Preparation And Application Of Root-resistant Puncture Waterproof Coil Material

The resistant root-piercing waterproof layer is one of the basic structural layers of the building roof and garage greening and is usually composed of an ordinary waterproof layer and a resistant root-piercing layer.The ordinary waterproof material is in the resistant root-piercing waterproof material.The lower layer,The construction process of the waterproof layer is the key process for the success of the entire roof and garage greening.The preparation technology of resistant root-piercing waterproof coil is studied in this paper,and the emphasis is on the chemical root-resistant self-adhesive modified asphalt waterproof coil(that is,the waterproof coil that uses the chemical root-blocking agent to perform the root-blocking behavior).The study of the waterproofing coil’s own strength and chemical resistance to plant root puncture was conducted.During the test process,the material ratio was continuously revised,and various performance tests were performed to study the best ratio,and an appropriate amount of outdoor actual construction was carried out..In order to achieve the ultimate goal of increasing the diversity of selection of root-piercing waterproof materials in practical production and life.In this paper,chemical resistant self-adhesive modified asphalt waterproofing rolls are applied to plant roof or garage greening waterproofing project.A 6-month root puncture test was conducted with forsythia forsythia as experimental plant.Compared with the two-year plant root puncture test with Pyracus,the test period was shortened,the time cost was reduced and the product was promoted.After a series of test results and analysis,and after the small-scale use of production,the following conclusions are drawn:1.The best ratio of the self-adhesive layer in this test is 50%asphalt,5%SBS5%,15%rubber filling oil,SBR5%,9%terpene resin,and 15%filling material.2.The expected effect of root-resistant puncture can be achieved by adding chemical blocker to 0.25%.The amount of addition should be controlled at 0.25%-0.5%and should not exceed 1.0%.3.The performance of the resistant root-piercing waterproof coil prepared in this study meets the requirements of the national standard GB/T 19250-2013,and the various mechanical properties are good.They have waterproof-and moisture-proof functions based on waterproof materials and have root-piercing functions.Self-adhesive chemical-resistant penetrating modified asphalt waterproof rolls can be used in actual production.
