Abstract

This invention discloses a high density polyethylene drainage protection plate and its manufacturing method. Sealing excrescent shell is pressed out on high density geomembrane to form a kind of film and shell continuous, and stereo space board. The geomembrane components is that high density polyethylene, flexibilizer, polyethylene wax processing agent, carbon black agglomerate, antioxidant and organic tin stabilizer, the weight percent is that high density polyethylene 85-90%, low density polyethylene 5-10%, polyethylene wax processing agent 0.3-0.5%, carbon black agglomerate 1-1.5%, antioxidant 0.5-1.0%, organic tin stabilizer 1.5-2%. The preparation method is materials mixed by high and low speed mixer, double screws extruder extrusion, pelleting single screw extruder extrusion, filtering mould shaping cooling, and mould pressing. Water source can be drained immediately by this invention.

Description

Technical field: [0001] The invention relates to a waterproof and drainage protection material, in particular to a high-density polyethylene drainage protection board and a preparation method thereof. High-density polyethylene drainage protection board is widely used in construction basement drainage protection and planting roof drainage protection, construction buildings, factories, hospitals, shopping malls ground moisture, sound insulation, shock isolation, tunnel waterproofing, drainage and other engineering fields. Background technique: [0002] According to research, in the Paleolithic Age about 50,000 years ago, the Chinese had already learned to build "sloping thatched shacks", laying thatch on "herringbone"-shaped shelves, and using the principle of slope drainage to build roofs. It is recorded in the literature that "Jie is a tile house". Archeology has confirmed that there were many types of clay tiles in the Western Zhou Dynasty. Until the 1960s, the mainstream b...
