Abstract
Description
Technical Field
[0001] This utility model relates to the field of new building materials technology, specifically to an insulation board with a composite elastic polymer coating. Background Technology
[0002] In simple terms, insulation boards are boards used for building insulation. They are rigid foam plastic boards made from polystyrene resin as the main raw material, along with other raw materials and polymers. This process involves heating and mixing while injecting a catalyst, followed by extrusion molding. These boards possess moisture-proof and waterproof properties, allowing for a reduction in the thickness of the building's external envelope, thus increasing usable indoor space. Existing insulation boards use a rigid coating of ordinary cement mortar for the outer plaster layer. This coating is prone to cracking and delamination due to thermal expansion and contraction, has poor waterproofing, and is susceptible to water seepage and cracking. Furthermore, on-site cement mortar plastering, substrate treatment, water-cement ratio, curing time, and many other factors can affect construction quality. Improper operation can easily lead to cracking and hollow areas. Construction also requires multiple steps, including dry-hanging the boards on the sides and applying alkali-resistant sealing primer, intermediate coat, and top coat, resulting in high costs. Therefore, an insulation board with a composite elastic polymer coating is designed to solve these problems. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this invention provides an insulation board with a composite elastic polymer coating. This solves the problems of existing insulation boards, which require side-hanging installation and multiple construction steps including spraying an alkali-resistant sealing primer, intermediate coat, and top coat, resulting in high costs. Furthermore, the outer plaster layer of existing insulation boards is a rigid coating applied with ordinary cement mortar, which is susceptible to cracking and detachment due to thermal expansion and contraction. It also exhibits poor waterproofing performance, easily leading to water seepage and cracking. Moreover, many factors during construction can affect the quality of the work.

[0022] 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.
[0023] Please see Figure 1-4 This utility model provides a technical solution: an insulation board with a composite elastic polymer coating, comprising: a wall 1, an insulation board body 2 arranged in an array on the front surface of the wall 1, a composite elastic polymer coating 3 fixedly connected to the front surface of the insulation board body 2, a mesh cloth 4 pre-embedded inside the composite elastic polymer coating 3, a plurality of pre-fabricated fixing holes 5 arranged in an array inside the insulation board body 2 and the composite elastic polymer coating 3, and holes also opened at positions opposite to the pre-fabricated fixing holes 5 in the wall 1, and expansion anchors 6 inserted and connected inside the pre-fabricated fixing holes 5 and the holes opened inside the wall 1.
[0024] In use, the insulation board body 2 is laid on a vibrating table, and a mold is installed. Elastic polymer mortar is poured into the mold, and the vibrating table is started to smooth the surface. After drying, the board is demolded to obtain a composite elastic polymer coated insulation board. Pre-drilled fixing holes 5 are made on the composite elastic polymer coated insulation board. During installation, the insulation board with the composite elastic polymer coating is laid on the wall. Fixing holes are drilled on the wall behind the pre-drilled fixing holes 5. Expansion anchors 6 are then inserted into the pre-drilled fixing holes 5 and extended into the fixing holes drilled on the wall. Finally, the expansion anchors are tightened. Installation can be completed with expansion anchors 6. The pre-fabricated composite elastic polymer coating 3 on the outer layer makes the insulation board body 2 less prone to problems caused by thermal expansion and contraction, and has good waterproof performance. The composite elastic polymer coating 3 fundamentally avoids the problems of cracking and hollowing caused by improper operation. The composite elastic polymer coating 3 improves adhesion and eliminates the need for a topcoat. The pre-fabricated fixing holes 5 on the front allow the board to be fixed with expansion anchors 6 on the front. The construction speed is fast, the cost is low, and the risk of the insulation board body 2 falling off is eliminated. At the same time, it reduces on-site construction procedures and lowers construction costs.
[0025] like Figure 1-4As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a stabilizing ring 21 is sleeved inside the prefabricated fixing hole 5. The front and rear ends of the stabilizing ring 21 extend to the outside of the insulation board body 2 and the composite elastic polymer coating 3.
[0026] Analysis of the above structure shows that when using expansion anchors 6 for fixing, the stabilizing ring 21 blocks the outside of the prefabricated fixing hole 5, which can reduce the deformation of the internal insulation board body 2, tighten the expansion anchors 6 more quickly, and strengthen the locking strength of the expansion anchors 6.
[0027] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, an expansion joint of 3mm to 5mm is provided between two adjacent insulation board bodies 2, and the expansion joint between the two adjacent insulation board bodies 2 is filled with silicone sealant.
[0028] Analysis of the above structure shows that silicone sealant has advantages such as bonding, sealing, leak prevention, and weatherproofing, and can strengthen the connection between adjacent insulation board bodies 2.
[0029] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the outer side of the insulation board body 2 extends outward, and the extension position of the insulation board body 2 is serrated.
[0030] Analysis of the above structure shows that when constructing large-area flat walls, using the insulation board body 2 with serrated edges allows potential cracks caused by expansion and contraction to form irregular shapes, thus optimizing the fixing effect of the mesh fabric and minimizing the risk of wall cracking.
[0031] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the outer side of the mesh cloth 4 extends to the outer side of the sawtooth position of the insulation board body 2, and the edges of adjacent mesh cloths 4 overlap each other.
[0032] Analysis of the above structure shows that in the connection area of the insulation board body 2, the laying and fixing of two layers of mesh cloth 4 and the pre-fabrication of mesh cloth 4 in the insulation board with composite elastic polymer coating can greatly enhance the tensile strength of the connection area. At the same time, in conjunction with the toothed edge design of the insulation board body 2, the risk of cracking at the joint is greatly reduced.
[0033] like Figure 1 As shown, this utility model embodiment provides an implementation method in which the outer side of the insulation board body 2 at the edge of the wall 1 is flat.
[0034] Analysis of the above structure shows that by laying the insulation board body 2 with straight edges on the outside, it is easy to install without trimming.
[0035] like Figure 1-4 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, the left and right sides of the serrated position of the insulation board body 2 are marked with different colors respectively.
[0036] Analysis of the above structure shows that during installation, it is only necessary to align the colors and lay them out, reducing the difficulty of installation.
