Description

Technical Field

[0001] The present invention relates to the technical field of modified asphalt, and in particular to a silicon-based multi-solvent asphalt bonding material and a preparation method and application thereof. Background Art

[0002] The bonding layer refers to the middle layer that is laid in the road and bridge structure and plays a role of "connecting the upper and lower layers". It mainly has two functions. One is to play its bonding role to firmly bond the upper and lower layers together, thereby improving the mechanical stability of the entire pavement structure; the other is to act as a waterproof layer to block moisture from penetrating into the lower structure and prevent related water damage. In the actual application of roads and bridges, the bonding layer is mainly set between the cement concrete pavement and the additional asphalt layer, between the old asphalt pavement and the new asphalt pavement, between the cement concrete bridge deck and the asphalt additional layer, and between the steel bridge deck and the asphalt additional layer. The bonding layer has now become an indispensable part of the road and bridge structure.

[0003] At present, the solvents used to prepare solvent-based asphalt bonding materials are mostly toluene, xylene and other organic solvents that are toxic and harmful to the human body and the environment, which are not in line with the concept of environmental protection and sustainable development. Moreover, the solvent-based bonding materials currently used still have mechanical defects such as slip failure, peeling and cracking, and poor resistance to shear displacement in the bonding layer under heavy traffic. In addition, the focus of attention on the bonding layer is concentrated on the later road performance, ignoring the bonding performance of the material itself. In fact, the initial bonding performance, continuous bonding ability and bonding strength between interfaces of the bonding material itself are all related to the overall performance of the bonding layer.

[0004] Therefore, in response to the shortcomings of current research, comprehensive consideration of the toxic effects of solvent-based bonding materials, the bonding properties of the materials themselves, and the key road performance as a bonding layer, through in-depth research, a new generation of low-toxic and high-efficiency solvent-based asphalt base bonding materials have been prepared, which has great practical significance for promoting the green and sustainable development of bonding layer technology for road and bridge projects and improving the overall level of the industry. Summary of the invention

[0005] The present invention aims to provide a silicon-based multi-solvent asphalt binder material and a preparation method and application thereof, so as to solve the technical problem that the solvent toxicity of the existing asphalt binder material is relatively high and reduces its safety in use.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] A silicon-based multi-solvent asphalt bonding material comprises the following raw materials in parts by mass: 11 to 45 parts of asphalt, 5.5 to 17 parts of a modifier and 50 to 75 parts of a ternary system solvent, wherein the modifier comprises a silane coupling agent, and the ternary system solvent comprises the following raw materials in parts by volume: 1 to 5 parts of cycloalkanes, 1 to 5 parts of acetates and 2 to 6 parts of tetrahydrofuran.

[0008] Preferably, as an improvement, the modifier further comprises SBS and resin; the modifier comprises the following raw materials in parts by weight: 0.5 to 5 parts of silane coupling agent, 4 to 9 parts of SBS, and 1 to 3 parts of resin.

[0009] Preferably, as an improvement, the cycloalkane is any one of cycloethane, cyclopentane, cyclohexane and cycloheptane, and the acetate is any one of methyl acetate and ethyl acetate.

[0010] Preferably, as an improvement, the silane coupling agent is a combination of one or more of alkoxysilane, vinylsilane and epoxysilane.

[0011] Preferably, as an improvement, the alkoxysilane is one or more combinations of TES and TMOS, the vinyl silane is one or more combinations of A-121 and A-173, and the epoxy silane is one or more combinations of KH-560 and A-186.

[0012] Preferably, as an improvement, the resin is a natural resin or a synthetic resin, including one or more combinations of terpene, rosin, phenolic resin, and petroleum resin.

[0013] Preferably, as an improvement, the present scheme also provides a method for preparing a silicon-based multi-solvent asphalt binder, comprising the following contents: adding the materials measured in the above proportions to a solvent, treating at 20-60°C and 0-300rpm, waiting for them to be fully dissolved, stirring and mixing evenly, and obtaining a solvent-based asphalt binder.

[0014] Preferably, as an improvement, the present invention further provides an application of a silicon-based multi-solvent asphalt bonding material, wherein the solvent-based asphalt bonding material prepared above is applied to any base pavement for laying a new asphalt pavement, wherein the base pavement includes any one of a cement concrete pavement, an old asphalt pavement, a cement concrete bridge deck or a steel bridge deck, and the spreading amount is 0.4-1.4 kg / m 2 .

[0015] The principles and advantages of this solution are:

[0016] In response to the problem of poor solvent safety, the applicant tried to use low-toxic solvents as substitutes. However, the existing low-toxic solvents have the problem of solubility deviation and cannot take into account both low toxicity and solubility. This solution uses a combination of a ternary system solvent, a modifier and asphalt to form a bonding material. The ternary system solvent combines three solvents, making it not only low toxic, but also has a high solubility in asphalt, which helps to improve the overall bonding performance of the bonding material. In addition, this solution uses a combination of silane coupling agent, SBS, and resin as modifiers. When used in combination with asphalt, it effectively improves the overall bonding performance of the bonding material, and it interacts with the ternary system solvent and asphalt to synergistically enhance the effect, effectively improving the bonding effect of the bonding material on the skeleton material and the base pavement, thereby improving the asphalt paving effect.

[0017] 1. Compared with the toxic asphalt solvents used in the prior art, this solution uses a combination of low-toxic solvents to obtain solvents for asphalt binder materials. However, the solubility and efficiency of low-toxic organic solvents for asphalt are somewhat different from those of commonly used solvents for preparing asphalt binder materials (such as toluene and xylene). This solution mixes and compounds several low-toxic single solvents to form an efficient multi-solvent to enhance the solubility of raw materials, thereby achieving the purpose of replacing toluene and xylene to prepare asphalt binder materials, thereby effectively improving the safety of asphalt production.

[0018] 2. This solution can improve the initial bonding performance, continuous bonding ability and interfacial bonding strength of the bonding material itself, and improve its ability to resist water damage by adding an additive silane coupling agent to the solvent-based asphalt bonding material. Specifically, the principle of silane coupling agent as a tackifier is that it has two groups (specifically silane group (Si-OR) and organic functional groups (such as amino, methyl, epoxy, etc.)): one group can be combined with the bonded skeleton material; and the other group can be combined with the polymer material or the bonding agent, thereby forming a strong chemical bond at the bonding interface, thereby improving the bonding strength.

[0019] 3. This scheme adds SBS, solid asphalt and other additives into the ternary system solvent in combination, and stirs and mixes them evenly at room temperature or with appropriate heating until they are fully dissolved, thereby obtaining a silicon-based multi-solvent asphalt bonding material. The obtained bonding material can greatly improve the bonding and water resistance of asphalt and has extremely low toxicity.

[0020] 4. This solution effectively improves the bonding effect of the bonding material on the base pavement and asphalt, and improves the performance of the newly paved asphalt pavement by applying the above-mentioned bonding material to any base pavement for laying new asphalt pavement, including any of cement concrete pavement, old asphalt pavement, cement concrete bridge deck or steel bridge deck, and by limiting its spreading amount. The applicant has found through long-term experiments that insufficient spreading amount will lead to the loss of asphalt quality in the bonding layer, showing poor bonding effect; while excessive spreading of asphalt bonding material will cause excessive capillary loss, reduce the actual amount of asphalt retained in the bonding layer, and is not conducive to long-term bonding.

[0075] Experimental Example 1: Effect of different volume ratios on the solubility of ternary system solvents

[0076] The raw materials (cyclohexane, ethyl acetate, tetrahydrofuran as an example) were prepared into ternary system solvents (such as Examples 5 to 11) in different volumes, and their solubility combination parameters (including δ d , δ P , δ H , δ), with xylene as control. The test results are shown in Table 1.

[0077] Table 1 Solubility combination parameters under different volume ratios

[0078]

[0079]

[0080] Asphalt is an extremely complex mixture, its solubility combination parameters cannot be accurately obtained, but its overall solubility parameter is close to that of xylene. Therefore, this paper uses xylene to approximate No. 70 petroleum asphalt (17.8-18.2 (J / cm3) 1 / 2 ) solubility combination parameters. Experimental data show that by comparing the solubility combination parameters with xylene, the ternary system solvents in this scheme are very similar to No. 70 petroleum asphalt in solubility parameters. In theory, they should have good solubility in asphalt, which will indirectly improve the performance of the bonding material in this scheme. If one of the raw materials is too much (taking cyclohexane as an example, comparative examples 5 to 8), the solubility of the resulting ternary system solvent will deviate relatively from the solubility of xylene, reducing the solubility of the remaining asphalts, and thus reducing the performance of the prepared bonding material.

[0081] Given that the above solvent combinations have similar solubility, they can theoretically have good solubility in asphalt. The applicant conducted a comprehensive analysis of the various indicators of the solubility combination parameters, and further selected the following three ratio schemes as examples to conduct a dissolution efficiency test of the ternary system solvent to demonstrate the dissolution efficiency of the ternary system solvent for asphalt. The results are shown in Table 2.

[0082] Table 2 Dissolution efficiency of ternary system solvents for No. 70 asphalt

[0083]

[0084] The experimental data show that the dissolution performance test data of the asphalt can determine that the ternary system solvents of this scheme all have high dissolution performance, among which the ternary system solvent ratio of cyclohexane: ethyl acetate: tetrahydrofuran = 3:3:4 has the best dissolution performance. Since the solubility combination parameters of the solvents obtained from different combinations in this scheme are similar, therefore, when the ternary system solvents of the above three combinations have good dissolution performance, it is speculated that the ternary system solvents of other combinations in this scheme also have high dissolution performance.

[0085] Experimental Example 2: Comparison of the properties of the produced adhesive materials

[0086] The properties of the solvent-based asphalt binder materials produced in Examples 1 to 4 and Comparative Examples 1 to 4 of this solution were tested with reference to GB / T 4852-2002, GB / T 4851 and GB / T 16777. The results are shown in Table 3.

[0087] Table 3 Differences in performance of solvent-based asphalt adhesive materials produced by Examples 1 to 4 and Comparative Examples 1 to 4

[0089] Experimental data show that changing the dosage of any material in the binder will weaken the bonding strength of the binder to varying degrees. At the same time, compared with the performance of a certain solvent-based asphalt binder on the market, the bonding material obtained by improving the solvent in this scheme is as good as or even better than the existing technology, but can reduce toxicity and make production safer.

[0090] Experimental Example 3: Effect of pull-out strength at different temperatures in asphalt-asphalt system

[0091] The existing SBS modified emulsified asphalt (abbreviated as RB, a commercial product), asphalt binder (abbreviated as WA, a commercial product) and the bonding material obtained in the embodiment were used as experimental objects. The tensile strength of the experimental objects was tested under different temperatures (including 5°C, 25°C, and 60°C) and different systems (including asphalt-asphalt system, cement-asphalt system, and steel plate-asphalt system). The experimental results are recorded in Tables 4 to 6.

[0098] Experimental data show that compared with the commonly used products RB and WA on the market, the bonding material produced by this solution has better tensile strength, thereby improving the stability and durability of asphalt paving on different road surfaces as follows.

[0099] Experimental Example 4: Performance comparison between different market products and this solution’s bonding materials

[0100] The existing SBS modified emulsified asphalt (abbreviated as RB, a commercial product), asphalt binder (abbreviated as WA, a commercial product) and the bonding materials obtained in Examples 1-3 (corresponding abbreviations NA, NB, NC) were used as experimental objects to test their initial adhesion performance, sustained adhesion performance and bonding strength. The results are detailed in Figure 1 .

[0101] Experimental data show that the bonding material prepared by combining different raw materials in this scheme is superior to the existing SBS modified emulsified asphalt (abbreviated as RB) and asphalt binder (abbreviated as WA) in terms of initial adhesion, sustained adhesion and bonding strength, and has better bonding performance.

[0102] Experimental Example 4: Application Effect of Solvent-Based Asphalt Binder

[0103] Taking cement concrete pavement as an example, the solvent-based asphalt binder material is set in multiple gradients according to the gradient dosage (i.e., the spreading amount) and used on any base pavement for paving new asphalt pavement. Its application effect is tested according to JT / T983-2015. The results are shown in Table 7.

[0106] Experimental data show that when the amount of adhesive material applied is 0.6 kg / m 2 When the asphalt pavement is heated, the tensile strength and oblique shear strength of the asphalt pavement are higher, which effectively improves the performance of the asphalt pavement.
