Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane foam boards, in particular to a modified polyurethane foam board. Background Art

[0002] Modified polyurethane foam is a polymer formed by mixing isocyanate and polyether as the main raw materials, and foaming through special equipment under the action of various additives such as foaming agent, catalyst, flame retardant, etc. Modified polyurethane foam board is mainly used in building exterior wall insulation and cold storage insulation materials.

[0003] The existing insulation board has a simple structure. When the foam boards are pasted together, the joints between the foam boards are not properly handled and are easily penetrated by rainwater, which reduces the insulation performance of the foam boards and shortens the service life of the foam boards.

[0004] Based on the above technical problems, the present application proposes a modified polyurethane foam board. Utility Model Content

[0008] Furthermore, slots and inserts are respectively provided on the left and right sides of the foam board body.

[0009] Furthermore, a plurality of insertion holes are provided on the step, and plugs corresponding to the insertion holes are fixed on the sealing strip.

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

[0011] 1. By setting steps on the upper and lower edges of the foam board body and adhering sealing strips on the steps, the waterproof performance of the joints between the foam board bodies is improved, thereby improving the thermal insulation performance and service life of the foam board;

[0012] 2. The connection between the two foam board bodies is achieved by plugging the pin on the sealing strip into the sockets on the two foam board bodies, thereby improving the connection strength between the foam board bodies, reducing the use of bolts, and improving the convenience of installation.

[0018] 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.

[0019] like Figure 1-Figure 3 A modified polyurethane foam board is shown, comprising a foam board body 1 and a sealing strip 2, both of which are made of modified polyurethane. The foam board body 1 is a rectangular board, and steps 11 are respectively provided at the upper and lower edges of the front side wall of the foam board body 1, and a slope 12 with an inclination angle of 45° is provided between the step 11 and the front side wall of the foam board body 1. The thickness of the step 11 is 1 / 2-2 / 3 of the foam board body.

[0020] like Figure 1-Figure 3 As shown, the sealing strip 2 is a long strip structure with an isosceles trapezoidal cross section, and a plurality of foam board bodies 1 are arranged in an array, and the sealing strip 2 is filled between the upper and lower connecting seams of two adjacent foam board bodies 1. By setting steps at the upper and lower edges of the foam board bodies and adhering the sealing strip at the steps, the waterproof performance of the joints between the foam board bodies is improved, rainwater is prevented from entering the gap between the foam board bodies and the wall, and the thermal insulation performance and service life of the foam board are improved.

[0021] like Figure 1 As shown, as a preferred embodiment of the present application, a plug strip 13 is vertically fixed on the left side of the foam board body 1, and a slot 14 matching the plug strip 13 is vertically opened on the right side of the foam board body 1, and the upper and lower ends of the plug strip 13 and the slot 14 respectively penetrate the upper and lower surfaces of the foam board body 1. When in use, the left and right plug-in of the foam board body 1 is achieved through the plug strip 13 and the slot 14, which can improve the anti-seepage performance of the left and right gaps on the one hand, and reduce the difficulty of installation on the other hand.

[0022] like Figure 1 , Figure 2 As shown, three insertion holes 15 are opened on the slope 12 of the foam board body 1, and six plugs 21 corresponding to the positions of the insertion holes 15 are fixed on the inner side of the sealing strip 2. When in use, an adhesive is applied to the inner side of the sealing strip 2, and then the plugs 21 are inserted into the insertion holes 15, so that the connection between the two foam board bodies 1 is realized, the connection strength between the foam board bodies 1 is improved, the use of bolts is reduced, and the convenience of installation is improved. The reduction of bolts also reduces the number of holes opened on the foam board body 1, further improving the anti-seepage performance of the foam board.

[0023] 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.
