A root puncture-resistant waterproof membrane for planting roofs and its production and processing technology

Abstract

The invention provides a planted roof root-resistance waterproof roll which is composed of 28-30 parts of asphalt, 2-6 parts of SBS (styrene butadiene styrene), 3-6 parts of SBR (styrene butadiene rubber), 1.6-7 parts of APP (ammonium polyphosphate), 15-23 parts of mixed grease, 3-6 parts of fire retardant, 10-13 parts of anti-migration plasticizer, 23-24 parts of polyvinyl chloride resin, 8-10 parts of portland cement powder, 1.0-1.2 parts of nano-zinc oxide, 1-5 parts of dibasic lead phosphate, 2-8 parts of terpolymer resin, 1-5 parts of ABS (acrylonitrile butadiene styrene) resin, 15-22 parts of 909 anti-freeze binder, 10-12 parts of polypropylene fibers and 0.8-1.2 parts of chemical root retardant. The roll is capable of resisting root puncture without influences on normal growth of plants, is waterproof for long term, is capable of forming a high-intensity waterproof layer with high pressure water resistance capacity, and further is fatigue resistant and is high in tensile strength; besides, due to the SBS modified asphalt coating layer with strong original nature, the roll has the advantages of high adaptability to shrinkage and crack of the base layer, excellent high-temperature and low-temperature resistance capacity, high adaptability to cold and hot regions, and high corrosion, mildew and weather resistance.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to a root puncture-resistant waterproof coiled material for planting roofs and its production and processing technology. Background technique [0002] Planted roof technology has been recognized by more and more people as an energy-saving, ecological, and green emerging technology. Although the "sky villas" reported in Beijing some time ago violated the relevant regulations of urban planning, it is not difficult to see from it that At present, roof greening is already a technology that has been promoted. [0003] In relatively large cities such as Beijing, Shanghai, and Chengdu, people's needs are high, and the proportion of urban planted roof applications has increased significantly every year. Some cities have used planted roofs as one of the important measures to control air pollution. [0004] Therefore, planted roofs will have the prospect of being widely promoted and ap...

Problems solved by technology

[0006] At present, traditional root puncture-resistant waterproof membranes are poor in impact resistance and corrosion resistance, and cracking and water leakage will probably occur after more than 10 years. However, after 10 years, the vegetation growth is just in the best state, and the greening effect is better. Let's dig again The amount of repair work is large and complicated, and the construction remains unchanged, so it is impossible to complete the long-term planning of a century-old landmark building
