From the test data of examples 5 to 8, it can be seen that compounding PVA 26-99 (L) and PVA20-99 (H) as polyvinyl alcohol improves the strength of the water-blocking tape, and makes the termite and rat proofing effect of the water-blocking tape longer. The preparation method is characterized in that the PVA 26-99 (L) and the PVA20-99 (H) are compounded to improve the bonding performance of the termite and rat preventing prepolymer liquid and the semiconductive non-woven fabric, and improve the solubility and the stability of diallyl thiosulfinate and trans-8-methyl-N-vanillyl-nonenamide. And the breaking strength of the water-blocking tape is higher when the mass ratio of PVA 26-99 (L) to PVA20-99 (H) is 1.4.
From the test data of examples 8 to 10, it can be seen that the compounding of propylenediamine and polypropylene glycol glycidyl ether as a crosslinking agent improves the stability of the crosslinked three-dimensional network structure, thereby improving the strength of the water-blocking tape.
The specific embodiments are only for explaining the present application and are not limiting to the present application, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the claims of the present application.
