Comparison 1.
The test of 1 anchoring adhesive safe performance indexes of performance test
By anchoring adhesive prepared in the above embodiments according to quality standard, its safe performance indexes is tested, as a result such as
Shown in following table:
1 anchoring adhesive safe performance indexes of table
Bond strength 1 in above-mentioned table indicates: Ribbed Bar and concrete is glutinous under C30 ∮ 25L=150mm drawing condition
Knotting strength；Bond strength 2 indicates: the bond strength of Ribbed Bar and concrete under C60 ∮ 25L=125mm drawing condition.
The difference of embodiment 1-5 is only that the difference of the polymerizable modifying agent of olefinic, and comparative example 1, which does not add olefinic, to gather
Close modifying agent.According to the above results as can be seen that the polymerizable modifying agent of olefinic selects acrylic acid, methyl methacrylate, epoxy
When the combination of acrylate and urethane acrylate, effect is best.When olefinic polymerizable modifying agent selection epoxy acrylate,
When urethane acrylate and acrylic or methacrylic acid methyl esters, as shown in the result of embodiment 1 or embodiment 2, anchoring adhesive
Performance parameter it is still fine.When in the polymerizable modifying agent of olefinic without epoxy acrylate, as described in Example 4, anchoring adhesive
Shear strength significantly reduce；When in the polymerizable modifying agent of olefinic without urethane acrylate, such as the result institute of embodiment 5
Show, the viscosity of anchoring adhesive is declined.Therefore, available to draw a conclusion according to above-mentioned experiment: 1, olefinic is polymerizable changes for addition
Property agent anchoring adhesive of the anchoring adhesive than not adding olefinic polymerizable modifying agent preparation colloidal property and to cohere ability good；2, olefinic
Polymerizable modifying agent urethane acrylate can enhance the ability of cohering of anchoring adhesive, but elasticity is bad, and brittleness is larger, only again
The epoxy acrylate of certain number is added, elasticity can be improved and the problem of brittleness, it is good to prepare bonding dynamics, elastic and soft
The all good anchoring adhesive of toughness.
The test of 2 heat and moisture aging resistance of performance test
Anchoring adhesive prepared by embodiment 1-3 and comparative example 1 is bonded tensile shear carbon steel by GB/T 7124-1986
After test piece, solidify at room temperature.Antirust treatment (exposing bonding site) is done into the shearing test piece of after curing completely, is put into damp and hot old
Change chamber, degradation is carried out in (50 ± 2) DEG C, the environment of 95% or more humidity.It is old by GB/T 7124-1986 measurement
The shear strength under test piece room temperature after change, and compared with the test piece before aging.As a result as shown in the table:
The test of 2 heat and moisture aging resistance of table
| Embodiment 1 | Embodiment 2 | Embodiment 3 | Comparison 1 | |
| Shear strength/MPa before aging | 22.3 | 25.1 | 29.2 | 16.7 |
| Shear strength/MPa after aging 500h | 22.0 | 24.0 | 29.0 | 14.3 |
| Shear strength/MPa after aging 2000h | 21.3 | 22.8 | 28.7 | 8.9 |
| Shear strength/MPa after aging 5000h | 21.0 | 22.6 | 28.5 | 7.2 |
It can be seen that the anchoring adhesive of the polymerizable modifying agent preparation of addition olefinic than not modified plant according to above-mentioned test result
Muscle glue heat and moisture aging resistance significantly improves.Reason is analyzed, is because of addition 3 parts of acrylic acid, 6 parts of methyl methacrylate, ring
8 parts of oxypropylene acid esters, 13 parts of the urethane acrylate conduct polymerizable modifying agent of olefinic, so that the crosslinking in cross-linking process is close
Spend moderate, cohesive force, elasticity and flexibility compare balance, avoid pursuing the high-intensitive bullet for cohering ability and ignoring colloid simply
Property and ageing-resistant performance.
The test of 3 curing performance of performance test
By anchoring adhesive prepared by the application most preferred embodiment 3 and certain commercially available chemical materials company anchoring adhesive product-
The curing time of SHB injecting type anchoring adhesive and operable time are compared, as a result as shown in the table:
3 anchoring adhesive curing performance of table
It can be seen from the above results when environment temperature is-5-5 DEG C lower, anchoring adhesive prepared by the present invention embodies not
Advantage in terms of curing performance out is identical as commercially available SHB anchoring adhesive curing time.But when environment temperature is increased to 20-40
DEG C when, commercially available anchoring adhesive curing time is respectively 50,30,20min, and the curing time of embodiment 3 is 41,20,11min, Gu
The change time significantly shortens, and there is no shorten for operable time.The improvement of this curing time carries out engineering in the hot summer
Will be highly beneficial when repairing, it not only saves maintenance time, higher temperature softening colloid is more avoided, to reduce cohesion
Degree.
Performance test 4 can be with rust service performance test
This experiment anchoring adhesive used is anchoring adhesive prepared by embodiment 3, by the reinforcing bar of different band rust area according to applying
Work standard bar planting carries out live pullout tests, the influence by the size judgement of draft with rust area for bar planting effect.
The scene pullout tests rule is as follows: anchoring adhesive is carried out according to GB 50367-2013 " concrete structure reinforcement design specification "
Test, strength grade of concrete used are C30, and reinforcing bar is the hot rolling plain bar of HPB300, diameter 25mm, implantation depth
200mm, maintenance measured draft and damage -form after 7 days.Test result is as follows shown in table:
Table 4 can be with rust service performance test
| Draft (KN) | Damage -form | |
| Band rust area 0 | 240.7 | Taper is destroyed, and reinforcing bar is extracted |
| Band rust area 1% | 237.3 | Taper is destroyed, and reinforcing bar is extracted |
| Band rust area 2% | 236.8 | Taper is destroyed, and reinforcing bar is extracted |
| Band rust area 4% | 233.9 | Taper is destroyed, and reinforcing bar is extracted |
| Band rust area 6% | 231.0 | Taper is destroyed, and reinforcing bar is extracted |
| Band rust area 8% | 180.3 | Taper is destroyed, and reinforcing bar is extracted |
It can be seen from the data in above-mentioned table when band rust area is 1-6%, although draft decreases,
But reduction is not significant, has 240.7KN to be reduced to 231.0KN, can be used normally in construction.When band rust area is 8%,
Draft is remarkably decreased, and has been unable to normal use, could be used after needing to remove rust staining.Therefore, prepared by the application
Anchoring adhesive for rust area≤6% reinforcing bar can normal use, do not influence bar planting effect.
