As can be seen from a comparison of the data in Table 1 for examples 1-3 with comparative examples 1-4, the synergistic combination of nanosilica, calcium oxide, garlicin and aloe fiber powder was used in examples 1-3 to prepare sealants, the absence of nanosilica as a component in comparative example 1, the absence of calcium oxide as a component in comparative example 2, the absence of garlicin as a component in comparative example 3, and the absence of aloe fiber powder as a component in comparative example 4, whereas the variation in the notch length, the hydrophobicity and the water immersion height on the tile after 30 days for the sealants of examples 1-3 were all higher than those of comparative examples 1-4, i.e., the tear strength and the barrier properties of examples 1-3 were all higher than those of comparative examples 1-4, indicating that the solid aggregate in the sealant was not easily precipitated by the synergistic combination of nanosilica, calcium oxide, garlicin and aloe fiber powder, thereby being beneficial to improving the density uniformity of the sealant, enabling the tearing strength of the sealant to be stronger, and simultaneously being beneficial to improving the waterproof performance and the anti-permeability performance of the sealant; in addition, it is also demonstrated that only when the nano silicon dioxide, the calcium oxide, the garlicin and the aloe fiber powder are cooperatively matched together, the effects of improving the tear resistance of the sealant, improving the waterproof performance and the anti-permeability performance of the ground can be better achieved, and the tear resistance of the sealant, the waterproof performance and the anti-permeability performance of the ground are easily affected due to the lack of any component.
According to the comparison of the data of the examples 1-3 and the examples 4-5 in the table 1, the hollow glass beads and the vaseline are added to the components of the examples 4-5 compared with the components of the examples 1-3, and the length change and the hydrophobic rate of the cut of the sealant and the water immersion height of the tile after 30 days in the examples 4-5 are slightly higher than those of the examples 1-3, which shows that the hollow glass beads and the vaseline are added to cooperate with each other, so that the compactness of the sealant is improved, the tear strength of the sealant is improved, the waterproof performance and the anti-permeability of the sealant are improved, and the waterproof performance and the anti-permeability of the ground are improved.
According to the comparison of the data of examples 4-5 and examples 6-7 in Table 1, the component hollow glass microspheres are absent in example 6, the component vaseline is absent in example 7, and the length change of the cut, the hydrophobicity rate and the water immersion height on the tile after 30 days are all slightly higher than those of examples 6-7 in examples 4-5, which shows that the tear strength, the waterproof performance and the anti-permeability performance of the sealant can be better improved only when the hollow glass microspheres and the vaseline are cooperated, and the absence of any component easily affects the performance of the sealant.
According to the comparison of data of 4-5 and examples 8-10 in table 1, the components of accelerating agent, silane impregnant and fatty alcohol-polyoxyethylene ether are added in examples 8-10 compared with examples 4-5, and the length change of the cut, the hydrophobic rate and the water immersion height on the tile after 30 days of the sealant in examples 8-10 are all higher than those in examples 4-5 to a certain extent, which shows that the addition of accelerating agent, silane impregnant and fatty alcohol-polyoxyethylene ether is beneficial to improving the tear resistance, the waterproof performance and the anti-permeability performance of the sealant to a certain extent, and further beneficial to improving the waterproof performance and the anti-permeability performance of the ground to a certain extent.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
