Through tests, the performance indexes of the binders of the above examples are as follows:
the above experiments show that the adhesive prepared by mixing and decocting rosin and beeswax which are used as main raw materials is improved in adhesive property to different degrees after the additive is added. After the additive tung oil is added, the bonding strength and the aging resistance strength are improved. The flow and cure speed were compared: the rubber sample added with the tung oil has better fluidity, and the improvement of the fluidity is the uniform and effective guarantee of bonding under the condition of lower room temperature. The condensation time is obviously improved. However, when the amount of the additive is too large, the greasy feeling is strong, the cohesive force is weakened, and the solidification is too slow.
Meanwhile, a plurality of base material bonding tests are carried out on the adhesive sample C-3 (example 2) added with the tung oil and the peach gum, which shows that the feasibility of the adhesive for bonding cultural relics of different base materials is better. Has wide adaptability.
| Sample numbering | Sample substrate | Sample adhesive material | Adhesive strength | Remarks for note |
| C-3 | Wood material | Stone material | 2.75MPa | Average of five groups of samples |
| C-3 | Stone material | Stone material | 2.81MPa | Average of five groups of samples |
| C-3 | Metal | Stone material | 2.18MPa | Average of five groups of samples |
| C-3 | Ceramic material | Stone material | 2.11MPa | Average of five groups of samples |
Note: in this report, C-3 is the adhesive laboratory code. After screening, it is directly referred to herein.
Tests on the time and temperature of heating and boiling indicate that the boiling temperature is 170-300 ℃, the adhesive with proper bonding strength can be obtained, and the temperature is about 280 ℃. If the boiling temperature is too high and the boiling time is too long, the adhesive is accelerated to age, the bonding strength is reduced, and the crystallization condition occurs. It should be noted that in practical applications, the reheating temperature of the adhesive and aging factors that are too long in boiling are important. Should be discarded at the right time and a new product is used.
The following describes the method of operation of the adhesive of the present invention:
1) heating to melt the binder, placing the adhesive on a heating plate with adjustable temperature, adjusting the temperature to about 220 ℃ of boiling temperature, and using the adhesive when the adhesive is fully melted into liquid;
2) the bonding surface is thoroughly cleaned by using alcohol, and if the bonding body is inorganic stone, the bonding body can be properly heated.
3) The adhesive is uniformly coated on two sides of the bonding surface, the adhesive is easy to condense, a hot air gun is needed for assisting in heating the adhesive, and the colloid is ensured to be liquid during bonding.
4) When bonding, the operation time is relatively urgent, and the bonding surface needs to be properly extruded when in contact, so as to ensure that the bonding agent is fully contacted. The excessive adhesive can overflow due to extrusion, and can be removed after curing, and can be removed by using a bamboo knife or cleaned by using alcohol.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
