However, the following drawbacks remain: while magnetic connection methods are widely used in industrial and residential applications due to their ease of installation, ensuring that the magnetic structure meets the requirements for rapid installation, possesses sufficient connection strength, and avoids interfering with the static electricity conduction path remains a technical challenge in the field of antistatic flooring. Utility Model Content

[0004] The purpose of this invention is to provide a calcium sulfate-based magnetic quick-installation antistatic floor to solve the problems mentioned in the background art.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 This utility model provides a calcium sulfate-based magnetic quick-installation antistatic floor. The floor includes: a calcium sulfate substrate 1, with a first conductive layer and a second conductive layer respectively provided on the upper and lower surfaces of the calcium sulfate substrate 1; a conductive adhesive strip 2, which is disposed on the outer side of the calcium sulfate substrate 1; multiple sets of magnetic assemblies, each magnetic assembly including a permanent magnet 5 embedded in an indentation 10 opened at the edge of the calcium sulfate substrate 1, the permanent magnet 5 forming a magnetic connection with an iron bracket for floor installation; and an elastic buffer structure disposed on the polygonal outer side of the calcium sulfate substrate 1 and in contact with the iron bracket for floor installation.

[0031] In this invention, the calcium sulfate substrate 1 is formed by mixing and pressing anhydrous calcium sulfate, reinforcing fibers and additives, the first conductive layer is aluminum foil, and the second conductive layer is an antistatic coating.

[0032] Specifically, both the aluminum foil and the antistatic coating are in contact with the conductive strip 2, and the conductive strip 2 is in contact with the iron bracket used for floor installation to conduct electricity, forming an all-round conductive network, which effectively improves the antistatic effect of the floor.

[0033] In this invention, the calcium sulfate substrate 1 has snap-fit ​​grooves 9 at its four corners, and the conductive adhesive strip 2 is snapped into the snap-fit ​​grooves 9 and wraps around the edges of the calcium sulfate substrate 1.

[0034] Specifically, by setting the snap-fit ​​groove 9, the conductive adhesive strip 2 is effectively connected and fixed to the calcium sulfate substrate 1. Due to the snap-fit ​​structure, the conductive adhesive strip 2 is also effectively prevented from warping.

[0035] In this utility model, chamfered angles 8 are provided at the bottom corners of all four sides of the conductive adhesive strip 2.

[0036] Specifically, the chamfered angle 8 is designed to make it easier for the floor and conductive adhesive strip 2 to be squeezed into the iron bracket used for floor installation during installation.

[0037] In this invention, the surface of the permanent magnet 5 is provided with a conductive coating 11 that contacts the conductive strip 2. The conductive coating 11 is a silver plating layer, and the permanent magnet 5 is a neodymium iron boron magnet.

[0038] Specifically, the permanent magnet 5 facilitates the quick magnetic adhesion between the floor and the iron support. At the same time, by setting a silver plating layer on the outside of the permanent magnet 5 and having the silver plating layer in contact with the conductive strip 2, the magnetic attraction can be maintained, and static electricity can be directly discharged through the silver plating layer and the conductive strip 2. This effectively avoids the problem of the permanent magnet 5 interfering with the static electricity conduction path due to the permanent magnet 5 being placed at the position of the conductive strip 2.

[0039] In this utility model, the elastic buffer structure includes a side groove 6 formed on the outer periphery of the calcium sulfate substrate 1. A buffer pad 7 is bonded in the side groove 6. The cross-section of the buffer pad 7 is oval. The buffer pad 7 is made of elastic rubber. The width of the buffer pad 7 is greater than the gap between the floor and the iron bracket used for installation. The elastic rubber fills the gap after being squeezed.

[0040] Specifically, since the width of the elastic rubber is greater than the gap between the floor and the iron bracket used for installation, the elastic rubber can fill the gap after being squeezed, effectively preventing the gap between the floor and the iron bracket from being easily displaced due to vibration or uneven load, affecting the flatness and anti-static performance. Furthermore, since the cross-section of the elastic rubber is oval, it is easier for the floor and the elastic rubber to be embedded into the iron bracket.

[0041] In this invention, the bottom of the calcium sulfate substrate 1 is provided with multiple dent-shaped structures 3 and supporting ribs 4, and the supporting ribs 4 and the dent-shaped structures 3 are distributed alternately to form a strength support network.

[0042] Specifically, the trough structure 3 achieves uniform load distribution through geometric continuity. Each trough structure 3 converts vertical load into circumferential stress through the curved panel shell effect. Combined with the spatial truss system formed by the supporting ribs 4, the local stress is attenuated by more than 60% within the effective range. The supporting ribs 4 adopt a bidirectional cross layout to form a strength support network with the trough structure 3, which maintains the continuity of the stress transmission path and avoids stress concentration at rigid connection nodes.

[0043] Flooring preparation:

[0044] 1. Preparation process: Anhydrous calcium sulfate, reinforcing fiber, additives and water are mixed and stirred evenly, and then injected into a lower mold with a trough structure 3, a support rib 4 with an inner groove 10 and a side groove 6, and an upper mold with a snap-fit ​​groove 9. The mold is cold-pressed and formed under a pressure of 10-15MPa. After demolding, the mold is dried at 60-80℃ until the moisture content is ≤5%.

[0045] First conductive layer: A 0.03-0.05mm thick metal foil layer is adhered and firmly bonded to the upper surface of the calcium sulfate substrate 1 with conductive adhesive.

[0046] Second conductive layer: An antistatic coating with a thickness of 0.05-0.1 mm is formed by spraying an aqueous carbon-based conductive coating onto the lower surface of the calcium sulfate substrate 1 and drying it.

[0047] The conductive adhesive strip 2 is inserted into the snap-fit ​​groove 9 of the calcium sulfate substrate 1 and wraps around the calcium sulfate substrate 1.

[0048] 2. Magnetic assembly installation:

[0049] A silver plating layer is applied to the exterior of the permanent magnet 5.

[0050] Confirm the position of the embedded groove 10 formed after the calcium sulfate substrate 1 is formed.

[0051] The permanent magnet 5 is embedded into the inner groove 10 and fixed with epoxy resin adhesive.

[0053] 3. Installation of elastic buffer structure:

[0054] Confirm the position of the side groove 6 formed after the calcium sulfate substrate 1 is formed.

[0055] The elastic rubber is embedded into the side groove 6 and fixed with epoxy resin.

[0056] Floor installation:

[0057] Ground pretreatment, ground leveling, cleaning the ground and laying a moisture-proof membrane.

[0058] For the installation of iron brackets, the installation position of the iron brackets is determined according to the room size and floor specifications. Horizontal and vertical joists are installed, and the iron brackets are connected into a grid structure by bolts or clips.

[0059] For floor installation, insert the floorboard into the grid structure of the iron support, and gently press to make the permanent magnet 5 attract and connect with the iron support, and then squeeze the elastic rubber to fill the gap between the floorboard and the iron support.

[0060] Lay the subsequent floorboards in sequence, gently tapping the edges of the floorboards with a rubber mallet to ensure a tight magnetic connection.
