Abstract

The invention discloses root puncture resistant filler for a waterproof roll and a production method thereof. The root puncture resistant filler is prepared by adding 10-95 percent by weight of calcium carbonate powder, 10-85 percent by weight of talcum powder, 2-50 percent by weight of wollastonite powder, 1-30 percent by weight of glass microsphere and 2-30 percent by weight of zinc oxide powder into a dry method ball miller, fully mixing for 2-3 hours and bagging. By being mixed with the glass microsphere, calcium carbonate and several other components, the compound filler can effectively improve the tension strength, the ductility and the tear strength of various waterproof rolls and reduce the maintenance frequency and the maintenance expense of the roof waterproof operation, and has higher social and economic benefits.

Description

technical field [0001] The invention relates to a filling material used for preparing building waterproof coiled material and a production method thereof. Background technique [0002] Plant roots have a strong puncture ability, which affects the life of waterproof materials. Waterproof materials without root puncture resistance cannot be used for roof planting projects. The existing modified asphalt self-adhesive waterproofing membrane generally contains modified asphalt, binders, plasticizers, tackifiers, fillers, and other additives in the formula of the oil-impregnated coating layer. Generally, it is based on the above formula Add rosin, modified rosin and other natural adhesives. Due to the different formula selection and raw material addition, there will be great differences in the performance of waterproof membranes. [0003] Existing waterproof membranes with anti-plant root puncture function need to add a metal foil layer or add a polymer sheet with fabric during ...
