However, the exterior wall tiles nailed on the exterior wall of the building have poor protection effect and decoration effect which is difficult to meet the expectation of people, so the exterior wall tiles are mostly paved by adopting a sticking method at present.
The external wall tile is exposed to outdoor environment and suffers from wind, sun and rain all the year round, however, the common practice of pasting the external wall tile at present is to paste the back of the external wall tile on the plastering layer of the building external wall directly after smearing uniformly with 325 cement, and then knock and tamp to wait for the cement to solidify. The inventor believes that the steps in the related art are simple, but have the defects of time and material waste, labor intensity and high cost, and particularly, the outer wall tiles are easy to fall off from the outer wall of the building when being exposed to the outdoor environment for a long time.

In combination with comparative example 1 and table 1, it can be seen that the brick-wall composite obtained by using 325% cement as a binder to adhere wall bricks becomes extremely fragile under the environmental changes of high temperature, low temperature, dry and wet, and even can not meet the adhering requirement (more than 0.5 MPa), at this time, the wall bricks are easy to fall off from the base wall surface. This shows that the test method can better simulate the long-term change of the natural environment, so that the 325 cement is degraded.
It can be seen from the combination of example 1 and comparative examples 1-3 and table 1 that the brick-wall composite obtained by using the neutral transparent silicone structural adhesive or epoxy structural adhesive alone as the adhesive to adhere the wall brick is still significantly degraded after undergoing the accelerated test, and although the adhesive strength is better than that of the control group using 325 cement as the adhesive, the adhesive strength still cannot meet the adhering requirement, i.e. the wall brick is still in a state of easy falling.
When the mixing ratio of the neutral transparent silicone structural adhesive and the epoxy structural adhesive is too high or too low, the obtained special structural adhesive still undergoes obvious degradation after undergoing an acceleration test, and the bonding strength of the special structural adhesive is not obviously different from that of the single structural adhesive, which shows that the mixing ratio has an extremely important influence on the environmental resistance of the special structural adhesive, and is shown by combining the examples 1 to 3 and the comparative examples 4 to 5 and combining the table 1. When the mixing ratio of the neutral transparent silicone structural adhesive and the epoxy structural adhesive is within a certain range, the formed special structural adhesive shows excellent environmental tolerance, and the special structural adhesive formed when the mixing ratio exceeds the range is the same as that of the common structural adhesive.
The inventor speculates that the bonding reaction between the neutral transparent silicone structural adhesive and the epoxy structural adhesive is generated under the curing action of the sodium carbonate solution, and each neutral transparent silicone structural adhesive monomer is bonded with two epoxy structural adhesives to form a new chemical bond, so that a specific mixing ratio is required.
When the concentration of the sodium carbonate solution for curing the purpose-made structural adhesive is too high, the bond strength of the obtained brick wall composite is obviously reduced after undergoing the accelerated test, which is equivalent to that of the common adhesive, as can be seen by combining example 1 and comparative example 6 with table 1. This indicates that the highly concentrated sodium carbonate solution is not curing.
In particular, as can be seen from the combination of example 1 and comparative examples 7 to 8 and from Table 1, the use of a moderately concentrated sodium chloride solution or potassium carbonate solution as the curing liquid also did not result in curing.
As can be seen from the combination of examples 1 to 4 and table 1, the mixing mass ratio of the neutral transparent silicone structural adhesive to the epoxy structural adhesive is not in a linear relationship with the environmental tolerance of the formed special structural adhesive, and the inventors found that the obtained special structural adhesive has the best environmental tolerance when the mixing mass ratio of the neutral transparent silicone structural adhesive to the epoxy structural adhesive is 1: 0.5.
It can be seen from the combination of examples 4-5 and Table 1 that the environmental resistance of the cured specialty structural adhesive is best when the sodium carbonate solution is used at a mass fraction close to 3%.
It can be seen from the combination of examples 5-6 and table 1 that the environmental tolerance of the cured special structural adhesive can be improved by using the cotton strip to attach the curing cloth to the surface of the special structural adhesive.
As can be seen by combining examples 6-7 with Table 1, the use of epoxy caulk further improves the environmental resistance of specialty construction adhesives. The inventor speculates that the epoxy resin seam beautifying agent and the epoxy structural adhesive have similar monomer structures, so that the epoxy resin seam beautifying agent and the epoxy structural adhesive have good intersolubility, the bonding effect of the seam beautifying agent and the structural adhesive is improved, meanwhile, the moisture permeating into the structural adhesive in the external environment is reduced, and the effect of improving the environmental tolerance of the special structural adhesive is further realized.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
