Description
Technical field
The present invention relates to building structure adhesive field, anchoring adhesive and its preparation side under more particularly to a kind of water at low temperature
Method.
Background technology
In construction, due to some irresistible factors, often plant anchor is carried out to structure sheaf.Bar planting is usual
Refer to, with the chemical adhesive using high intensity, reinforcing bar or anchor pole is produced superpower anchoring bonding force with structure sheaf, so that
Reach pre-buried effect.At present, anchoring adhesive is widely used in anchor pole, is anchored after the bar planting of reinforcing bar, and the intensity of anchoring adhesive is often determined
Determine the bond strength of reinforcing bar or anchor pole and structure sheaf.
The construction of submerged structure accounts for very big proportion in construction, and at present, domestic anchoring adhesive product is only fitted mostly
Environment for drying normal temperature, low temperature water environment, especially winter under water often cannot normal construction use, main performance
It is following deficiency：
1. the curing agent poor water resistance that anchoring adhesive is used, water absorption rate is high, anchoring adhesive gel strength degradation；
2. anchoring adhesive is poor to structure sheaf and reinforcing bar effect of impregnation under low temperature water environment, cause the reinforcing bar after plant anchor with
The anchoring bond low intensity of structure sheaf；
3. anchoring adhesive epoxy curing systems reactivity under low temperature water environment is low, and curing rate is slow, or even cannot normally consolidate
Change.
The content of the invention
For the deficiency that the lower anchoring adhesive of domestic existing low temperature water environment is used, the present invention provides bar planting under a kind of water at low temperature
Glue and preparation method thereof, it is slow to solve the underwater curing speed that anchoring adhesive occurs during bar planting is operated under water at low temperature, under colloidal property
Drop is serious, and adhesive effect of impregnation is poor, the problems such as cementitiousness is weak.
To achieve the above object, the present invention is adopted the following technical scheme that：
The present invention provides anchoring adhesive under a kind of water at low temperature, it is characterised in that by component A, B component is mixed with 2: 1 mass ratio
