Description

Technical Field

[0001] The present application relates to the field of waterproof materials, and in particular to a weather-resistant, environmentally friendly, odor-free waterproof coiled material and a preparation method thereof. Background Art

[0002] As a leak-free connection between the engineering foundation and the building, waterproof membrane has the function of protecting the building structure from external water erosion. It is one of the important functional materials in construction. According to the material classification, it can be divided into asphalt waterproof membrane and polymer waterproof membrane.

[0003] Compared with polymer waterproofing membranes, asphalt waterproofing membranes have the characteristics of low cost and easy construction, but poor heat resistance and fatigue resistance. In order to improve the performance shortcomings of asphalt waterproofing membranes, thermoplastic elastomers are generally added to asphalt as modifiers, such as SBS, to improve the elasticity and heat resistance of waterproofing membranes.

[0004] Since asphalt has a pungent smell, asphalt waterproofing membranes also carry a certain odor. In order to reduce the impact of odor on the user experience of asphalt waterproofing membranes, some asphalt waterproofing membranes will add inorganic adsorption materials to absorb the odor, such as activated carbon and montmorillonite. However, the addition of inorganic adsorption materials will cause the low-temperature flexibility of asphalt waterproofing membranes to deteriorate, affecting the durability of the waterproofing membranes. Summary of the invention

[0005] In order to reduce the odor of asphalt waterproof membranes and maintain the durability of the waterproof membranes, the present application provides a weather-resistant, environmentally friendly, odor-free waterproof membrane and a preparation method thereof.

[0006] In the first aspect, the present application provides a weather-resistant, environmentally friendly, odor-free waterproof membrane adopts the following technical solution: A weather-resistant, environmentally friendly, odor-free waterproof roll material comprises a base, both sides of which are sequentially provided with an asphalt layer and an isolation membrane, wherein the asphalt layer is prepared from the following raw materials in parts by weight: Asphalt 100 parts; SBS 4-6 parts; SIS 4-6 servings; 6-8 parts softening oil; 7.5-10 parts of deodorant; 9-13 parts of rubber powder; The deodorant is prepared by modifying montmorillonite with a vinyl silane coupling agent and grafting a deodorant and a styrene-isoprene-butadiene copolymer.

[0007] By adopting the above technical solution, SBS is a styrene-butadiene-styrene block copolymer, SIS is a styrene-isoprene-styrene block copolymer, and SBS and SIS are used as polymer modifiers at the same time to form a cross-linked network structure inside the asphalt, thereby improving the cohesion and bonding ability of the asphalt. The montmorillonite in the deodorizer is an inorganic clay material with a layered structure, which has a strong interlayer adsorption capacity and can adsorb odorous organic matter in the asphalt to reduce the degree of odor emission. In addition, the deodorizer is loaded with montmorillonite as a carrier, and the grafted styrene-isoprene-butadiene copolymer makes the load of the deodorizer more stable, reacts and fixes the organic matter entering the montmorillonite interlayer, and greatly improves the deodorizing effect. In addition, styrene-isoprene-butadiene copolymer is grafted on the surface of montmorillonite, forming good interface compatibility with the SBS and SIS network structures inside the asphalt, improving the dispersibility of montmorillonite in the asphalt and the bonding force between montmorillonite and asphalt, thereby achieving a deodorizing effect while enhancing the weather resistance of the waterproof membrane, especially the low-temperature flexibility, thereby improving the durability of the waterproof membrane.

[0008] Optionally, the raw materials for preparing the deodorant include montmorillonite, vinyl silane coupling agent, deodorant, styrene, isoprene and butadiene in a mass ratio of 1:(0.08-0.12):(0.1-0.15):(0.2-0.3):(0.3-0.4):(0.3-0.4).

[0009] By adopting the above technical scheme and synthesizing the deodorant in the above proportion, the deodorant has good stability. If the proportion of styrene, isoprene and butadiene is too small, the degree of grafting of styrene-isoprene-butadiene copolymer on montmorillonite is reduced, resulting in reduced stability of the deodorant load. If the proportion of styrene, isoprene and butadiene is too large, the degree of grafting of styrene-isoprene-butadiene copolymer on montmorillonite is too high, resulting in limited adsorption capacity of montmorillonite.

[0010] Optionally, the deodorant includes one or both of soy ethyl sulfate morpholine and zinc ricinoleate.

[0011] By adopting the above technical scheme, soybean ethyl sulfate morpholine and zinc ricinoleate react with odorous organic matter under coordination or neutralization, and fix the odor, thereby reducing the degree of odor emission and achieving the purpose of deodorization. In addition, soybean ethyl sulfate morpholine and zinc ricinoleate loaded on montmorillonite have high stability and good persistence of odor removal.

[0012] Optionally, the deodorant is composed of soybean ethyl sulfate morpholine and zinc ricinoleate in a mass ratio of 1:(1.5-3).

[0013] By adopting the above technical scheme, soybean ethyl sulfate morpholine and ricinoleate zinc are compounded according to the above ratio, the adsorption and fixation effect on odorous organic matter can be effectively improved, and the degree of odor emission can be further reduced.

[0014] Optionally, the size of the montmorillonite is 250-300 meshes.

[0015] By adopting the above technical solution, the montmorillonite of the above size has a high adsorption capacity, a good odor removal effect, and little effect on the structural stability of the asphalt waterproofing membrane.

[0016] Optionally, the size of the rubber powder is 400-500 meshes.

[0017] By adopting the above technical solution, the rubber powder can further improve the cohesion of asphalt, thereby improving the peel strength of the waterproof membrane.

[0018] Optionally, the softening oil is aromatic oil.

[0019] By adopting the above technical solution, aromatic oil can improve the heat resistance of waterproof membrane.

[0020] Optionally, the tire base is a polyester tire base.

[0021] Optionally, the isolation film is a PE film.

[0022] In the second aspect, the present application provides a method for preparing a weather-resistant, environmentally friendly, odor-free waterproof membrane using the following technical solution: A method for preparing a weather-resistant, environmentally friendly, odor-free waterproof coiled material comprises the following steps: Heat the asphalt to 130-150℃ to make it molten, then add softening oil, stir evenly and further heat to 160-170℃, then add SBS and SIS, stir evenly, then add deodorant and rubber powder, continue to stir evenly to obtain modified asphalt; The modified asphalt is coated on both sides of the tire base, cooled to form an asphalt layer, and then the surface of the asphalt layer is covered with an isolation film to prepare a weather-resistant, environmentally friendly and odor-free waterproof membrane.

[0023] By adopting the above technical solution, the raw materials are fully mixed in the molten state of asphalt, so that the raw materials are dispersed, especially the deodorant is evenly dispersed, and finally a stable asphalt layer is formed.

[0024] Optionally, the method for preparing the deodorant comprises the following steps: Dispersing montmorillonite in an alcohol solvent, adding a vinyl silane coupling agent, reacting at 60-70°C for 1-2 hours, discharging, filtering, washing, and drying to obtain modified montmorillonite; Add modified montmorillonite, deodorant and emulsifier into a reaction container filled with water, disperse them evenly, add styrene and isoprene and stir them evenly, introduce inert gas into the reaction container for replacement, and then press butadiene into the reaction container with inert gas, heat to 55-65°C, add initiator, and then heat to 70-80°C, continue to react for 8-12 hours, discharge, filter, wash and remove thick liquid, and dry to obtain a deodorizer.

[0025] By adopting the above technical scheme, the vinyl silane coupling agent is connected to the surface of montmorillonite, so that the surface of montmorillonite obtains carbon-carbon double bonds available for polymerization, and the styrene-isoprene-butadiene copolymer is polymerized in the process of the deodorant being loaded on the montmorillonite by emulsion polymerization, thereby improving the grafting effect.

[0026] Optionally, the mass ratio of the montmorillonite, emulsifier, initiator and water is 1:(0.1-0.2):(0.05-0.1):(9-13).

[0027] In summary, this application has the following beneficial effects: 1. This application uses SBS and SIS as polymer modifiers to form a cross-linked network structure inside the asphalt to improve the cohesion and bonding ability of the asphalt. The montmorillonite in the deodorizer is an inorganic clay material with a layered structure, which has a strong interlayer adsorption capacity and can adsorb odorous organic matter in the asphalt to reduce the degree of odor emission. The deodorizer is loaded with montmorillonite as a carrier, and the grafted styrene-isoprene-butadiene copolymer makes the load of the deodorizer more stable, reacts and fixes the organic matter entering the montmorillonite interlayer, and further improves the deodorizing effect.

[0028] 2. The present application grafts styrene-isoprene-butadiene copolymer on the surface of montmorillonite, forming a good interface compatibility with the SBS and SIS network structures inside the asphalt, thereby improving the dispersibility of montmorillonite in the asphalt and the bonding force between montmorillonite and asphalt, thereby achieving a deodorizing effect while enhancing the weather resistance of the waterproof membrane, especially the low-temperature flexibility, thereby improving the durability of the waterproof membrane.

[0059] Performance Testing The waterproof membranes prepared in Examples 1-3 and Comparative Examples 1-6 were taken as samples and subjected to the following tests.

[0060] Purification test: The samples were placed in an environment of 25°C and 60°C, respectively, and the VOCs content generated by the samples was tested using a photoionization detector. The VOCs content measured in Comparative Example 5 was recorded as W, and the VOCs content measured in the other embodiments and comparative examples was recorded as J. The purification rates of the other embodiments and comparative examples except Comparative Example 5 were calculated according to (WJ) / W. The results are shown in Table 1.

[0061] Low temperature flexibility test: refer to the low temperature flexibility test method in GB 18242-2008 "Elastomer modified bitumen waterproof membrane" to obtain the lowest temperature at which no cracks appear on the specimen. The results are shown in Table 2.

[0062] Thermal aging and low temperature flexibility test: Refer to the test methods for thermal aging and low temperature flexibility in GB 18242-2008 "Elastomer modified bitumen waterproof membrane". After thermal aging, a low temperature flexibility test is performed to obtain the lowest temperature at which no cracks appear on the specimen. The results are shown in Table 2.

[0063] Table 1 Table 2 Low temperature flexibility(℃) Low temperature flexibility after heat aging(℃) Example 1 -29 -24 Example 2 -28 -23 Example 3 -29 -23 Comparative Example 1 -27 -22 Comparative Example 2 -17 -9 Comparative Example 3 -22 -16 Comparative Example 4 -23 -15 Comparative Example 5 -29 -25 Comparative Example 6 -28 -24 It can be seen from Table 1 and Table 2 that the addition of the deodorizer prepared in the embodiment can have a good VOCs purification effect on the waterproof membrane, thereby reducing the odor level carried by VOCs and reducing the harm of asphalt volatile gases to the environment or human body, and the low-temperature flexibility and low-temperature flexibility after heat aging meet the standard requirements, the weather resistance is high, and the durability of the waterproof membrane application is met.

[0064] Combining Example 1 with Comparative Examples 5-6, it can be seen that the addition of the deodorizer prepared in the example has little effect on the low-temperature flexibility of the waterproof membrane, and the durability is maintained. Since the higher the temperature, the easier it is for the odor molecules in the asphalt to volatilize, the example is different from the method of directly adding the deodorizer. The method of loading the deodorant with montmorillonite greatly improves the stability of the deodorant, so that the waterproof membrane has a higher purification rate for VOCs at high temperatures and a higher ability to adsorb and fix odor molecules.

[0065] Combining Example 1 with Comparative Example 1, it can be seen that the deodorant can effectively fix odor molecules; combining Example 1 with Comparative Examples 2-4, it can be seen that montmorillonite grafted styrene-isoprene-butadiene copolymer can further stabilize the load of the deodorant in montmorillonite and improve the bonding force between montmorillonite and asphalt, thereby effectively improving the purification rate of VOCs and preventing cracks from occurring at lower temperatures, that is, the odor removal ability and low-temperature flexibility of the waterproof membrane are improved, and it can be seen that the influence of the monomer selectivity in the styrene-isoprene-butadiene copolymer on the copolymer grafting effect.

After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
