Abstract

The invention belongs to the technical field of pipeline researches, and in particular relates to a corrosion-resistant pipeline material and a preparation method thereof. The corrosion-resistant pipeline is prepared from the following raw materials in parts by weight: 20-30 parts of UHMWPE, 20-30 parts of high density polyethylene, 20-30 parts of low density polyethylene, 3-5 parts of talc powder, 10-20 parts of an ethylene-octylene copolymer, 0.3-0.5 part of a chlorine additive, 0.1-0.5 parts of an anti-scrubbing additive and 0.1-0.3 part of an antioxidant. The abrasion value of the corrosion-resistant pipeline material is tested by means of a testing method of JC / T260-1993, and the abrasion value is only 0.05g / cm<2>, and the impact strength is 120KJ / m<2>. The preparation process is easily controlled, and raw materials and equipment are easily available, and scaled commercial process is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pipeline research, and in particular relates to a wear-resistant pipeline material and its preparation method and application. Background technique [0002] Wear-resistant pipes are wear-resistant pipes and wear-resistant pipes, which are mainly used for the transportation of abrasive materials such as pneumatic and pumped slurry. Since the conveying medium generally has the characteristics of high hardness, fast flow rate, and large flow rate, it will continue to impact, wear, and corrode the pipe wall for a long time during the conveying process, which will cause the pipe to fatigue and gradually wear out, while the wear-resistant pipe Apps solve this problem. [0003] Similar to the application of wear-resistant pipes, the invention patent 201310547204.2 discloses a wear-resistant pipe, in which an adhesive layer is arranged inside the pipe body, and a wear-resistant inner lining is arranged inside th...
