Description

Technical Field

[0001] The invention relates to the technical field of roof covering layers, and in particular to a root puncture-resistant waterproof coiled material and a preparation method thereof. Background Art

[0002] Green roof refers to a roof that is covered with soil or loose materials such as sawdust and vermiculite, and plants are planted on the roof waterproof layer to play a role of heat insulation. Green roof projects generally consist of multiple technologies such as planting, waterproofing, drainage and storage, thermal insulation, etc., among which waterproofing is particularly important. Green projects require that waterproof materials must have root puncture resistance while being waterproof to prevent plant roots from damaging the waterproof layer, thermal insulation layer and even the structural layer to protect the safety of the entire project; at the same time, waterproof materials must ensure the normal growth of plants while blocking roots.

[0003] There are two main types of root-penetration-resistant waterproof materials: root-penetration-resistant waterproof membranes and root-penetration-resistant waterproof coatings. The root-penetration-resistant waterproof membranes involved in the market are mainly modified asphalt waterproof membranes and polymer waterproof membranes. The strength and hardness of polymer waterproof membranes can achieve root-blocking effects, while modified asphalt waterproof membranes mainly achieve root-penetration resistance by adding chemical root-blocking agents. Root-penetration-resistant waterproof coatings mainly include polyureas, but the construction method of polyureas has high requirements for personnel, and few can actually be used in the market; there are also some polyurethane waterproof coatings that achieve root-blocking properties by adding chemical root-blocking agents.

[0004] The mechanism of action of chemical root barrier materials is to add some biological additives that can be used to inhibit the growth of plant roots into the elastic asphalt coating. Because asphalt is a relatively soft type of organic material, it is very easy to blend with additives. When the plant root tip grows to the coating layer, the root keratinizes under the action of the additive and will not continue to grow, thereby destroying the underlying matrix, so that the coil can continue to play a waterproofing function. There are several major types of chemical root barrier agents currently in use, one is phenoxypropionate polyether, the other is phenoxypropionate compounds, and copper root barrier agents.

[0005] Chinese patent 202010720276.2 provides a root-penetration-resistant waterproofing membrane for a planted roof, comprising a base and an asphalt layer and a root-blocking layer sequentially arranged on the base; wherein the root-blocking layer comprises a waterproof paint surface and a composite nano-copper uniformly dispersed in the waterproof paint surface, the composite nano-copper comprises nano-copper particles and an organic layer uniformly coated on the surface of the nano-copper particles, and the organic layer is a polyacrylamide layer or a polyacrylate layer. The root-penetration-resistant waterproofing membrane for a planted roof has excellent waterproof and root-penetration-resistant properties and has excellent application prospects.

[0006] Chinese patent 201410322553.9 discloses a composite root-resistant waterproof roll for planted roofs and its preparation method, which belongs to the technical field of building waterproof rolls. It includes a base, an asphalt layer dipped on the base, and a high-density strong cross membrane, and the asphalt layer is composed of the following components by weight: 700-1500 parts of 10# asphalt, 700-1500 parts of 90# asphalt, 600-1200 parts of rubber powder, 50-250 parts of SBS, 50-250 parts of APP, 0-150 parts of IPP, 100-400 parts of engine oil, 1000-1800 parts of stone powder, and 20-80 parts of chemical root inhibitors. The advantages of this invention are: it can well ensure the waterproof requirements of the building, and can also resist the invasion of plant roots into the roll for a long time to avoid damage to the roof.

[0007] In the production process of root-penetration-resistant waterproof materials, these types of chemical root inhibitors are added in a physical mixing manner, which makes the root-blocking effect of the material largely dependent on the dispersion uniformity and compatibility of the root inhibitor in the system. There are application problems such as migration or failure of the root inhibitor with environmental changes. In addition, during the use of copper root inhibitors, defects are easily formed due to the weak interface between metal and polymer, which affects the waterproofness of the coiled material. At the same time, the use of copper salts will affect the water resistance of the coiled material, making the durability of the coiled material not high. Organic root inhibitors are also used in practice, but they are easily degraded under sunlight and it is difficult to maintain long-term effectiveness. Summary of the invention

[0008] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is a root puncture-resistant waterproof coiled material and a preparation method thereof.

[0009] The waterproof coiled material of the present invention uses a composite copper substrate as the coiled material substrate, and its mechanical performance is better than that of a long-fiber polyester substrate, because under the same external force, the composite copper substrate is two substrates that bear the force together, and it also overcomes the problem of cracks caused by low-temperature bending when a metal copper foil is used alone as the substrate; the composite copper substrate has high density and high mechanical strength, and achieves the effect of mechanical root blocking from a physical level. The modified copper root blocker in the modified asphalt layer solves the defect of poor dispersibility and easy agglomeration in the mixed system by grafting and modifying nano-copper. The long alkyl chain grafted on its surface has a barrier and hydrophobic effect, which not only does not cause film-forming defects but also effectively improves the stability of the modified copper root blocker. In addition, the functionalized nano-copper can simultaneously exert the advantages of copper ions and 2-(4-chloro-2-methylphenoxy)-ethyl propionate after reacting with ethyl 2-(4-chloro-2-methylphenoxy) propionate, and can better inhibit the penetration of plant roots after compounding. Moreover, after being grafted with hydrophobic alkyl chains, the hydrophobicity of nano-copper is better and more stable, and it will not affect the water resistance of the coil. The obtained coil has the dual functions of waterproofing and preventing plant roots from penetrating. It can withstand plant root puncture without affecting the normal growth of plants, and can maintain the waterproof function for a long time.

[0010] To achieve the above-mentioned purpose, the present invention provides a root-penetration-resistant waterproof coiled material, comprising a base, a modified asphalt layer and an isolation layer; the modified asphalt layer comprises 80 to 150 parts by weight of base asphalt, 11 to 15 parts by weight of SBS elastomer, 15 to 20 parts by weight of softener, 20 to 25 parts by weight of talcum powder, 2 to 5 parts by weight of modified copper root barrier, and 0.1 to 0.5 parts by weight of antioxidant.

[0011] Furthermore, the base is selected from one of long-fiber polyester fiber felt, composite copper base, and copper foil base.

[0012] Furthermore, the isolation layer is selected from one of polyethylene, polyacrylamide and polyurethane.

[0013] Furthermore, the softener is one or a mixture of two or more of cycloalkane oil, aromatic oil, paraffin oil, engine oil and rubber oil.

[0014] Furthermore, the antioxidant is BASF 1010.

[0068] Test Example 1

[0069] According to the test methods in GB / T 35468-2017 "Root-penetration-resistant waterproof membrane for green roofs" and GB / T 328.8-2007 "Test methods for building waterproof membranes Part 8: Tensile properties of asphalt waterproof membranes", the root-penetration-resistant waterproof membranes prepared in the control example and the embodiment were tested for root-penetration-resistant performance and tensile properties. The specific test results are shown in Table 1.

[0070] Table 1 Root barrier and tensile properties test

[0071]

[0072] From the test results of the control example and the embodiment, it can be seen that the root puncture resistance in Example 1 is the best. This may be because the modified copper root inhibitor solves the defect of poor dispersibility and easy agglomeration in the mixed system by grafting and modifying the nano copper. The long alkyl chain grafted on its surface has a barrier and hydrophobic effect, which not only does not cause film formation defects but also effectively improves the stability of the modified copper root inhibitor. In addition, the functionalized nano copper can simultaneously play the advantages of copper ions and 2-(4-chloro-2-methylphenoxy) propionate root blocking after reacting with 2-(4-chloro-2-methylphenoxy)-ethyl propionate, and can better inhibit the penetration of plant roots after compounding. And the test of tensile properties shows that the prepared waterproof coiled materials all have good mechanical properties, while in Example 2, since the base is a long-fiber polyester fiber felt, its density and mechanical strength are not as good as the composite copper base, so the tensile properties are relatively poor.

[0073] Test Example 2

[0074] The waterproof properties of the waterproof membranes prepared in the control example and the embodiment were tested according to the test method in GB 18242-2008 "Elastomer modified asphalt waterproof membranes". The test results are shown in Table 2.

[0075] Table 2 Waterproof test

[0076] Experimental protocol Waterproof performance / 30min Comparative Example 1 0.60MPa watertight Example 1 0.85MPa watertight Example 2 0.75MPa watertight Example 3 0.75MPa watertight Example 4 0.80MPa watertight

[0077] From the waterproof performance test, it can be seen that the modification of nano-copper not only improves the root penetration resistance of the roll material but also improves its waterproofness. This may be due to the hydrophobic long alkyl chains grafted on its surface when the nano-copper is modified. Therefore, the waterproofness of the waterproof roll material obtained in Example 1 is the best.
