Abstract

The invention discloses a combined modified-asphalt root penetration resistance waterproof roll and a preparation method of the combined modified-asphalt root penetration resistance waterproof roll. The combined modified-asphalt root penetration resistance waterproof roll is compounded by a surface layer, an upper waterproof layer, a padding base layer, a lower waterproof layer and a bottom layer. The upper waterproof layer and the lower waterproof layer comprise, by weight: 20% to 60% of asphalt, 15% to 20% of machine oil, 2% to 15% of polyolefin, 3% to 15% of SBS, 10% to 25% of wollastonite powder, 1% to 5% of silicon carbide whisker powder, 1% to 5% of silicon nitride whisker powder, 1% to 10% of calcium carbonate whisker powder, 0.1% to 6% of nano-zinc oxide and 0.5% to 5.0% of chemical root resistant agent. The combined modified-asphalt root penetration resistance waterproof roll has the advantages of being high in strength, strong in impact resistance, excellent in root penetration resistance performance, heat resistant, ultraviolet-resistant, ageing-resistant, long in service life, and capable of being used for roof planting projects of a roof garden, a building floor, the top slab of the basement and the like.

Description

Technical field [0001] The invention involves a waterproof coil, especially a waterproof coil and preparation method that can resist plant roots. Background technique [0002] At present, expanding the area of greening in cities has become a general demand for the public, and roof greening technology has also entered the planning of the city.The roof garden can beautify the environment, and can purify the air. The greening of the roof and the development of related technologies has a broad prospect. [0003] The first thing that needs to be solved in roof greening technology is waterproof material production technology with root puncture function.The existing SBS modified asphalt waterproof materials and APP modified asphalt waterproof materials generally do not have anti -plant root puncture function, and because of the single formula of such waterproof coils, the strength of the coil material is low, crack resistance and aging resistance are not high.It can be easily penetrated...
