In addition, when a parameter is expressed as an integer ≥ 2, it is equivalent to disclosing that the parameter is, for example, an integer of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc.

[0022] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0023] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the present application, an interface self-repairing anchor material is proposed, comprising the following components in parts by weight: 90-100 parts of anchor matrix monomer material, 1-2 parts of anchor matrix polymerization initiator, 5-8 parts of anchor matrix cross-linking agent, 1-2 parts of anchor matrix cross-linking promoter, 1-3 parts of enhancer, 1-2 parts of plasticizer, 25-30 parts of self-repairing molecules and 1-3 parts of solubilizer.

[0024] The interface self-repairing anchor material in this embodiment includes 90-100 parts by weight of anchor matrix monomer material, wherein the anchor matrix monomer material includes butadiene (CAS: 106-99-0), 1,1-dichloroethylene (CAS: 75-35-4) and fluorinated allyl (CAS: 818-92-8) in a mass ratio of 1: 2: 5. In some embodiments, the anchor matrix monomer material may be 90 parts, 91 parts, 92 parts, 93 parts, 94 parts, 95 parts, 96 parts, 97 parts, 98 parts, 99 parts or 100 parts by mass. If the anchor matrix monomer material has a small amount, such as less than 90 parts, the molecular weight of the anchor matrix monomer material is low, resulting in low mechanical properties of the interface self-repairing anchor material. If the anchor matrix monomer material has a large amount, such as more than 100 parts, there will be a large amount of unreacted residual monomers, which will affect the mechanical strength of the interface self-repairing anchor material.

[0025] In some embodiments, the interface self-repairing anchor material includes 1-2 parts by weight of an anchor matrix polymerization initiator, wherein the anchor matrix polymerization initiator is 1,1-diphenylhexyl lithium. In some embodiments, the mass fraction of the anchor matrix polymerization initiator may be 1 part or 2 parts, etc. If the mass fraction of the anchor matrix polymerization initiator is small, such as less than 1 part, a large amount of anchor matrix monomer material is not reacted, and there is a large amount of unreacted residual anchor matrix monomer material, which affects the mechanical strength of the interface self-repairing anchor material. If the mass fraction of the anchor matrix polymerization initiator is large, such as greater than 2 parts, the molecular weight of the anchor matrix monomer material is not high, and the mechanical strength of the interface self-repairing anchor material is low.

[0026] In some embodiments, the interface self-repairing anchor material includes 5-8 parts by weight of an anchor matrix crosslinking agent, wherein the anchor matrix crosslinking agent includes N,N-dimethylisoquinoline-4-sulfonamide (CAS: 1306606-93-8) and propylamine sulfonamide (CAS: 147962-41-2) in a mass ratio of 2:1. In some embodiments, the mass fraction of the anchor matrix crosslinking agent is 5 parts, 6 parts, 7 parts or 8 parts, etc. If the mass fraction of the anchor matrix crosslinking agent is small, such as less than 5 parts, the interface self-repairing anchor material has a low crosslinking density and a low elongation at break. If the mass fraction of the anchor matrix crosslinking agent is large, such as greater than 8 parts, uneven crosslinking, high local crosslinking, and uneven performance of the interface self-repairing anchor material are caused.

[0027] In some embodiments, the interface self-repairing anchor material includes 1-2 parts by weight of an anchor matrix cross-linking promoter, and the anchor matrix cross-linking promoter includes 2-methacryloyloxyethyl thioate (CAS: 126449-41-0) and potassium glycol sulfate (CAS: 59599-54-1) in a mass ratio of 3:1. In some embodiments, the mass fraction of the anchor matrix cross-linking promoter may be 1 part or 2 parts, etc. If the mass fraction of the anchor matrix cross-linking promoter is small, such as less than 1 part, the cross-linking rate of the interface self-repairing anchor material is slow and the cross-linking is insufficient. If the mass fraction of the anchor matrix cross-linking promoter is large, such as greater than 2 parts, the cross-linking rate of the interface self-repairing anchor material is fast, the cross-linking is high in some areas, the performance of the interface self-repairing anchor material is uneven, there is stress concentration, and it is easy to break.

[0028] In some embodiments, the interface self-repairing anchor material includes 1-3 parts by mass of a reinforcing agent, and the reinforcing agent includes nano-iridium powder (CAS: 7439-88-5) and nano-tungsten powder (CAS: 7440-33-7) in a mass ratio of 1:1. In some embodiments, the mass fraction of the reinforcing agent can be 1 part, 2 parts, or 3 parts, etc. If the mass fraction of the reinforcing agent is small, such as less than 1 part, the reinforcing effect of the interface self-repairing anchor material is not good and the strength is not high. If the mass fraction of the reinforcing agent is large, such as more than 3 parts, the interface self-repairing anchor material has high rigidity and insufficient flexibility.

[0029] In some embodiments, the interface self-repairing anchor material includes 1-2 parts by weight of a plasticizer, and the plasticizer includes heptyl nonyl phthalate (CAS: 19295-81-9) and diundecyl phthalate (CAS: 96507-86-7) in a mass ratio of 1:1. In some embodiments, the mass fraction of the plasticizer is 1 part or 2 parts, etc. If the mass fraction of the plasticizer is small, such as less than 1 part, the plasticizing effect is not good, the fluidity of each component of the interface self-repairing anchor material is reduced, and the mixing effect is not good. If the mass fraction of the plasticizer is large, such as more than 2 parts, there are many residual small molecules, forming defects and holes, which affect the mechanical strength of the interface self-repairing anchor material.

[0030] In some embodiments, the interface self-repairing anchor material includes 25-30 parts by weight of self-repairing molecules, and the self-repairing molecules include 2,2-bis[4-(2,3-dibromopropoxy)-3,5-dibromophenyl]propane (CAS: 21850-44-2), octabromodiphenyl ether (CAS: 32536-52-0), 2,4,6-tribromopyrimidine (CAS: 36847-11-7), and 2-amino-4,6-dibromopyrimidine (CAS: 856973-26-7) in a mass ratio of 1:2:1:1. In some embodiments, the mass fraction of the self-repairing molecules is 25 parts, 26 parts, 27 parts, 28 parts, 29 parts, or 30 parts. If the mass fraction of the self-repairing molecules is small, such as less than 25 parts, the self-repairing rate of the interface self-repairing anchor material is low and the repair effect is not good. If the mass fraction of the self-repairing molecules is large, such as greater than 30 parts, the mechanical strength of the interface self-repairing anchor material is affected.

[0031] The self-repairing molecules in this application are combined with 2,2-bis[4-(2,3-dibromopropoxy)-3,5-dibromophenyl]propane, octabromodiphenyl ether, 2,4,6-tribromopyrimidine, 2-amino-4,6-dibromopyrimidine, etc. to generate hydrogen bonding between the anchor rod and the anchor body, thereby enhancing the force between the anchor rod and the anchor body, increasing the anchoring force, and improving the anchoring effect of the anchor rod. When the anchor rod is impacted, the increase in its cohesive energy improves its impact resistance.

[0032] In some embodiments, the interface self-repairing anchor material includes 1-3 parts by weight of a solubilizer, wherein the solubilizer includes a dimethylsiloxane-(85-90% ethylene oxide) block copolymer (CAS: 68938-54-5) and a poly(ethylene oxide)-block-polycaprolactone (CAS: 30174-06-2) in a mass ratio of 2:1. In some embodiments, the mass fraction of the solubilizer may be 1 part, 2 parts, or 3 parts, etc. If the mass fraction of the solubilizer is small, such as less than 1 part, the components in the interface self-repairing anchor material are unevenly dispersed, and the performance of the anchor material is degraded. If the mass fraction of the solubilizer is large, such as greater than 3 parts, the mechanical properties of the interface self-repairing anchor material are affected.

[0033] This application uses multiple hydrogen-bonded self-repairing molecular materials such as 2,2-bis[4-(2,3-dibromopropoxy)-3,5-dibromophenyl]propane, octabromodiphenyl ether, 2,4,6-tribromopyrimidine, and 2-amino-4,6-dibromopyrimidine to prepare an interface self-repairing anchor material. The multiple pyrimidine and halogen molecules produce hydrogen bonds with the matrix, which enhances the internal force of the anchor matrix, increases the cohesive force, improves the mechanical properties of the anchor, and enables the anchor to have interface self-repairing properties. In field applications, when the surrounding rock of the tunnel is greatly deformed and causes cracks in the anchor, the multiple hydrogen bonds of the interface self-repairing molecules produce a self-repairing effect, so that the cracks in the anchor can be automatically repaired.

[0034] According to the embodiment of the second aspect of the present application, a method for preparing an interface self-repairing anchor material is proposed. Figure 1 , including the following steps:

[0035] S1: mixing the anchor matrix monomer material, the reinforcing agent, the self-repairing molecule, the solubilizer and the plasticizer according to the stoichiometric ratio to obtain a mixed matrix material;

[0037] S3: introducing the mixed solution A into a specific mold and heating it to 160-180° C., reacting for 60-70 minutes; cooling and solidifying the reactants to obtain the anchor material in any of the above embodiments.

[0038] Specifically, 90-100 parts of anchor matrix monomer material, 1-3 parts of reinforcing agent, 25-30 parts of self-repairing molecules, 1-3 parts of solubilizer and 1-2 parts of plasticizer are weighed in parts by mass, and evenly mixed in a dry powder mixer for 30 minutes to obtain a mixed matrix material; then 1-2 parts of anchor matrix polymerization initiator (1,1-diphenylhexyl lithium), 5-8 parts of anchor matrix cross-linking agent and 1-2 parts of anchor matrix cross-linking promoter are weighed in parts by mass, added to the mixed matrix material, stirred in a dry powder mixer for 20 minutes, heated to 130-150°C, introduced into a mold of a specific shape, heated to 160-180°C, reacted for 60 minutes, cooled and solidified, to prepare the interface self-repairing anchor material described above.
