Description

TECHNICAL FIELD

[0001] The present application relates to the field of waterproofing membranes, in particular to a high polymer hollow double-sided compression film waterproofing membrane. BACKGROUND

[0002] In the field of new building waterproofing, the performance requirements of waterproofing materials are constantly improving. In particular, two layers of waterproofing are required on steel structure roofs. Most of the methods on the market are to add a waterproof layer between the steel plate and the glass wool, usually using high molecular TPO or PVC membranes. Although the waterproofing is improved, there are the following defects: the above-mentioned membranes are high in cost, inconvenient to install, and the membranes themselves are heavy, which can easily compress the glass wool when installed between the steel plate and the glass wool, thereby affecting the thermal insulation performance of the glass wool, and thus need to be improved. CONTENT OF THE UTILITY MODEL

[0005] By adopting the above technical solution, the first waterproof layer and the second waterproof layer not only provide good waterproofing performance, but also reduce the overall weight and provide certain thermal insulation effect due to the presence of the hollow foamed layer, thereby increasing the multifunctionality of the material. At the same time, the multi-layer structure is firmly combined together through the adhesive layer, thereby enhancing the overall stability and durability.

[0006] Optionally, the hollow foamed layer is a low-density polyethylene layer.

[0007] By adopting the above technical solution, low-density polyethylene has excellent flexibility and chemical stability, can adapt to different construction environments and conditions, and its low density helps to reduce the overall weight, facilitating transportation and installation.

[0008] Optionally, the closed cell rate of the hollow foamed layer is greater than or equal to 95%, the thermal conductivity is less than or equal to 0.033 W / (m·K), and the thickness is 0.5-2.0 mm.

[0009] By adopting the above technical scheme, the high closed pore rate ensures excellent heat insulation performance, and the low thermal conductivity further enhances this, so that the material can effectively maintain the indoor temperature in cold or hot environments and improve energy efficiency. The appropriate thickness range ensures the best cost-effectiveness ratio without sacrificing performance.

[0010] Optionally, the reinforced protective layer is a glass fiber non-woven fabric layer.

[0011] By adopting the above technical scheme, the glass fiber non-woven fabric has high strength and durability, can effectively resist external physical damage, prolong the service life of the product, and has certain resistance to environmental factors such as ultraviolet rays and oxidation. Not only can it increase the heat resistance of the hollow waterproof layer, but also can improve the strength and puncture resistance of the overall roll material, and may also increase the dimensional stability of the whole, greatly increasing the ease of installation. It can also avoid problems such as curling of the lap joint edge caused by thermal expansion and contraction of the roll material in outdoor harsh environments, greatly improving the flatness and appearance quality of the product, and improving the reliability of the self-adhesive part of the waterproof roll material.

[0012] Optionally, the outer side of the reinforced protective layer is connected with a wear-resistant layer, and the thickness is 0.5-1.0mm.

[0013] By adopting the above technical scheme, the addition of the wear-resistant layer can significantly improve the wear resistance of the product surface, especially for areas that need to be frequently walked on or laid on the ground, improving the safety and durability of use.

[0014] Optionally, the wear-resistant layer is a nitrile rubber layer.

[0015] By adopting the above technical scheme, nitrile rubber has excellent wear resistance, oil resistance and aging resistance, and is very suitable for use as a wear-resistant layer, and can maintain its functional properties for a long time in harsh environments.

[0016] Optionally, the adhesive layer is a butyl rubber layer.

[0017] By adopting the above technical scheme, butyl rubber has good air and water tightness, and as an adhesive layer material, it can ensure the tight combination between the layers, prevent moisture penetration, and enhance the sealing effect of the entire waterproof roll material.

[0018] Optionally, the first waterproof layer and the second waterproof layer are both polyvinyl chloride layers.

[0019] By adopting the above technical scheme, polyvinyl chloride has good mechanical strength, chemical stability and waterproof performance, and is an ideal choice for waterproof materials. The use of PVC on both sides can provide double protection and further enhance the waterproof effect.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1、The first waterproof layer and the second waterproof layer not only provide good waterproof performance, but also reduce the overall weight and provide certain thermal insulation effect due to the presence of the hollow foaming layer, increasing the multifunctionality of the material; at the same time, the multi-layer structure is firmly combined together through the adhesive layer, enhancing the overall stability and durability.

[0022] 2、The low-density polyethylene has excellent flexibility and chemical stability, can adapt to different construction environments and conditions, and at the same time, its low density helps to reduce the overall weight, facilitating transportation and installation.

[0029] The embodiment of the present application discloses a polymer hollow double-sided pressure film waterproof roll material. Figure 1 , comprising a first waterproof layer 1 and a second waterproof layer 2, a hollow foaming layer 3 is arranged between the first waterproof layer 1 and the second waterproof layer 2, and an enhanced protection layer 4 is arranged on the outer side of the second waterproof layer 2. The first waterproof layer 1, the hollow foaming layer 3, the second waterproof layer 2 and the enhanced protection layer 4 are mutually adhered through an adhesive layer. The first waterproof layer 1 and the second waterproof layer 2 not only provide good waterproof performance, but also reduce the overall weight and provide certain thermal insulation effect due to the presence of the hollow foaming layer 3, and the multifunctionality of the material is increased; at the same time, the multi-layer structure is firmly combined together through the adhesive layer, and the stability and durability of the whole are enhanced.

[0030] Referring to Figure 1 , the hollow foaming layer 3 is a low-density polyethylene layer. The low-density polyethylene has excellent flexibility and chemical stability, can adapt to different construction environments and conditions, and at the same time, the low density thereof helps to reduce the overall weight, facilitating transportation and installation. The closed cell rate of the hollow foaming layer 3 is greater than or equal to 95%, the thermal conductivity is less than or equal to 0.033 W / (m·K), and the thickness is 0.5-2.0 mm. The high closed cell rate ensures excellent thermal insulation performance, and the low thermal conductivity further strengthens this point, so that the material can effectively maintain the indoor temperature in cold or hot environments, improving energy efficiency. The appropriate thickness range ensures the best cost-benefit ratio without sacrificing performance.

[0031] Referring to Figure 1 , the enhanced protection layer 4 is a glass fiber non-woven fabric layer. The glass fiber non-woven fabric has high strength and durability, can effectively resist external physical damage, prolong the service life of the product, and has certain resistance to environmental factors such as ultraviolet rays and oxidation. Not only can the heat resistance of the hollow waterproof layer be increased, but also the strength and puncture resistance of the whole roll material can be improved, and the dimensional stability of the whole can also be increased. The ease of installation is also greatly increased. Avoiding the problems such as curling of the lap joint edge of the roll material due to thermal expansion and contraction in outdoor harsh environments, greatly improving the flatness and appearance quality of the product, and improving the reliability of the self-adhesive part of the waterproof roll material.

[0032] Referring to Figure 1 , the outer side of the enhanced protection layer 4 is adhered with a wear-resistant layer 5, and the wear-resistant layer 5 is a nitrile rubber layer with a thickness of 0.5-1.0 mm. The addition of the wear-resistant layer 5 can significantly improve the anti-wear performance of the product surface, especially suitable for ground laying or areas that need to be frequently walked on, improving the safety and durability of use. The nitrile rubber has excellent wear resistance, oil resistance and aging resistance, and is very suitable for use as the wear-resistant layer 5, and can maintain its functional properties for a long time in harsh environments.

[0033] Referring to Figure 1The adhesive layer is a butyl rubber layer, the butyl rubber has good air tightness and water tightness, as the adhesive layer material, it can ensure the close combination between the layers, prevent moisture penetration, and enhance the sealing effect of the whole waterproof roll material.

[0034] Referring to Figure 1 The first waterproof layer 1 and the second waterproof layer 2 are both polyvinyl chloride layers. Polyvinyl chloride has good mechanical strength, chemical stability and waterproof performance, and is an ideal waterproof material selection. The use of PVC on both sides can provide double protection and further strengthen the waterproof effect.

[0035] The implementation principle of the high polymer hollow double-sided press film waterproof roll material in the embodiment of the application is as follows: the first waterproof layer 1 and the second waterproof layer 2 not only provide good waterproof performance, but also, due to the presence of the hollow foaming layer 3, reduce the overall weight and provide certain thermal insulation effect, increase the multifunctionality of the material; at the same time, the multi-layer structure is firmly combined together through the adhesive layer, and the overall stability and durability are enhanced.
