AI Technical Summary
市面上的保温装饰板由装饰面、保温材料复合制成，虽然装饰面具有一定的防水功能，但保温材料一般都不具备防水功能，因此只能形成一个单面防水的结构，而且在应用中保温装饰板一般采用砂浆粘接和锚固件固定的方式安装在墙体基层上，即在保温板背离装饰面的一侧采用砂浆与基层直接粘接的方式，该方式的粘接强度主要取决于砂浆与保温板或背板之间的粘接强度，由于保温材料或背板会带走砂浆内部水分，导致砂浆强度下降，而且墙体本身无防水构造，室内外温差形成的水汽会积聚在保温装饰板内部，增加保温装饰板掉落和饰面层脱落的风险；采用砂浆粘贴的方式时与各类防水材料的粘接不稳定会导致施工初期强度无法保证，且施工周期较长
[0015]通过以上设计，在防水面板层内外层都设置防水层进行防水封闭，提升了防水面板层使用寿命；在防水面板层的外侧还设置了装饰涂层、在防水面板层和保温层之间采用高强度树脂粘接层粘接进一步提升了其防水性，从而保证了外部水分无法渗透到保温层，提升了保温层的寿命；自粘防水层既能有效防止墙体中的水分进入保温层，提升了保温性能和保温层的寿命，也避免保温层大量吸水增加自重降低整体稳定性；自粘防水层的高强度自粘特性使其在保温层与墙体基层间粘结，无需额外进行砂浆粘接，其耐久性高于砂浆，施工效率也大大提升。

Abstract
Description
Technical Field
[0001] This application relates to insulation boards, and more particularly to a self-adhesive waterproof and thermal insulation composite board. Background Technology
[0002] Thermal insulation decorative panels are widely used in exterior wall insulation. Commercially available thermal insulation decorative panels are composites of decorative and insulation materials. While the decorative surface offers some waterproofing, the insulation material generally lacks this feature, resulting in a single-sided waterproof structure. Furthermore, in practice, these panels are typically installed on the wall substrate using mortar bonding and anchoring. This involves directly bonding the insulation panel to the substrate with mortar on the side facing away from the decorative surface. The bonding strength in this method depends primarily on the bond between the mortar and the insulation panel or backing plate. Since the insulation material or backing plate can draw moisture from the mortar, its strength decreases. Moreover, the wall itself lacks a waterproof structure, allowing moisture from temperature differences between indoors and outdoors to accumulate inside the insulation panel, increasing the risk of panel detachment and surface layer peeling. The unstable bonding with various waterproofing materials using mortar bonding also leads to insufficient initial strength during construction and a longer construction period. Summary of the Invention
[0003] In view of this, this application provides a self-adhesive waterproof and thermal insulation composite board. By setting a waterproof panel layer and a self-adhesive waterproof layer on both sides of the thermal insulation board, the bonding stability of the board itself is improved, and the waterproof performance of the thermal insulation composite board is enhanced. This not only simplifies the construction process and improves construction efficiency, but also greatly extends the service life of the thermal insulation composite board and avoids the risk of the thermal insulation composite board falling off and the panel layer peeling off later.
[0004] To achieve the above objectives, this application employs the following technical solution:
[0005] A self-adhesive waterproof and thermal insulation composite board is characterized in that it comprises a waterproof panel layer, a thermal insulation layer and a self-adhesive waterproof layer connected sequentially from the outside to the inside. The waterproof panel layer consists of a middle board layer, an outer waterproof layer coated on the outer surface of the board layer and an inner waterproof layer coated on the inner surface of the board layer. The waterproof panel layer and the thermal insulation layer are bonded together by a high-strength resin adhesive layer. The side of the self-adhesive waterproof layer away from the thermal insulation layer is used to bond to the wall substrate.
[0006] The thickness of the waterproof panel layer is 6-10mm, the thickness of the thermal insulation layer is 20mm or more, and the thickness of the self-adhesive waterproof layer is 2-5mm.
[0007] The middle layer of the waterproof panel is a calcium silicate board layer or a metal board layer.
[0008] The outer waterproof layer of the waterproof panel is an epoxy resin layer or a UV-cured resin layer.
[0009] The inner waterproof layer of the waterproof panel layer is any one of epoxy resin layer, UV resin layer, synthetic emulsion layer or polymer waterproof coating layer.
[0010] The insulation layer is any one of the following: polystyrene foam board layer, polystyrene-based modified board layer, rock wool layer, glass wool layer, foamed ceramic layer, foamed glass layer, or vacuum insulation board layer.
[0011] Before being bonded to the wall substrate, the self-adhesive waterproof layer has a peelable protective layer on the side used for bonding to the wall substrate.
[0012] The waterproof panel layer is further coated with a decorative coating on the outer surface of its outer waterproof layer; the high-strength resin adhesive layer is an epoxy resin adhesive layer or a polyurethane adhesive layer.
[0013] The self-adhesive waterproof layer is an asphalt self-adhesive waterproof layer with asphalt as the main component.
[0014] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:
[0015] Through the above design, waterproof layers are installed on both the inner and outer layers of the waterproof panel for waterproof sealing, thus extending the service life of the waterproof panel layer. A decorative coating is also applied to the outside of the waterproof panel layer, and a high-strength resin adhesive layer is used to bond the waterproof panel layer and the insulation layer, further enhancing its waterproofness. This ensures that external moisture cannot penetrate into the insulation layer, extending its lifespan. The self-adhesive waterproof layer effectively prevents moisture from the wall from entering the insulation layer, improving insulation performance and extending the insulation layer's lifespan. It also avoids the insulation layer absorbing excessive water, increasing its weight and reducing overall stability. The high-strength self-adhesive properties of the self-adhesive waterproof layer allow it to bond between the insulation layer and the wall substrate without the need for additional mortar bonding. Its durability is higher than that of mortar, and construction efficiency is greatly improved.
[0016] In some embodiments, a backing layer is provided between the insulation material layer and the self-adhesive waterproof layer. The insulation layer and one side of the backing layer are bonded together by a high-strength resin adhesive layer, and the other side of the backing layer is directly bonded to the self-adhesive waterproof layer.
[0017] In some embodiments, a connecting reinforcement layer is further provided between the thermal insulation layer and the self-adhesive waterproof layer. The connecting reinforcement layer is made of fiber mesh fabric and is sandwiched between the thermal insulation layer and the self-adhesive waterproof layer through the bonding between the self-adhesive waterproof layer and the thermal insulation layer.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.
[0024] like Figure 1 As shown, the self-adhesive waterproof and thermal insulation composite board of this application includes a waterproof panel layer 1, a thermal insulation layer 2, and a self-adhesive waterproof layer 4 connected sequentially from the outside to the inside. A high-strength resin adhesive layer 5 is used to bond the waterproof panel layer 1 and the thermal insulation layer 2. This high-strength resin adhesive layer 5 can be either an epoxy resin adhesive layer or a polyurethane adhesive layer. A decorative coating 6 is also present on the outside of the waterproof panel layer 1. This decorative coating 6 can be a water-based or oil-based paint layer. Besides enhancing the aesthetics, this layer also improves the waterproof performance of the outside of the waterproof panel layer 1. The self-adhesive waterproof and thermal insulation composite board of this invention also has a protective layer 41 on the outside of the self-adhesive waterproof layer 4 at the time of manufacture, such as... Figure 3 and Figure 4 When using it, peel off the protective layer 41 to bond the self-adhesive waterproof layer 4 to the wall base 7, and the self-adhesive waterproof and heat-insulating composite board can be attached to the wall base 7.
[0025] like Figure 2 The waterproof panel layer 1 shown includes an outer waterproof layer 11, an inner waterproof layer 12, and a middle board layer 13. The board layer 13 is a calcium silicate layer or a metal plate layer with a thickness of 6-10mm. The outer waterproof layer 11 is sealed with an epoxy resin layer or a UV-cured resin layer to effectively prevent external moisture from entering the insulation layer 2. The inner waterproof layer 12 of the waterproof panel layer 1 is sealed with any one of an epoxy resin layer, a UV resin layer, a synthetic emulsion layer, or a polymer waterproof coating layer. By applying double-layer waterproof treatment to the inner and outer sides of the waterproof panel layer 1, the waterproof panel layer 1 and the insulation layer 2 can be effectively protected, thus improving the overall service life of the board.
[0026] Insulation layer 2 can be any of the following: polystyrene foam board layer, modified board layer with polystyrene as the base material, rock wool or glass wool layer, foamed ceramic layer, foamed glass layer, or vacuum insulation board layer. A fireproof and soundproof material layer can also be added to improve its fireproof and soundproof performance. The thickness of insulation layer 2 is set according to geographical location and actual needs, with a minimum of 20mm. In northern regions or where higher insulation performance is required, its thickness can be significantly increased to effectively improve insulation performance.
[0027] The self-adhesive waterproof layer 4 is an asphalt self-adhesive waterproof layer with asphalt as the main component, and its thickness is 2-5mm. This asphalt self-adhesive waterproof layer can be prepared using the following materials: base asphalt: 55-60%, filler: 15-20%, modified SBS: 4-6%, antioxidant: 3-5%, flame retardant: 2-4%, polypropylene wax: 1-3%, antioxidant: 3-5%, softener: 2-5%. These materials are melt-extruded and shaped at high temperature, resulting in high adhesion and waterproof performance. The self-adhesive waterproof layer 4 can isolate moisture transmitted from the wall to the outside, ensuring that the entire insulation system is protected from moisture ingress. Due to its self-adhesiveness, it can be directly bonded to the substrate without the need for additional mortar. Its initial and final strength are higher than the bonding strength between mortar and boards, and there is no risk of mortar failure. In specific implementations, the asphalt self-adhesive waterproof layer can also be made using other existing asphalt-containing materials, not limited to the above formula.
[0028] like Figure 3 As shown, in some embodiments, a backing layer 31 is added between the insulation layer 2 and the self-adhesive waterproof layer 4. The backing layer 31 can be made of the same material as the panel. A high-strength resin adhesive layer 5 is used to bond the insulation layer 2 and the backing layer 31. Adding the backing layer 31 can prevent the insulation material of the selected rock wool layer from having poor bonding performance with the self-adhesive waterproof layer 4. This increases the stability of the bonding between the insulation layer 2 and the self-adhesive waterproof layer 4, and also increases the waterproof performance. It further prevents water vapor from the wall from penetrating into the insulation layer 2, improves the service life of the insulation layer 2, and also avoids the insulation layer 2 from increasing its weight and reducing its overall stability due to the entry of a large amount of water.
[0029] like Figure 4 As shown, in some embodiments, a connecting reinforcement layer 32 is provided between the thermal insulation layer 2 and the self-adhesive waterproof layer 4. This layer can be made of fiber mesh fabric. This layer is sandwiched between the thermal insulation layer 2 and the self-adhesive waterproof layer 4 through the adhesion between the self-adhesive waterproof layer 4 and the thermal insulation layer 2, thereby improving the bonding stability of the thermal insulation layer 2 and the self-adhesive waterproof layer 4.
