The bonding method of the metal skeleton and the rubber in the second to tenth embodiments is the same as that in the first embodiment, except that the mass fraction ratio of each raw material in the surface treating agent in the present embodiment is different, as shown in the following table:
| examples | D6890/wt％ | Triethanolamine/wt% | Monoethanolamine/wt% | Water/wt% | Destructive power/KN |
| 1 | 5 | 1 | 0 | 94 | 23.4 |
| 2 | 5 | 0 | 1 | 94 | 23.2 |
| 3 | 4 | 4 | 0 | 92 | 26.1 |
| 4 | 4 | 0 | 4 | 92 | 25.8 |
| 5 | 6 | 5 | 0 | 89 | 26.7 |
| 6 | 6 | 0 | 5 | 89 | 26.5 |
| 7 | 7 | 3 | 0 | 90 | 24.7 |
| 8 | 7 | 0 | 3 | 90 | 24.6 |
| 9 | 8 | 2 | 0 | 90 | 24.4 |
| 10 | 8 | 0 | 2 | 90 | 24.5 |
Comparative examples one to five
The bonding method of the metal skeleton and the rubber in this comparative example is the same as that in the first example, except that the mass fraction ratio of each raw material in the surface treating agent in this comparative example is different, as shown in the following table:
| comparative example | D6890/wt％ | Water/wt% | Destructive power/KN |
| 1 | 4 | 96 | 18.9 |
| 2 | 5 | 95 | 19.1 |
| 3 | 6 | 94 | 19.4 |
| 4 | 7 | 93 | 19.6 |
| 5 | 8 | 92 | 19.7 |
The addition of triethanolamine or monoethanolamine in combination with examples one to ten and comparative examples one to five can further enhance the metal-rubber binding force of the surface treatment agent and improve the destructive power of the product.
Comparative examples six to nine
| Comparative example | D6890/wt％ | Triethanolamine/wt% | Water/wt% | Destructive power/KN |
| 6 | 1 | 3 | 96 | 18..4 |
| 7 | 13 | 5 | 82 | 26.3 |
| 8 | 6 | 7 | 87 | 25.4 |
| 9 | 6 | 9 | 85 | 25.1 |
In the case of the combination of examples one to ten and comparative examples six to nine, when the mass fraction of the addition of the Kemmett's D6890 is less than 1, the improvement of the destructive power of the product is limited. This is because a mass fraction of less than 1 means that the amount of the kemitter D6890 added is small, and the effect of enhancing the destructive power of the product cannot be sufficiently exerted. On the other hand, when the mass fraction of the kemitter D6890 is more than 8 parts, the increase of the destructive power to the product is not obvious, and the increase and waste of the raw material cost are caused. This is because a mass fraction of greater than 8 parts indicates that the amount of chemiter D6890 added is greater than the optimal formulation required for the product, not only does the product destructive power not be further enhanced, but also raw material cost and resources are wasted.
Likewise, when the mass fraction of triethanolamine is greater than 5, the product destructive power is not increased but there is a small decrease.
Experimental example
In this embodiment, after the rubber coating piece is formed by drying, the rubber coating piece needs to be vulcanized to form a rubber procedure after entering a turnover room, and when rust on the surface of the rubber coating piece reaches a rust point visible to naked eyes, the bonding between the metal framework and the rubber is affected, namely, the rubber is regarded as rusted. The period of time from when the coated member is dried to when the coated member is rusted is called the rusting time.
The coated pieces of examples one to ten and comparative examples one to five above were subjected to rust tests, which were conducted under room temperature conditions, with different ambient humidity, wherein 60% humidity corresponds to sunny days, more than 60% humidity corresponds to overcast and rainy weather, and the test results were rounded off as shown in the following table:
in summary, the addition of triethanolamine or monoethanolamine can increase the weather resistance of the surface treatment agent, promote the antioxidation capability of the glue coated piece, and widen the process width, thereby prolonging the service life of the glue coated piece and improving the performance stability and reliability of the glue coated piece.
