Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation boards, in particular to an energy-saving and environment-friendly polyurethane thermal insulation board. Background Art

[0002] With the advancement of building energy conservation, thermal insulation building materials have sprung up and flourished. Polyurethane insulation board has been widely used due to its excellent thermal insulation performance, simple preparation process, convenient processing and low production cost.

[0003] During installation, the polyurethane insulation board is first bonded to the building wall with an adhesive, and then a percussion drill is used to drill holes, and expansion screws are installed at the drilled holes for anchoring. However, the drilled holes on the surface of the insulation board are easily penetrated by rainwater, which reduces the insulation performance of the foam board and shortens the service life of the foam board.

[0004] Based on the above technical problems, the present application proposes an energy-saving and environment-friendly polyurethane insulation board. Utility Model Content

[0005] The purpose of the utility model is to provide an energy-saving and environment-friendly polyurethane insulation board to solve the technical problems mentioned in the background technology. The purpose of the utility model is achieved through the following technical solutions:

[0006] An energy-saving and environment-friendly polyurethane insulation board comprises an insulation board body made of polyurethane.

[0007] Furthermore, four side surfaces of the insulation board body are respectively provided with chamfered surfaces, and the chamfered surfaces are located on a side close to the rear surface of the insulation board body.

[0008] Furthermore, the depth of the blind hole is 1 / 2-2 / 3 of the thickness of the insulation board body, and the thickness of the plug is smaller than the depth of the blind hole.

[0009] Furthermore, a waterproof layer is provided on the side of the plug.

[0010] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0011] 1. By opening several blind holes on the front surface of the insulation board, drilling holes in the blind holes during installation, and plugging the blind holes with plugs after assembling the anchor rods, rainwater can be prevented from penetrating into the insulation board through the drilled holes, ensuring the insulation effect of the insulation board and extending the service life of the insulation board;

[0012] 2. By opening chamfered surfaces around the rear side of the insulation board, the amount of adhesive at the joints of adjacent insulation boards is increased, thereby improving the anti-seepage performance of the joints. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1-2 An energy-saving and environment-friendly polyurethane insulation board shown includes an insulation board body 1 and a plug 2. The insulation board body 1 is a rectangular plate made of polyurethane. Nine blind holes 11 are arranged in an array on the front surface of the insulation board body 1. Each blind hole 11 is detachably equipped with a plug 2 made of polyurethane. The number of blind holes 11 is related to the size of the insulation board body 1. The larger the size of the insulation board body 1, the more blind holes 11 there are. The depth of the blind hole 11 is 1 / 2-2 / 3 of the thickness of the insulation board body 1. The thickness of the plug 2 is less than the depth of the blind hole 11, thereby reserving a position for the pressure plate of the anchor rod 3.

[0019] When in use, the insulation board body 1 is first attached to the outer wall of the building by means of an adhesive, then a hole is drilled in the blind hole 11 by means of an impact drill, the anchor rod 3 is inserted into the drilled hole and locked, and finally the plug 2 is inserted into the blind hole 11 to achieve waterproof and anti-seepage of the insulation board body 1. A waterproof layer 21 is provided on the side of the plug 2, and the waterproof layer 21 can be a waterproof polyurethane coating.

[0020] As a preferred embodiment of the present application, the four sides of the insulation board body 1 are respectively provided with chamfered surfaces 12, and the chamfered surface 12 is located on the side close to the rear surface of the insulation board body 1. During installation, the adhesive on the edge of the insulation board body 1 is squeezed between the chamfered surfaces of two adjacent insulation board bodies 1, thereby improving the waterproof and anti-seepage performance of the splicing seam of the insulation board body 1.

[0021] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0022] 1. By opening several blind holes on the front surface of the insulation board, drilling holes in the blind holes during installation, and plugging the blind holes with plugs after assembling the anchor rods, rainwater can be prevented from penetrating into the insulation board through the drilled holes, ensuring the insulation effect of the insulation board and extending the service life of the insulation board;

[0023] 2. By opening chamfered surfaces around the rear side of the insulation board, the amount of adhesive at the joints of adjacent insulation boards is increased, thereby improving the anti-seepage performance of the joints.

[0024] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings.
