Table 3 bonding strength test table (MPa)
/>
As can be seen from the combination of example 6, comparative example 1, comparative example 4 and comparative example 7 and the combination of table 3, the bonding strength of the new and old interfaces can be effectively improved by adding the aqueous acrylic resin emulsion, the mulberry silk fiber and the tert-butyl glycidyl ether as the interface bonding agents, mainly because the aqueous acrylic resin emulsion plays a role in bonding and permeates into the old pavement gaps, the mulberry silk fiber and the tert-butyl glycidyl ether enter the old pavement gaps along with the aqueous acrylic resin emulsion, and when the aqueous acrylic resin emulsion is cured under the influence of the curing agent, the tert-butyl glycidyl ether molecular chain is curled to enable the bonding strength among the mulberry silk fiber, the aqueous acrylic resin and the inner walls of the pavement gaps, so that the bonding strength among the new and old interfaces is effectively improved, and the situation that the corners of the new pavement are cracked again is reduced.
As can be seen from the combination of example 6 and comparative examples 1-3 and Table 3, the addition of the aqueous acrylic resin emulsion, mulberry silk fiber and t-butyl glycidyl ether as interfacial adhesives significantly improved the adhesion properties as compared to the addition of the two materials.
As can be seen from the combination of example 6, comparative example 3, comparative examples 5 to 7 and Table 3, the anhydrous polypropylene resin emulsion was mainly used, and the mulberry silk fiber and t-butyl glycidyl ether had substantially no effect on the bonding strength between the old and new interfaces.
It can be seen from the combination of examples 2 to 10 and Table 3 that the adhesive properties of the grouting material can be effectively improved by adjusting the addition ratio of the aqueous acrylic resin emulsion, the mulberry silk fiber and the tert-butyl glycidyl ether.
The present embodiment is only for explanation and not limitation of the present application, and modifications of the present embodiment without creative contribution can be made by those skilled in the art after reading the present specification as required, but are protected by patent laws within the scope of claims of the present application.
