NOVELTY - Reinforced wear-resistant PE drainage pipe comprises 70-90 pts. wt. HDPE high density polyethylene, 25-35 pts. wt. LLDPE linear low density polyethylene, 10-15 pts. wt. nano graphene, 3-5 pts. wt. polyaniline modified bentonite, 1-2 pts. wt. titanate coupling agent, 2-3 pts. wt. titanium dioxide loaded with antibacterial agent, 1-3 pts. wt. antioxidant, 1-2 pts. wt. anti-wear agent. The preparation of the reinforced wear-resistant PE drainage pipe for trenchless construction includes introducing HDPE high-density polyethylene into the high-speed mixer by weight and mixed at a speed of 60-80r/min for 5-10 minutes. When the HDPE high-density polyethylene is dispersed, make LLDPE linear low-density polyethylene raw materials and HDPE high-density polyethylene raw materials mixed in a high-speed mixer at 100-120r/min for 30-40 minutes to obtain reinforcement for first trenchless construction mixed base material for wear-resistant PE drainage pipe. USE - Reinforced wear-resistant PE drainage pipe for trenchless construction. ADVANTAGE - The reinforced wear-resistant PE drainage pipe has long-lasting and effective conductive properties. It has a good crosslinking effect with HDPE high density polyethylene and LLDPE linear low density polyethylene, which can improve the strength of polymer materials, enhance the thermal stability, wear resistance and corrosion resistance of materials, and greatly improve the various properties of reinforced wear-resistant PE drainage pipes for excavation construction. DETAILED DESCRIPTION - The 85 pts. wt. organic treated bentonite is added to the preparation tank according to weight, and then added 6 pts. wt. aniline, 4 pts. wt. 2mol/L hydrochloric acid solution and 4 pts. wt. 2mol/L ammonium persulfate solution to the preparation tank, and let stand for 6-8 hours to obtain a precipitate, and then introduce the precipitate into hopper one (501). The obtained sediment is heated and dried by the heating tube (502) in the hopper one, and the dried sediment is introduced into the pre-crushing on the crushing rack through the screw barrel (5). The precipitate is crushed by the crushing roller set in the pre-crushing cavity (3) to obtain the polyaniline modified bentonite coarse material, and the polyaniline modified bentonite coarse material is introduced into the grinding cavity (2). The polyaniline modified bentonite coarse material is ground through the grinding roller set in the grinding chamber to obtain polyaniline modified bentonite fine material, and introduce the obtained polyaniline modified bentonite fine material into the discharge hopper (4). The polyaniline modified bentonite fine material is filtered through an 800-mesh vibrating screen (402) in the discharge hopper to obtain polyaniline modified bentonite to obtain second mixed base material, and added titanate coupling agent, antibacterial agent-loaded titanium dioxide, antioxidants and wear resistant agents to second mixed base material to make the titanate coupling agent, titanium dioxide loaded with antibacterial agent, antioxidant and anti-wear agent in a high-speed mixer. The spray water is used to cool the shaped pipe blank and cut to length to obtain the reinforced wear-resistant PE drainage pipe for trenchless construction.
