Effect example
The following table 1 gives the analysis results of the water-impermeable properties and the adhesive properties of the anti-seepage architectural coatings of examples 1 to 3 and comparative examples 1 to 3 according to the present invention.
TABLE 1
From comparison of the experimental data of examples 1, 2, 3 and comparative example 1 in table 1, it can be found that the tear strength of examples 1, 2, 3 is high compared with comparative example 1, which illustrates that the asphalt is heated and treated at low pressure, so that harmful gas is more easily removed from the asphalt, and then oxidized, so that unsaturated bonds in the asphalt are oxidized into epoxy groups or other oxygen-containing groups, thereby participating in subsequent crosslinking and curing, and thus improving the adhesive property; from comparison of experimental data of examples 1, 2 and 3 and comparative example 2, it can be found that the comparative example 2 of examples 1, 2 and 3 has no water penetration phenomenon and high tearing strength, which indicates that the waterproof agent prepared by reacting hydrogen terminated silicone oil and allyltrimethoxysilane has good waterproof effect, and can be used as a silane coupling agent to improve bonding performance.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
