Description

Technical Field

[0001] The utility model relates to the technical field of anti-static flooring, in particular to a polyurethane anti-static floor paint. Background Art

[0002] Polyurethane mortar flooring, typically a water-based polyurethane mortar, possesses nearly all the advantages of both organic polymers and inorganic concrete, including anti-slip properties, resistance to high and low temperatures, mechanical loads and impacts, resistance to harsh chemicals, antibacterial and mildew-resistant properties, low VOCs, and environmental friendliness. However, polyurethane mortar products offer limited or no anti-static properties. Furthermore, polyurethane mortar flooring is susceptible to changes after curing.

[0003] The utility model with publication number CN209099710U proposes a polyurethane mortar anti-static floor. Above the base layer, from bottom to top, it includes a polyurethane mortar batch coating bottom layer, a polyurethane mortar trowel coating middle layer, a copper foil layer, and a polyurethane mortar anti-static self-leveling layer. The copper foil layer is formed by vertically and cross-laying copper foil strips with a width of 8 to 12 mm. The base layer is provided with anchoring grooves. The polyurethane mortar anti-static floor described in this utility model uses a self-leveling method to apply a polyurethane mortar anti-static layer to the polyurethane mortar surface. The copper foil layer forms a grounding strip, giving the floor a permanent anti-static function, a smooth surface, and a highly decorative effect. It is particularly suitable for operating rooms, IC manufacturing, IC-related whole machine assembly factories, flammable and explosive environments, and cleanrooms.

[0004] However, the above-mentioned existing technology still has the following deficiencies when used: the base layer, the polyurethane mortar batch coating bottom layer and the polyurethane mortar trowel coating middle layer are prone to dislocation and then falling off after molding. Analysis shows that the base layer, the polyurethane mortar batch coating bottom layer and the polyurethane mortar trowel coating middle layer have the problem of insufficient adhesion strength. Although an anchor groove is opened on the base layer, the polyurethane mortar batch coating bottom layer will form settlement in the anchor groove after laying, but this reinforcement method is less effective.

[0005] To this end, the utility model provides a polyurethane antistatic floor paint. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polyurethane anti-static floor paint to solve the problems raised in the above background technology. The utility model has the function of improving the connection strength of the base layer, the polyurethane mortar batch coating bottom layer and the polyurethane mortar trowel coating middle layer, enhancing the adhesion between the two adjacent layers of the three layers, and greatly extending the service life.

[0007] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a polyurethane anti-static floor paint, including a floor paint layer, a base layer, a polyurethane mortar batch coating bottom layer located above the base layer, and a polyurethane mortar trowel coating middle layer located above the polyurethane mortar batch coating bottom layer is provided at the bottom of the floor paint layer, and an anti-dislocation structure with a dot matrix arrangement is provided between the base layer, the polyurethane mortar batch coating bottom layer and the polyurethane mortar trowel coating middle layer, the anti-dislocation structure includes a pile body, connecting bolts and a connecting rod, the outer peripheral wall of the pile body is fixedly connected with at least two circumferentially evenly distributed support plates close to the bottom, the top of the support plate is fixedly connected with a support plate for supporting the connecting rod, the adjacent anti-dislocation structures are connected by a connecting rod, the pile body is sleeved with an elastic pressure ring used in conjunction with the connecting rod, and the middle part of the pile body is penetrated by a connecting hole adapted for the connecting bolt.

[0008] Furthermore, the number of the supporting plates is four and a plurality of supporting legs arranged along the length direction are fixedly provided on the bottom of the supporting plates.

[0009] Furthermore, a pad is welded to the bottom of the leg.

The annular pressure plate is located below the retaining ring and is fixedly connected to the retaining ring through the connecting spring.

[0011] Furthermore, a slot adapted to the connecting rod is provided on the top of the support plate.

[0012] Furthermore, the number of the support plates is at least two and they are arranged along the length direction of the support plate.

[0013] Furthermore, the outer peripheral wall of the connecting rod is fixedly welded with reinforcement protrusions that are evenly distributed in the axial direction.

[0014] The beneficial effects of the utility model are as follows:

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a polyurethane antistatic floor paint, including a floor paint layer, a base layer 1, a polyurethane mortar batch coating bottom layer 2 located above the base layer 1, and a polyurethane mortar trowel coating middle layer 3 located above the polyurethane mortar batch coating bottom layer 2. The other structures of the floor paint layer adopt the structures in the patent literature mentioned in the background technology. The technical solution is an improvement on the insufficient adhesion strength of the floor layer in the existing technology.

[0023] In this technical solution, an anti-dislocation structure 5 with a dot matrix arrangement is provided between the base layer 1, the polyurethane mortar batch coating bottom layer 2 and the polyurethane mortar trowel coating middle layer 3. The function of the anti-dislocation structure 5 is to improve the strength of dislocation after the base layer 1, the polyurethane mortar batch coating bottom layer 2 and the polyurethane mortar trowel coating middle layer 3 are adjacently attached, which can effectively avoid cracking and improve the density of the floor layer after curing.

[0024] Specifically, the anti-dislocation structure 5 includes a pile body 51, a connecting bolt 52 and a connecting rod 53. The outer peripheral wall of the pile body 51 is fixedly connected with at least two circumferentially evenly distributed supporting plates 511 close to the bottom. When in use, the supporting plates 511 are placed on the base layer 1. The function of the supporting plates 511 is to keep the pile body 51 in a stable vertical state. The top of the supporting plate 511 is fixedly connected with a support plate 5111 for supporting the connecting rod 53. Adjacent anti-dislocation structures 5 are connected by the connecting rod 53, that is, the connecting rod 53 plays the role of connecting adjacent anti-dislocation structures 5. When in use, the connecting rod 53 is located in the polyurethane mortar batch coating bottom layer 2, thereby improving the strength of the entire polyurethane mortar batch coating bottom layer 2 after molding. The top of the pile body 51 extends into the polyurethane mortar trowel coating middle layer 3, and the anti-dislocation reinforcement of this layer after molding is performed.

[0025] Furthermore, an elastic pressure ring 512 is provided on the pile body 51 for use with the connecting rod 53. That is to say, when laying the connecting rod 53, the connecting rod 53 is placed on the support plate 5111 and then tightened with the elastic pressure ring 512 so that the connecting rod 53 will not fall off easily. This arrangement facilitates the improvement of the construction progress of the polyurethane mortar batch coating base layer 2, and the installation method of the connecting rod 53 also greatly improves the efficiency of the installation of the anti-dislocation structure 5.

[0026] In this technical solution, a connecting hole 514 adapted to the connecting bolt 52 is opened through the middle of the pile body 51. During implementation, an anchor bolt hole can be opened on the top of the base layer 1, and then a pre-embedded connecting sleeve is installed in the anchor bolt hole. The connecting bolt 52 squeezes and fixes the pile body 51 on the base layer 1 through the pre-embedded connecting sleeve. As a result, the base layer 1, the polyurethane mortar batch coating bottom layer 2 and the polyurethane mortar trowel coating middle layer 3 are in a fastened connection state, which greatly improves the adhesion strength of the base layer 1, the polyurethane mortar batch coating bottom layer 2 and the polyurethane mortar trowel coating middle layer 3 after forming.

[0027] In this embodiment, there are four support plates 511 and a plurality of legs 5112 arranged along the length direction are fixedly provided at the bottom thereof, wherein a pad 51121 is welded to the bottom of the leg 5112. The function of the leg 5112 is to raise the support plate 511 so that the polyurethane mortar coating base layer 2 can densely fill the gap around the pile body 51. In addition, this arrangement enables a plurality of anti-dislocation structures 5 to form a grid structure after installation, thereby further improving the strength of the polyurethane mortar coating base layer 2 after forming.

[0028] In this embodiment, a retaining ring 513 is provided on the top of the pile body 51, and the elastic pressure ring 512 includes a connecting spring 5121 and an annular pressure plate 5122. The annular pressure plate 5122 is located below the retaining ring 513 and is fixedly connected to the retaining ring 513 through the connecting spring 5121. When the annular pressure plate 5122 is pushed upward, the connecting spring 5121 will be compressed. When in use, the annular pressure plate 5122 uses the extrusion force of the connecting spring 5121 to squeeze the connecting rod 53 onto the support plate 5111, thereby improving the stability of the connecting rod 53 after being placed on the support plate 5111.

[0029] Furthermore, a slot 51111 is formed on the top of the support plate 5111 to fit the connecting rod 53. The slot 51111 further limits the connecting rod 53 and prevents the connecting rod 53 from being separated from the support plate 5111 when subjected to a large lateral force. There are at least two support plates 5111, which are arranged along the length of the support plate 511. This arrangement can improve the stability of the connection between the connecting rod 53 and the support plates 5111.

[0030] In this embodiment, the outer peripheral wall of the connecting rod 53 is fixedly welded with axially evenly distributed reinforcement protrusions 531. This arrangement can improve the strength of the attachment connection between the connecting rod 53 and the polyurethane mortar batch coating bottom layer 2.

[0031] Working principle:

[0032] During use, first, the embedded anchor bolt holes are processed on the surface of the base layer 1, and then the pile body 51 is fastened and installed on the base layer 1 by connecting the connecting bolts 52 and the embedded anchor bolt holes. Then, the connecting rod 53 is placed on the support plate 5111 on the adjacent pile body 51, and is pressed tightly using the annular pressure plate 5122. Then, the polyurethane mortar batch coating base layer 2 is injected above the base layer 1, so that the polyurethane mortar batch coating base layer 2 submerges the connecting rod 53, and ensure that the top of the pile body 51 is higher than the surface layer of the polyurethane mortar batch coating base layer 2. Then, the polyurethane mortar trowel coating middle layer 3 is injected into the surface layer of the cured polyurethane mortar batch coating base layer 2. After the polyurethane mortar trowel coating middle layer 3 is cured, the adhesion strength of the base layer 1, the polyurethane mortar batch coating base layer 2 and the polyurethane mortar trowel coating middle layer 3 after formation will be greatly enhanced.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
