Description

Technical Field

[0001] This application relates to the field of road engineering materials technology, and in particular to an anchoring agent production process and production equipment. Background Technology

[0002] Anchoring agents are chemical bonding materials used to fix metal fasteners such as bolts and reinforcing bars to concrete, rock, or masonry. Classified by chemical composition, anchoring agents commonly used in engineering applications are mainly divided into four categories: The first category is unsaturated polyester resin anchoring agents, which have the characteristics of fast curing speed and low cost, but relatively weak durability and corrosion resistance; the second category is vinyl ester resin anchoring agents, whose overall performance is between unsaturated polyester and epoxy, suitable for moderately corrosive environments; the third category is inorganic cement-based anchoring agents, which use high-strength cement as the main cementing material, have good environmental performance but limited bonding strength; and the fourth category is epoxy resin anchoring agents, which use bisphenol A type epoxy resin as the main material. Due to its excellent bonding strength, good corrosion resistance, extremely low shrinkage rate, and high compatibility with concrete and steel substrates, it has become the preferred material for high-end reinforcement projects.

[0003] Epoxy resin anchoring agents are commonly supplied in engineering practice in a two-component package, consisting of component A and component B. Before use, they are mixed in a specific mass ratio and injected into the borehole. Component A typically uses bisphenol A epoxy resin as the main binder, supplemented with inert fillers such as quartz sand and calcium carbonate to adjust consistency and reduce costs. An active diluent is added to control the application viscosity, and a thixotropic agent is added to prevent sagging on vertical surfaces. Component B uses aliphatic amines or polyether amine compounds as the main curing agent, also filled with appropriate fillers to match the physical state of component A. The core advantage of this two-component system is that the three-dimensional cross-linked network formed after epoxy resin curing can simultaneously generate strong physical adsorption and chemical bonding with the iron oxide layer on the surface of the reinforcing steel and the silicate matrix of the concrete matrix, thus giving the anchoring system a pull-out bearing capacity far exceeding that of mechanical expansion bolts.

[0004] However, existing general-purpose epoxy resin anchoring agents have long faced the problem of slow curing speed in practical engineering applications, especially in low-temperature environments. Under standard conditions, complete curing requires 24 to 72 hours. When the ambient temperature drops below 5°C, the curing cycle extends to more than 3 days. In sub-zero environments, effective curing is virtually impossible, severely restricting the progress of outdoor construction in winter. Summary of the Invention

[0005] In view of this, this application provides an anchoring agent production process that solves the problem of long curing time for epoxy resin anchoring agents.

[0006] The present application provides a manufacturing process and preparation method for an anchoring agent, which adopts the following technical solution:

[0007] An anchoring agent manufacturing process includes the following steps: S1: Mix E-51 bisphenol A type epoxy resin, benzoic acid, and KH-550 silane coupling agent evenly, add pre-dried 80-120 mesh quartz sand filler, and stir at high speed of 1100-1300 rpm for 25-35 minutes under heating to complete the in-situ surface modification of quartz sand filler; after the modified quartz sand filler cools, add glycidyl ether reactive diluent, 2000 mesh fumed silica thixotropic agent, BYK-066N defoamer, and antioxidant 1010, stir evenly, and then ultrasonically disperse for 10-20 minutes to obtain agent A; S2: Slowly add E-51 epoxy resin to polyetheramine D230 modified curing agent, heat to 40-45℃, and keep the reaction at this temperature for 1-2 hours to complete the pre-activation of the curing agent; cool to room temperature, add accelerator, pre-dried 120-200 mesh quartz sand filler, 2000 mesh fumed silica thixotropic agent, and KH-550 silane coupling agent, stir evenly, seal and let stand for 20-28 hours to release the gas, and obtain agent B; S3: When using, mix agent A and agent B evenly at a weight ratio of 3:1.

[0008] By adopting the above technical solution, on the one hand, during the preparation of agent B, a small amount of epoxy resin and polyetheramine are reacted under certain conditions to allow for partial ring-opening addition. The secondary amine intermediate generated by this pre-reaction can be further transformed to form tertiary amine functional groups and hydroxyl byproducts in situ within agent B. Tertiary amines have catalytic activity for the ring-opening reaction of epoxy groups, while hydroxyl groups can enhance the reactivity of the epoxy ring through hydrogen bonding. When the pre-activated agent B is mixed with agent A, these existing catalytic centers immediately take effect, eliminating the need for a long induction waiting stage. Within minutes of mixing, the rapid cross-linking stage before gelation can begin, significantly improving the early curing rate. On the other hand, the surface modification step of the filler is directly embedded into the preparation process of agent A. KH-550 undergoes hydrolysis and dehydrates and condenses with the silanol groups on the surface of quartz sand to form a covalently bonded siloxane graft layer. The organic functional ends of the coupling agent molecules extend into the surrounding resin phase to participate in subsequent cross-linking. This in-situ modification method changes the interface between the filler and the resin from physical contact to chemical bonding, significantly improving the interfacial shear transfer strength and further shortening the time required for the curing reaction.

[0009] Optionally, the components of Agent A, by weight, are: 38-42 parts E-51 epoxy resin, 2-3 parts benzoic acid, 0.8-1.2 parts KH-550 silane coupling agent, 46-50 parts 80-120 mesh quartz sand, 4-6 parts glycidyl ether reactive diluent, 1.8-2.2 parts 2000 mesh fumed silica, 0.1-0.3 parts BYK-066N defoamer, and 0.2-0.4 parts antioxidant 1010.

[0010] By adopting the above technical solution and optimizing the proportion of each component, the optimal balance of viscosity, thixotropy, exothermicity and mechanical properties of the system is achieved; when benzoic acid is added at the optimal amount, the exothermic effect just meets the reaction requirements at -5℃, and the maximum temperature of the system is stable at 55-58℃, with no risk of overheating.

[0011] Optionally, the drying process of the quartz sand filler in step S1 is as follows: place the quartz sand and fumed silica in an oven at 100-110℃ and dry for 1.5-2.5 hours, then remove and cool to room temperature for later use.

[0012] By adopting the above technical solution, the drying pretreatment removes the free water adsorbed on the surface of the inorganic filler, prevents free water from competing with epoxy groups, ensures the number of effective functional groups for constructing the crosslinking network, and effectively ensures the crosslinking density; secondly, it prevents the formation of a water transition layer and ensures the stress transmission efficiency.

[0013] Optionally, the glycidyl ether reactive diluent in step S1 is 692 benzyl glycidyl ether.

[0014] By adopting the above technical solution, the self-epoxy group carried by 692 benzyl glycidyl ether can participate in the crosslinking reaction of amine curing agents during the curing process and be incorporated into the final polymer network. This characteristic allows 692 benzyl glycidyl ether to reduce the viscosity of the system without reducing the glass transition temperature and mechanical strength of the cured product. In addition, the benzene ring in the 692 benzyl glycidyl ether molecule provides a certain rigidity skeleton contribution, which is beneficial to maintaining the modulus and heat deformation resistance of the cured product. Most importantly, it has the effect of accelerating the crosslinking reaction at room temperature.

[0015] Optionally, the glycidyl ether reactive diluent in step S1 is X-632 tert-butyl-terminated ethylene glycol diglycidyl ether.

[0016] By adopting the above technical solution, the molecular structure of X-632 tert-butyl-terminated ethylene glycol diglycidyl ether is characterized by an epoxy group at each end, connected by a flexible ethylene glycol segment in the middle, with a tert-butyl-terminated group at one end of the chain. This structure endows it with properties beneficial for low-temperature construction. X-632 tert-butyl-terminated ethylene glycol diglycidyl ether exhibits excellent low-temperature compliance. The tert-butyl groups are spherically symmetrically distributed with weak intermolecular cohesion. Combined with the flexibility of the ethylene glycol segment, this results in a low dynamic viscosity of X-632 tert-butyl-terminated ethylene glycol diglycidyl ether at -5 degrees Celsius, ensuring good flowability of Agent A during injection construction at low temperatures.

[0017] Optionally, the process parameters for in-situ surface modification of quartz sand filler in step S1 are: temperature 80℃, stirring speed 1200rpm, and stirring time 30 minutes.

[0018] By adopting the above technical solution, controlling the temperature at 80℃ can effectively ensure the rate of hydrolysis reaction, quickly form a grafted layer with sufficient coverage on the filler surface, and effectively improve the actual utilization rate of silane coupling agent.

[0019] Optionally, the process parameters for ultrasonic dispersion in step S1 are: frequency 20kHz, processing time 15 minutes, and system temperature controlled at 35-40℃.

[0020] Optionally, the process parameters for the pre-activation of agent B in step S2 are as follows: the epoxy resin used for pre-activation is 6% of the total mass of agent B, the amount of polyetheramine D230 is 28-32 parts, the pre-reaction temperature is 42℃, the heat preservation time is 1.5 hours, and the temperature during the feeding process is ≤38℃.

[0021] Optionally, the preparation step after the pre-activation in step S2 is as follows: cool down to 20-25℃, add 1.8-2.2 parts of DMP-30 accelerator, 58-62 parts of 120-200 mesh quartz sand, 2.8-3.2 parts of 2000 mesh fumed silica, and 0.4-0.6 parts of KH-550 silane coupling agent, stir at 800 rpm for 30 minutes, seal and let stand for 24 hours to release the gas.

[0022] By adopting the above technical solution, DMP-30 is a broad-spectrum epoxy curing accelerator. Its special tertiary amine structure gives it both Lewis base catalysis and hydrogen bond activation promoting effects. The quartz sand selected is of medium fineness (120-200 mesh) to obtain a larger specific surface area with the same filler volume fraction, thereby increasing the thixotropic consistency of agent B and making its rheological curve as close as possible to that of agent A during mixing, thus facilitating more uniform mixing at the molecular level. Stirring at 800 rpm for 30 minutes is sufficient to achieve uniform dispersion of each component without entraining excessive air. The final sealing and standing for 24 hours removes microbubbles trapped in the adhesive. The sealing process, while venting, also isolates the adhesive from carbon dioxide and moisture in the air, preventing the amine curing agent from undergoing a carbamate-induced whitening side reaction.

[0023] Secondly, this application also provides an anchoring agent production equipment for the above-mentioned anchoring agent production process, including an oven, a mixing tank with temperature control and speed regulation functions, an ultrasonic disperser, and a sealing and packaging device.

[0024] In summary, this application includes the following beneficial technical effects: 1. This application utilizes a pre-activated autocatalytic system to reduce the traditional 20-30 minute curing induction period to less than 3 minutes. Combined with a controllable, self-exothermic mechanism, it provides continuous thermodynamic impetus throughout the reaction process, ultimately achieving: complete curing time ≤ 8 hours at room temperature, ≤ 12 hours at 5℃, and over 95% curing degree of crosslinking within 24 hours at -5℃. This eliminates the need for additional heating tents, hot water baths, or infrared lamps for outdoor construction in winter, significantly reducing construction costs and the risk of project delays.

[0025] 2. By precisely controlling the pre-activation degree and the exothermic reaction of benzoic acid, this application achieves rapid curing while maintaining a stable construction operation time of more than 15 minutes, providing ample time for on-site workers to inject adhesive, insert reinforcing bars, make adjustments, and trim the hole openings, thus significantly reducing the rework rate caused by rushed operations.

[0026] 3. The products of this application can be applied normally and achieve qualified curing results within a wide temperature range, which is extremely rare among similar products. In particular, in the temperature range of -5℃ to 5℃, which is traditionally regarded as a "forbidden zone" for epoxy anchoring agents, this application has successfully overcome the physical and chemical limitations by relying on the viscosity advantage of X-632 low-temperature diluent and the temperature compensation mechanism of benzoic acid's self-exothermic temperature.

[0033] Example 2 The only difference between this embodiment and Example 1 is that the amount of benzoic acid in Agent A is reduced from 2.5 parts to 1.5 parts.

[0036] Example 5 The only difference between this embodiment and Embodiment 1 is that all E-51 epoxy resin is added at once during the room temperature mixing stage without pre-activation.

[0037] Comparative Example 1 S1: 42 parts of E-51 epoxy resin, 6 parts of dibutyl phthalate (non-reactive diluent), 48 parts of 80-120 mesh quartz sand, 2 parts of 2000 mesh fumed silica, and 0.2 parts of BYK-066N defoamer are stirred at 800 rpm for 30 minutes at room temperature until homogeneous to obtain Agent A.

[0038] Comparative Example 2 The only difference between this comparative example and Comparative Example 1 is that the amount of DMP-30 accelerator was significantly increased from 2 parts to 8 parts.

[0039] Performance testing I. Test Basis and Methods The performance tests of each embodiment and comparative example in this application were strictly carried out in accordance with the testing methods specified in the national standards GB / T50728-2011 "Technical Specification for Safety Appraisal of Strengthening Materials for Engineering Structures" and JG / T340-2011 "Anchor Bolts for Concrete Structures". The main testing items and corresponding methods are as follows: Curing time determination: Differential scanning calorimetry (DSC) and a combination of finger-dry / finger-touch methods were used. The DSC method recorded the onset time of the exothermic peak of the mixed sample (defined as the end of the induction period) and the time when the total area of ​​the main exothermic peak reached 95% (defined as the complete curing time) in isothermal mode. The finger-dry method, as specified in Appendix GB50367, involved lightly touching the sample surface with clean, dry fingers at regular intervals to determine whether it was no longer sticky (surface drying time) and whether there were no fingerprints remaining (actual drying time). The tests were conducted in parallel under three temperature conditions: (1) standard condition 25℃±2℃; (2) low temperature I setting 5℃±1℃; (3) low temperature II setting -5℃±1℃. Three parallel samples were prepared for each temperature point, and the average value was taken.

[0040] Pull-out strength determination: The test was conducted according to the "Field Pull-out Test Method for Anchors" specified in Clause 4.2.2 of GB / T50728-2011. The substrate was a standard concrete block (150mm × 150mm × 150mm cube) of C30 strength grade. Holes were drilled with a diameter of 25mm and a depth of 150mm. After cleaning the holes, the anchoring agent to be tested was injected, and an HRB400 Φ20 threaded steel bar was inserted (embedded to a depth of 125mm). Pull-out tests were conducted at each preset curing time (8h / 12h / 24h / 72h / 168h). The ultimate pull-out load was recorded and divided by the contact surface area between the steel bar and the anchoring agent to calculate the bond strength. Five valid samples were collected from each group; the highest and lowest values ​​were discarded, and the average value was taken.

[0041] Curing degree determination: Fourier transform infrared spectroscopy (FTIR) was used to track the characteristic absorption peak of epoxy (915 cm⁻¹). - The decay pattern of the asymmetric stretching vibration peak of the epoxy ring at position ¹ over time was analyzed, and the conversion rate of the epoxy groups was calculated using the relative peak area normalization method. Solvent extraction was used to determine the gel content as a cross-validation method.

[0042] Application window determination: The time interval from the start of mixing agents A and B until the viscosity of the mixture rises to the point where it can no longer be smoothly ejected from the injection gun is recorded and defined as the effective operating time (application window). At the same time, the rotational viscosity is measured at six time points after mixing: 5 min, 10 min, 15 min, 20 min, and 30 min (NDJ-1 type rotational viscometer, #4 rotor, 6 rpm), and the viscosity-time curve is plotted.

[0043] Determination of exothermic peak temperature: A mixing and curing experiment was conducted in an insulated cup or a semi-insulated foam box. A K-type thermocouple and a data acquisition device were used to continuously record the temperature change curve at the center of the system, and the highest temperature value and the time to reach the peak were read.

[0044] Defect rate observation: After curing, the sample is cut open along the axial direction and the number of bubbles and the maximum crack length per unit area are counted under an optical microscope (50x magnification) to calculate the defect density index.

[0045] II. Test Results and Data Analysis Table 1. Summary of curing performance of each embodiment and comparative example at different temperatures.

[0046] Table 2 shows the curing performance data of each embodiment and comparative example under low-temperature conditions.

[0047] Comparing Example 1 and Comparative Example 1, the induction period of Example 1 was 2 minutes, while that of Comparative Example 1 was 28 minutes. The complete curing time of Example 1 was 7.5 hours, while that of Comparative Example 1 was 28 hours, resulting in a nearly three-fold increase in curing efficiency. Example 1 employed a pre-activation process using Agent B, where a small amount of E-51 epoxy resin and polyetheramine D230 were pre-reacted at 42°C for 1.5 hours, generating tertiary amine catalytic centers and hydroxyl groups in situ. After mixing, no induction period was required to initiate the crosslinking reaction. Simultaneously, benzoic acid in Agent A constructed a controllable, self-exothermic system, providing continuous thermodynamic driving force throughout the reaction. Therefore, the curing efficiency far exceeded that of Comparative Example 1, which did not employ pre-activation and self-exothermic technology.

[0048] Comparing Example 1 and Comparative Example 2, the construction window for Example 1 was 18 minutes, while for Comparative Example 2 it was 9 minutes, effectively doubling the working time. Comparative Example 2, with its excessive addition of DMP-30 accelerator, resulted in an excessively rapid crosslinking rate and a sharp increase in viscosity, failing to meet the basic operational requirements for on-site gluing, reinforcement insertion, and adjustments. In contrast, Example 1, through precise control of the pre-activation level and the amount of benzoic acid, achieved rapid curing while maintaining a stable construction window of 18 minutes, providing ample operational margin for on-site workers.

[0049] By comparing Examples 1, 2, and 3, the peak temperature of Example 1 was 56°C, that of Example 2 was 42°C, and that of Example 3 was 73°C. The curing rate of Example 2 decreased due to insufficient heat release. In Example 3, the amount of benzoic acid was excessive, and the self-released heat exceeded the reaction requirements. The excessively high system temperature could easily lead to an increase in internal defects in the cured product. The heat release level of Example 1 was mild and continuous, ensuring a stable reaction.

[0050] This application also provides an anchoring agent production equipment, applied in the anchoring agent production process, including an oven, a mixing tank with temperature control and speed regulation functions, an ultrasonic disperser, and a sealing packaging device. The sealing packaging device is used to isolate and package the aforementioned agent A and agent B.

[0051] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
