Problems solved by technology

[0002] At present, because there are too many damaged mineral water barrels in the water factory, it is often impossible to use the mineral water barrels if only a crack is broken, and the waste is particularly large; therefore, the factory is eager to have a method of repairing the mineral water barrels, so that the repaired barrels can be used repeatedly and save energy. energy, and will not pollute the environment
[0003] At present, there is no professional glue for repairing mineral water buckets in the market. Some of them are repaired with epoxy glue, but the effect is very poor.
Because epoxy glue has high hardness, high brittleness and easy to break, it is not suitable for use
The common all-purpose glue in the prior art is used to repair, but the effect is not good, the all-purpose glue is too soft, the bonding strength is low, the color is yellow, and the repaired wound is not beautiful

Abstract

The invention discloses a repair glue for a mineral water barrel. The repair glue is prepared from the following components of 6 to 10% of ABS (acrylonitrile butadiene styrene) resin, 20 to 30% of hydrocarbon-pentapentane petroleum resin, 1 to 3% of white carbon black, 10 to 20% of SBS (styrene butadiene styrene) styrene butadiene rubber, 0.2 to 0.4% of antioxidant, 4 to 6% of polycarbonate resin,and 49 to 61% of solvent. The repair glue has the advantages that the safe effect is realized, and the hidden hazard of health is avoided; after repairing, the sticking strength and toughness of thescratch part are enhanced; when the crack of the mineral water barrel is repaired, the linkage property and sticking strength are realized; the hardness after sticking is improved, and the cohesion force of the formula structure is improved; the viscosity is improved, the strength after crack sticking is improved, and the antioxidant reaches the anti-aging function.

Description

technical field [0001] The invention relates to the field of repair glue, more specifically, a mineral water repair glue and a preparation method thereof. Background technique [0002] At present, because there are too many damaged mineral water barrels in the water factory, it is often impossible to use the mineral water barrels if only a crack is broken, and the waste is particularly large; therefore, the factory is eager to have a method of repairing the mineral water barrels, so that the repaired barrels can be used repeatedly and save energy. energy and will not pollute the environment. [0003] At present, there is no professional glue for repairing mineral water buckets in the market. Some of them are repaired with epoxy glue, but the effect is very poor. Because epoxy glue has high hardness and high brittleness, it is not suitable for use. Adopt common all-purpose glue to repair in the prior art, but effect is also bad, and all-purpose glue is too soft, bonding str...
