon nanotubes may be, for example, 5 to 10: 0.1-0.5, such as 5: 0.1 or 10: 0.5 or 8: 0.3 or 5: 0.5 or 10: 0.1.
the first raw material takes deionized water as a dispersing solvent, and has the advantages of no odor, safety and environmental protection, so that the antistatic paint in the scheme is safe and environment-friendly, and no toxic substances are scattered.
The second feedstock may, for example, comprise a weight ratio of 70-90: 9.2-29.8: 0.2-0.8 of epoxy resin, reactive diluent and defoaming agent.

Preferably, the epoxy equivalent of the epoxy resin used in the present embodiment may be, for example, 182-192g/eq, and the epoxy percentage thereof may be, for example, 22.4-23.6%. The liquid epoxy resin and the amino closed-end epoxy curing agent in the first raw material are subjected to curing reaction under the parameters, so that the anti-static paint has high hardness, high pressure resistance and high wear resistance.
The reactive diluent is preferably a water soluble diluent comprising 1, 4-butanediol diglycidyl ether. By adding the reactive diluent into the second raw material, the paint can play a good role in wetting other first raw materials and the second raw materials, and improves the permeability of the epoxy resin, thereby improving the hardness of the antistatic paint.
Alternatively, the water-soluble diluent in this embodiment may be 1, 4-butanediol diglycidyl ether of Murraya corporation, model PM-116.

As can be seen from table 1, the environmental protection antistatic terrace obtained in the embodiments 1 to 4 has better performance in impact resistance, hardness and antistatic ability than the common terrace sold in the market, which indicates that the antistatic paint of the embodiments of the present invention can improve the antistatic ability of the environmental protection antistatic terrace. Compared with the embodiments 1 to 4, it can be seen that the pencil hardness and the antistatic ability of the environment-friendly antistatic terrace of the embodiments 2 to 4 are better than those of the environment-friendly antistatic terrace of the embodiment 1, and it is demonstrated that the copper foil layer and the conductive agent which simultaneously comprise conductive carbon black and conductive carbon nanotubes are arranged between the concrete bottom layer and the antistatic primer layer, so that the hardness and the antistatic ability of the environment-friendly antistatic terrace can be properly improved. The hardness and the anti-static capability of the environment-friendly anti-static floor in the embodiment 4 are optimal, which shows that each layer of the environment-friendly anti-static floor in the embodiment has reasonable structure and the anti-static primer has optimal component ratio.

Comparison of the Performance test method in test example 1Groups 1-4 were tested.
The test results show that the overall performance of the environment-friendly antistatic terrace of the control group 1-4 is worse than that of the embodiment 4, and mainly reflects on the aspects of adhesive force and antistatic capability. In addition, the environmental-friendly anti-static terrace of the comparison group 3-4 has larger surface resistance difference at different positions, which shows that the rheological property of the anti-static paint is too small or too large due to the too large or too small specific surface area of the nano fumed silica, so that the anti-static paint is not uniform in the environmental-friendly anti-static terrace, and the surface resistance difference at different positions is large.
Further, examples 1 to 3 were each subjected to the tests of test examples 1 to 4 in place of example 4, and the test results thereof were in agreement with the results obtained in example 4.
