In summary, according to the technical scheme of the invention, the stabilizing agent, the film forming aid and the like are added on the basis of the original quick drying agent, the coupling agent and the leveling agent, so that when the later poured concrete cracks, the pre-paved waterproof coiled material at the bottom end of the concrete forms a layer of protective film on the joint surface of the pre-paved waterproof coiled material and the concrete, the protective film has the stability in handling, and when the cracks of the concrete increase, the cracking of the pre-paved waterproof coiled material along with the cracking of the concrete is relieved. According to the invention, when the pre-paved waterproof coiled material is manufactured, the defoamer, the dispersant, the light stabilizer and the like are added, so that in the using process, the heat resistance of the anti-sticking coating of the pre-paved waterproof coiled material is improved, and the anti-sticking coating has the beneficial effects of high peeling strength, ultraviolet resistance, water immersion resistance, silt resistance, cement resistance and the like. Meanwhile, the method can be well suitable for polar environment.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
